+# feather_sensor_lte
+
+A Particle project named feather_sensor_lte
+
+## Welcome to your project!
+
+Every new Particle project is composed of 3 important elements that you'll see have been created in your project directory for feather_sensor_lte.
+
+#### ```/src``` folder:  
+This is the source folder that contains the firmware files for your project. It should *not* be renamed. 
+Anything that is in this folder when you compile your project will be sent to our compile service and compiled into a firmware binary for the Particle device that you have targeted.
+
+If your application contains multiple files, they should all be included in the `src` folder. If your firmware depends on Particle libraries, those dependencies are specified in the `project.properties` file referenced below.
+
+#### ```.ino``` file:
+This file is the firmware that will run as the primary application on your Particle device. It contains a `setup()` and `loop()` function, and can be written in Wiring or C/C++. For more information about using the Particle firmware API to create firmware for your Particle device, refer to the [Firmware Reference](https://docs.particle.io/reference/firmware/) section of the Particle documentation.
+
+#### ```project.properties``` file:  
+This is the file that specifies the name and version number of the libraries that your project depends on. Dependencies are added automatically to your `project.properties` file when you add a library to a project using the `particle library add` command in the CLI or add a library in the Desktop IDE.
+
+## Adding additional files to your project
+
+#### Projects with multiple sources
+If you would like add additional files to your application, they should be added to the `/src` folder. All files in the `/src` folder will be sent to the Particle Cloud to produce a compiled binary.
+
+#### Projects with external libraries
+If your project includes a library that has not been registered in the Particle libraries system, you should create a new folder named `/lib/<libraryname>/src` under `/<project dir>` and add the `.h`, `.cpp` & `library.properties` files for your library there. Read the [Firmware Libraries guide](https://docs.particle.io/guide/tools-and-features/libraries/) for more details on how to develop libraries. Note that all contents of the `/lib` folder and subfolders will also be sent to the Cloud for compilation.
+
+## Compiling your project
+
+When you're ready to compile your project, make sure you have the correct Particle device target selected and run `particle compile <platform>` in the CLI or click the Compile button in the Desktop IDE. The following files in your project folder will be sent to the compile service:
+
+- Everything in the `/src` folder, including your `.ino` application file
+- The `project.properties` file for your project
+- Any libraries stored under `lib/<libraryname>/src`

+ *
+ *
+ * \section asfdoc_sam0_system_clock_module_overview Module Overview
+ * The SAM devices contain a sophisticated clocking system, which is designed
+ * to give the maximum flexibility to the user application. This system allows
+ * a system designer to tune the performance and power consumption of the device
+ * in a dynamic manner, to achieve the best trade-off between the two for a
+ * particular application.
+ *
+ * This driver provides a set of functions for the configuration and management
+ * of the various clock related functionality within the device.

+ *		<td>SAMD21, SAMR21, SAMD10, SAMD11, SAMDAx</td>
+ *	</tr>
+ * </table>
+ * \note The specific features are only available in the driver when the
+ * selected device supports those features.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_clock_sources Clock Sources
+ * The SAM devices have a number of master clock source modules, each of
+ * which being capable of producing a stabilized output frequency, which can then
+ * be fed into the various peripherals and modules within the device.
+ *
+ * Possible clock source modules include internal R/C oscillators, internal
+ * DFLL modules, as well as external crystal oscillators and/or clock inputs.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_cpu_clock CPU / Bus Clocks
+ * The CPU and AHB/APBx buses are clocked by the same physical clock source
+ * (referred in this module as the Main Clock), however the APBx buses may
+ * have additional prescaler division ratios set to give each peripheral bus a
+ * different clock speed.
+ *
+ * The general main clock tree for the CPU and associated buses is shown in
+ * \ref asfdoc_sam0_system_clock_module_clock_tree "the figure below".

+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_clock_masking Clock Masking
+ * To save power, the input clock to one or more peripherals on the AHB and APBx
+ * buses can be masked away - when masked, no clock is passed into the module.
+ * Disabling of clocks of unused modules will prevent all access to the masked
+ * module, but will reduce the overall device power consumption.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_gclk Generic Clocks
+ * Within the SAM devices there are a number of Generic Clocks; these are used to
+ * provide clocks to the various peripheral clock domains in the device in a
+ * standardized manner. One or more master source clocks can be selected as the
+ * input clock to a Generic Clock Generator, which can prescale down the input
+ * frequency to a slower rate for use in a peripheral.
+ *
+ * Additionally, a number of individually selectable Generic Clock Channels are
+ * provided, which multiplex and gate the various generator outputs for one or
+ * more peripherals within the device. This setup allows for a single common
+ * generator to feed one or more channels, which can then be enabled or disabled
+ * individually as required.

+ * }
+ * \enddot
+ *
+ * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_generators Generic Clock Generators
+ * Each Generic Clock generator within the device can source its input clock
+ * from one of the provided Source Clocks, and prescale the output for one or
+ * more Generic Clock Channels in a one-to-many relationship. The generators
+ * thus allow for several clocks to be generated of different frequencies,
+ * power usages, and accuracies, which can be turned on and off individually to
+ * disable the clocks to multiple peripherals as a group.
+ *
+ * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_channels Generic Clock Channels
+ * To connect a Generic Clock Generator to a peripheral within the
+ * device, a Generic Clock Channel is used. Each peripheral or
+ * peripheral group has an associated Generic Clock Channel, which serves as the
+ * clock input for the peripheral(s). To supply a clock to the peripheral
+ * module(s), the associated channel must be connected to a running Generic
+ * Clock Generator and the channel enabled.

+ * \section asfdoc_sam0_i2s_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ * \section asfdoc_sam0_i2s_module_overview Module Overview
+ *
+ * The I2S provides bidirectional, synchronous, digital audio link with external
+ * audio devices through these signal pins:
+ *  - Serial Data (SDm)
+ *  - Frame Sync (FSn)
+ *  - Serial Clock (SCKn)
+ *  - Master Clock (MCKn)
+ *
+ * The I2S consists of 2 Clock Units and 2 Serializers, which can be separately
+ * configured and enabled, to provide varies functionalities as follow:
+ *  - Communicate to Audio CODECs as Master or Slave, or provides clock and
+ *    frame sync signals as Controller
+ *  - Communicate to DAC or ADC through dedicated I2S serial interface
+ *  - Communicate to multi-slot or multiple stereo DACs or ADCs, via
+ *    Time Division Multiplexed (TDM) format
+ *  - Reading mono or stereo MEMS microphones, using the Pulse Density
+ *    Modulation (PDM) interface
+ *
+ * The I2S supports compact stereo data word, where left channel data bits are
+ * in lower half and right channel data bits are in upper half. It reduces the
+ * number of data words for stereo audio data and the DMA bandwidth.
+ *
+ * In master mode, the frame is configured by number of slots and slot size, and
+ * allows range covering 16fs to 1024fs MCK, to provide oversampling clock to an
+ * external audio CODEC or digital signal processor (DSP).
+ *
+ * A block diagram of the I2S can be seen in
+ * \ref asfdoc_sam0_i2s_module_block_diagram "the figure below".
+ *
+ * \anchor asfdoc_sam0_i2s_module_block_diagram
+ * \image html i2s_blocks.svg "I2S Block Diagram"
+ *
+ * This driver for I2S module provides an interface to
+ *  - initialize and control I2S module
+ *  - configure and control the I2S Clock Unit and Serializer
+ *  - transmit/receive data through I2S Serializer
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_clocks Clocks
+ *
+ * To use I2S module, the I2S bus interface clock (clk_i2s) must be enabled via
+ * Power Manager.
+ *
+ * For each I2S Clock Unit, a generic clock (gclk_i2s_n) is connnected. When I2S
+ * works in master mode the generic clock is used. It should be prepared before
+ * clock unit is used. In master mode the input generic clock will be used as
+ * MCK for SCKn and FSn generation, in addition, the MCK could be devided and
+ * output to I2S MCKn pin, as oversampling clock to external audio device.
+ *
+ * The I2S Serializer uses clock and control signal from Clock Unit to handle
+ * transfer. Select different clock unit with different configurations allows
+ * the I2S to work as master or slave, to work on non-related clocks.
+ *
+ * When using the driver with ASF, enabling the register interface is normally
+ * done by the \c init function.
+ * The gclk source for the asynchronous domain is normally configured and set
+ * through the _configuration struct_ / _init_ function. 
+ * If gclk source != 0 is used, this source has to be configured and enabled
+ * through invoking the system_gclk driver function when needed, or modifying
+ * conf_clock.h to enable it at the beginning.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_frame Audio Frame Generation
+ *
+ * Audio sample data for all channels are sent in frames, one frame can consist
+ * 1 - 8 slots where each slot can be configured to a size 8-bit, 16-bit, 24-bit
+ * or 32-bit. The audio frame synch clock is generated by the I2S Clock unit in
+ * the master/controller mode. The frame rate (or frame sync frequency) is
+ * calculated as follow:
+ *
+ * FS = SCK / number_of_slots / number_of_bits_in_slot
+ *
+ * The serial clock (SCK) source is either an external source (slave mode) or
+ * generated by the I2S clock unit (controller or master mode) using the MCK as
+ * source.
+ *
+ * SCK = MCK / sck_div
+ * \note SCK generation division value is MCKDIV in register.
+ *
+ * MCK is either an external source or generated using the gclk input from a
+ * generic clock generator.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_mode Master, Controller and Slave modes
+ *
+ * The i2s module has three modes: master, controller and slave.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_mst Master
+ * In master mode the module will control the data flow on the i2s bus and can
+ * be responsible for clock generation. The Serializers are enabled and will
+ * transmit/receive data. On a bus with only master and slave the SCK and FS
+ * clock signal will be outputted on the SCK and FS pin on the master module.
+ * MCK can optionally be outputted on the MCK pin, if there is a controller
+ * module on the bus the SCK, FS and optionally the MCK clock is sourced from
+ * the same pins. Serial data will be trancieved on the SD pin in both
+ * scenarios.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_ctl Controller
+ * In controller mode the module will generate the clock signals, but the
+ * Serializers are disabled and no data will be transmitted/received by the
+ * module in this mode. The clock signals is outputted on the SCK, FS and
+ * optionally the MCK pin.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_slv Slave
+ * In slave mode the module will use the SCK and FS clock source from the master
+ * or the controller which is received on the SCK and FS pin. The MCK can
+ * optionally be sourced externally on the MCK pin. The Serializers are enabled
+ * and will tranceive data on the SD pin. All data flow is controlled by the
+ * master.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_chg Switch modes
+ * The mode switching between master, controller and slave modes are actually
+ * done by modifying the source mode of I2S pins.
+ * The source mode of I2S pins are selected by writing corresponding bits in
+ * CLKCTRLn.
+ * Since source mode switching changes the direction of pin, the mode must be
+ * changed when the I2S Clock Unit is stopped.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_data Data Stream Reception/Transmission
+ *
+ * The I2S module support several data stream formats:
+ * - I2S format
+ * - Time Division Multiplexed (TDM) format
+ * - Pulse Density Modulation (PDM) format (reception only)
+ *
+ * Basically the I2S module can send several words within each frame, it's more
+ * like TDM format. With adjust to the number of data words in a frame, the FS
+ * width, the FS to data bits delay, etc., the module is able to handle I2S
+ * compliant data stream.
+ *
+ * Also the Serializer can receive PDM format data stream, which allows the I2S
+ * module receive 1 PDM data on each SCK edge.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_i2s I2S Stream Reception/Transmission
+ *
+ * For 2-channel I2S compliant data stream format the i2s module uses the FS
+ * line as word select (WS) signal and will send left channel data word on low
+ * WS level and right channel data word on high WS level as specified in the I2S
+ * standard. The supported word sizes are 8-, 16-, 18-, 20-, 24- and 32- bit.
+ *
+ * Thus for I2S stream, the following settings should be applied to the module:
+ *  - Data starting delay after FS transition : one SCK period
+ *  - FS width : half of frame
+ *  - Data bits adjust in word : left-adjusted
+ *  - Bit transmitting order : MSB first
+ *
+ * Following is an example for I2S application connections and waveforms. See
+ * \ref asfdoc_sam0_i2s_module_i2s_example_diagram "the figure below".
+ *
+ * \anchor asfdoc_sam0_i2s_module_i2s_example_diagram
+ * \image html i2s_example.svg "I2S Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_tdm TDM Stream Reception/Transmission
+ * In TDM format, the module sends several data words in each frame. For this
+ * data stream format most of the configurations could be adjusted:
+ *  - Main Frame related settings are as follow:
+ *   - Frame Sync (FS) options:
+ *    - the active edge of the FS (or if FS is inverted before use)
+ *    - the width of the FS
+ *   - the delay between FS to first data bit
+ *  - Data alignment in slot
+ *  - The number of slots and slot size can be adjusted, it has been mentioned
+ *    in \ref asfdoc_sam0_i2s_module_overview_frame
+ *  - The data word size is controlled by Serializer, it can be chosen among
+ *    8, 16, 18, 20, 24 and 32 bits.
+ *
+ * The general TDM waveform generation is as follow:
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_wave_diagram
+ * \image html tdm_wave.svg "TDM Waveform generation"
+ *
+ * Some other settings could also be found to set up clock, data formatting and
+ * pin mux.
+ * refer to \ref i2s_clock_unit_config "Clock Unit Configurations"
+ * and \ref i2s_serializer_config "Serializer Configurations" for more
+ * details.
+ *
+ * Following is examples for different application use cases.
+ *
+ * See \ref asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram "here" for
+ * the Time Slot Application connection and waveform example.
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram
+ * \image html tdm_timeslot_example.svg "Codec Example Diagram"
+ *
+ * See \ref asfdoc_sam0_i2s_module_tdm_codec_example_diagram "here" for the
+ * Codec Application connection and waveform example.
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_codec_example_diagram
+ * \image html tdm_codec_example.svg "Time Slot Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_pdm PDM Reception
+ * The I2S Serializer integrates PDM reception feature, to use this feature,
+ * simply select PDM2 mode in Serializer configuration. In PDM2 mode, it assumes
+ * two microphones are input for stereo stream. The left microphone bits will
+ * be stored in lower half and right microphone bits in upper half of the data
+ * word, like in compact stereo format.
+ *
+ * See \ref asfdoc_sam0_i2s_module_pdm_example_diagram "following figure" for an
+ * example of PDM Microphones Application with both left and right channel
+ * microphone connected.
+ *
+ * \anchor asfdoc_sam0_i2s_module_pdm_example_diagram
+ * \image html pdm_example.svg "Time PDM2 Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_fmt MONO and Compact Data
+ * The I2S Serializer can accept some pre-defined data format and generates
+ * the data stream in specified way.
+ *
+ * When transmitting data, the Serializer can work in MONO mode: assum input
+ * is single channel mono data on left channel and copy it to right channel
+ * automatically.
+ *
+ * Also the I2S Serializer can support compact stereo data word. The data word
+ * size of the Serializer can be set to \ref I2S_DATA_SIZE_16BIT_COMPACT
+ * "16-bit compact" or \ref I2S_DATA_SIZE_8BIT_COMPACT "8-bit compact", with
+ * these option I2S Serializer will compact left channel data and right channel
+ * data together, the left channel data will take lower bytes and right channel
+ * data take higher bytes.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_loop Loop-back Mode
+ * The I2S can be configured to loop back the Transmitter to Receiver. In this
+ * mode Serializer's input will be connected to another Serializer's output
+ * internally.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_sleep Sleep Modes
+ * The I2S will continue to operate in any sleep mode, where the selected source
+ * clocks are running.
+ *
+ * \section asfdoc_sam0_i2s_special_considerations Special Considerations
+ *
+ * There is no special considerations for I2S module.

+ *
+ * \section asfdoc_sam0_system_pinmux_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_pinmux_module_overview Module Overview
+ *
+ * The SAM devices contain a number of General Purpose I/O pins, used to
+ * interface the user application logic and internal hardware peripherals to
+ * an external system. The Pin Multiplexer (PINMUX) driver provides a method
+ * of configuring the individual pin peripheral multiplexers to select
+ * alternate pin functions.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition
+ * <table>
+ *  <tr>
+ *    <th>Driver Feature Macro</th>
+ *    <th>Supported devices</th>
+ *  </tr>
+ *  <tr>
+ *    <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td>
+ *    <td>SAM L21, SAM C20/C21</td>
+ *  </tr>
+ * </table>
+ * \note The specific features are only available in the driver when the
+ * selected device supports those features.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
+ * SAM devices use two naming conventions for the I/O pins in the device; one
+ * physical and one logical. Each physical pin on a device package is assigned
+ * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
+ * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
+ * former is used to map physical pins to their physical internal device module
+ * counterparts, for simplicity the design of this driver uses the logical GPIO
+ * numbers instead.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
+ * SAM devices contain a peripheral MUX, which is individually controllable
+ * for each I/O pin of the device. The peripheral MUX allows you to select the
+ * function of a physical package pin - whether it will be controlled as a user
+ * controllable GPIO pin, or whether it will be connected internally to one of
+ * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
+ * configured in GPIO mode, other peripherals connected to the same pin will be
+ * disabled.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
+ * There are several special modes that can be selected on one or more I/O pins
+ * of the device, which alter the input and output characteristics of the pad.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
+ * The Drive Strength configures the strength of the output driver on the
+ * pad. Normally, there is a fixed current limit that each I/O pin can safely
+ * drive, however some I/O pads offer a higher drive mode which increases this
+ * limit for that I/O pin at the expense of an increased power consumption.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
+ * The Slew Rate configures the slew rate of the output driver, limiting the
+ * rate at which the pad output voltage can change with time.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
+ * The Input Sample Mode configures the input sampler buffer of the pad. By
+ * default, the input buffer is only sampled "on-demand", i.e. when the user
+ * application attempts to read from the input buffer. This mode is the most
+ * power efficient, but increases the latency of the input sample by two clock
+ * cycles of the port clock. To reduce latency, the input sampler can instead
+ * be configured to always sample the input buffer on each port clock cycle, at
+ * the expense of an increased power consumption.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_module_overview_physical Physical Connection
+ *
+ * \ref asfdoc_sam0_system_pinmux_intconnections "The diagram below" shows
+ * how this module is interconnected within the device:
+ *

+ *   pad    -> pinmux;
+ *   pinmux -> peripherals;
+ * }
+ * \enddot
+ *
+ * \section asfdoc_sam0_system_pinmux_special_considerations Special Considerations
+ *
+ * The SAM port pin input sampling mode is set in groups of four physical
+ * pins; setting the sampling mode of any pin in a sub-group of eight I/O pins
+ * will configure the sampling mode of the entire sub-group.
+ *
+ * High Drive Strength output driver mode is not available on all device pins -
+ * refer to your device specific datasheet.

+ *
+ *
+ * \section asfdoc_sam0_system_module_overview Module Overview
+ *
+ * The System driver provides a collection of interfaces between the user
+ * application logic, and the core device functionality (such as clocks, reset
+ * cause determination, etc.) that is required for all applications. It contains
+ * a number of sub-modules that control one specific aspect of the device:
+ *
+ * - System Core (this module)
+ * - \ref asfdoc_sam0_system_clock_group "System Clock Control" (sub-module)
+ * - \ref asfdoc_sam0_system_interrupt_group "System Interrupt Control" (sub-module)
+ * - \ref asfdoc_sam0_system_pinmux_group "System Pin Multiplexer Control" (sub-module)
+ *
+ *
+ * \if DEVICE_SAML21_SYSTEM_SUPPORT
+ * \subsection asfdoc_sam0_system_module_overview_vreg_l21 Voltage Regulator
+ * The SAM device controls the voltage regulators for the core (VDDCORE) and
+ * backup (VDDBU) domains. It sets the voltage regulators according to the sleep
+ * modes, the performance level, or the user configuration.
+ *
+ * In active mode, the voltage regulator can be chosen on the fly between a LDO
+ * or a Buck converter. In standby mode, the low power voltage regulator is used
+ * to supply VDDCORE.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_bbps Battery Backup Power Switch
+ * The SAM device supports connection of a battery backup to the VBAT power pin.
+ * It includes functionality that enables automatic power switching between main
+ * power and battery backup power. This will ensure power to the backup domain,
+ * when the main battery or power source is unavailable.
+ * \endif
+ *
+ * \if DEVICE_SAMC21_SYSTEM_SUPPORT
+ * \subsection asfdoc_sam0_system_module_overview_vreg_c21 Voltage Regulator
+ * The SAM device controls the voltage regulators for the core (VDDCORE). It sets
+ * the voltage regulators according to the sleep modes.
+ *
+ * There are a selectable reference voltage and voltage dependent on the temperature
+ * which can be used by analog modules like the ADC.
+ * \endif
+ *
+ * \subsection asfdoc_sam0_system_module_overview_vref Voltage References
+ * The various analog modules within the SAM devices (such as AC, ADC, and
+ * DAC) require a voltage reference to be configured to act as a reference point
+ * for comparisons and conversions.
+ *
+ * The SAM devices contain multiple references, including an internal
+ * temperature sensor and a fixed band-gap voltage source. When enabled, the
+ * associated voltage reference can be selected within the desired peripheral
+ * where applicable.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_reset_cause System Reset Cause
+ * In some applications there may be a need to execute a different program
+ * flow based on how the device was reset. For example, if the cause of reset
+ * was the Watchdog timer (WDT), this might indicate an error in the application,
+ * and a form of error handling or error logging might be needed.
+ *
+ * For this reason, an API is provided to retrieve the cause of the last system
+ * reset, so that appropriate action can be taken.
+ *
+ * \if DEVICE_SAML21_SYSTEM_SUPPORT
+ * There are three groups of reset sources:
+ *   - Power supply reset: Resets caused by an electrical issue. It covers POR and BOD reset.
+ *   - User reset: Resets caused by the application. It covers external reset,
+ *             system reset, and watchdog reset.
+ *   - Backup reset: Resets caused by a backup mode exit condition.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_performance_level Performance Level
+ * Performance level allows the user to adjust the regulator output voltage to reduce
+ * power consumption. The user can on the fly select the most suitable performance
+ * level, depending on the application demands.
+ *
+ * The SAM device can operate at two different performance levels (PL0 and PL2).
+ * When operating at PL0, the voltage applied on the full logic area is reduced
+ * by voltage scaling. This voltage scaling technique allows to reduce the active
+ * power consumption while decreasing the maximum frequency of the device. When
+ * operating at PL2, the voltage regulator supplies the highest voltage, allowing
+ * the device to run at higher clock speeds.
+ *
+ * Performance level transition is possible only when the device is in active
+ * mode. After a reset, the device starts at the lowest performance level
+ * (lowest power consumption and lowest max. frequency). The application can then
+ * switch to another performance level at any time without any stop in the code
+ * execution. As shown in \ref asfdoc_sam0_system_performance_level_transition_figure.
+ *
+ * \note When scaling down the performance level, the bus frequency should first be
+ *  scaled down in order to not exceed the maximum frequency allowed for the
+ *  low performance level.
+ *  When scaling up the performance level (e.g. from PL0 to PL2), check the performance
+ *  level status before increasing the bus frequency. It can be increased only
+ *  when the performance level transition is completed.
+ *
+ * \anchor asfdoc_sam0_system_performance_level_transition_figure
+ * \image html performance_level_transition.svg "Performance Level Transition"
+ *
+ * \subsection asfdoc_sam0_system_module_overview_power_domain Power Domain Gating
+ * Power domain gating allows power saving by reducing the voltage in logic
+ * areas in the device to a low-power supply. The feature is available in
+ * Standby sleep mode and will reduce the voltage in domains where all peripherals
+ * are idle. Internal logic will maintain its content, meaning the corresponding
+ * peripherals will not need to be reconfigured when normal operating voltage
+ * is returned. Most power domains can be in the following three states:
+ *
+ * - Active state: The power domain is powered on.
+ * - Retention state: The main voltage supply for the power domain is switched off,
+ * while maintaining a secondary low-power supply for the sequential cells. The
+ * logic context is restored when waking up.
+ * - Off state: The power domain is entirely powered off. The logic context is lost.
+ *
+ * The SAM L21 device  contains three power domains which can be controlled using
+ * power domain gating, namely PD0, PD1, and PD2. These power domains can be
+ * configured to the following cases:
+ * - Default with no sleepwalking peripherals: A power domain is automatically set
+ * to retention state in standby sleep mode if no activity require it. The application
+ * can force all power domains to remain in active state during standby sleep mode
+ * in order to accelerate wakeup time.
+ * - Default with sleepwalking peripherals: If one or more peripherals are enabled
+ * to perform sleepwalking tasks in standby sleep mode, the corresponding power
+ * domain (PDn) remains in active state as well as all inferior power domains (<PDn).
+ * - Sleepwalking with dynamic power domain gating: During standby sleep mode, a
+ * power domain (PDn) in active can wake up a superior power domain (>PDn) in order
+ * to perform a sleepwalking task. The superior power domain is then automatically
+ * set to active state. At the end of the sleepwalking task, the device can either
+ * be woken up or the superior power domain can return to retention state.
+ *
+ * Power domains can be linked to each other, it allows a power domain (PDn) to be kept
+ * in active state if the inferior power domain (PDn-1) is in active state too.
+ *
+ * \ref asfdoc_sam0_system_power_domain_overview_table illustrates the
+ * four cases to consider in standby mode.

+ * \section asfdoc_sam0_system_interrupt_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_interrupt_module_overview Module Overview
+ *
+ * The ARM&reg; Cortex&reg; M0+ core contains an interrupt and exception vector table, which
+ * can be used to configure the device's interrupt handlers; individual
+ * interrupts and exceptions can be enabled and disabled, as well as configured
+ * with a variable priority.
+ *
+ * This driver provides a set of wrappers around the core interrupt functions,
+ * to expose a simple API for the management of global and individual interrupts
+ * within the device.
+ *
+ * \subsection asfdoc_sam0_system_interrupt_module_overview_criticalsec Critical Sections
+ * In some applications it is important to ensure that no interrupts may be
+ * executed by the system whilst a critical portion of code is being run; for
+ * example, a buffer may be copied from one context to another - during which
+ * interrupts must be disabled to avoid corruption of the source buffer contents
+ * until the copy has completed. This driver provides a basic API to enter and
+ * exit nested critical sections, so that global interrupts can be kept disabled
+ * for as long as necessary to complete a critical application code section.
+ *
+ * \subsection asfdoc_sam0_system_interrupt_module_overview_softints Software Interrupts
+ * For some applications, it may be desirable to raise a module or core
+ * interrupt via software. For this reason, a set of APIs to set an interrupt or
+ * exception as pending are provided to the user application.
+ *
+ * \section asfdoc_sam0_system_interrupt_special_considerations Special Considerations
+ *
+ * Interrupts from peripherals in the SAM devices are on a per-module basis;
+ * an interrupt raised from any source within a module will cause a single,
+ * module-common handler to execute. It is the user application or driver's
+ * responsibility to de-multiplex the module-common interrupt to determine the
+ * exact interrupt cause.
+ *

+ *
+ * \section asfdoc_sam0_tc_module_overview Module Overview
+ *
+ * The Timer/Counter (TC) module provides a set of timing and counting related
+ * functionality, such as the generation of periodic waveforms, the capturing
+ * of a periodic waveform's frequency/duty cycle, and software timekeeping for
+ * periodic operations. TC modules can be configured to use an 8-, 16-, or
+ * 32-bit counter size.
+ *
+ * This TC module for the SAM is capable of the following functions:
+ *
+ * - Generation of PWM signals
+ * - Generation of timestamps for events
+ * - General time counting
+ * - Waveform period capture
+ * - Waveform frequency capture

+ *
+ * \subsection asfdoc_sam0_tc_module_overview_func_desc Functional Description
+ * Independent of the configured counter size, each TC module can be set up
+ * in one of two different modes; capture and compare.
+ *
+ * In capture mode, the counter value is stored when a configurable event
+ * occurs. This mode can be used to generate timestamps used in event capture,
+ * or it can be used for the measurement of a periodic input signal's
+ * frequency/duty cycle.
+ *
+ * In compare mode, the counter value is compared against one or more of the
+ * configured channel compare values. When the counter value coincides with a
+ * compare value an action can be taken automatically by the module, such as
+ * generating an output event or toggling a pin when used for frequency or PWM
+ * signal generation.
+ *
+ * \note The connection of events between modules requires the use of the
+ *       \ref asfdoc_sam0_events_group "SAM Event System Driver (EVENTS)"
+ *       to route output event of one module to the input event of another.
+ *       For more information on event routing, refer to the event driver
+ *       documentation.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_tc_size Timer/Counter Size
+ * Each timer module can be configured in one of three different counter
+ * sizes; 8-, 16-, and 32-bit. The size of the counter determines the maximum
+ * value it can count to before an overflow occurs and the count is reset back
+ * to zero. \ref asfdoc_sam0_tc_count_size_vs_top "The table below" shows the
+ * maximum values for each of the possible counter sizes.
+ *
+ * \anchor asfdoc_sam0_tc_count_size_vs_top
+ * <table>
+ *  <caption>Timer Counter Sizes and Their Maximum Count Values</caption>
+ *  <tr>
+ *    <th>Counter size</th>
+ *    <th>Max. (hexadecimal)</th>
+ *    <th>Max. (decimal)</th>
+ *  </tr>
+ *  <tr>
+ *    <td>8-bit</td>
+ *    <td>0xFF</td>
+ *    <td>255</td>
+ *  </tr>
+ *  <tr>
+ *    <td>16-bit</td>
+ *    <td>0xFFFF</td>
+ *    <td>65,535</td>
+ *  </tr>
+ *  <tr>
+ *    <td>32-bit</td>
+ *    <td>0xFFFFFFFF</td>
+ *    <td>4,294,967,295</td>
+ *  </tr>
+ * </table>
+ *
+ * When using the counter in 16- or 32-bit count mode, Compare Capture
+ * register 0 (CC0) is used to store the period value when running in PWM
+ * generation match mode.
+ *
+ * When using 32-bit counter size, two 16-bit counters are chained together
+ * in a cascade formation. Except in SAM D09/D10/D11, Even numbered TC modules
+ * (e.g. TC0, TC2) can be configured as 32-bit counters. The odd numbered
+ * counters will act as slaves to the even numbered masters, and will not
+ * be reconfigurable until the master timer is disabled. The pairing of timer
+ * modules for 32-bit mode is shown in \ref asfdoc_sam0_tc_module_ms_pairs
+ * "the table below".
+ *
+ * \anchor asfdoc_sam0_tc_module_ms_pairs
+ * <table>
+ *   <caption>TC Master and Slave Module Pairings</caption>
+ *   <tr>
+ *     <th>Master TC Module</th>
+ *     <th>Slave TC Module</th>

+ *   <tr>

+ *   </tr>
+ *   <tr>
+ *     <td>TCn-1</td>
+ *     <td>TCn</td>
+ *   </tr>
+ * </table>
+ *
+ * In SAM D09/D10/D11, odd numbered TC modules (e.g. TC1) can be configured as 32-bit
+ * counters. The even numbered(e.g. TC2) counters will act as slaves to the odd
+ * numbered masters.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_clock Clock Settings
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_selection Clock Selection
+ * Each TC peripheral is clocked asynchronously to the system clock by a GCLK
+ * (Generic Clock) channel. The GCLK channel connects to any of the GCLK
+ * generators. The GCLK generators are configured to use one of the available
+ * clock sources on the system such as internal oscillator, external crystals,
+ * etc. see the \ref asfdoc_sam0_system_clock_group "Generic Clock driver"
+ *for
+ * more information.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_prescaler Prescaler
+ * Each TC module in the SAM has its own individual clock prescaler, which
+ * can be used to divide the input clock frequency used in the counter. This
+ * prescaler only scales the clock used to provide clock pulses for the counter
+ * to count, and does not affect the digital register interface portion of
+ * the module, thus the timer registers will synchronize to the raw GCLK
+ * frequency input to the module.
+ *
+ * As a result of this, when selecting a GCLK frequency and timer prescaler
+ * value the user application should consider both the timer resolution
+ * required and the synchronization frequency, to avoid lengthy
+ * synchronization times of the module if a very slow GCLK frequency is fed
+ * into the TC module. It is preferable to use a higher module GCLK frequency
+ * as the input to the timer, and prescale this down as much as possible to
+ * obtain a suitable counter frequency in latency-sensitive applications.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_reloading Reloading
+ * Timer modules also contain a configurable reload action, used when a
+ * re-trigger event occurs. Examples of a re-trigger event are the counter
+ * reaching the maximum value when counting up, or when an event from the event
+ * system tells the counter to re-trigger. The reload action determines if the
+ * prescaler should be reset, and when this should happen. The counter will
+ * always be reloaded with the value it is set to start counting from. The user
+ * can choose between three different reload actions, described in
+ * \ref asfdoc_sam0_tc_module_reload_act "the table below".
+ *
+ * \anchor asfdoc_sam0_tc_module_reload_act
+ * <table>
+ *   <caption>TC Module Reload Actions</caption>
+ *   <tr>
+ *     <th>Reload action</th>
+ *     <th>Description</th>
+ *   </tr>
+ *   <tr>
+ *     <td>\ref TC_RELOAD_ACTION_GCLK </td>
+ *     <td>Reload TC counter value on next GCLK cycle. Leave prescaler
+ *         as-is.</td>
+ *   </tr>
+ *   <tr>
+ *     <td>\ref TC_RELOAD_ACTION_PRESC </td>
+ *     <td>Reloads TC counter value on next prescaler clock. Leave prescaler
+ *         as-is.</td>
+ *   </tr>
+ *  <tr>
+ *    <td> \ref TC_RELOAD_ACTION_RESYNC </td>
+ *    <td>Reload TC counter value on next GCLK cycle. Clear prescaler to
+ *        zero.</td>
+ *  </tr>
+ * </table>
+ *
+ * The reload action to use will depend on the specific application being
+ * implemented. One example is when an external trigger for a reload occurs; if
+ * the TC uses the prescaler, the counter in the prescaler should not have a
+ * value between zero and the division factor. The TC counter and the counter
+ * in the prescaler should both start at zero. When the counter is set to
+ * re-trigger when it reaches the maximum value on the other hand, this is not the
+ * right option to use. In such a case it would be better if the prescaler is
+ * left unaltered when the re-trigger happens, letting the counter reset on the
+ * next GCLK cycle.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_compare_match Compare Match Operations
+ * In compare match operation, Compare/Capture registers are used in comparison
+ * with the counter value. When the timer's count value matches the value of a
+ * compare channel, a user defined action can be taken.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_timer Basic Timer
+ *
+ * A Basic Timer is a simple application where compare match operations is used
+ * to determine when a specific period has elapsed. In Basic Timer operations,
+ * one or more values in the module's Compare/Capture registers are used to
+ * specify the time (as a number of prescaled GCLK cycles) when an action should
+ * be taken by the microcontroller. This can be an Interrupt Service Routine
+ * (ISR), event generator via the event system, or a software flag that is
+ * polled via the user application.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg Waveform Generation
+ *
+ * Waveform generation enables the TC module to generate square waves, or if
+ * combined with an external passive low-pass filter; analog waveforms.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_pwm Waveform Generation - PWM
+ *
+ * Pulse width modulation is a form of waveform generation and a signalling
+ * technique that can be useful in many situations. When PWM mode is used,
+ * a digital pulse train with a configurable frequency and duty cycle can be
+ * generated by the TC module and output to a GPIO pin of the device.
+ *
+ * Often PWM is used to communicate a control or information parameter to an
+ * external circuit or component. Differing impedances of the source generator
+ * and sink receiver circuits is less of an issue when using PWM compared to
+ * using an analog voltage value, as noise will not generally affect the
+ * signal's integrity to a meaningful extent.
+ *
+ * \ref asfdoc_sam0_tc_module_pwm_normal_diag "The figure below" illustrates
+ * operations and different states of the counter and its output when running
+ * the counter in PWM normal mode. As can be seen, the TOP value is unchanged
+ * and is set to MAX. The compare match value is changed at several points to
+ * illustrate the resulting waveform output changes. The PWM output is set to
+ * normal (i.e. non-inverted) output mode.

+ *
+ *
+ * In \ref asfdoc_sam0_tc_module_pwm_match_diag "the figure below", the
+ * counter is set to generate PWM in Match mode. The PWM output is inverted via
+ * the appropriate configuration option in the TC driver configuration
+ * structure. In this example, the counter value is changed once, but the
+ * compare match value is kept unchanged. As can be seen, it is possible to
+ * change the TOP value when running in PWM match mode.

+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_freq Waveform Generation - Frequency
+ *
+ * Frequency Generation mode is in many ways identical to PWM
+ * generation. However, in Frequency Generation a toggle only occurs
+ * on the output when a match on a capture channels occurs. When the
+ * match is made, the timer value is reset, resulting in a variable
+ * frequency square wave with a fixed 50% duty cycle.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt Capture Operations
+ *
+ * In capture operations, any event from the event system or a pin change can
+ * trigger a capture of the counter value. This captured counter value can be
+ * used as a timestamp for the event, or it can be used in frequency and pulse
+ * width capture.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_event_capture Capture Operations - Event
+ *
+ * Event capture is a simple use of the capture functionality,
+ * designed to create timestamps for specific events. When the TC
+ * module's input capture pin is externally toggled, the current timer
+ * count value is copied into a buffered register which can then be
+ * read out by the user application.
+ *
+ * Note that when performing any capture operation, there is a risk that the
+ * counter reaches its top value (MAX) when counting up, or the bottom value
+ * (zero) when counting down, before the capture event occurs. This can distort
+ * the result, making event timestamps to appear shorter than reality; the
+ * user application should check for timer overflow when reading a capture
+ * result in order to detect this situation and perform an appropriate
+ * adjustment.
+ *
+ * Before checking for a new capture, \ref TC_STATUS_COUNT_OVERFLOW
+ * should be checked. The response to an overflow error is left to the user
+ * application, however it may be necessary to clear both the capture overflow
+ * flag and the capture flag upon each capture reading.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_pwc Capture Operations - Pulse Width
+ *
+ * Pulse Width Capture mode makes it possible to measure the pulse width and
+ * period of PWM signals. This mode uses two capture channels of the counter.
+ * This means that the counter module used for Pulse Width Capture can not be
+ * used for any other purpose. There are two modes for pulse width capture;
+ * Pulse Width Period (PWP) and Period Pulse Width (PPW). In PWP mode, capture
+ * channel 0 is used for storing the pulse width and capture channel 1 stores
+ * the observed period. While in PPW mode, the roles of the two capture channels
+ * is reversed.
+ *
+ * As in the above example it is necessary to poll on interrupt flags to see
+ * if a new capture has happened and check that a capture overflow error has
+ * not occurred.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_oneshot One-shot Mode
+ *
+ * TC modules can be configured into a one-shot mode. When configured in this
+ * manner, starting the timer will cause it to count until the next overflow
+ * or underflow condition before automatically halting, waiting to be manually
+ * triggered by the user application software or an event signal from the event
+ * system.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_inversion Wave Generation Output Inversion
+ *
+ * The output of the wave generation can be inverted by hardware if desired,
+ * resulting in the logically inverted value being output to the configured
+ * device GPIO pin.
+ *
+ *
+ * \section asfdoc_sam0_tc_special_considerations Special Considerations
+ *
+ * The number of capture compare registers in each TC module is dependent on
+ * the specific SAM device being used, and in some cases the counter size.
+ *
+ * The maximum amount of capture compare registers available in any SAM
+ * device is two when running in 32-bit mode and four in 8- and 16-bit modes.

+ *
+ *
+ * \section asfdoc_sam0_wdt_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_wdt_module_overview Module Overview
+ *
+ * The Watchdog module (WDT) is designed to give an added level of safety in
+ * critical systems, to ensure a system reset is triggered in the case of a
+ * deadlock or other software malfunction that prevents normal device operation.
+ *
+ * At a basic level, the Watchdog is a system timer with a fixed period; once
+ * enabled, it will continue to count ticks of its asynchronous clock until
+ * it is periodically reset, or the timeout period is reached. In the event of a
+ * Watchdog timeout, the module will trigger a system reset identical to a pulse
+ * of the device's reset pin, resetting all peripherals to their power-on
+ * default states and restarting the application software from the reset vector.
+ *
+ * In many systems, there is an obvious upper bound to the amount of time each
+ * iteration of the main application loop can be expected to run, before a
+ * malfunction can be assumed (either due to a deadlock waiting on hardware or
+ * software, or due to other means). When the Watchdog is configured with a
+ * timeout period equal to this upper bound, a malfunction in the system will
+ * force a full system reset to allow for a graceful recovery.
+ *
+ * \subsection asfdoc_sam0_wdt_module_locked_mode Locked Mode
+ * The Watchdog configuration can be set in the device fuses and locked in
+ * hardware, so that no software changes can be made to the Watchdog
+ * configuration. Additionally, the Watchdog can be locked on in software if it
+ * is not already locked, so that the module configuration cannot be modified
+ * until a power on reset of the device.
+ *
+ * The locked configuration can be used to ensure that faulty software does not
+ * cause the Watchdog configuration to be changed, preserving the level of
+ * safety given by the module.
+ *
+ * \subsection asfdoc_sam0_wdt_module_window_mode Window Mode
+ * Just as there is a reasonable upper bound to the time the main program loop
+ * should take for each iteration, there is also in many applications a lower
+ * bound, i.e. a \a minimum time for which each loop iteration should run for
+ * under normal circumstances. To guard against a system failure resetting the
+ * Watchdog in a tight loop (or a failure in the system application causing the
+ * main loop to run faster than expected) a "Window" mode can be enabled to
+ * disallow resetting of the Watchdog counter before a certain period of time.
+ * If the Watchdog is not reset \a after the window opens but not \a before the
+ * Watchdog expires, the system will reset.
+ *
+ * \subsection asfdoc_sam0_wdt_module_early_warning Early Warning
+ * In some cases it is desirable to receive an early warning that the Watchdog is
+ * about to expire, so that some system action (such as saving any system
+ * configuration data for failure analysis purposes) can be performed before the
+ * system reset occurs. The Early Warning feature of the Watchdog module allows
+ * such a notification to be requested; after the configured early warning time
+ * (but before the expiry of the Watchdog counter) the Early Warning flag will
+ * become set, so that the user application can take an appropriate action.
+ *
+ * \note It is important to note that the purpose of the Early Warning feature
+ *       is \a not to allow the user application to reset the Watchdog; doing
+ *       so will defeat the safety the module gives to the user application.
+ *       Instead, this feature should be used purely to perform any tasks that
+ *       need to be undertaken before the system reset occurs.
+ *
+ * \subsection asfdoc_sam0_wdt_module_overview_physical Physical Connection
+ *
+ * \ref asfdoc_sam0_wdt_module_int_connections "The figure below" shows how
+ * this module is interconnected within the device.
+ *
+ * \anchor asfdoc_sam0_wdt_module_int_connections

+ *   wdt_module:f1 -> sys_reset;
+ * }
+ * \enddot
+ *
+ * \note Watchdog Counter of SAM L21/L22 is \a not provided by GCLK, but it uses an
+ *       internal 1KHz OSCULP32K output clock.
+ *
+ * \section asfdoc_sam0_wdt_special_considerations Special Considerations
+ *
+ * On some devices the Watchdog configuration can be fused to be always on in
+ * a particular configuration; if this mode is enabled the Watchdog is not
+ * software configurable and can have its count reset and early warning state
+ * checked/cleared only.

+# ArduinoHttpClient
+
+ArduinoHttpClient is a library to make it easier to interact with web servers from Arduino.
+
+Derived from [Adrian McEwen's HttpClient library](https://github.com/amcewen/HttpClient)
+
+## Dependencies
+
+- Requires a networking hardware and a library that provides transport specific `Client` instance, such as:
+  - [WiFi101](https://github.com/arduino-libraries/WiFi101)
+  - [Ethernet](https://github.com/arduino-libraries/Ethernet)
+  - [WiFi](https://github.com/arduino-libraries/WiFi)
+  - [GSM](https://github.com/arduino-libraries/GSM)
+
+## Usage
+
+In normal usage, handles the outgoing request and Host header.  The returned status code is parsed for you, as is the Content-Length header (if present).
+
+Because it expects an object of type Client, you can use it with any of the networking classes that derive from that.  Which means it will work with WiFiClient, EthernetClient and GSMClient.
+
+See the examples for more detail on how the library is used.

+Thank you for opening an issue on an Adafruit Arduino library repository.  To
+improve the speed of resolution please review the following guidelines and
+common troubleshooting steps below before creating the issue:
+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.
+You may delete the guideline and text above to just leave the following details:
+
+- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
+
+- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
+  VERSION HERE**
+
+- List the steps to reproduce the problem below (if possible attach a sketch or
+  copy the sketch code in too): **LIST REPRO STEPS BELOW**

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+Thank you for opening an issue on an Adafruit Arduino library repository.  To
+improve the speed of resolution please review the following guidelines and
+common troubleshooting steps below before creating the issue:
+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.
+You may delete the guideline and text above to just leave the following details:
+
+- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
+
+- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
+  VERSION HERE**
+
+- List the steps to reproduce the problem below (if possible attach a sketch or
+  copy the sketch code in too): **LIST REPRO STEPS BELOW**

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+This is a fork of JeeLab's fantastic real time clock library for Arduino.
+
+For details on using this library with an RTC module like the DS1307, PCF8523, or DS3231, see the guide at: https://learn.adafruit.com/ds1307-real-time-clock-breakout-board-kit/overview
+
+To download. click the DOWNLOADS button to the right, and rename the uncompressed folder RTClib.
+
+Place the RTClib folder in your *arduinosketchfolder*/libraries/ folder. 
+You may need to create the libraries subfolder if its your first library. Restart the IDE.
+
+Please note that dayOfTheWeek() ranges from 0 to 6 inclusive with 0 being 'Sunday'

+			  exceed 133 bytes (MAX_HIDDEN_SITES SSIDs x 32 bytes each, which is max SSID length).
+              For instance, encoding the two hidden SSIDs "DEMO_AP" and "TEST" 
+			  results in the following buffer content:

+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_clock_module_overview Module Overview
+ * The SAM devices contain a sophisticated clocking system, which is designed
+ * to give the maximum flexibility to the user application. This system allows
+ * a system designer to tune the performance and power consumption of the device
+ * in a dynamic manner, to achieve the best trade-off between the two for a
+ * particular application.
+ *
+ * This driver provides a set of functions for the configuration and management
+ * of the various clock related functionality within the device.

+ *	</tr>
+ * </table>
+ * \note The specific features are only available in the driver when the
+ * selected device supports those features.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_clock_sources Clock Sources
+ * The SAM devices have a number of master clock source modules, each of
+ * which being capable of producing a stabilized output frequency, which can then
+ * be fed into the various peripherals and modules within the device.
+ *
+ * Possible clock source modules include internal R/C oscillators, internal
+ * DFLL modules, as well as external crystal oscillators and/or clock inputs.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_cpu_clock CPU / Bus Clocks
+ * The CPU and AHB/APBx buses are clocked by the same physical clock source
+ * (referred in this module as the Main Clock), however the APBx buses may
+ * have additional prescaler division ratios set to give each peripheral bus a
+ * different clock speed.
+ *
+ * The general main clock tree for the CPU and associated buses is shown in
+ * \ref asfdoc_sam0_system_clock_module_clock_tree "the figure below".

+ * \subsection asfdoc_sam0_system_clock_module_overview_clock_masking Clock Masking
+ * To save power, the input clock to one or more peripherals on the AHB and APBx
+ * buses can be masked away - when masked, no clock is passed into the module.
+ * Disabling of clocks of unused modules will prevent all access to the masked
+ * module, but will reduce the overall device power consumption.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_gclk Generic Clocks
+ * Within the SAM devices there are a number of Generic Clocks; these are used to
+ * provide clocks to the various peripheral clock domains in the device in a
+ * standardized manner. One or more master source clocks can be selected as the
+ * input clock to a Generic Clock Generator, which can prescale down the input
+ * frequency to a slower rate for use in a peripheral.
+ *
+ * Additionally, a number of individually selectable Generic Clock Channels are
+ * provided, which multiplex and gate the various generator outputs for one or
+ * more peripherals within the device. This setup allows for a single common
+ * generator to feed one or more channels, which can then be enabled or disabled
+ * individually as required.

+ * }
+ * \enddot
+ *
+ * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_generators Generic Clock Generators
+ * Each Generic Clock generator within the device can source its input clock
+ * from one of the provided Source Clocks, and prescale the output for one or
+ * more Generic Clock Channels in a one-to-many relationship. The generators
+ * thus allow for several clocks to be generated of different frequencies,
+ * power usages, and accuracies, which can be turned on and off individually to
+ * disable the clocks to multiple peripherals as a group.
+ *
+ * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_channels Generic Clock Channels
+ * To connect a Generic Clock Generator to a peripheral within the
+ * device, a Generic Clock Channel is used. Each peripheral or
+ * peripheral group has an associated Generic Clock Channel, which serves as the
+ * clock input for the peripheral(s). To supply a clock to the peripheral
+ * module(s), the associated channel must be connected to a running Generic
+ * Clock Generator and the channel enabled.

+ *
+ * There are no prerequisites for this module.
+ *
+ * \section asfdoc_sam0_i2s_module_overview Module Overview
+ *
+ * The I2S provides bidirectional, synchronous, digital audio link with external
+ * audio devices through these signal pins:
+ *  - Serial Data (SDm)
+ *  - Frame Sync (FSn)
+ *  - Serial Clock (SCKn)
+ *  - Master Clock (MCKn)
+ *
+ * The I2S consists of 2 Clock Units and 2 Serializers, which can be separately
+ * configured and enabled, to provide varies functionalities as follow:
+ *  - Communicate to Audio CODECs as Master or Slave, or provides clock and
+ *    frame sync signals as Controller
+ *  - Communicate to DAC or ADC through dedicated I2S serial interface
+ *  - Communicate to multi-slot or multiple stereo DACs or ADCs, via
+ *    Time Division Multiplexed (TDM) format
+ *  - Reading mono or stereo MEMS microphones, using the Pulse Density
+ *    Modulation (PDM) interface
+ *
+ * The I2S supports compact stereo data word, where left channel data bits are
+ * in lower half and right channel data bits are in upper half. It reduces the
+ * number of data words for stereo audio data and the DMA bandwidth.
+ *
+ * In master mode, the frame is configured by number of slots and slot size, and
+ * allows range covering 16fs to 1024fs MCK, to provide oversampling clock to an
+ * external audio CODEC or digital signal processor (DSP).
+ *
+ * A block diagram of the I2S can be seen in
+ * \ref asfdoc_sam0_i2s_module_block_diagram "the figure below".
+ *
+ * \anchor asfdoc_sam0_i2s_module_block_diagram
+ * \image html i2s_blocks.svg "I2S Block Diagram"
+ *
+ * This driver for I2S module provides an interface to
+ *  - initialize and control I2S module
+ *  - configure and control the I2S Clock Unit and Serializer
+ *  - transmit/receive data through I2S Serializer
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_clocks Clocks
+ *
+ * To use I2S module, the I2S bus interface clock (clk_i2s) must be enabled via
+ * Power Manager.
+ *
+ * For each I2S Clock Unit, a generic clock (gclk_i2s_n) is connnected. When I2S
+ * works in master mode the generic clock is used. It should be prepared before
+ * clock unit is used. In master mode the input generic clock will be used as
+ * MCK for SCKn and FSn generation, in addition, the MCK could be devided and
+ * output to I2S MCKn pin, as oversampling clock to external audio device.
+ *
+ * The I2S Serializer uses clock and control signal from Clock Unit to handle
+ * transfer. Select different clock unit with different configurations allows
+ * the I2S to work as master or slave, to work on non-related clocks.
+ *
+ * When using the driver with ASF, enabling the register interface is normally
+ * done by the \c init function.
+ * The gclk source for the asynchronous domain is normally configured and set
+ * through the _configuration struct_ / _init_ function. 
+ * If gclk source != 0 is used, this source has to be configured and enabled
+ * through invoking the system_gclk driver function when needed, or modifying
+ * conf_clock.h to enable it at the beginning.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_frame Audio Frame Generation
+ *
+ * Audio sample data for all channels are sent in frames, one frame can consist
+ * 1 - 8 slots where each slot can be configured to a size 8-bit, 16-bit, 24-bit
+ * or 32-bit. The audio frame synch clock is generated by the I2S Clock unit in
+ * the master/controller mode. The frame rate (or frame sync frequency) is
+ * calculated as follow:
+ *
+ * FS = SCK / number_of_slots / number_of_bits_in_slot
+ *
+ * The serial clock (SCK) source is either an external source (slave mode) or
+ * generated by the I2S clock unit (controller or master mode) using the MCK as
+ * source.
+ *
+ * SCK = MCK / sck_div
+ * \note SCK generation division value is MCKDIV in register.
+ *
+ * MCK is either an external source or generated using the gclk input from a
+ * generic clock generator.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_mode Master, Controller and Slave modes
+ *
+ * The i2s module has three modes: master, controller and slave.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_mst Master
+ * In master mode the module will control the data flow on the i2s bus and can
+ * be responsible for clock generation. The Serializers are enabled and will
+ * transmit/receive data. On a bus with only master and slave the SCK and FS
+ * clock signal will be outputted on the SCK and FS pin on the master module.
+ * MCK can optionally be outputted on the MCK pin, if there is a controller
+ * module on the bus the SCK, FS and optionally the MCK clock is sourced from
+ * the same pins. Serial data will be trancieved on the SD pin in both
+ * scenarios.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_ctl Controller
+ * In controller mode the module will generate the clock signals, but the
+ * Serializers are disabled and no data will be transmitted/received by the
+ * module in this mode. The clock signals is outputted on the SCK, FS and
+ * optionally the MCK pin.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_slv Slave
+ * In slave mode the module will use the SCK and FS clock source from the master
+ * or the controller which is received on the SCK and FS pin. The MCK can
+ * optionally be sourced externally on the MCK pin. The Serializers are enabled
+ * and will tranceive data on the SD pin. All data flow is controlled by the
+ * master.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_chg Switch modes
+ * The mode switching between master, controller and slave modes are actually
+ * done by modifying the source mode of I2S pins.
+ * The source mode of I2S pins are selected by writing corresponding bits in
+ * CLKCTRLn.
+ * Since source mode switching changes the direction of pin, the mode must be
+ * changed when the I2S Clock Unit is stopped.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_data Data Stream Reception/Transmission
+ *
+ * The I2S module support several data stream formats:
+ * - I2S format
+ * - Time Division Multiplexed (TDM) format
+ * - Pulse Density Modulation (PDM) format (reception only)
+ *
+ * Basically the I2S module can send several words within each frame, it's more
+ * like TDM format. With adjust to the number of data words in a frame, the FS
+ * width, the FS to data bits delay, etc., the module is able to handle I2S
+ * compliant data stream.
+ *
+ * Also the Serializer can receive PDM format data stream, which allows the I2S
+ * module receive 1 PDM data on each SCK edge.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_i2s I2S Stream Reception/Transmission
+ *
+ * For 2-channel I2S compliant data stream format the i2s module uses the FS
+ * line as word select (WS) signal and will send left channel data word on low
+ * WS level and right channel data word on high WS level as specified in the I2S
+ * standard. The supported word sizes are 8-, 16-, 18-, 20-, 24- and 32- bit.
+ *
+ * Thus for I2S stream, the following settings should be applied to the module:
+ *  - Data starting delay after FS transition : one SCK period
+ *  - FS width : half of frame
+ *  - Data bits adjust in word : left-adjusted
+ *  - Bit transmitting order : MSB first
+ *
+ * Following is an example for I2S application connections and waveforms. See
+ * \ref asfdoc_sam0_i2s_module_i2s_example_diagram "the figure below".
+ *
+ * \anchor asfdoc_sam0_i2s_module_i2s_example_diagram
+ * \image html i2s_example.svg "I2S Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_tdm TDM Stream Reception/Transmission
+ * In TDM format, the module sends several data words in each frame. For this
+ * data stream format most of the configurations could be adjusted:
+ *  - Main Frame related settings are as follow:
+ *   - Frame Sync (FS) options:
+ *    - the active edge of the FS (or if FS is inverted before use)
+ *    - the width of the FS
+ *   - the delay between FS to first data bit
+ *  - Data alignment in slot
+ *  - The number of slots and slot size can be adjusted, it has been mentioned
+ *    in \ref asfdoc_sam0_i2s_module_overview_frame
+ *  - The data word size is controlled by Serializer, it can be chosen among
+ *    8, 16, 18, 20, 24 and 32 bits.
+ *
+ * The general TDM waveform generation is as follow:
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_wave_diagram
+ * \image html tdm_wave.svg "TDM Waveform generation"
+ *
+ * Some other settings could also be found to set up clock, data formatting and
+ * pin mux.
+ * refer to \ref i2s_clock_unit_config "Clock Unit Configurations"
+ * and \ref i2s_serializer_config "Serializer Configurations" for more
+ * details.
+ *
+ * Following is examples for different application use cases.
+ *
+ * See \ref asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram "here" for
+ * the Time Slot Application connection and waveform example.
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram
+ * \image html tdm_timeslot_example.svg "Codec Example Diagram"
+ *
+ * See \ref asfdoc_sam0_i2s_module_tdm_codec_example_diagram "here" for the
+ * Codec Application connection and waveform example.
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_codec_example_diagram
+ * \image html tdm_codec_example.svg "Time Slot Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_pdm PDM Reception
+ * The I2S Serializer integrates PDM reception feature, to use this feature,
+ * simply select PDM2 mode in Serializer configuration. In PDM2 mode, it assumes
+ * two microphones are input for stereo stream. The left microphone bits will
+ * be stored in lower half and right microphone bits in upper half of the data
+ * word, like in compact stereo format.
+ *
+ * See \ref asfdoc_sam0_i2s_module_pdm_example_diagram "following figure" for an
+ * example of PDM Microphones Application with both left and right channel
+ * microphone connected.
+ *
+ * \anchor asfdoc_sam0_i2s_module_pdm_example_diagram
+ * \image html pdm_example.svg "Time PDM2 Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_fmt MONO and Compact Data
+ * The I2S Serializer can accept some pre-defined data format and generates
+ * the data stream in specified way.
+ *
+ * When transmitting data, the Serializer can work in MONO mode: assum input
+ * is single channel mono data on left channel and copy it to right channel
+ * automatically.
+ *
+ * Also the I2S Serializer can support compact stereo data word. The data word
+ * size of the Serializer can be set to \ref I2S_DATA_SIZE_16BIT_COMPACT
+ * "16-bit compact" or \ref I2S_DATA_SIZE_8BIT_COMPACT "8-bit compact", with
+ * these option I2S Serializer will compact left channel data and right channel
+ * data together, the left channel data will take lower bytes and right channel
+ * data take higher bytes.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_loop Loop-back Mode
+ * The I2S can be configured to loop back the Transmitter to Receiver. In this
+ * mode Serializer's input will be connected to another Serializer's output
+ * internally.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_sleep Sleep Modes
+ * The I2S will continue to operate in any sleep mode, where the selected source
+ * clocks are running.
+ *
+ * \section asfdoc_sam0_i2s_special_considerations Special Considerations
+ *
+ * There is no special considerations for I2S module.
+ *
+ * \section asfdoc_sam0_i2s_extra_info Extra Information

+ *  - Atmel | SMART SAM C20/C21
+ *
+ * Physically, the modules are interconnected within the device as shown in the
+ * following diagram:
+ *
+ * The outline of this documentation is as follows:

+ *  - \ref asfdoc_sam0_system_pinmux_module_overview

+ *
+ * \section asfdoc_sam0_system_pinmux_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_pinmux_module_overview Module Overview
+ *
+ * The SAM devices contain a number of General Purpose I/O pins, used to
+ * interface the user application logic and internal hardware peripherals to
+ * an external system. The Pin Multiplexer (PINMUX) driver provides a method
+ * of configuring the individual pin peripheral multiplexers to select
+ * alternate pin functions.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition
+ * <table>
+ *  <tr>
+ *    <th>Driver Feature Macro</th>
+ *    <th>Supported devices</th>
+ *  </tr>
+ *  <tr>
+ *    <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td>
+ *    <td>SAM L21, SAM C20/C21</td>
+ *  </tr>
+ * </table>
+ * \note The specific features are only available in the driver when the
+ * selected device supports those features.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
+ * SAM devices use two naming conventions for the I/O pins in the device; one
+ * physical and one logical. Each physical pin on a device package is assigned
+ * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
+ * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
+ * former is used to map physical pins to their physical internal device module
+ * counterparts, for simplicity the design of this driver uses the logical GPIO
+ * numbers instead.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
+ * SAM devices contain a peripheral MUX, which is individually controllable
+ * for each I/O pin of the device. The peripheral MUX allows you to select the
+ * function of a physical package pin - whether it will be controlled as a user
+ * controllable GPIO pin, or whether it will be connected internally to one of
+ * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
+ * configured in GPIO mode, other peripherals connected to the same pin will be
+ * disabled.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
+ * There are several special modes that can be selected on one or more I/O pins
+ * of the device, which alter the input and output characteristics of the pad.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
+ * The Drive Strength configures the strength of the output driver on the
+ * pad. Normally, there is a fixed current limit that each I/O pin can safely
+ * drive, however some I/O pads offer a higher drive mode which increases this
+ * limit for that I/O pin at the expense of an increased power consumption.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
+ * The Slew Rate configures the slew rate of the output driver, limiting the
+ * rate at which the pad output voltage can change with time.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
+ * The Input Sample Mode configures the input sampler buffer of the pad. By
+ * default, the input buffer is only sampled "on-demand", i.e. when the user
+ * application attempts to read from the input buffer. This mode is the most
+ * power efficient, but increases the latency of the input sample by two clock
+ * cycles of the port clock. To reduce latency, the input sampler can instead
+ * be configured to always sample the input buffer on each port clock cycle, at
+ * the expense of an increased power consumption.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_module_overview_physical Physical Connection
+ *
+ * \ref asfdoc_sam0_system_pinmux_intconnections "The diagram below" shows
+ * how this module is interconnected within the device:
+ *
+ * \anchor asfdoc_sam0_system_pinmux_intconnections

+ *   pad    -> pinmux;
+ *   pinmux -> peripherals;
+ * }
+ * \enddot
+ *
+ * \section asfdoc_sam0_system_pinmux_special_considerations Special Considerations
+ *
+ * The SAM port pin input sampling mode is set in groups of four physical
+ * pins; setting the sampling mode of any pin in a sub-group of eight I/O pins
+ * will configure the sampling mode of the entire sub-group.
+ *
+ * High Drive Strength output driver mode is not available on all device pins -
+ * refer to your device specific datasheet.

+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_module_overview Module Overview
+ *
+ * The System driver provides a collection of interfaces between the user
+ * application logic, and the core device functionality (such as clocks, reset
+ * cause determination, etc.) that is required for all applications. It contains
+ * a number of sub-modules that control one specific aspect of the device:
+ *
+ * - System Core (this module)
+ * - \ref asfdoc_sam0_system_clock_group "System Clock Control" (sub-module)
+ * - \ref asfdoc_sam0_system_interrupt_group "System Interrupt Control" (sub-module)
+ * - \ref asfdoc_sam0_system_pinmux_group "System Pin Multiplexer Control" (sub-module)
+ *
+ *
+ * \if DEVICE_SAML21_SYSTEM_SUPPORT
+ * \subsection asfdoc_sam0_system_module_overview_vreg_l21 Voltage Regulator
+ * The SAM device controls the voltage regulators for the core (VDDCORE) and
+ * backup (VDDBU) domains. It sets the voltage regulators according to the sleep
+ * modes, the performance level, or the user configuration.
+ *
+ * In active mode, the voltage regulator can be chosen on the fly between a LDO
+ * or a Buck converter. In standby mode, the low power voltage regulator is used
+ * to supply VDDCORE.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_bbps Battery Backup Power Switch
+ * The SAM device supports connection of a battery backup to the VBAT power pin.
+ * It includes functionality that enables automatic power switching between main
+ * power and battery backup power. This will ensure power to the backup domain,
+ * when the main battery or power source is unavailable.
+ * \endif
+ *
+ * \if DEVICE_SAMC21_SYSTEM_SUPPORT
+ * \subsection asfdoc_sam0_system_module_overview_vreg_c21 Voltage Regulator
+ * The SAM device controls the voltage regulators for the core (VDDCORE). It sets
+ * the voltage regulators according to the sleep modes.
+ *
+ * There are a selectable reference voltage and voltage dependent on the temperature
+ * which can be used by analog modules like the ADC.
+ * \endif
+ *
+ * \subsection asfdoc_sam0_system_module_overview_vref Voltage References
+ * The various analog modules within the SAM devices (such as AC, ADC, and
+ * DAC) require a voltage reference to be configured to act as a reference point
+ * for comparisons and conversions.
+ *
+ * The SAM devices contain multiple references, including an internal
+ * temperature sensor and a fixed band-gap voltage source. When enabled, the
+ * associated voltage reference can be selected within the desired peripheral
+ * where applicable.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_reset_cause System Reset Cause
+ * In some applications there may be a need to execute a different program
+ * flow based on how the device was reset. For example, if the cause of reset
+ * was the Watchdog timer (WDT), this might indicate an error in the application,
+ * and a form of error handling or error logging might be needed.
+ *
+ * For this reason, an API is provided to retrieve the cause of the last system
+ * reset, so that appropriate action can be taken.
+ *
+ * \if DEVICE_SAML21_SYSTEM_SUPPORT
+ * There are three groups of reset sources:
+ *   - Power supply reset: Resets caused by an electrical issue. It covers POR and BOD reset.
+ *   - User reset: Resets caused by the application. It covers external reset,
+ *             system reset, and watchdog reset.
+ *   - Backup reset: Resets caused by a backup mode exit condition.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_performance_level Performance Level
+ * Performance level allows the user to adjust the regulator output voltage to reduce
+ * power consumption. The user can on the fly select the most suitable performance
+ * level, depending on the application demands.
+ *
+ * The SAM device can operate at two different performance levels (PL0 and PL2).
+ * When operating at PL0, the voltage applied on the full logic area is reduced
+ * by voltage scaling. This voltage scaling technique allows to reduce the active
+ * power consumption while decreasing the maximum frequency of the device. When
+ * operating at PL2, the voltage regulator supplies the highest voltage, allowing
+ * the device to run at higher clock speeds.
+ *
+ * Performance level transition is possible only when the device is in active
+ * mode. After a reset, the device starts at the lowest performance level
+ * (lowest power consumption and lowest max. frequency). The application can then
+ * switch to another performance level at any time without any stop in the code
+ * execution. As shown in \ref asfdoc_sam0_system_performance_level_transition_figure.
+ *
+ * \note When scaling down the performance level, the bus frequency should first be
+ *  scaled down in order to not exceed the maximum frequency allowed for the
+ *  low performance level.
+ *  When scaling up the performance level (e.g. from PL0 to PL2), check the performance
+ *  level status before increasing the bus frequency. It can be increased only
+ *  when the performance level transition is completed.
+ *
+ * \anchor asfdoc_sam0_system_performance_level_transition_figure
+ * \image html performance_level_transition.svg "Performance Level Transition"
+ *
+ * \subsection asfdoc_sam0_system_module_overview_power_domain Power Domain Gating
+ * Power domain gating allows power saving by reducing the voltage in logic
+ * areas in the device to a low-power supply. The feature is available in
+ * Standby sleep mode and will reduce the voltage in domains where all peripherals
+ * are idle. Internal logic will maintain its content, meaning the corresponding
+ * peripherals will not need to be reconfigured when normal operating voltage
+ * is returned. Most power domains can be in the following three states:
+ *
+ * - Active state: The power domain is powered on.
+ * - Retention state: The main voltage supply for the power domain is switched off,
+ * while maintaining a secondary low-power supply for the sequential cells. The
+ * logic context is restored when waking up.
+ * - Off state: The power domain is entirely powered off. The logic context is lost.
+ *
+ * The SAM L21 device  contains three power domains which can be controlled using
+ * power domain gating, namely PD0, PD1, and PD2. These power domains can be
+ * configured to the following cases:
+ * - Default with no sleepwalking peripherals: A power domain is automatically set
+ * to retention state in standby sleep mode if no activity require it. The application
+ * can force all power domains to remain in active state during standby sleep mode
+ * in order to accelerate wakeup time.
+ * - Default with sleepwalking peripherals: If one or more peripherals are enabled
+ * to perform sleepwalking tasks in standby sleep mode, the corresponding power
+ * domain (PDn) remains in active state as well as all inferior power domains (<PDn).
+ * - Sleepwalking with dynamic power domain gating: During standby sleep mode, a
+ * power domain (PDn) in active can wake up a superior power domain (>PDn) in order
+ * to perform a sleepwalking task. The superior power domain is then automatically
+ * set to active state. At the end of the sleepwalking task, the device can either
+ * be woken up or the superior power domain can return to retention state.
+ *
+ * Power domains can be linked to each other, it allows a power domain (PDn) to be kept
+ * in active state if the inferior power domain (PDn-1) is in active state too.
+ *
+ * \ref asfdoc_sam0_system_power_domain_overview_table illustrates the
+ * four cases to consider in standby mode.

+ *  - \ref asfdoc_sam0_system_interrupt_api_overview
+ *
+ *
+ * \section asfdoc_sam0_system_interrupt_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_interrupt_module_overview Module Overview
+ *
+ * The ARM&reg; Cortex&reg; M0+ core contains an interrupt and exception vector table, which
+ * can be used to configure the device's interrupt handlers; individual
+ * interrupts and exceptions can be enabled and disabled, as well as configured
+ * with a variable priority.
+ *
+ * This driver provides a set of wrappers around the core interrupt functions,
+ * to expose a simple API for the management of global and individual interrupts
+ * within the device.
+ *
+ * \subsection asfdoc_sam0_system_interrupt_module_overview_criticalsec Critical Sections
+ * In some applications it is important to ensure that no interrupts may be
+ * executed by the system whilst a critical portion of code is being run; for
+ * example, a buffer may be copied from one context to another - during which
+ * interrupts must be disabled to avoid corruption of the source buffer contents
+ * until the copy has completed. This driver provides a basic API to enter and
+ * exit nested critical sections, so that global interrupts can be kept disabled
+ * for as long as necessary to complete a critical application code section.
+ *
+ * \subsection asfdoc_sam0_system_interrupt_module_overview_softints Software Interrupts
+ * For some applications, it may be desirable to raise a module or core
+ * interrupt via software. For this reason, a set of APIs to set an interrupt or
+ * exception as pending are provided to the user application.
+ *
+ * \section asfdoc_sam0_system_interrupt_special_considerations Special Considerations
+ *
+ * Interrupts from peripherals in the SAM devices are on a per-module basis;
+ * an interrupt raised from any source within a module will cause a single,
+ * module-common handler to execute. It is the user application or driver's
+ * responsibility to de-multiplex the module-common interrupt to determine the
+ * exact interrupt cause.
+ *
+ * \section asfdoc_sam0_system_interrupt_extra_info Extra Information
+ *
+ * For extra information, see \ref asfdoc_sam0_system_interrupt_extra. This includes:
+ *  - \ref asfdoc_sam0_system_interrupt_extra_acronyms
+ *  - \ref asfdoc_sam0_system_interrupt_extra_dependencies

+ *  - \ref asfdoc_sam0_system_interrupt_extra_history

+ *
+ * \section asfdoc_sam0_tc_module_overview Module Overview
+ *
+ * The Timer/Counter (TC) module provides a set of timing and counting related
+ * functionality, such as the generation of periodic waveforms, the capturing
+ * of a periodic waveform's frequency/duty cycle, and software timekeeping for
+ * periodic operations. TC modules can be configured to use an 8-, 16-, or
+ * 32-bit counter size.
+ *
+ * This TC module for the SAM is capable of the following functions:
+ *
+ * - Generation of PWM signals
+ * - Generation of timestamps for events
+ * - General time counting
+ * - Waveform period capture
+ * - Waveform frequency capture

+ *
+ * \subsection asfdoc_sam0_tc_module_overview_func_desc Functional Description
+ * Independent of the configured counter size, each TC module can be set up
+ * in one of two different modes; capture and compare.
+ *
+ * In capture mode, the counter value is stored when a configurable event
+ * occurs. This mode can be used to generate timestamps used in event capture,
+ * or it can be used for the measurement of a periodic input signal's
+ * frequency/duty cycle.
+ *
+ * In compare mode, the counter value is compared against one or more of the
+ * configured channel compare values. When the counter value coincides with a
+ * compare value an action can be taken automatically by the module, such as
+ * generating an output event or toggling a pin when used for frequency or PWM
+ * signal generation.
+ *
+ * \note The connection of events between modules requires the use of the
+ *       \ref asfdoc_sam0_events_group "SAM Event System Driver (EVENTS)"
+ *       to route output event of one module to the input event of another.
+ *       For more information on event routing, refer to the event driver
+ *       documentation.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_tc_size Timer/Counter Size
+ * Each timer module can be configured in one of three different counter
+ * sizes; 8-, 16-, and 32-bit. The size of the counter determines the maximum
+ * value it can count to before an overflow occurs and the count is reset back
+ * to zero. \ref asfdoc_sam0_tc_count_size_vs_top "The table below" shows the
+ * maximum values for each of the possible counter sizes.
+ *
+ * \anchor asfdoc_sam0_tc_count_size_vs_top
+ * <table>
+ *  <caption>Timer Counter Sizes and Their Maximum Count Values</caption>
+ *  <tr>
+ *    <th>Counter size</th>
+ *    <th>Max. (hexadecimal)</th>
+ *    <th>Max. (decimal)</th>
+ *  </tr>
+ *  <tr>
+ *    <td>8-bit</td>
+ *    <td>0xFF</td>
+ *    <td>255</td>
+ *  </tr>
+ *  <tr>
+ *    <td>16-bit</td>
+ *    <td>0xFFFF</td>
+ *    <td>65,535</td>
+ *  </tr>
+ *  <tr>
+ *    <td>32-bit</td>
+ *    <td>0xFFFFFFFF</td>
+ *    <td>4,294,967,295</td>
+ *  </tr>
+ * </table>
+ *
+ * When using the counter in 16- or 32-bit count mode, Compare Capture
+ * register 0 (CC0) is used to store the period value when running in PWM
+ * generation match mode.
+ *
+ * When using 32-bit counter size, two 16-bit counters are chained together
+ * in a cascade formation. Except in SAM D09/D10/D11, Even numbered TC modules
+ * (e.g. TC0, TC2) can be configured as 32-bit counters. The odd numbered
+ * counters will act as slaves to the even numbered masters, and will not
+ * be reconfigurable until the master timer is disabled. The pairing of timer
+ * modules for 32-bit mode is shown in \ref asfdoc_sam0_tc_module_ms_pairs
+ * "the table below".
+ *
+ * \anchor asfdoc_sam0_tc_module_ms_pairs
+ * <table>
+ *   <caption>TC Master and Slave Module Pairings</caption>
+ *   <tr>
+ *     <th>Master TC Module</th>
+ *     <th>Slave TC Module</th>
+ *   </tr>
+ *   <tr>
+ *     <td>TC0</td>
+ *     <td>TC1</td>
+ *   </tr>
+ *   <tr>

+ *   </tr>
+ *   <tr>
+ *     <td>TCn-1</td>
+ *     <td>TCn</td>
+ *   </tr>
+ * </table>
+ *
+ * In SAM D09/D10/D11, odd numbered TC modules (e.g. TC1) can be configured as 32-bit
+ * counters. The even numbered(e.g. TC2) counters will act as slaves to the odd
+ * numbered masters.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_clock Clock Settings
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_selection Clock Selection
+ * Each TC peripheral is clocked asynchronously to the system clock by a GCLK
+ * (Generic Clock) channel. The GCLK channel connects to any of the GCLK
+ * generators. The GCLK generators are configured to use one of the available
+ * clock sources on the system such as internal oscillator, external crystals,
+ * etc. see the \ref asfdoc_sam0_system_clock_group "Generic Clock driver"
+ *for
+ * more information.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_prescaler Prescaler
+ * Each TC module in the SAM has its own individual clock prescaler, which
+ * can be used to divide the input clock frequency used in the counter. This
+ * prescaler only scales the clock used to provide clock pulses for the counter
+ * to count, and does not affect the digital register interface portion of
+ * the module, thus the timer registers will synchronize to the raw GCLK
+ * frequency input to the module.
+ *
+ * As a result of this, when selecting a GCLK frequency and timer prescaler
+ * value the user application should consider both the timer resolution
+ * required and the synchronization frequency, to avoid lengthy
+ * synchronization times of the module if a very slow GCLK frequency is fed
+ * into the TC module. It is preferable to use a higher module GCLK frequency
+ * as the input to the timer, and prescale this down as much as possible to
+ * obtain a suitable counter frequency in latency-sensitive applications.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_reloading Reloading
+ * Timer modules also contain a configurable reload action, used when a
+ * re-trigger event occurs. Examples of a re-trigger event are the counter
+ * reaching the maximum value when counting up, or when an event from the event
+ * system tells the counter to re-trigger. The reload action determines if the
+ * prescaler should be reset, and when this should happen. The counter will
+ * always be reloaded with the value it is set to start counting from. The user
+ * can choose between three different reload actions, described in
+ * \ref asfdoc_sam0_tc_module_reload_act "the table below".
+ *
+ * \anchor asfdoc_sam0_tc_module_reload_act
+ * <table>
+ *   <caption>TC Module Reload Actions</caption>
+ *   <tr>
+ *     <th>Reload action</th>
+ *     <th>Description</th>
+ *   </tr>
+ *   <tr>
+ *     <td>\ref TC_RELOAD_ACTION_GCLK </td>
+ *     <td>Reload TC counter value on next GCLK cycle. Leave prescaler
+ *         as-is.</td>
+ *   </tr>
+ *   <tr>
+ *     <td>\ref TC_RELOAD_ACTION_PRESC </td>
+ *     <td>Reloads TC counter value on next prescaler clock. Leave prescaler
+ *         as-is.</td>
+ *   </tr>
+ *  <tr>
+ *    <td> \ref TC_RELOAD_ACTION_RESYNC </td>
+ *    <td>Reload TC counter value on next GCLK cycle. Clear prescaler to
+ *        zero.</td>
+ *  </tr>
+ * </table>
+ *
+ * The reload action to use will depend on the specific application being
+ * implemented. One example is when an external trigger for a reload occurs; if
+ * the TC uses the prescaler, the counter in the prescaler should not have a
+ * value between zero and the division factor. The TC counter and the counter
+ * in the prescaler should both start at zero. When the counter is set to
+ * re-trigger when it reaches the maximum value on the other hand, this is not the
+ * right option to use. In such a case it would be better if the prescaler is
+ * left unaltered when the re-trigger happens, letting the counter reset on the
+ * next GCLK cycle.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_compare_match Compare Match Operations
+ * In compare match operation, Compare/Capture registers are used in comparison
+ * with the counter value. When the timer's count value matches the value of a
+ * compare channel, a user defined action can be taken.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_timer Basic Timer
+ *
+ * A Basic Timer is a simple application where compare match operations is used
+ * to determine when a specific period has elapsed. In Basic Timer operations,
+ * one or more values in the module's Compare/Capture registers are used to
+ * specify the time (as a number of prescaled GCLK cycles) when an action should
+ * be taken by the microcontroller. This can be an Interrupt Service Routine
+ * (ISR), event generator via the event system, or a software flag that is
+ * polled via the user application.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg Waveform Generation
+ *
+ * Waveform generation enables the TC module to generate square waves, or if
+ * combined with an external passive low-pass filter; analog waveforms.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_pwm Waveform Generation - PWM
+ *
+ * Pulse width modulation is a form of waveform generation and a signalling
+ * technique that can be useful in many situations. When PWM mode is used,
+ * a digital pulse train with a configurable frequency and duty cycle can be
+ * generated by the TC module and output to a GPIO pin of the device.
+ *
+ * Often PWM is used to communicate a control or information parameter to an
+ * external circuit or component. Differing impedances of the source generator
+ * and sink receiver circuits is less of an issue when using PWM compared to
+ * using an analog voltage value, as noise will not generally affect the
+ * signal's integrity to a meaningful extent.
+ *
+ * \ref asfdoc_sam0_tc_module_pwm_normal_diag "The figure below" illustrates
+ * operations and different states of the counter and its output when running
+ * the counter in PWM normal mode. As can be seen, the TOP value is unchanged
+ * and is set to MAX. The compare match value is changed at several points to
+ * illustrate the resulting waveform output changes. The PWM output is set to
+ * normal (i.e. non-inverted) output mode.
+ *
+ * \anchor asfdoc_sam0_tc_module_pwm_normal_diag
+ * \image html pwm_normal_ex.svg "Example of PWM in Normal Mode, and Different Counter Operations"
+ *
+ *
+ * In \ref asfdoc_sam0_tc_module_pwm_match_diag "the figure below", the
+ * counter is set to generate PWM in Match mode. The PWM output is inverted via
+ * the appropriate configuration option in the TC driver configuration
+ * structure. In this example, the counter value is changed once, but the
+ * compare match value is kept unchanged. As can be seen, it is possible to
+ * change the TOP value when running in PWM match mode.
+ *
+ * \anchor asfdoc_sam0_tc_module_pwm_match_diag
+ * \image html pwm_match_ex.svg "Example of PWM in Match Mode, and Different Counter Operations"
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_freq Waveform Generation - Frequency
+ *
+ * Frequency Generation mode is in many ways identical to PWM
+ * generation. However, in Frequency Generation a toggle only occurs
+ * on the output when a match on a capture channels occurs. When the
+ * match is made, the timer value is reset, resulting in a variable
+ * frequency square wave with a fixed 50% duty cycle.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt Capture Operations
+ *
+ * In capture operations, any event from the event system or a pin change can
+ * trigger a capture of the counter value. This captured counter value can be
+ * used as a timestamp for the event, or it can be used in frequency and pulse
+ * width capture.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_event_capture Capture Operations - Event
+ *
+ * Event capture is a simple use of the capture functionality,
+ * designed to create timestamps for specific events. When the TC
+ * module's input capture pin is externally toggled, the current timer
+ * count value is copied into a buffered register which can then be
+ * read out by the user application.
+ *
+ * Note that when performing any capture operation, there is a risk that the
+ * counter reaches its top value (MAX) when counting up, or the bottom value
+ * (zero) when counting down, before the capture event occurs. This can distort
+ * the result, making event timestamps to appear shorter than reality; the
+ * user application should check for timer overflow when reading a capture
+ * result in order to detect this situation and perform an appropriate
+ * adjustment.
+ *
+ * Before checking for a new capture, \ref TC_STATUS_COUNT_OVERFLOW
+ * should be checked. The response to an overflow error is left to the user
+ * application, however it may be necessary to clear both the capture overflow
+ * flag and the capture flag upon each capture reading.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_pwc Capture Operations - Pulse Width
+ *
+ * Pulse Width Capture mode makes it possible to measure the pulse width and
+ * period of PWM signals. This mode uses two capture channels of the counter.
+ * This means that the counter module used for Pulse Width Capture can not be
+ * used for any other purpose. There are two modes for pulse width capture;
+ * Pulse Width Period (PWP) and Period Pulse Width (PPW). In PWP mode, capture
+ * channel 0 is used for storing the pulse width and capture channel 1 stores
+ * the observed period. While in PPW mode, the roles of the two capture channels
+ * is reversed.
+ *
+ * As in the above example it is necessary to poll on interrupt flags to see
+ * if a new capture has happened and check that a capture overflow error has
+ * not occurred.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_oneshot One-shot Mode
+ *
+ * TC modules can be configured into a one-shot mode. When configured in this
+ * manner, starting the timer will cause it to count until the next overflow
+ * or underflow condition before automatically halting, waiting to be manually
+ * triggered by the user application software or an event signal from the event
+ * system.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_inversion Wave Generation Output Inversion
+ *
+ * The output of the wave generation can be inverted by hardware if desired,
+ * resulting in the logically inverted value being output to the configured
+ * device GPIO pin.
+ *
+ *
+ * \section asfdoc_sam0_tc_special_considerations Special Considerations
+ *
+ * The number of capture compare registers in each TC module is dependent on
+ * the specific SAM device being used, and in some cases the counter size.
+ *
+ * The maximum amount of capture compare registers available in any SAM
+ * device is two when running in 32-bit mode and four in 8- and 16-bit modes.

+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_wdt_module_overview Module Overview
+ *
+ * The Watchdog module (WDT) is designed to give an added level of safety in
+ * critical systems, to ensure a system reset is triggered in the case of a
+ * deadlock or other software malfunction that prevents normal device operation.
+ *
+ * At a basic level, the Watchdog is a system timer with a fixed period; once
+ * enabled, it will continue to count ticks of its asynchronous clock until
+ * it is periodically reset, or the timeout period is reached. In the event of a
+ * Watchdog timeout, the module will trigger a system reset identical to a pulse
+ * of the device's reset pin, resetting all peripherals to their power-on
+ * default states and restarting the application software from the reset vector.
+ *
+ * In many systems, there is an obvious upper bound to the amount of time each
+ * iteration of the main application loop can be expected to run, before a
+ * malfunction can be assumed (either due to a deadlock waiting on hardware or
+ * software, or due to other means). When the Watchdog is configured with a
+ * timeout period equal to this upper bound, a malfunction in the system will
+ * force a full system reset to allow for a graceful recovery.
+ *
+ * \subsection asfdoc_sam0_wdt_module_locked_mode Locked Mode
+ * The Watchdog configuration can be set in the device fuses and locked in
+ * hardware, so that no software changes can be made to the Watchdog
+ * configuration. Additionally, the Watchdog can be locked on in software if it
+ * is not already locked, so that the module configuration cannot be modified
+ * until a power on reset of the device.
+ *
+ * The locked configuration can be used to ensure that faulty software does not
+ * cause the Watchdog configuration to be changed, preserving the level of
+ * safety given by the module.
+ *
+ * \subsection asfdoc_sam0_wdt_module_window_mode Window Mode
+ * Just as there is a reasonable upper bound to the time the main program loop
+ * should take for each iteration, there is also in many applications a lower
+ * bound, i.e. a \a minimum time for which each loop iteration should run for
+ * under normal circumstances. To guard against a system failure resetting the
+ * Watchdog in a tight loop (or a failure in the system application causing the
+ * main loop to run faster than expected) a "Window" mode can be enabled to
+ * disallow resetting of the Watchdog counter before a certain period of time.
+ * If the Watchdog is not reset \a after the window opens but not \a before the
+ * Watchdog expires, the system will reset.
+ *
+ * \subsection asfdoc_sam0_wdt_module_early_warning Early Warning
+ * In some cases it is desirable to receive an early warning that the Watchdog is
+ * about to expire, so that some system action (such as saving any system
+ * configuration data for failure analysis purposes) can be performed before the
+ * system reset occurs. The Early Warning feature of the Watchdog module allows
+ * such a notification to be requested; after the configured early warning time
+ * (but before the expiry of the Watchdog counter) the Early Warning flag will
+ * become set, so that the user application can take an appropriate action.
+ *
+ * \note It is important to note that the purpose of the Early Warning feature
+ *       is \a not to allow the user application to reset the Watchdog; doing
+ *       so will defeat the safety the module gives to the user application.
+ *       Instead, this feature should be used purely to perform any tasks that
+ *       need to be undertaken before the system reset occurs.
+ *
+ * \subsection asfdoc_sam0_wdt_module_overview_physical Physical Connection
+ *
+ * \ref asfdoc_sam0_wdt_module_int_connections "The figure below" shows how
+ * this module is interconnected within the device.

+ * \note Watchdog Counter of SAM L21/L22 is \a not provided by GCLK, but it uses an
+ *       internal 1KHz OSCULP32K output clock.
+ *
+ * \section asfdoc_sam0_wdt_special_considerations Special Considerations
+ *
+ * On some devices the Watchdog configuration can be fused to be always on in
+ * a particular configuration; if this mode is enabled the Watchdog is not
+ * software configurable and can have its count reset and early warning state
+ * checked/cleared only.

+# ArduinoHttpClient
+
+ArduinoHttpClient is a library to make it easier to interact with web servers from Arduino.
+
+Derived from [Adrian McEwen's HttpClient library](https://github.com/amcewen/HttpClient)
+
+## Dependencies
+
+- Requires a networking hardware and a library that provides transport specific `Client` instance, such as:
+  - [WiFi101](https://github.com/arduino-libraries/WiFi101)
+  - [Ethernet](https://github.com/arduino-libraries/Ethernet)
+  - [WiFi](https://github.com/arduino-libraries/WiFi)
+  - [GSM](https://github.com/arduino-libraries/GSM)
+
+## Usage
+
+In normal usage, handles the outgoing request and Host header.  The returned status code is parsed for you, as is the Content-Length header (if present).
+
+Because it expects an object of type Client, you can use it with any of the networking classes that derive from that.  Which means it will work with WiFiClient, EthernetClient and GSMClient.
+
+See the examples for more detail on how the library is used.
+

+Thank you for opening an issue on an Adafruit Arduino library repository.  To
+improve the speed of resolution please review the following guidelines and
+common troubleshooting steps below before creating the issue:
+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.
+You may delete the guideline and text above to just leave the following details:
+
+- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
+
+- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
+  VERSION HERE**
+
+- List the steps to reproduce the problem below (if possible attach a sketch or
+  copy the sketch code in too): **LIST REPRO STEPS BELOW**

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+Thank you for opening an issue on an Adafruit Arduino library repository.  To
+improve the speed of resolution please review the following guidelines and
+common troubleshooting steps below before creating the issue:
+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.
+You may delete the guideline and text above to just leave the following details:
+
+- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
+
+- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
+  VERSION HERE**
+
+- List the steps to reproduce the problem below (if possible attach a sketch or
+  copy the sketch code in too): **LIST REPRO STEPS BELOW**

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+  WiFi Web Server LED Blink
+
+  A simple web server that lets you blink an LED via the web.
+  This sketch will create a new access point (with no password).
+  It will then launch a new server and print out the IP address
+  to the Serial monitor. From there, you can open that address in a web browser
+  to turn on and off the LED on pin 13.
+
+  If the IP address of your shield is yourAddress:
+    http://yourAddress/H turns the LED on
+    http://yourAddress/L turns it off

+ MDNS WiFi Web Server
+
+ A simple web server that shows the value of the analog input pins,
+ and exposes itself on the MDNS name 'wifi101.local'.
+
+ On Linux (like Ubuntu 15.04) or OSX you can access the web page
+ on the device in a browser at 'http://wifi101.local/'.
+
+ On Windows you'll first need to install the Bonjour Printer Services
+ from:
+   https://support.apple.com/kb/dl999?locale=en_US
+ Then you can access the device in a browser at 'http://wifi101.local/'.
+
+ This example is written for a network using WPA encryption. For
+ WEP or WPA, change the WiFi.begin() call accordingly.
+
+ Circuit:
+ * WiFi shield attached
+ * Analog inputs attached to pins A0 through A5 (optional)

+  WiFi Web Server LED Blink
+
+ A simple web server that lets you blink an LED via the web.
+ This sketch will print the IP address of your WiFi Shield (once connected)
+ to the Serial monitor. From there, you can open that address in a web browser
+ to turn on and off the LED on pin 9.
+
+ If the IP address of your shield is yourAddress:
+ http://yourAddress/H turns the LED on
+ http://yourAddress/L turns it off
+
+ This example is written for a network using WPA encryption. For
+ WEP or WPA, change the WiFi.begin() call accordingly.
+
+ Circuit:
+ * WiFi shield attached
+ * LED attached to pin 9

+# Heatseek Feather Sensor
+
+## Building Project
+
+1. Ensure you're on (at least) version 1.6.13 of the Arduino IDE
+1. Place the contents of the libraries directory in your Arduino user libraries directory.  (Usually `~/Documents/Arduino/libraries`)
+1. Set up WICED Feather using [steps here](https://learn.adafruit.com/introducing-the-adafruit-wiced-feather-wifi/).
+1. Set up M0 Feather using [steps here](https://learn.adafruit.com/adafruit-feather-m0-basic-proto/setup).
+1. Set up M0 WiFi Feather using [steps here](https://learn.adafruit.com/adafruit-feather-m0-wifi-atwinc1500/using-the-wifi-module). Be sure to do the version check as described.
+1. In `user_config.h`, uncomment the appropriate line depending on which microprocessor board you are using.  Only one board type line in this file should be uncommented.
+
+## Software
+
+### Outline
+
+1. Prompt user to set RTC clock time if necessary.  (TODO: set this by web request).
+1. If last reading time exceeds reading interval, take a new reading.
+1. Store the reading on the SD card.
+1. Store the reading time on SD card for comparison against reading interval.
+
+### Notes
+
+- Always prioritize logging data to SD card.  The microprocessor should always reboot and continue taking readings if there is a problem transmitting the data.
+- TODO: Ensure device is not on battery power prior to writing to SD card.

+# feather_sensor_transmit_lte
+
+A Particle project named feather_sensor_transmit_lte
+
+## Welcome to your project!
+
+Every new Particle project is composed of 3 important elements that you'll see have been created in your project directory for feather_sensor_transmit_lte.
+
+#### ```/src``` folder:  
+This is the source folder that contains the firmware files for your project. It should *not* be renamed. 
+Anything that is in this folder when you compile your project will be sent to our compile service and compiled into a firmware binary for the Particle device that you have targeted.
+
+If your application contains multiple files, they should all be included in the `src` folder. If your firmware depends on Particle libraries, those dependencies are specified in the `project.properties` file referenced below.
+
+#### ```.ino``` file:
+This file is the firmware that will run as the primary application on your Particle device. It contains a `setup()` and `loop()` function, and can be written in Wiring or C/C++. For more information about using the Particle firmware API to create firmware for your Particle device, refer to the [Firmware Reference](https://docs.particle.io/reference/firmware/) section of the Particle documentation.
+
+#### ```project.properties``` file:  
+This is the file that specifies the name and version number of the libraries that your project depends on. Dependencies are added automatically to your `project.properties` file when you add a library to a project using the `particle library add` command in the CLI or add a library in the Desktop IDE.
+
+## Adding additional files to your project
+
+#### Projects with multiple sources
+If you would like add additional files to your application, they should be added to the `/src` folder. All files in the `/src` folder will be sent to the Particle Cloud to produce a compiled binary.
+
+#### Projects with external libraries
+If your project includes a library that has not been registered in the Particle libraries system, you should create a new folder named `/lib/<libraryname>/src` under `/<project dir>` and add the `.h`, `.cpp` & `library.properties` files for your library there. Read the [Firmware Libraries guide](https://docs.particle.io/guide/tools-and-features/libraries/) for more details on how to develop libraries. Note that all contents of the `/lib` folder and subfolders will also be sent to the Cloud for compilation.
+
+## Compiling your project
+
+When you're ready to compile your project, make sure you have the correct Particle device target selected and run `particle compile <platform>` in the CLI or click the Compile button in the Desktop IDE. The following files in your project folder will be sent to the compile service:
+
+- Everything in the `/src` folder, including your `.ino` application file
+- The `project.properties` file for your project
+- Any libraries stored under `lib/<libraryname>/src`

+The Arduino SdFat library provides read/write access to FAT16/FAT32
+file systems on SD/SDHC flash cards.
+
+SdFat requires Arduino 1.6x or greater.
+
+Key changes:
+
+Support for multiple SPI ports now uses a pointer to a SPIClass object.
+
+See the STM32Test example.
+```
+explicit SdFat(SPIClass* spiPort);
+\\ or
+explicit SdFatEX(SPIClass* spiPort);
+```
+
+Open flags now follow POSIX conventions.  O_RDONLY is the same as O_READ and O_WRONLY is the
+same as O_WRITE. One and only one of of the mode flags, O_RDONLY, O_RDWR, or
+O_WRONLY is required.
+ 
+Open flags for Particle Gen3 and ARM boards are now defined by fcntl.h.
+See SdFatConfig.h for options.
+
+Support for particle Gen3 devices.
+
+New cluster allocation algorithm.
+
+Please read changes.txt and the html documentation in the extras folder for more information.
+
+Please report problems as issues.
+
+A number of configuration options can be set by editing SdFatConfig.h
+define macros.  See the html documentation for details
+
+Please read the html documentation for this library.  Start with
+html/index.html and read the Main Page.  Next go to the Classes tab and
+read the documentation for the classes SdFat, SdFatEX, SdBaseFile,
+SdFile, File, StdioStream, ifstream, ofstream, and others.
+ 
+Please continue by reading the html documentation in SdFat/extras/html

+ *
+ * Edit the configuration constants below to set the sample pins, sample rate,

+ *
+ * Each 512 byte data block in the file has a four byte header followed by up
+ * to 508 bytes of data. (508 values in 8-bit mode or 254 values in 10-bit mode)
+ * Each block contains an integral number of samples with unused space at the
+ * end of the block.

+/**
+ * This program logs data to a binary file.  Functions are included
+ * to convert the binary file to a csv text file.
+ *
+ * Samples are logged at regular intervals.  The maximum logging rate
+ * depends on the quality of your SD card and the time required to
+ * read sensor data.  This example has been tested at 500 Hz with
+ * good SD card on an Uno.  4000 HZ is possible on a Due.
+ *
+ * If your SD card has a long write latency, it may be necessary to use
+ * slower sample rates.  Using a Mega Arduino helps overcome latency
+ * problems since 12 512 byte buffers will be used.
+ *
+ * Data is written to the file using a SD multiple block write command.

+/**
+ * This program logs data to a binary file.  Functions are included
+ * to convert the binary file to a csv text file.
+ *
+ * Samples are logged at regular intervals.  The maximum logging rate
+ * depends on the quality of your SD card and the time required to
+ * read sensor data.  This example has been tested at 500 Hz with
+ * good SD card on an Uno.  4000 HZ is possible on a Due.
+ *
+ * If your SD card has a long write latency, it may be necessary to use
+ * slower sample rates.  Using a Mega Arduino helps overcome latency
+ * problems since 12 512 byte buffers will be used.
+ *
+ * Data is written to the file using a SD multiple block write command.

+/**
+ * This program logs data to a binary file.  Functions are included
+ * to convert the binary file to a csv text file.
+ *
+ * Samples are logged at regular intervals.  The maximum logging rate
+ * depends on the quality of your SD card and the time required to
+ * read sensor data.  This example has been tested at 500 Hz with
+ * good SD card on an Uno.  4000 HZ is possible on a Due.
+ *
+ * If your SD card has a long write latency, it may be necessary to use
+ * slower sample rates.  Using a Mega Arduino helps overcome latency
+ * problems since 12 512 byte buffers will be used.
+ *
+ * Data is written to the file using a SD multiple block write command.

+Static Tests of the Arduino Internal ADC.
+
+Several people have asked about the DC accuracy of the Arduino ADC when used in my data logging applications at slow sample rates.
+
+Here are my results of some "hobby level" measurements of the Arduino ADC.
+
+One question is how important is the ADC clock rate.  I did measurents for an ADC clock rate of 125 kHz to 2MHz.
+
+Another question is how much does Noise Reduction Mode help.  I did a series of measurements using this mode.
+
+Noise Reduction Mode only reduced the mean absolute error slightly.
+
+I do calibration to remove Offset Error and Gain Error.  Calibration is very important for good accuracy.
+
+These tests depend on the Arduino voltage regulator providing a stable voltage during the tests.  The Arduino ADC reference voltage is Vcc for these tests.  This may not be realistic for practical applications
+
+Integral Non-linearity (INL) is the main remaining source of error.
+
+Here are my results for static (DC) tests of the internal ADC for three UNOs.
+
+The Arduinos are powered by a high quality nine volt power supply.
+
+These tests measure a DC level so do not include problems due to time jitter, S/H time, and other dynamic errors.
+There are several studies of the dynamic behavior of the Arduino ADC that determine ENOB (Effective Number Of Bits).
+
+I used a shield with a 12-bit MCP4921 DAC to generate voltage levels. This ADC has an output buffer so it provides a very low impedance source.
+
+I measured the voltage of the DAC with a calibrated 18-bit MCP3422 ADC on the shield.
+
+I used DAC levels from 20 to 4075 to avoid zero offset errors at low voltages and DAC buffer problems at high voltages.
+
+Each series of measurements has 4056 data points.
+
+This is a voltage range of about 0.023 to 4.972 volts.
+
+I calibrated the Arduino ADC for each series of measurements with a linear fit of the form.
+
+v = a + b*adcValue
+
+Errors are the difference between the value measured with the 18-bit ADC and the calibrated value measured with the AVR ADC.
+
+I also show the results for no calibration, the NoCal column, using the datasheet formula.
+
+Vin = Vref*adcValue/1024
+
+
+The rows in the tables tables are.
+
+Min - minimum error in millivolts
+
+Max - maximum error in millivolts
+
+MAE - mean absolute error in millivolts
+
+
+The columns in the tables are:
+
+Ideal - results for a perfect 10-bit ADC for comparison.
+
+NoCal - datasheet formula (5/1024)*adcValue with Noise Reduction Mode.
+
+NR128 - Noise Reduction mode with Prescaler of 128 (ADC clock of 125 kHz).
+
+PS128 - analogRead with Prescaler of 128 (ADC clock of 125 kHz).
+

+AnalogBinLogger.ino logs analog data to a binary SD file at high rates.
+
+Samples are logged at regular intervals by using timer1.  Timer/Counter1
+Compare Match B is used to trigger the ADC for the first pin in a sample.
+The ADC is triggered for remaining sample pins in the ADC conversion complete
+interrupt routine.
+
+Data is captured in the ADC interrupt routine and saved in 512 byte buffers.
+
+Buffered data is written to the SD in a function called from loop().  The
+entire data set is written to a large contiguous file as a single multi-block
+write.  This reduces write latency problems.
+
+Many inexpensive SD cards work well at lower rates.  I used a $6.00
+SanDisk 4 GB class 4 card for testing.
+
+SanDisk class 4 cards work well at fairly high rates.  I used the 4 GB SanDisk
+card to log a single pin at 40,000 samples per second.
+
+You may need to increase the time between samples if your card has higher
+latency.  Using a Mega Arduino can help since it has more buffering.
+
+The bintocsv folder contains a PC program for converting binary files to
+CSV files.  Build it from the included source files.  bintocvs is a command line program.
+
+bintocsv binFile csvFile 
+
+AnalogBinLogger requires a recent version of the SdFat library.  The SdFat
+folder contains a beta version I used for development.
+
+The latest stable version is here:
+http://code.google.com/p/sdfatlib/downloads/list
+
+You also need to install the included BufferedWriter library.  It provides
+fast text formatting.
+
+Example data for a 2 kHz sine wave logged at 40,000 samples per second is
+shown in DATA.PNG and FFT.PNG shows a FFT of the data.  See ExcelFFT.pdf
+in the ADCdocs folder for details on calculating a FFT.
+
+The accuracy of the ADC samples depends on the ADC clock rate.  See the
+ADC_ENOB.PNG file for a plot of accuracy vs ADC clock frequency.
+
+See files in the ADCdocs folder for more information on ADC accuracy.
+
+To modify this program you will need a good knowledge of the Arduino
+ADC, timer1 and C++ programming.  This is not for the newbie.
+
+I have an LED and resistor connected to pin 3 to signal fatal errors and
+data overruns. Fatal errors are indicated by a blinking led.  Overrun errors
+are indicated by a solid lit led.  The count of samples dropped is written
+to the SD and data logging continues.
+
+You can disable the error led feature by setting the error pin number negative:
+
+To use AnalogBinLogger, install these items. 
+
+Place the BufferWriter and SdFat folders in your sketchbook libraries folder.
+
+Place the AnalogIsrLogger folder in your sketchbook folder.
+
+You must edit the configuration constants at the beginning of the program 
+to set the sample pins, sample rate, and other configuration values.
+
+Initially the program is setup to log the first five analog pins at 5000
+samples per second.  Change these values to suit your needs.
+
+See RateTable.txt for maximum allowed sample rates vs pin count and ADC clock
+frequency.
+
+The program has four commands:
+
+c - convert file to CSV
+d - dump data to Serial
+e - overrun error details
+r - record ADC data
+
+All commands can be terminated by entering a character from the serial monitor.
+
+The c command converts the current binary file to a text file.  Entering a
+character on the serial monitor terminates the command.
+
+The d command converts the binary file to text and displays it on the serial
+monitor.  Entering a character on the serial monitor terminates the command.
+
+The e command displays details about overruns in the current binary file.
+Data overruns happen when data samples are lost due to long write latency
+of the SD.
+
+The r command will record ADC data to a binary file.  It will terminate
+when a character is entered on the serial monitor or the the maximum file
+block count has been reached.
+
+A number of program options can be set by changing constants at the beginning
+of the program.

+\mainpage Arduino %SdFat Library
+<CENTER>Copyright &copy 2012-2018 by William Greiman
+</CENTER>
+
+\section Intro Introduction
+The Arduino %SdFat Library is a minimal implementation of FAT16 and FAT32
+file systems on SD flash memory cards. Standard SD and high capacity SDHC
+cards are supported.
+
+Experimental support for FAT12 can be enabled by setting FAT12_SUPPORT
+nonzero in SdFatConfig.h.
+
+The %SdFat library supports Long %File Names or short 8.3 names.
+Edit the SdFatConfig.h file to select short or long file names.
+
+The main classes in %SdFat are SdFat, SdFatEX, SdFatSoftSpi, SdFatSoftSpiEX,
+SdBaseFile, SdFile, File, StdioStream, \ref fstream, \ref ifstream,
+and \ref ofstream.
+
+The SdFat, SdFatEX, SdFatSoftSpi and SdFatSoftSpiEX classes maintain a
+FAT volume, a current working directory, and simplify initialization
+of other classes. The SdFat and SdFatEX classes uses a fast custom hardware SPI
+implementation.  The SdFatSoftSpi and SdFatSoftSpiEX classes uses software SPI.
+
+the SdFatEX and SdFatSoftSpiEX use extended multi-block I/O for enhanced
+performance.  These classes must have exclusive use of the SPI bus.
+
+The SdBaseFile class provides basic file access functions such as open(),
+binary read(), binary write(), close(), remove(), and sync(). SdBaseFile
+is the smallest file class.
+
+The SdFile class has all the SdBaseFile class functions plus the Arduino
+Print class functions.
+
+The File class has all the SdBaseFile functions plus the functions in
+the Arduino SD.h File class. This provides compatibility with the
+Arduino SD.h library.
+
+The StdioStream class implements functions similar to Linux/Unix standard
+buffered input/output.
+
+The \ref fstream class implements C++ iostreams for both reading and writing
+text files.
+
+The \ref ifstream class implements C++ iostreams for reading text files.
+
+The \ref ofstream class implements C++ iostreams for writing text files.
+
+The classes \ref ifstream, \ref ofstream, \ref istream, and \ref ostream
+follow the C++ \ref iostream standard when possible.
+
+There are many tutorials and much documentation about using C++ iostreams
+on the web.
+
+http://www.cplusplus.com/  is a good C++ site for learning iostreams.
+
+The classes \ref ibufstream and \ref obufstream format and parse character
+ strings in memory buffers.
+
+the classes ArduinoInStream and ArduinoOutStream provide iostream functions
+for Serial, LiquidCrystal, and other devices.
+
+A number of example are provided in the %SdFat/examples folder.  These were
+developed to test %SdFat and illustrate its use.
+
+\section Install Installation
+
+You must manually install SdFat by copying the SdFat folder from the download
+package to the Arduino libraries folder in your sketch folder.
+
+See the Manual installation section of this guide.
+
+http://arduino.cc/en/Guide/Libraries
+
+\section SDconfig SdFat Configuration
+
+Several configuration options may be changed by editing the SdFatConfig.h
+file in the %SdFat folder.
+
+Set USE_LONG_FILE_NAMES nonzero to enable Long %File Names.  By default,
+Long %File Names are enabled. For the leanest fastest library disable
+Long %File Names.  Long %File names require extra flash but no extra RAM.
+Opening Long %File Names can be slower than opening Short %File Names.
+Data read and write performance is not changed by the type of %File Name.
+
+If the symbol ENABLE_EXTENDED_TRANSFER_CLASS is nonzero, the class SdFatEX
+will be defined. If the symbol ENABLE_SOFTWARE_SPI_CLASS is also nonzero,
+the class SdFatSoftSpiEX will be defined.
+These classes used extended multi-block SD I/O for better performance.
+the SPI bus may not be shared with other devices in this mode.
+
+Set USE_STANDARD_SPI_LIBRARY and  ENABLE_SOFTWARE_SPI_CLASS to
+enable various SPI options. set USE_STANDARD_SPI_LIBRARY to use the standard
+Arduino SPI library. set ENABLE_SOFTWARE_SPI_CLASS to enable the SdFatSoftSpi
+class which uses software SPI.
+
+To enable SD card CRC checking set USE_SD_CRC nonzero.
+
+Set FAT12_SUPPORT nonzero to enable use of FAT12 volumes.
+FAT12 has not been well tested and requires additional flash.
+
+\section SDPath Paths and Working Directories
+
+Relative paths in SdFat are resolved in a manner similar to Windows.
+
+Each instance of SdFat has a current directory.  In SdFat this directory
+is called the volume working directory, vwd.  Initially this directory is
+the root directory for the volume.
+
+The volume working directory is changed by calling SdFat::chdir(path).
+
+The call sd.chdir("/2014") will change the volume working directory
+for sd to "/2014", assuming "/2014" exists.
+
+Relative paths for SdFat member functions are resolved by starting at
+the volume working directory.
+
+For example, the call sd.mkdir("April") will create the directory
+"/2014/April" assuming the volume working directory is "/2014".
+
+SdFat has a current working directory, cwd, that is used to resolve paths
+for file.open() calls.
+
+For a single SD card the current working directory is always the volume
+working directory for that card.
+
+For multiple SD cards the current working directory is set to the volume
+working directory of a card by calling the SdFat::chvol() member function.
+The chvol() call is like the Windows \<drive letter>: command.
+
+The call sd2.chvol() will set the current working directory to the volume
+working directory for sd2.
+
+If the volume working directory for sd2 is "/music" the call
+
+file.open("BigBand.wav", O_READ);
+
+will then open "/music/BigBand.wav" on sd2.
+
+The following functions are used to change or get current directories.
+See the html documentation for more information.
+@code
+bool SdFat::chdir(bool set_cwd = false);
+bool SdFat::chdir(const char* path, bool set_cwd = false);
+void SdFat::chvol();
+SdBaseFile* SdFat::vwd();
+static SdBaseFile* SdBaseFile::cwd();
+@endcode
+
+\section SDcard SD\SDHC Cards
+
+Arduinos access SD cards using the cards SPI protocol.  PCs, Macs, and
+most consumer devices use the 4-bit parallel SD protocol.  A card that
+functions well on A PC or Mac may not work well on the Arduino.
+
+Most cards have good SPI read performance but cards vary widely in SPI
+write performance.  Write performance is limited by how efficiently the
+card manages internal erase/remapping operations.  The Arduino cannot
+optimize writes to reduce erase operations because of its limit RAM.
+
+SanDisk cards generally have good write performance.  They seem to have
+more internal RAM buffering than other cards and therefore can limit
+the number of flash erase operations that the Arduino forces due to its
+limited RAM.
+
+\section Hardware Hardware Configuration
+
+%SdFat was developed using an
+<A HREF = "http://www.adafruit.com/"> Adafruit Industries</A>
+Data Logging Shield.
+
+The hardware interface to the SD card should not use a resistor based level
+shifter.  %SdFat sets the SPI bus frequency to 8 MHz which results in signal
+rise times that are too slow for the edge detectors in many newer SD card
+controllers when resistor voltage dividers are used.
+
+The 5 to 3.3 V level shifter for 5 V Arduinos should be IC based like the
+74HC4050N based circuit shown in the file SdLevel.png.  The Adafruit Wave Shield
+uses a 74AHC125N.  Gravitech sells SD and MicroSD Card Adapters based on the
+74LCX245.
+
+If you are using a resistor based level shifter and are having problems try
+setting the SPI bus frequency to 4 MHz.  This can be done by using
+card.init(SPI_HALF_SPEED) to initialize the SD card.
+
+A feature to use software SPI is available.  Software SPI is slower
+than hardware SPI but allows any digital pins to be used.  See
+SdFatConfig.h for software SPI definitions.
+
+\section comment Bugs and Comments
+
+If you wish to report bugs or have comments, send email to
+fat16lib@sbcglobal.net.  If possible, include a simple program that illustrates
+the bug or problem.
+
+\section Trouble Troubleshooting
+
+The two example programs QuickStart, and SdInfo are useful for troubleshooting.
+
+A message like this from SdInfo with errorCode 0X1 indicates the SD card
+is not seen by SdFat.  This is often caused by a wiring error and reformatting
+the card will not solve the problem.
+<PRE>
+cardBegin failed
+SD errorCode: 0X1
+SD errorData: 0XFF
+</PRE>
+Here is a similar message from QuickStart:
+<PRE>
+SD initialization failed.
+Do not reformat the card!
+Is the card correctly inserted?
+Is chipSelect set to the correct value?
+Does another SPI device need to be disabled?
+Is there a wiring/soldering problem?
+
+errorCode: 0x1, errorData: 0xff
+</PRE>
+Here is a message from QuickStart that indicates a formatting problem:
+<PRE>
+Card successfully initialized.
+Can't find a valid FAT16/FAT32 partition.
+Try reformatting the card.  For best results use
+the SdFormatter program in SdFat/examples or download
+and use SDFormatter from www.sdcard.org/downloads.

+
+SdFat supports Long File Names.  Long names in SdFat are limited to 7-bit
+ASCII characters in the range 0X20 - 0XFE The following are reserved characters:
+    <ul>
+    <li>< (less than)
+    <li>> (greater than)
+    <li>: (colon)
+    <li>" (double quote)
+    <li>/ (forward slash)
+    <li>\ (backslash)
+    <li>| (vertical bar or pipe)
+    <li>? (question mark)
+    <li>* (asterisk)
+    </ul>
+%SdFat uses a slightly restricted form of short names.
+Short names are limited to 8 characters followed by an optional period (.)
+and extension of up to 3 characters.  The characters may be any combination
+of letters and digits.  The following special characters are also allowed:
+
+$ % ' - _ @ ~ ` ! ( ) { } ^ # &
+
+Short names are always converted to upper case and their original case
+value is lost.  Files that have a base-name where all characters have the
+same case and an extension where all characters have the same case will
+display properly.  Examples this type name are UPPER.low, lower.TXT,
+UPPER.TXT, and lower.txt.
+
+An application which writes to a file using print(), println() or
+write() must close the file or call sync() at the appropriate time to
+force data and directory information to be written to the SD Card.
+
+Applications must use care calling sync()
+since 2048 bytes of I/O is required to update file and
+directory information.  This includes writing the current data block, reading
+the block that contains the directory entry for update, writing the directory
+block back and reading back the current data block.
+
+It is possible to open a file with two or more instances of a file object.
+A file may be corrupted if data is written to the file by more than one
+instance of a file object.
+
+\section HowTo How to format SD Cards as FAT Volumes
+
+The best way to restore an SD card's format on a PC or Mac is to use
+SDFormatter which can be downloaded from:
+
+http://www.sdcard.org/downloads
+
+A formatter program, SdFormatter.ino, is included in the
+%SdFat/examples/SdFormatter directory.  This program attempts to
+emulate SD Association's SDFormatter.
+
+SDFormatter aligns flash erase boundaries with file
+system structures which reduces write latency and file system overhead.
+
+The PC/Mac SDFormatter does not have an option for FAT type so it may format
+very small cards as FAT12.  Use the SdFat formatter to force FAT16
+formatting of small cards.
+
+Do not format the SD card with an OS utility, OS utilities do not format SD
+cards in conformance with the SD standard.
+
+You should use a freshly formatted SD card for best performance.  FAT
+file systems become slower if many files have been created and deleted.
+This is because the directory entry for a deleted file is marked as deleted,
+but is not deleted.  When a new file is created, these entries must be scanned
+before creating the file.  Also files can become
+fragmented which causes reads and writes to be slower.
+
+\section ExampleFilder Examples
+
+A number of examples are provided in the SdFat/examples folder.
+See the html documentation for a list.
+
+To access these examples from the Arduino development environment
+go to:  %File -> Examples -> %SdFat -> \<program Name\>

+
+15 Aug 2016
+
+New classes SdFatEX and SdFatSoftSpiEX with Extended SD I/O.
+These classes provide higher performance but require a dedicated
+SPI port.
+
+The symbol SD_SPI_CONFIGURATION has been replaced by three symbols,
+ENABLE_EXTENDED_TRANSFER_CLASS, USE_STANDARD_SPI_LIBRARY, and
+ENABLE_SOFTWARE_SPI_CLASS to define the SPI configuration.
+
+SPI transactions are always used.
+
+The SPI divisor has been replaced by SPISettings.  A new macro
+is used to generate SPISettings. This call will use the highest
+speed supported by the board that is not over 50 MHz.
+
+ sd.begin(CS_PIN, SD_SCK_MHZ(50));

+error message or set ALLOW_DEPRECATED_FUNCTIONS nonzero.
+
+A key change was to remove sd.init(spiRateID, chipSelect) in favor of
+sd.begin(chipSelect, spiRateID).  The difference between these two is
+the order of the arguments which has caused serious confusion at times.
+
+A massive number of internal changes have been made.  There are over 2600
+lines in the diff file of this version and the 20120719 version.
+
+20 Oct 2012

+
+26 Mar 2012
+
+Removed definition for SS_PIN, MISO_PIN, MOSI_PIN, and SCK_PIN.  Used the
+Arduino 1.0 symbols SS, MISO, MOSI, and SCK.
+
+Added Arduino style SdFat::begin(chipSelect, spiSpeed);
+
+Added options for SD crc checking.  Enabling crc checking increases reliability
+at the cost of speed.  Edit SdFatConfig.h to select CRC options.
+
+Override Print::getWriteError() and Print::clearWriteError() to use
+SdBaseFile functions.
+
+Many internal changes.
+
+08 Jan 2012
+
+Changes to allow use of the SerialPort library.
+
+Error messages and output from programs are now sent to a stdOut Print
+stream.
+
+The default stdOut is a small non-interrupt driven class that outputs messages
+to serial port zero.  This allows an alternate Serial library like SerialPort
+to be used with SdFat.
+
+You can redirect stdOut with SdFat::setStdOut(Print* stream) and
+get the current stdOut stream with SdFat::stdOut().
+
+If USE_SERIAL_FOR_STD_OUT in SdFatConfig.h is nonzero, the Arduino Serial
+object will be used as the default for stdOut.
+
+
+05 Dec 2011
+
+Changes for Arduino 1.0
+
+
+17 Sep 2011
+
+Changes for Arduino 1.0 beta 4
+
+Improved SPI handling
+
+02 Sep 2011
+--------------------------------------------------------------------------------
+Warning:
+Several changes are not backward compatible with the previous
+version of SdFat.
+
+The function cwd() was renamed vwd() to allow multiple SD cards.
+
+The type SdBaseFile was added to the class hierarchy to avoid conflicts with
+other Arduino libraries that are derived from the Print class.  Directory
+files should be declared type SdBaseFile.
+--------------------------------------------------------------------------------
+
+Added support for multiple SD cards.
+
+Change the name of SdFat::cwd() to SdFat::vwd() since the volume
+working directory is not the current working directory with
+multiple SD cards.
+
+Added the static function SdBaseFile::cwd() to return a pointer
+to the current working directory.
+
+Added the TwoCards.pde example to demonstrate use of multiple SD cards.
+
+Added readCSV.pde example to demonstrate iostream extractors.
+
+Added bool SdBaseFile::timestamp(SdBaseFile* file) to copy one
+file's timestamps to another file.
+
+Improved messages in the QuickStart.pde example.
+
+Added maximum latency test to the bench.pde example.
+
+Rearanged class hierarchy to fix conflicts with Flash.h and other Adruino
+libraries.  Print is no longer a private parent of file stream classes.
+
+Added high speed multiple block read functions to Sd2Card.
+
+Changed include files in SdFatUtil.h
+
+Removed option to write protect block zero of an SD card.
+
+Changes for Arduino 1.0.
+
+02 Jul 2011
+
+This is a major update based on previous beta versions.
+Read all changes since 10 Oct 2001
+
+Simplified examples in extra/examplesV1
+
+28 Jun 2011
+
+This is a release candidate to replace sdfatlib20101010.
+
+Initialize SPI bus before every access.
+
+Improved write multiple block functions for fast data logging.
+
+SdVolume::cacheClear() returns zero if it fails.
+
+Documentation changes.
+
+04 Jun 2011
+
+Added SdFatTestSuite and fixed bugs found by test programs.
+
+Added functions:
+
+bool SdFat::truncate(const char* path, uint32_t length); 
+
+int16_t SdFile::fgets(char* str, int16_t num, char* delim);
+
+11 May 2011
+
+Added QuickStart sketch and QuickStart.txt file for fast hardware test.
+
+Added several new examples.
+
+Version of ls() that can write to any Print object.
+
+New functions including freeClusterCount(), openNext() rename().
+
+14 Apr 2011
+
+Total rewrite to add iostreams and SdFat class with current working directory.
+Old API maintained for backward compatibility.
+
+
+27 Nov 2010
+
+
+Added experimental support for FAT12.  This can be enabled by setting
+FAT12_SUPPORT nonzero in SdFatConfig.h.
+
+Added an experimental sketch, SdFatFormatter.pde, to format SD cards as
+FAT16 and SDHC cards as FAT32.  See SdFat/examples/SdFormatter.
+
+The return type of SdVolume::cacheClear was changed to cache_t*.
+
+Many internal changes to support FAT12 and formatting SD/SDHC cards.
+
+
+10 Oct 2010
+
+Added Mega 2560.
+
+Fixed rmRfStar() bug.
+
+Fixed Sanguino NULL definition.
+
+18 Aug 2010
+
+Optimized write() for append at end of file.  Up to 50% faster sequential write.
+
+13 Aug 2010
+
+Added the following function to allow the SD chip select pin to be set
+at runtime.  Warning - if the hardware SS pin is not used as chip select, 
+the hardware SS pin will be set to output mode by init(). An avr processor
+will not function as an SPI master unless SS is set to output mode.
+
+uint8_t Sd2Card::init(uint8_t sckRateID, uint8_t chipSelectPin);
+
+Added more SPI clock rate choices.  The above init() function and 
+uint8_t Sd2Card::init(uint8_t sckRateID) call the new function 
+uint8_t Sd2Card::setSckRate(uint8_t sckRateID).
+
+setSckRate() sets the SPI clock rate to F_CPU/pow(2, 1 + sckRateID).
+On an 16 MHz cpu this ranges from 8 MHz for sckRateId = 0 to 125 kHz
+for sckRateID = 6.  This function must be called after the init() call.
+
+Modified most examples to call card.init(SPI_HALF_SPEED) to avoid SPI bus
+errors with breadboards and jumpers.  This sets the SPI speed to F_CPU/4.
+Defined SPI_FULL_SPEED so init(SPI_FULL_SPEED) sets the SPI speed to F_CPU/2.
+
+Added the following  function to cancel date/time callback. This function
+must now be used instead of dateTimeCallback(NULL).
+
+static void SdFat::dateTimeCallbackCancel(void);
+
+
+The following member functions have been added for users who wish to avoid
+calls to functions with non-const references.
+
+uint8_t SdFile::contiguousRange(uint32_t* bgnBlock, uint32_t* endBlock);
+uint8_t SdFile::createContiguous(SdFile* dirFile,
+  const char* fileName, uint32_t size);
+static void SdFile::dateTimeCallback(
+  void (*dateTime)(uint16_t* date, uint16_t* time));
+uint8_t SdFile::dirEntry(dir_t* dir);

+
+The deprecated function can be disabled by editing SdFat.h and setting
+#define ALLOW_DEPRECATED_FUNCTIONS 0
+
+Fixed file modify time for file rewrite.
+
+Major internal cleanup/reformat based on Google cpplint.py code style.
+
+New Sd2Card::init() algorithm.
+
+New SdFatInfo sketch for modified SdReadData() and other internal changes.
+
+Modified examples to eliminate deprecated functions.
+
+11 Jun 2010
+Added definitions for Teensy to ArduinoPins.h (Paul Stoffregen)
+
+Added troubleshooting.txt
+
+
+23 Dec 2009
+
+Added Software SPI capability.  See Sd2Card.h
+
+Defining MEGA_SOFT_SPI allows an unmodified Adafruit GPS Shield to be used
+on Mega Arduinos.  Software SPI works well with GPS Shield V1.1 
+but many SD cards will fail with GPS Shield V1.0.
+
+Added file ArduinoPins.h for pin definitions.
+
+More error printout in examples.
+
+
+25 Nov 2009
+
+Added new functions for SdFile class:
+
+dateTimeCallback(), dirEntry(), isRoot(), isSubDir, ls(), 
+makeDir(), printDirName(), printFatDate(), printFatTime(), 
+printTwoDigits(), rmDir(), and rmRStar().
+
+Added new examples to test and illustrate use of new functions.
+
+Removed sdCard() from SdFile class.
+
+Fixed several bugs.
+
+
+
+
+12 Nov 2009
+
+Major rewrite of the version of SdFat that was included with
+the WaveRP library.  
+
+This is a preview that is being released to obtain comments
+from several colleagues and future users.

+ * \defgroup asfdoc_sam0_system_clock_group SAM System Clock Management Driver (SYSTEM CLOCK)
+ *
+ * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides an interface for the configuration
+ * and management of the device's clocking related functions. This includes
+ * the various clock sources, bus clocks, and generic clocks within the device,

+ * prescaling of clocks to various internal peripherals.
+ *
+ * The following peripherals are used by this module:
+ *
+ * - GCLK (Generic Clock Management)
+ * - PM (Power Management)
+ * - SYSCTRL (Clock Source Control)
+ *
+ * The following devices can use this module:
+ *  - Atmel | SMART SAM D20/D21
+ *  - Atmel | SMART SAM R21
+ *  - Atmel | SMART SAM D10/D11
+ *  - Atmel | SMART SAM DA0/DA1

+ * \section asfdoc_sam0_system_clock_module_overview Module Overview
+ * The SAM devices contain a sophisticated clocking system, which is designed
+ * to give the maximum flexibility to the user application. This system allows
+ * a system designer to tune the performance and power consumption of the device
+ * in a dynamic manner, to achieve the best trade-off between the two for a
+ * particular application.
+ *
+ * This driver provides a set of functions for the configuration and management

+ * \subsection asfdoc_sam0_system_clock_module_overview_clock_sources Clock Sources
+ * The SAM devices have a number of master clock source modules, each of
+ * which being capable of producing a stabilized output frequency, which can then
+ * be fed into the various peripherals and modules within the device.
+ *
+ * Possible clock source modules include internal R/C oscillators, internal
+ * DFLL modules, as well as external crystal oscillators and/or clock inputs.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_cpu_clock CPU / Bus Clocks
+ * The CPU and AHB/APBx buses are clocked by the same physical clock source
+ * (referred in this module as the Main Clock), however the APBx buses may
+ * have additional prescaler division ratios set to give each peripheral bus a
+ * different clock speed.
+ *
+ * The general main clock tree for the CPU and associated buses is shown in
+ * \ref asfdoc_sam0_system_clock_module_clock_tree "the figure below".

+ * \subsection asfdoc_sam0_system_clock_module_overview_clock_masking Clock Masking
+ * To save power, the input clock to one or more peripherals on the AHB and APBx
+ * buses can be masked away - when masked, no clock is passed into the module.
+ * Disabling of clocks of unused modules will prevent all access to the masked
+ * module, but will reduce the overall device power consumption.
+ *
+ * \subsection asfdoc_sam0_system_clock_module_overview_gclk Generic Clocks
+ * Within the SAM devices there are a number of Generic Clocks; these are used to
+ * provide clocks to the various peripheral clock domains in the device in a
+ * standardized manner. One or more master source clocks can be selected as the
+ * input clock to a Generic Clock Generator, which can prescale down the input
+ * frequency to a slower rate for use in a peripheral.
+ *
+ * Additionally, a number of individually selectable Generic Clock Channels are
+ * provided, which multiplex and gate the various generator outputs for one or
+ * more peripherals within the device. This setup allows for a single common
+ * generator to feed one or more channels, which can then be enabled or disabled
+ * individually as required.

+ * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_generators Generic Clock Generators
+ * Each Generic Clock generator within the device can source its input clock
+ * from one of the provided Source Clocks, and prescale the output for one or
+ * more Generic Clock Channels in a one-to-many relationship. The generators
+ * thus allow for several clocks to be generated of different frequencies,
+ * power usages, and accuracies, which can be turned on and off individually to
+ * disable the clocks to multiple peripherals as a group.
+ *
+ * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_channels Generic Clock Channels
+ * To connect a Generic Clock Generator to a peripheral within the
+ * device, a Generic Clock Channel is used. Each peripheral or
+ * peripheral group has an associated Generic Clock Channel, which serves as the
+ * clock input for the peripheral(s). To supply a clock to the peripheral
+ * module(s), the associated channel must be connected to a running Generic
+ * Clock Generator and the channel enabled.

+ *
+ * There are no prerequisites for this module.
+ *
+ * \section asfdoc_sam0_i2s_module_overview Module Overview
+ *
+ * The I2S provides bidirectional, synchronous, digital audio link with external
+ * audio devices through these signal pins:
+ *  - Serial Data (SDm)
+ *  - Frame Sync (FSn)
+ *  - Serial Clock (SCKn)
+ *  - Master Clock (MCKn)
+ *
+ * The I2S consists of 2 Clock Units and 2 Serializers, which can be separately
+ * configured and enabled, to provide varies functionalities as follow:
+ *  - Communicate to Audio CODECs as Master or Slave, or provides clock and
+ *    frame sync signals as Controller
+ *  - Communicate to DAC or ADC through dedicated I2S serial interface
+ *  - Communicate to multi-slot or multiple stereo DACs or ADCs, via
+ *    Time Division Multiplexed (TDM) format
+ *  - Reading mono or stereo MEMS microphones, using the Pulse Density
+ *    Modulation (PDM) interface
+ *
+ * The I2S supports compact stereo data word, where left channel data bits are
+ * in lower half and right channel data bits are in upper half. It reduces the
+ * number of data words for stereo audio data and the DMA bandwidth.
+ *
+ * In master mode, the frame is configured by number of slots and slot size, and
+ * allows range covering 16fs to 1024fs MCK, to provide oversampling clock to an
+ * external audio CODEC or digital signal processor (DSP).
+ *
+ * A block diagram of the I2S can be seen in
+ * \ref asfdoc_sam0_i2s_module_block_diagram "the figure below".
+ *
+ * \anchor asfdoc_sam0_i2s_module_block_diagram
+ * \image html i2s_blocks.svg "I2S Block Diagram"
+ *
+ * This driver for I2S module provides an interface to
+ *  - initialize and control I2S module
+ *  - configure and control the I2S Clock Unit and Serializer
+ *  - transmit/receive data through I2S Serializer
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_clocks Clocks
+ *
+ * To use I2S module, the I2S bus interface clock (clk_i2s) must be enabled via
+ * Power Manager.
+ *
+ * For each I2S Clock Unit, a generic clock (gclk_i2s_n) is connnected. When I2S
+ * works in master mode the generic clock is used. It should be prepared before
+ * clock unit is used. In master mode the input generic clock will be used as
+ * MCK for SCKn and FSn generation, in addition, the MCK could be devided and
+ * output to I2S MCKn pin, as oversampling clock to external audio device.
+ *
+ * The I2S Serializer uses clock and control signal from Clock Unit to handle
+ * transfer. Select different clock unit with different configurations allows
+ * the I2S to work as master or slave, to work on non-related clocks.
+ *
+ * When using the driver with ASF, enabling the register interface is normally
+ * done by the \c init function.
+ * The gclk source for the asynchronous domain is normally configured and set
+ * through the _configuration struct_ / _init_ function. 
+ * If gclk source != 0 is used, this source has to be configured and enabled
+ * through invoking the system_gclk driver function when needed, or modifying
+ * conf_clock.h to enable it at the beginning.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_frame Audio Frame Generation
+ *
+ * Audio sample data for all channels are sent in frames, one frame can consist
+ * 1 - 8 slots where each slot can be configured to a size 8-bit, 16-bit, 24-bit
+ * or 32-bit. The audio frame synch clock is generated by the I2S Clock unit in
+ * the master/controller mode. The frame rate (or frame sync frequency) is
+ * calculated as follow:
+ *
+ * FS = SCK / number_of_slots / number_of_bits_in_slot
+ *
+ * The serial clock (SCK) source is either an external source (slave mode) or
+ * generated by the I2S clock unit (controller or master mode) using the MCK as
+ * source.
+ *
+ * SCK = MCK / sck_div
+ * \note SCK generation division value is MCKDIV in register.
+ *
+ * MCK is either an external source or generated using the gclk input from a
+ * generic clock generator.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_mode Master, Controller and Slave modes
+ *
+ * The i2s module has three modes: master, controller and slave.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_mst Master
+ * In master mode the module will control the data flow on the i2s bus and can
+ * be responsible for clock generation. The Serializers are enabled and will
+ * transmit/receive data. On a bus with only master and slave the SCK and FS
+ * clock signal will be outputted on the SCK and FS pin on the master module.
+ * MCK can optionally be outputted on the MCK pin, if there is a controller
+ * module on the bus the SCK, FS and optionally the MCK clock is sourced from
+ * the same pins. Serial data will be trancieved on the SD pin in both
+ * scenarios.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_ctl Controller
+ * In controller mode the module will generate the clock signals, but the
+ * Serializers are disabled and no data will be transmitted/received by the
+ * module in this mode. The clock signals is outputted on the SCK, FS and
+ * optionally the MCK pin.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_slv Slave
+ * In slave mode the module will use the SCK and FS clock source from the master
+ * or the controller which is received on the SCK and FS pin. The MCK can
+ * optionally be sourced externally on the MCK pin. The Serializers are enabled
+ * and will tranceive data on the SD pin. All data flow is controlled by the
+ * master.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_mode_chg Switch modes
+ * The mode switching between master, controller and slave modes are actually
+ * done by modifying the source mode of I2S pins.
+ * The source mode of I2S pins are selected by writing corresponding bits in
+ * CLKCTRLn.
+ * Since source mode switching changes the direction of pin, the mode must be
+ * changed when the I2S Clock Unit is stopped.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_data Data Stream Reception/Transmission
+ *
+ * The I2S module support several data stream formats:
+ * - I2S format
+ * - Time Division Multiplexed (TDM) format
+ * - Pulse Density Modulation (PDM) format (reception only)
+ *
+ * Basically the I2S module can send several words within each frame, it's more
+ * like TDM format. With adjust to the number of data words in a frame, the FS
+ * width, the FS to data bits delay, etc., the module is able to handle I2S
+ * compliant data stream.
+ *
+ * Also the Serializer can receive PDM format data stream, which allows the I2S
+ * module receive 1 PDM data on each SCK edge.
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_i2s I2S Stream Reception/Transmission
+ *
+ * For 2-channel I2S compliant data stream format the i2s module uses the FS
+ * line as word select (WS) signal and will send left channel data word on low
+ * WS level and right channel data word on high WS level as specified in the I2S
+ * standard. The supported word sizes are 8-, 16-, 18-, 20-, 24- and 32- bit.
+ *
+ * Thus for I2S stream, the following settings should be applied to the module:
+ *  - Data starting delay after FS transition : one SCK period
+ *  - FS width : half of frame
+ *  - Data bits adjust in word : left-adjusted
+ *  - Bit transmitting order : MSB first
+ *
+ * Following is an example for I2S application connections and waveforms. See
+ * \ref asfdoc_sam0_i2s_module_i2s_example_diagram "the figure below".
+ *
+ * \anchor asfdoc_sam0_i2s_module_i2s_example_diagram
+ * \image html i2s_example.svg "I2S Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_tdm TDM Stream Reception/Transmission
+ * In TDM format, the module sends several data words in each frame. For this
+ * data stream format most of the configurations could be adjusted:
+ *  - Main Frame related settings are as follow:
+ *   - Frame Sync (FS) options:
+ *    - the active edge of the FS (or if FS is inverted before use)
+ *    - the width of the FS
+ *   - the delay between FS to first data bit
+ *  - Data alignment in slot
+ *  - The number of slots and slot size can be adjusted, it has been mentioned
+ *    in \ref asfdoc_sam0_i2s_module_overview_frame
+ *  - The data word size is controlled by Serializer, it can be chosen among
+ *    8, 16, 18, 20, 24 and 32 bits.
+ *
+ * The general TDM waveform generation is as follow:
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_wave_diagram
+ * \image html tdm_wave.svg "TDM Waveform generation"
+ *
+ * Some other settings could also be found to set up clock, data formatting and
+ * pin mux.
+ * refer to \ref i2s_clock_unit_config "Clock Unit Configurations"
+ * and \ref i2s_serializer_config "Serializer Configurations" for more
+ * details.
+ *
+ * Following is examples for different application use cases.
+ *
+ * See \ref asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram "here" for
+ * the Time Slot Application connection and waveform example.
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram
+ * \image html tdm_timeslot_example.svg "Codec Example Diagram"
+ *
+ * See \ref asfdoc_sam0_i2s_module_tdm_codec_example_diagram "here" for the
+ * Codec Application connection and waveform example.
+ *
+ * \anchor asfdoc_sam0_i2s_module_tdm_codec_example_diagram
+ * \image html tdm_codec_example.svg "Time Slot Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_pdm PDM Reception
+ * The I2S Serializer integrates PDM reception feature, to use this feature,
+ * simply select PDM2 mode in Serializer configuration. In PDM2 mode, it assumes
+ * two microphones are input for stereo stream. The left microphone bits will
+ * be stored in lower half and right microphone bits in upper half of the data
+ * word, like in compact stereo format.
+ *
+ * See \ref asfdoc_sam0_i2s_module_pdm_example_diagram "following figure" for an
+ * example of PDM Microphones Application with both left and right channel
+ * microphone connected.
+ *
+ * \anchor asfdoc_sam0_i2s_module_pdm_example_diagram
+ * \image html pdm_example.svg "Time PDM2 Example Diagram"
+ *
+ * \subsubsection asfdoc_sam0_i2s_module_overview_data_fmt MONO and Compact Data
+ * The I2S Serializer can accept some pre-defined data format and generates
+ * the data stream in specified way.
+ *
+ * When transmitting data, the Serializer can work in MONO mode: assum input
+ * is single channel mono data on left channel and copy it to right channel
+ * automatically.
+ *
+ * Also the I2S Serializer can support compact stereo data word. The data word
+ * size of the Serializer can be set to \ref I2S_DATA_SIZE_16BIT_COMPACT
+ * "16-bit compact" or \ref I2S_DATA_SIZE_8BIT_COMPACT "8-bit compact", with
+ * these option I2S Serializer will compact left channel data and right channel
+ * data together, the left channel data will take lower bytes and right channel
+ * data take higher bytes.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_loop Loop-back Mode
+ * The I2S can be configured to loop back the Transmitter to Receiver. In this
+ * mode Serializer's input will be connected to another Serializer's output
+ * internally.
+ *
+ * \subsection asfdoc_sam0_i2s_module_overview_sleep Sleep Modes
+ * The I2S will continue to operate in any sleep mode, where the selected source
+ * clocks are running.
+ *
+ * \section asfdoc_sam0_i2s_special_considerations Special Considerations
+ *
+ * There is no special considerations for I2S module.
+ *
+ * \section asfdoc_sam0_i2s_extra_info Extra Information

+ *  - Atmel | SMART SAM C20/C21
+ *
+ * Physically, the modules are interconnected within the device as shown in the
+ * following diagram:
+ *
+ * The outline of this documentation is as follows:

+ *  - \ref asfdoc_sam0_system_pinmux_module_overview
+ *  - \ref asfdoc_sam0_system_pinmux_special_considerations

+ *
+ * \section asfdoc_sam0_system_pinmux_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_pinmux_module_overview Module Overview
+ *
+ * The SAM devices contain a number of General Purpose I/O pins, used to
+ * interface the user application logic and internal hardware peripherals to
+ * an external system. The Pin Multiplexer (PINMUX) driver provides a method
+ * of configuring the individual pin peripheral multiplexers to select
+ * alternate pin functions.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition
+ * <table>
+ *  <tr>
+ *    <th>Driver Feature Macro</th>
+ *    <th>Supported devices</th>
+ *  </tr>
+ *  <tr>
+ *    <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td>
+ *    <td>SAM L21, SAM C20/C21</td>
+ *  </tr>
+ * </table>
+ * \note The specific features are only available in the driver when the
+ * selected device supports those features.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
+ * SAM devices use two naming conventions for the I/O pins in the device; one
+ * physical and one logical. Each physical pin on a device package is assigned
+ * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
+ * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
+ * former is used to map physical pins to their physical internal device module
+ * counterparts, for simplicity the design of this driver uses the logical GPIO
+ * numbers instead.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
+ * SAM devices contain a peripheral MUX, which is individually controllable
+ * for each I/O pin of the device. The peripheral MUX allows you to select the
+ * function of a physical package pin - whether it will be controlled as a user
+ * controllable GPIO pin, or whether it will be connected internally to one of
+ * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
+ * configured in GPIO mode, other peripherals connected to the same pin will be
+ * disabled.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
+ * There are several special modes that can be selected on one or more I/O pins
+ * of the device, which alter the input and output characteristics of the pad.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
+ * The Drive Strength configures the strength of the output driver on the
+ * pad. Normally, there is a fixed current limit that each I/O pin can safely
+ * drive, however some I/O pads offer a higher drive mode which increases this
+ * limit for that I/O pin at the expense of an increased power consumption.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
+ * The Slew Rate configures the slew rate of the output driver, limiting the
+ * rate at which the pad output voltage can change with time.
+ *
+ * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
+ * The Input Sample Mode configures the input sampler buffer of the pad. By
+ * default, the input buffer is only sampled "on-demand", i.e. when the user
+ * application attempts to read from the input buffer. This mode is the most
+ * power efficient, but increases the latency of the input sample by two clock
+ * cycles of the port clock. To reduce latency, the input sampler can instead
+ * be configured to always sample the input buffer on each port clock cycle, at
+ * the expense of an increased power consumption.
+ *
+ * \subsection asfdoc_sam0_system_pinmux_module_overview_physical Physical Connection
+ *
+ * \ref asfdoc_sam0_system_pinmux_intconnections "The diagram below" shows
+ * how this module is interconnected within the device:
+ *
+ * \anchor asfdoc_sam0_system_pinmux_intconnections

+ *
+ *   pinmux -> gpio;
+ *   pad    -> pinmux;
+ *   pinmux -> peripherals;
+ * }
+ * \enddot
+ *
+ * \section asfdoc_sam0_system_pinmux_special_considerations Special Considerations
+ *
+ * The SAM port pin input sampling mode is set in groups of four physical
+ * pins; setting the sampling mode of any pin in a sub-group of eight I/O pins
+ * will configure the sampling mode of the entire sub-group.
+ *
+ * High Drive Strength output driver mode is not available on all device pins -
+ * refer to your device specific datasheet.

+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_module_overview Module Overview
+ *
+ * The System driver provides a collection of interfaces between the user
+ * application logic, and the core device functionality (such as clocks, reset
+ * cause determination, etc.) that is required for all applications. It contains
+ * a number of sub-modules that control one specific aspect of the device:
+ *
+ * - System Core (this module)
+ * - \ref asfdoc_sam0_system_clock_group "System Clock Control" (sub-module)
+ * - \ref asfdoc_sam0_system_interrupt_group "System Interrupt Control" (sub-module)
+ * - \ref asfdoc_sam0_system_pinmux_group "System Pin Multiplexer Control" (sub-module)
+ *
+ *
+ * \if DEVICE_SAML21_SYSTEM_SUPPORT
+ * \subsection asfdoc_sam0_system_module_overview_vreg_l21 Voltage Regulator
+ * The SAM device controls the voltage regulators for the core (VDDCORE) and
+ * backup (VDDBU) domains. It sets the voltage regulators according to the sleep
+ * modes, the performance level, or the user configuration.
+ *
+ * In active mode, the voltage regulator can be chosen on the fly between a LDO
+ * or a Buck converter. In standby mode, the low power voltage regulator is used
+ * to supply VDDCORE.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_bbps Battery Backup Power Switch
+ * The SAM device supports connection of a battery backup to the VBAT power pin.
+ * It includes functionality that enables automatic power switching between main
+ * power and battery backup power. This will ensure power to the backup domain,
+ * when the main battery or power source is unavailable.
+ * \endif
+ *
+ * \if DEVICE_SAMC21_SYSTEM_SUPPORT
+ * \subsection asfdoc_sam0_system_module_overview_vreg_c21 Voltage Regulator
+ * The SAM device controls the voltage regulators for the core (VDDCORE). It sets
+ * the voltage regulators according to the sleep modes.
+ *
+ * There are a selectable reference voltage and voltage dependent on the temperature
+ * which can be used by analog modules like the ADC.
+ * \endif
+ *
+ * \subsection asfdoc_sam0_system_module_overview_vref Voltage References
+ * The various analog modules within the SAM devices (such as AC, ADC, and
+ * DAC) require a voltage reference to be configured to act as a reference point
+ * for comparisons and conversions.
+ *
+ * The SAM devices contain multiple references, including an internal
+ * temperature sensor and a fixed band-gap voltage source. When enabled, the
+ * associated voltage reference can be selected within the desired peripheral
+ * where applicable.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_reset_cause System Reset Cause
+ * In some applications there may be a need to execute a different program
+ * flow based on how the device was reset. For example, if the cause of reset
+ * was the Watchdog timer (WDT), this might indicate an error in the application,
+ * and a form of error handling or error logging might be needed.
+ *
+ * For this reason, an API is provided to retrieve the cause of the last system
+ * reset, so that appropriate action can be taken.
+ *
+ * \if DEVICE_SAML21_SYSTEM_SUPPORT
+ * There are three groups of reset sources:
+ *   - Power supply reset: Resets caused by an electrical issue. It covers POR and BOD reset.
+ *   - User reset: Resets caused by the application. It covers external reset,
+ *             system reset, and watchdog reset.
+ *   - Backup reset: Resets caused by a backup mode exit condition.
+ *
+ * \subsection asfdoc_sam0_system_module_overview_performance_level Performance Level
+ * Performance level allows the user to adjust the regulator output voltage to reduce
+ * power consumption. The user can on the fly select the most suitable performance
+ * level, depending on the application demands.
+ *
+ * The SAM device can operate at two different performance levels (PL0 and PL2).
+ * When operating at PL0, the voltage applied on the full logic area is reduced
+ * by voltage scaling. This voltage scaling technique allows to reduce the active
+ * power consumption while decreasing the maximum frequency of the device. When
+ * operating at PL2, the voltage regulator supplies the highest voltage, allowing
+ * the device to run at higher clock speeds.
+ *
+ * Performance level transition is possible only when the device is in active
+ * mode. After a reset, the device starts at the lowest performance level
+ * (lowest power consumption and lowest max. frequency). The application can then
+ * switch to another performance level at any time without any stop in the code
+ * execution. As shown in \ref asfdoc_sam0_system_performance_level_transition_figure.
+ *
+ * \note When scaling down the performance level, the bus frequency should first be
+ *  scaled down in order to not exceed the maximum frequency allowed for the
+ *  low performance level.
+ *  When scaling up the performance level (e.g. from PL0 to PL2), check the performance
+ *  level status before increasing the bus frequency. It can be increased only
+ *  when the performance level transition is completed.
+ *
+ * \anchor asfdoc_sam0_system_performance_level_transition_figure
+ * \image html performance_level_transition.svg "Performance Level Transition"
+ *
+ * \subsection asfdoc_sam0_system_module_overview_power_domain Power Domain Gating
+ * Power domain gating allows power saving by reducing the voltage in logic
+ * areas in the device to a low-power supply. The feature is available in
+ * Standby sleep mode and will reduce the voltage in domains where all peripherals
+ * are idle. Internal logic will maintain its content, meaning the corresponding
+ * peripherals will not need to be reconfigured when normal operating voltage
+ * is returned. Most power domains can be in the following three states:
+ *
+ * - Active state: The power domain is powered on.
+ * - Retention state: The main voltage supply for the power domain is switched off,
+ * while maintaining a secondary low-power supply for the sequential cells. The
+ * logic context is restored when waking up.
+ * - Off state: The power domain is entirely powered off. The logic context is lost.
+ *
+ * The SAM L21 device  contains three power domains which can be controlled using
+ * power domain gating, namely PD0, PD1, and PD2. These power domains can be
+ * configured to the following cases:
+ * - Default with no sleepwalking peripherals: A power domain is automatically set
+ * to retention state in standby sleep mode if no activity require it. The application
+ * can force all power domains to remain in active state during standby sleep mode
+ * in order to accelerate wakeup time.
+ * - Default with sleepwalking peripherals: If one or more peripherals are enabled
+ * to perform sleepwalking tasks in standby sleep mode, the corresponding power
+ * domain (PDn) remains in active state as well as all inferior power domains (<PDn).
+ * - Sleepwalking with dynamic power domain gating: During standby sleep mode, a
+ * power domain (PDn) in active can wake up a superior power domain (>PDn) in order
+ * to perform a sleepwalking task. The superior power domain is then automatically
+ * set to active state. At the end of the sleepwalking task, the device can either
+ * be woken up or the superior power domain can return to retention state.
+ *
+ * Power domains can be linked to each other, it allows a power domain (PDn) to be kept
+ * in active state if the inferior power domain (PDn-1) is in active state too.
+ *
+ * \ref asfdoc_sam0_system_power_domain_overview_table illustrates the
+ * four cases to consider in standby mode.

+ *
+ * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides

+ *
+ * The following peripheral is used by this module:

+ *
+ * The following devices can use this module:
+ *  - Atmel | SMART SAM D20/D21
+ *  - Atmel | SMART SAM R21
+ *  - Atmel | SMART SAM D09/D10/D11
+ *  - Atmel | SMART SAM L21/L22
+ *  - Atmel | SMART SAM DA1
+ *  - Atmel | SMART SAM C20/C21
+ *
+ * The outline of this documentation is as follows:
+ *  - \ref asfdoc_sam0_system_interrupt_prerequisites
+ *  - \ref asfdoc_sam0_system_interrupt_module_overview
+ *  - \ref asfdoc_sam0_system_interrupt_special_considerations
+ *  - \ref asfdoc_sam0_system_interrupt_extra_info
+ *  - \ref asfdoc_sam0_system_interrupt_examples
+ *  - \ref asfdoc_sam0_system_interrupt_api_overview
+ *
+ *
+ * \section asfdoc_sam0_system_interrupt_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_system_interrupt_module_overview Module Overview
+ *
+ * The ARM&reg; Cortex&reg; M0+ core contains an interrupt and exception vector table, which
+ * can be used to configure the device's interrupt handlers; individual
+ * interrupts and exceptions can be enabled and disabled, as well as configured
+ * with a variable priority.
+ *
+ * This driver provides a set of wrappers around the core interrupt functions,
+ * to expose a simple API for the management of global and individual interrupts
+ * within the device.
+ *
+ * \subsection asfdoc_sam0_system_interrupt_module_overview_criticalsec Critical Sections
+ * In some applications it is important to ensure that no interrupts may be
+ * executed by the system whilst a critical portion of code is being run; for
+ * example, a buffer may be copied from one context to another - during which
+ * interrupts must be disabled to avoid corruption of the source buffer contents
+ * until the copy has completed. This driver provides a basic API to enter and
+ * exit nested critical sections, so that global interrupts can be kept disabled
+ * for as long as necessary to complete a critical application code section.
+ *
+ * \subsection asfdoc_sam0_system_interrupt_module_overview_softints Software Interrupts
+ * For some applications, it may be desirable to raise a module or core
+ * interrupt via software. For this reason, a set of APIs to set an interrupt or
+ * exception as pending are provided to the user application.
+ *
+ * \section asfdoc_sam0_system_interrupt_special_considerations Special Considerations
+ *
+ * Interrupts from peripherals in the SAM devices are on a per-module basis;
+ * an interrupt raised from any source within a module will cause a single,
+ * module-common handler to execute. It is the user application or driver's
+ * responsibility to de-multiplex the module-common interrupt to determine the
+ * exact interrupt cause.
+ *
+ * \section asfdoc_sam0_system_interrupt_extra_info Extra Information
+ *
+ * For extra information, see \ref asfdoc_sam0_system_interrupt_extra. This includes:
+ *  - \ref asfdoc_sam0_system_interrupt_extra_acronyms
+ *  - \ref asfdoc_sam0_system_interrupt_extra_dependencies
+ *  - \ref asfdoc_sam0_system_interrupt_extra_errata
+ *  - \ref asfdoc_sam0_system_interrupt_extra_history
+ *
+ *

+ * \ref asfdoc_sam0_system_interrupt_exqsg.

+ *
+ *
+ * \section asfdoc_sam0_tc_module_overview Module Overview
+ *
+ * The Timer/Counter (TC) module provides a set of timing and counting related
+ * functionality, such as the generation of periodic waveforms, the capturing
+ * of a periodic waveform's frequency/duty cycle, and software timekeeping for
+ * periodic operations. TC modules can be configured to use an 8-, 16-, or
+ * 32-bit counter size.
+ *
+ * This TC module for the SAM is capable of the following functions:
+ *
+ * - Generation of PWM signals
+ * - Generation of timestamps for events
+ * - General time counting
+ * - Waveform period capture
+ * - Waveform frequency capture
+ *

+ *
+ * \subsection asfdoc_sam0_tc_module_overview_func_desc Functional Description
+ * Independent of the configured counter size, each TC module can be set up
+ * in one of two different modes; capture and compare.
+ *
+ * In capture mode, the counter value is stored when a configurable event
+ * occurs. This mode can be used to generate timestamps used in event capture,
+ * or it can be used for the measurement of a periodic input signal's
+ * frequency/duty cycle.
+ *
+ * In compare mode, the counter value is compared against one or more of the
+ * configured channel compare values. When the counter value coincides with a
+ * compare value an action can be taken automatically by the module, such as
+ * generating an output event or toggling a pin when used for frequency or PWM
+ * signal generation.
+ *
+ * \note The connection of events between modules requires the use of the
+ *       \ref asfdoc_sam0_events_group "SAM Event System Driver (EVENTS)"
+ *       to route output event of one module to the input event of another.
+ *       For more information on event routing, refer to the event driver
+ *       documentation.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_tc_size Timer/Counter Size
+ * Each timer module can be configured in one of three different counter
+ * sizes; 8-, 16-, and 32-bit. The size of the counter determines the maximum
+ * value it can count to before an overflow occurs and the count is reset back
+ * to zero. \ref asfdoc_sam0_tc_count_size_vs_top "The table below" shows the
+ * maximum values for each of the possible counter sizes.
+ *
+ * \anchor asfdoc_sam0_tc_count_size_vs_top
+ * <table>
+ *  <caption>Timer Counter Sizes and Their Maximum Count Values</caption>
+ *  <tr>
+ *    <th>Counter size</th>
+ *    <th>Max. (hexadecimal)</th>
+ *    <th>Max. (decimal)</th>
+ *  </tr>
+ *  <tr>
+ *    <td>8-bit</td>
+ *    <td>0xFF</td>
+ *    <td>255</td>
+ *  </tr>
+ *  <tr>
+ *    <td>16-bit</td>
+ *    <td>0xFFFF</td>
+ *    <td>65,535</td>
+ *  </tr>
+ *  <tr>
+ *    <td>32-bit</td>
+ *    <td>0xFFFFFFFF</td>
+ *    <td>4,294,967,295</td>
+ *  </tr>
+ * </table>
+ *
+ * When using the counter in 16- or 32-bit count mode, Compare Capture
+ * register 0 (CC0) is used to store the period value when running in PWM
+ * generation match mode.
+ *
+ * When using 32-bit counter size, two 16-bit counters are chained together
+ * in a cascade formation. Except in SAM D09/D10/D11, Even numbered TC modules
+ * (e.g. TC0, TC2) can be configured as 32-bit counters. The odd numbered
+ * counters will act as slaves to the even numbered masters, and will not
+ * be reconfigurable until the master timer is disabled. The pairing of timer
+ * modules for 32-bit mode is shown in \ref asfdoc_sam0_tc_module_ms_pairs
+ * "the table below".
+ *
+ * \anchor asfdoc_sam0_tc_module_ms_pairs
+ * <table>
+ *   <caption>TC Master and Slave Module Pairings</caption>
+ *   <tr>
+ *     <th>Master TC Module</th>
+ *     <th>Slave TC Module</th>
+ *   </tr>
+ *   <tr>
+ *     <td>TC0</td>
+ *     <td>TC1</td>
+ *   </tr>
+ *   <tr>
+ *     <td>TC2</td>
+ *     <td>TC3</td>
+ *   </tr>
+ *   <tr>
+ *     <td>...</td>
+ *     <td>...</td>
+ *   </tr>
+ *   <tr>
+ *     <td>TCn-1</td>
+ *     <td>TCn</td>
+ *   </tr>
+ * </table>
+ *
+ * In SAM D09/D10/D11, odd numbered TC modules (e.g. TC1) can be configured as 32-bit
+ * counters. The even numbered(e.g. TC2) counters will act as slaves to the odd
+ * numbered masters.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_clock Clock Settings
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_selection Clock Selection
+ * Each TC peripheral is clocked asynchronously to the system clock by a GCLK
+ * (Generic Clock) channel. The GCLK channel connects to any of the GCLK
+ * generators. The GCLK generators are configured to use one of the available
+ * clock sources on the system such as internal oscillator, external crystals,
+ * etc. see the \ref asfdoc_sam0_system_clock_group "Generic Clock driver"
+ *for
+ * more information.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_prescaler Prescaler
+ * Each TC module in the SAM has its own individual clock prescaler, which
+ * can be used to divide the input clock frequency used in the counter. This
+ * prescaler only scales the clock used to provide clock pulses for the counter
+ * to count, and does not affect the digital register interface portion of
+ * the module, thus the timer registers will synchronize to the raw GCLK
+ * frequency input to the module.
+ *
+ * As a result of this, when selecting a GCLK frequency and timer prescaler
+ * value the user application should consider both the timer resolution
+ * required and the synchronization frequency, to avoid lengthy
+ * synchronization times of the module if a very slow GCLK frequency is fed
+ * into the TC module. It is preferable to use a higher module GCLK frequency
+ * as the input to the timer, and prescale this down as much as possible to
+ * obtain a suitable counter frequency in latency-sensitive applications.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_clock_reloading Reloading
+ * Timer modules also contain a configurable reload action, used when a
+ * re-trigger event occurs. Examples of a re-trigger event are the counter
+ * reaching the maximum value when counting up, or when an event from the event
+ * system tells the counter to re-trigger. The reload action determines if the
+ * prescaler should be reset, and when this should happen. The counter will
+ * always be reloaded with the value it is set to start counting from. The user
+ * can choose between three different reload actions, described in
+ * \ref asfdoc_sam0_tc_module_reload_act "the table below".
+ *
+ * \anchor asfdoc_sam0_tc_module_reload_act
+ * <table>
+ *   <caption>TC Module Reload Actions</caption>
+ *   <tr>
+ *     <th>Reload action</th>
+ *     <th>Description</th>
+ *   </tr>
+ *   <tr>
+ *     <td>\ref TC_RELOAD_ACTION_GCLK </td>
+ *     <td>Reload TC counter value on next GCLK cycle. Leave prescaler
+ *         as-is.</td>
+ *   </tr>
+ *   <tr>
+ *     <td>\ref TC_RELOAD_ACTION_PRESC </td>
+ *     <td>Reloads TC counter value on next prescaler clock. Leave prescaler
+ *         as-is.</td>
+ *   </tr>
+ *  <tr>
+ *    <td> \ref TC_RELOAD_ACTION_RESYNC </td>
+ *    <td>Reload TC counter value on next GCLK cycle. Clear prescaler to
+ *        zero.</td>
+ *  </tr>
+ * </table>
+ *
+ * The reload action to use will depend on the specific application being
+ * implemented. One example is when an external trigger for a reload occurs; if
+ * the TC uses the prescaler, the counter in the prescaler should not have a
+ * value between zero and the division factor. The TC counter and the counter
+ * in the prescaler should both start at zero. When the counter is set to
+ * re-trigger when it reaches the maximum value on the other hand, this is not the
+ * right option to use. In such a case it would be better if the prescaler is
+ * left unaltered when the re-trigger happens, letting the counter reset on the
+ * next GCLK cycle.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_compare_match Compare Match Operations
+ * In compare match operation, Compare/Capture registers are used in comparison
+ * with the counter value. When the timer's count value matches the value of a
+ * compare channel, a user defined action can be taken.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_timer Basic Timer
+ *
+ * A Basic Timer is a simple application where compare match operations is used
+ * to determine when a specific period has elapsed. In Basic Timer operations,
+ * one or more values in the module's Compare/Capture registers are used to
+ * specify the time (as a number of prescaled GCLK cycles) when an action should
+ * be taken by the microcontroller. This can be an Interrupt Service Routine
+ * (ISR), event generator via the event system, or a software flag that is
+ * polled via the user application.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg Waveform Generation
+ *
+ * Waveform generation enables the TC module to generate square waves, or if
+ * combined with an external passive low-pass filter; analog waveforms.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_pwm Waveform Generation - PWM
+ *
+ * Pulse width modulation is a form of waveform generation and a signalling
+ * technique that can be useful in many situations. When PWM mode is used,
+ * a digital pulse train with a configurable frequency and duty cycle can be
+ * generated by the TC module and output to a GPIO pin of the device.
+ *
+ * Often PWM is used to communicate a control or information parameter to an
+ * external circuit or component. Differing impedances of the source generator
+ * and sink receiver circuits is less of an issue when using PWM compared to
+ * using an analog voltage value, as noise will not generally affect the
+ * signal's integrity to a meaningful extent.
+ *
+ * \ref asfdoc_sam0_tc_module_pwm_normal_diag "The figure below" illustrates
+ * operations and different states of the counter and its output when running
+ * the counter in PWM normal mode. As can be seen, the TOP value is unchanged
+ * and is set to MAX. The compare match value is changed at several points to
+ * illustrate the resulting waveform output changes. The PWM output is set to
+ * normal (i.e. non-inverted) output mode.
+ *
+ * \anchor asfdoc_sam0_tc_module_pwm_normal_diag
+ * \image html pwm_normal_ex.svg "Example of PWM in Normal Mode, and Different Counter Operations"
+ *
+ *
+ * In \ref asfdoc_sam0_tc_module_pwm_match_diag "the figure below", the
+ * counter is set to generate PWM in Match mode. The PWM output is inverted via
+ * the appropriate configuration option in the TC driver configuration
+ * structure. In this example, the counter value is changed once, but the
+ * compare match value is kept unchanged. As can be seen, it is possible to
+ * change the TOP value when running in PWM match mode.
+ *
+ * \anchor asfdoc_sam0_tc_module_pwm_match_diag
+ * \image html pwm_match_ex.svg "Example of PWM in Match Mode, and Different Counter Operations"
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_freq Waveform Generation - Frequency
+ *
+ * Frequency Generation mode is in many ways identical to PWM
+ * generation. However, in Frequency Generation a toggle only occurs
+ * on the output when a match on a capture channels occurs. When the
+ * match is made, the timer value is reset, resulting in a variable
+ * frequency square wave with a fixed 50% duty cycle.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt Capture Operations
+ *
+ * In capture operations, any event from the event system or a pin change can
+ * trigger a capture of the counter value. This captured counter value can be
+ * used as a timestamp for the event, or it can be used in frequency and pulse
+ * width capture.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_event_capture Capture Operations - Event
+ *
+ * Event capture is a simple use of the capture functionality,
+ * designed to create timestamps for specific events. When the TC
+ * module's input capture pin is externally toggled, the current timer
+ * count value is copied into a buffered register which can then be
+ * read out by the user application.
+ *
+ * Note that when performing any capture operation, there is a risk that the
+ * counter reaches its top value (MAX) when counting up, or the bottom value
+ * (zero) when counting down, before the capture event occurs. This can distort
+ * the result, making event timestamps to appear shorter than reality; the
+ * user application should check for timer overflow when reading a capture
+ * result in order to detect this situation and perform an appropriate
+ * adjustment.
+ *
+ * Before checking for a new capture, \ref TC_STATUS_COUNT_OVERFLOW
+ * should be checked. The response to an overflow error is left to the user
+ * application, however it may be necessary to clear both the capture overflow
+ * flag and the capture flag upon each capture reading.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_pwc Capture Operations - Pulse Width
+ *
+ * Pulse Width Capture mode makes it possible to measure the pulse width and
+ * period of PWM signals. This mode uses two capture channels of the counter.
+ * This means that the counter module used for Pulse Width Capture can not be
+ * used for any other purpose. There are two modes for pulse width capture;
+ * Pulse Width Period (PWP) and Period Pulse Width (PPW). In PWP mode, capture
+ * channel 0 is used for storing the pulse width and capture channel 1 stores
+ * the observed period. While in PPW mode, the roles of the two capture channels
+ * is reversed.
+ *
+ * As in the above example it is necessary to poll on interrupt flags to see
+ * if a new capture has happened and check that a capture overflow error has
+ * not occurred.
+ *
+ * \subsection asfdoc_sam0_tc_module_overview_oneshot One-shot Mode
+ *
+ * TC modules can be configured into a one-shot mode. When configured in this
+ * manner, starting the timer will cause it to count until the next overflow
+ * or underflow condition before automatically halting, waiting to be manually
+ * triggered by the user application software or an event signal from the event
+ * system.
+ *
+ * \subsubsection asfdoc_sam0_tc_module_overview_inversion Wave Generation Output Inversion
+ *
+ * The output of the wave generation can be inverted by hardware if desired,
+ * resulting in the logically inverted value being output to the configured
+ * device GPIO pin.
+ *
+ *
+ * \section asfdoc_sam0_tc_special_considerations Special Considerations
+ *
+ * The number of capture compare registers in each TC module is dependent on
+ * the specific SAM device being used, and in some cases the counter size.
+ *
+ * The maximum amount of capture compare registers available in any SAM
+ * device is two when running in 32-bit mode and four in 8- and 16-bit modes.

+ * \section asfdoc_sam0_wdt_prerequisites Prerequisites
+ *
+ * There are no prerequisites for this module.
+ *
+ *
+ * \section asfdoc_sam0_wdt_module_overview Module Overview
+ *
+ * The Watchdog module (WDT) is designed to give an added level of safety in
+ * critical systems, to ensure a system reset is triggered in the case of a
+ * deadlock or other software malfunction that prevents normal device operation.
+ *
+ * At a basic level, the Watchdog is a system timer with a fixed period; once
+ * enabled, it will continue to count ticks of its asynchronous clock until
+ * it is periodically reset, or the timeout period is reached. In the event of a
+ * Watchdog timeout, the module will trigger a system reset identical to a pulse
+ * of the device's reset pin, resetting all peripherals to their power-on
+ * default states and restarting the application software from the reset vector.
+ *
+ * In many systems, there is an obvious upper bound to the amount of time each
+ * iteration of the main application loop can be expected to run, before a
+ * malfunction can be assumed (either due to a deadlock waiting on hardware or
+ * software, or due to other means). When the Watchdog is configured with a
+ * timeout period equal to this upper bound, a malfunction in the system will
+ * force a full system reset to allow for a graceful recovery.
+ *
+ * \subsection asfdoc_sam0_wdt_module_locked_mode Locked Mode
+ * The Watchdog configuration can be set in the device fuses and locked in
+ * hardware, so that no software changes can be made to the Watchdog
+ * configuration. Additionally, the Watchdog can be locked on in software if it
+ * is not already locked, so that the module configuration cannot be modified
+ * until a power on reset of the device.
+ *
+ * The locked configuration can be used to ensure that faulty software does not
+ * cause the Watchdog configuration to be changed, preserving the level of
+ * safety given by the module.
+ *
+ * \subsection asfdoc_sam0_wdt_module_window_mode Window Mode
+ * Just as there is a reasonable upper bound to the time the main program loop
+ * should take for each iteration, there is also in many applications a lower
+ * bound, i.e. a \a minimum time for which each loop iteration should run for
+ * under normal circumstances. To guard against a system failure resetting the
+ * Watchdog in a tight loop (or a failure in the system application causing the
+ * main loop to run faster than expected) a "Window" mode can be enabled to
+ * disallow resetting of the Watchdog counter before a certain period of time.
+ * If the Watchdog is not reset \a after the window opens but not \a before the
+ * Watchdog expires, the system will reset.
+ *
+ * \subsection asfdoc_sam0_wdt_module_early_warning Early Warning
+ * In some cases it is desirable to receive an early warning that the Watchdog is
+ * about to expire, so that some system action (such as saving any system
+ * configuration data for failure analysis purposes) can be performed before the
+ * system reset occurs. The Early Warning feature of the Watchdog module allows
+ * such a notification to be requested; after the configured early warning time
+ * (but before the expiry of the Watchdog counter) the Early Warning flag will
+ * become set, so that the user application can take an appropriate action.
+ *
+ * \note It is important to note that the purpose of the Early Warning feature
+ *       is \a not to allow the user application to reset the Watchdog; doing
+ *       so will defeat the safety the module gives to the user application.
+ *       Instead, this feature should be used purely to perform any tasks that
+ *       need to be undertaken before the system reset occurs.
+ *
+ * \subsection asfdoc_sam0_wdt_module_overview_physical Physical Connection
+ *
+ * \ref asfdoc_sam0_wdt_module_int_connections "The figure below" shows how

+# ArduinoHttpClient
+
+ArduinoHttpClient is a library to make it easier to interact with web servers from Arduino.
+
+Derived from [Adrian McEwen's HttpClient library](https://github.com/amcewen/HttpClient)
+
+## Dependencies
+
+- Requires a networking hardware and a library that provides transport specific `Client` instance, such as:
+  - [WiFi101](https://github.com/arduino-libraries/WiFi101)
+  - [Ethernet](https://github.com/arduino-libraries/Ethernet)
+  - [WiFi](https://github.com/arduino-libraries/WiFi)
+  - [GSM](https://github.com/arduino-libraries/GSM)
+
+## Usage
+
+In normal usage, handles the outgoing request and Host header.  The returned status code is parsed for you, as is the Content-Length header (if present).
+
+Because it expects an object of type Client, you can use it with any of the networking classes that derive from that.  Which means it will work with WiFiClient, EthernetClient and GSMClient.
+
+See the examples for more detail on how the library is used.

+Thank you for opening an issue on an Adafruit Arduino library repository.  To
+improve the speed of resolution please review the following guidelines and
+common troubleshooting steps below before creating the issue:
+
+- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
+  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
+  something isn't working as expected.  In many cases the problem is a common issue
+  that you will more quickly receive help from the forum community.  GitHub issues
+  are meant for known defects in the code.  If you don't know if there is a defect
+  in the code then start with troubleshooting on the forum first.
+
+- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
+  check all of the steps and commands to run have been followed.  Consult the
+  forum if you're unsure or have questions about steps in a guide/tutorial.
+
+- **For Arduino projects check these very common issues to ensure they don't apply**:
+
+  - For uploading sketches or communicating with the board make sure you're using
+    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
+    very hard to tell the difference between a data and charge cable!  Try using the
+    cable with other devices or swapping to another cable to confirm it is not
+    the problem.
+
+  - **Be sure you are supplying adequate power to the board.**  Check the specs of
+    your board and plug in an external power supply.  In many cases just
+    plugging a board into your computer is not enough to power it and other
+    peripherals.
+
+  - **Double check all soldering joints and connections.**  Flakey connections
+    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
+
+  - **Ensure you are using an official Arduino or Adafruit board.** We can't
+    guarantee a clone board will have the same functionality and work as expected
+    with this code and don't support them.
+
+If you're sure this issue is a defect in the code and checked the steps above
+please fill in the following fields to provide enough troubleshooting information.
+You may delete the guideline and text above to just leave the following details:
+
+- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
+
+- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
+  VERSION HERE**
+
+- List the steps to reproduce the problem below (if possible attach a sketch or
+  copy the sketch code in too): **LIST REPRO STEPS BELOW**

+Thank you for creating a pull request to contribute to Adafruit's GitHub code!
+Before you open the request please review the following guidelines and tips to
+help it be more easily integrated:
+
+- **Describe the scope of your change--i.e. what the change does and what parts
+  of the code were modified.**  This will help us understand any risks of integrating
+  the code.
+
+- **Describe any known limitations with your change.**  For example if the change
+  doesn't apply to a supported platform of the library please mention it.
+
+- **Please run any tests or examples that can exercise your modified code.**  We
+  strive to not break users of the code and running tests/examples helps with this
+  process.
+
+Thank you again for contributing!  We will try to test and integrate the change
+as soon as we can, but be aware we have many GitHub repositories to manage and
+can't immediately respond to every request.  There is no need to bump or check in
+on a pull request (it will clutter the discussion of the request).
+
+Also don't be worried if the request is closed or not integrated--sometimes the
+priorities of Adafruit's GitHub code (education, ease of use) might not match the
+priorities of the pull request.  Don't fret, the open source community thrives on
+forks and GitHub makes it easy to keep your changes in a forked repo.
+
+After reviewing the guidelines above you can delete this text from the pull request.

+This is a fork of JeeLab's fantastic real time clock library for Arduino.
+
+For details on using this library with an RTC module like the DS1307, PCF8523, or DS3231, see the guide at: https://learn.adafruit.com/ds1307-real-time-clock-breakout-board-kit/overview
+
+To download. click the DOWNLOADS button to the right, and rename the uncompressed folder RTClib.
+
+Place the RTClib folder in your *arduinosketchfolder*/libraries/ folder. 
+You may need to create the libraries subfolder if its your first library. Restart the IDE.

+  SD - a slightly more friendly wrapper for sdfatlib
+
+  This library aims to expose a subset of SD card functionality
+  in the form of a higher level "wrapper" object.
+
+  License: GNU General Public License V3
+          (Because sdfatlib is licensed with this.)
+
+  (C) Copyright 2010 SparkFun Electronics
+
+
+  This library provides four key benefits:
+
+     Including `SD.h` automatically creates a global
+     `SD` object which can be interacted with in a similar
+     manner to other standard global objects like `Serial` and `Ethernet`.
+
+     Boilerplate initialisation code is contained in one method named
+     `begin` and no further objects need to be created in order to access
+     the SD card.
+
+     Calls to `open` can supply a full path name including parent
+     directories which simplifies interacting with files in subdirectories.
+
+     Utility methods are provided to determine whether a file exists
+     and to create a directory hierarchy.
+
+
+  Note however that not all functionality provided by the underlying
+  sdfatlib library is exposed.
+
+*/
+
+/*
+
+  Implementation Notes
+
+  In order to handle multi-directory path traversal, functionality that
+  requires this ability is implemented as callback functions.
+
+  Individual methods call the `walkPath` function which performs the actual
+  directory traversal (swapping between two different directory/file handles
+  along the way) and at each level calls the supplied callback function.
+
+  Some types of functionality will take an action at each level (e.g. exists
+  or make directory) which others will only take an action at the bottom
+  level (e.g. open).

+
+      This is similar to `strtok()` but copies the component into the
+      supplied buffer rather than modifying the original string.
+
+
+      `buffer` needs to be PATH_COMPONENT_BUFFER_LEN in size.
+
+      `p_offset` needs to point to an integer of the offset at
+      which the previous path component finished.
+
+      Returns `true` if more components remain.

+

+
+       The implementation swaps between two different directory/file
+       handles as it traverses the directories and does not use recursion
+       in an attempt to use memory efficiently.
+
+       If a callback wishes to stop the directory traversal it should
+       return false--in this case the function will stop the traversal,
+       tidy up and return false.
+
+       If a directory path doesn't exist at some point this function will
+       also return false and not subsequently call the callback.
+

+  \mainpage Arduino SdFat Library

+  </CENTER>
+
+  \section Intro Introduction
+  The Arduino SdFat Library is a minimal implementation of FAT16 and FAT32
+  file systems on SD flash memory cards.  Standard SD and high capacity
+  SDHC cards are supported.
+
+  The SdFat only supports short 8.3 names.
+
+  The main classes in SdFat are Sd2Card, SdVolume, and SdFile.
+
+  The Sd2Card class supports access to standard SD cards and SDHC cards.  Most
+  applications will only need to call the Sd2Card::init() member function.
+
+  The SdVolume class supports FAT16 and FAT32 partitions.  Most applications
+  will only need to call the SdVolume::init() member function.
+
+  The SdFile class provides file access functions such as open(), read(),
+  remove(), write(), close() and sync(). This class supports access to the root
+  directory and subdirectories.
+
+  A number of example are provided in the SdFat/examples folder.  These were
+  developed to test SdFat and illustrate its use.
+
+  SdFat was developed for high speed data recording.  SdFat was used to implement
+  an audio record/play class, WaveRP, for the Adafruit Wave Shield.  This
+  application uses special Sd2Card calls to write to contiguous files in raw mode.
+  These functions reduce write latency so that audio can be recorded with the
+  small amount of RAM in the Arduino.
+
+  \section SDcard SD\SDHC Cards
+
+  Arduinos access SD cards using the cards SPI protocol.  PCs, Macs, and
+  most consumer devices use the 4-bit parallel SD protocol.  A card that
+  functions well on A PC or Mac may not work well on the Arduino.
+
+  Most cards have good SPI read performance but cards vary widely in SPI
+  write performance.  Write performance is limited by how efficiently the
+  card manages internal erase/remapping operations.  The Arduino cannot
+  optimize writes to reduce erase operations because of its limit RAM.
+
+  SanDisk cards generally have good write performance.  They seem to have
+  more internal RAM buffering than other cards and therefore can limit
+  the number of flash erase operations that the Arduino forces due to its
+  limited RAM.
+
+  \section Hardware Hardware Configuration
+
+  SdFat was developed using an
+  <A HREF = "http://www.adafruit.com/"> Adafruit Industries</A>
+  <A HREF = "http://www.ladyada.net/make/waveshield/"> Wave Shield</A>.
+
+  The hardware interface to the SD card should not use a resistor based level
+  shifter.  SdFat sets the SPI bus frequency to 8 MHz which results in signal
+  rise times that are too slow for the edge detectors in many newer SD card
+  controllers when resistor voltage dividers are used.
+
+  The 5 to 3.3 V level shifter for 5 V Arduinos should be IC based like the
+  74HC4050N based circuit shown in the file SdLevel.png.  The Adafruit Wave Shield
+  uses a 74AHC125N.  Gravitech sells SD and MicroSD Card Adapters based on the
+  74LCX245.
+
+  If you are using a resistor based level shifter and are having problems try
+  setting the SPI bus frequency to 4 MHz.  This can be done by using
+  card.init(SPI_HALF_SPEED) to initialize the SD card.
+
+  \section comment Bugs and Comments
+
+  If you wish to report bugs or have comments, send email to fat16lib@sbcglobal.net.
+
+  \section SdFatClass SdFat Usage
+
+  SdFat uses a slightly restricted form of short names.
+  Only printable ASCII characters are supported. No characters with code point
+  values greater than 127 are allowed.  Space is not allowed even though space
+  was allowed in the API of early versions of DOS.
+
+  Short names are limited to 8 characters followed by an optional period (.)
+  and extension of up to 3 characters.  The characters may be any combination
+  of letters and digits.  The following special characters are also allowed:
+
+  $ % ' - _ @ ~ ` ! ( ) { } ^ # &
+
+  Short names are always converted to upper case and their original case
+  value is lost.
+
+  \note
+  The Arduino Print class uses character
+  at a time writes so it was necessary to use a \link SdFile::sync() sync() \endlink
+  function to control when data is written to the SD card.
+
+  \par
+  An application which writes to a file using \link Print::print() print()\endlink,
+  \link Print::println() println() \endlink
+  or \link SdFile::write write() \endlink must call \link SdFile::sync() sync() \endlink
+  at the appropriate time to force data and directory information to be written
+  to the SD Card.  Data and directory information are also written to the SD card
+  when \link SdFile::close() close() \endlink is called.
+
+  \par
+  Applications must use care calling \link SdFile::sync() sync() \endlink
+  since 2048 bytes of I/O is required to update file and
+  directory information.  This includes writing the current data block, reading
+  the block that contains the directory entry for update, writing the directory
+  block back and reading back the current data block.
+
+  It is possible to open a file with two or more instances of SdFile.  A file may
+  be corrupted if data is written to the file by more than one instance of SdFile.
+
+  \section HowTo How to format SD Cards as FAT Volumes
+
+  You should use a freshly formatted SD card for best performance.  FAT
+  file systems become slower if many files have been created and deleted.
+  This is because the directory entry for a deleted file is marked as deleted,
+  but is not deleted.  When a new file is created, these entries must be scanned
+  before creating the file, a flaw in the FAT design.  Also files can become
+  fragmented which causes reads and writes to be slower.
+
+  Microsoft operating systems support removable media formatted with a
+  Master Boot Record, MBR, or formatted as a super floppy with a FAT Boot Sector
+  in block zero.
+
+  Microsoft operating systems expect MBR formatted removable media
+  to have only one partition. The first partition should be used.
+
+  Microsoft operating systems do not support partitioning SD flash cards.
+  If you erase an SD card with a program like KillDisk, Most versions of
+  Windows will format the card as a super floppy.
+
+  The best way to restore an SD card's format is to use SDFormatter
+  which can be downloaded from:
+
+  http://www.sdcard.org/consumers/formatter/
+
+  SDFormatter aligns flash erase boundaries with file
+  system structures which reduces write latency and file system overhead.
+
+  SDFormatter does not have an option for FAT type so it may format
+  small cards as FAT12.
+
+  After the MBR is restored by SDFormatter you may need to reformat small
+  cards that have been formatted FAT12 to force the volume type to be FAT16.
+
+  If you reformat the SD card with an OS utility, choose a cluster size that
+  will result in:
+
+  4084 < CountOfClusters && CountOfClusters < 65525
+
+  The volume will then be FAT16.
+
+  If you are formatting an SD card on OS X or Linux, be sure to use the first
+  partition. Format this partition with a cluster count in above range.

+  WiFi Web Server LED Blink
+
+  A simple web server that lets you blink an LED via the web.
+  This sketch will create a new access point (with no password).
+  It will then launch a new server and print out the IP address
+  to the Serial monitor. From there, you can open that address in a web browser
+  to turn on and off the LED on pin 13.
+
+  If the IP address of your shield is yourAddress:
+    http://yourAddress/H turns the LED on
+    http://yourAddress/L turns it off

+ This example connects to a WEP-encrypted WiFi network.
+ Then it prints the  MAC address of the WiFi shield,
+ the IP address obtained, and other network details.
+
+ If you use 40-bit WEP, you need a key that is 10 characters long,
+ and the characters must be hexadecimal (0-9 or A-F).
+ e.g.  for 40-bit, ABBADEAF01 will work, but ABBADEAF won't work
+ (too short) and ABBAISDEAF won't work (I and S are not
+ hexadecimal characters).
+
+ For 128-bit, you need a string that is 26 characters long.
+ D0D0DEADF00DABBADEAFBEADED will work because it's 26 characters,
+ all in the 0-9, A-F range.

+ MDNS WiFi Web Server
+
+ A simple web server that shows the value of the analog input pins,
+ and exposes itself on the MDNS name 'wifi101.local'.
+
+ On Linux (like Ubuntu 15.04) or OSX you can access the web page
+ on the device in a browser at 'http://wifi101.local/'.
+
+ On Windows you'll first need to install the Bonjour Printer Services
+ from:
+   https://support.apple.com/kb/dl999?locale=en_US
+ Then you can access the device in a browser at 'http://wifi101.local/'.
+
+ This example is written for a network using WPA encryption. For
+ WEP or WPA, change the WiFi.begin() call accordingly.
+
+ Circuit:
+ * WiFi shield attached
+ * Analog inputs attached to pins A0 through A5 (optional)

-# feather_sensor_lte
-
-A Particle project named feather_sensor_lte
-
-## Welcome to your project!
-
-Every new Particle project is composed of 3 important elements that you'll see have been created in your project directory for feather_sensor_lte.
-
-#### ```/src``` folder:  
-This is the source folder that contains the firmware files for your project. It should *not* be renamed. 
-Anything that is in this folder when you compile your project will be sent to our compile service and compiled into a firmware binary for the Particle device that you have targeted.
-
-If your application contains multiple files, they should all be included in the `src` folder. If your firmware depends on Particle libraries, those dependencies are specified in the `project.properties` file referenced below.
-
-#### ```.ino``` file:
-This file is the firmware that will run as the primary application on your Particle device. It contains a `setup()` and `loop()` function, and can be written in Wiring or C/C++. For more information about using the Particle firmware API to create firmware for your Particle device, refer to the [Firmware Reference](https://docs.particle.io/reference/firmware/) section of the Particle documentation.
-
-#### ```project.properties``` file:  
-This is the file that specifies the name and version number of the libraries that your project depends on. Dependencies are added automatically to your `project.properties` file when you add a library to a project using the `particle library add` command in the CLI or add a library in the Desktop IDE.
-
-## Adding additional files to your project
-
-#### Projects with multiple sources
-If you would like add additional files to your application, they should be added to the `/src` folder. All files in the `/src` folder will be sent to the Particle Cloud to produce a compiled binary.
-
-#### Projects with external libraries
-If your project includes a library that has not been registered in the Particle libraries system, you should create a new folder named `/lib/<libraryname>/src` under `/<project dir>` and add the `.h`, `.cpp` & `library.properties` files for your library there. Read the [Firmware Libraries guide](https://docs.particle.io/guide/tools-and-features/libraries/) for more details on how to develop libraries. Note that all contents of the `/lib` folder and subfolders will also be sent to the Cloud for compilation.
-
-## Compiling your project
-
-When you're ready to compile your project, make sure you have the correct Particle device target selected and run `particle compile <platform>` in the CLI or click the Compile button in the Desktop IDE. The following files in your project folder will be sent to the compile service:
-
-- Everything in the `/src` folder, including your `.ino` application file
-- The `project.properties` file for your project
-- Any libraries stored under `lib/<libraryname>/src`

- * \defgroup asfdoc_sam0_system_clock_group SAM System Clock Management Driver (SYSTEM CLOCK)
- *
- * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides an interface for the configuration
- * and management of the device's clocking related functions. This includes
- * the various clock sources, bus clocks, and generic clocks within the device,
- * with functions to manage the enabling, disabling, source selection, and
- * prescaling of clocks to various internal peripherals.
- *
- * The following peripherals are used by this module:
- *
- * - GCLK (Generic Clock Management)
- * - PM (Power Management)
- * - SYSCTRL (Clock Source Control)
- *
- * The following devices can use this module:
- *  - Atmel | SMART SAM D20/D21
- *  - Atmel | SMART SAM R21
- *  - Atmel | SMART SAM D10/D11
- *  - Atmel | SMART SAM DA0/DA1
- *
- * The outline of this documentation is as follows:
- *  - \ref asfdoc_sam0_system_clock_prerequisites
- *  - \ref asfdoc_sam0_system_clock_module_overview
- *  - \ref asfdoc_sam0_system_clock_special_considerations
- *  - \ref asfdoc_sam0_system_clock_extra_info

- *  - \ref asfdoc_sam0_system_clock_api_overview
- *
- *
- * \section asfdoc_sam0_system_clock_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_clock_module_overview Module Overview
- * The SAM devices contain a sophisticated clocking system, which is designed
- * to give the maximum flexibility to the user application. This system allows
- * a system designer to tune the performance and power consumption of the device
- * in a dynamic manner, to achieve the best trade-off between the two for a
- * particular application.
- *
- * This driver provides a set of functions for the configuration and management
- * of the various clock related functionality within the device.

- * </table>
- * \note The specific features are only available in the driver when the
- * selected device supports those features.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_clock_sources Clock Sources
- * The SAM devices have a number of master clock source modules, each of
- * which being capable of producing a stabilized output frequency, which can then
- * be fed into the various peripherals and modules within the device.
- *
- * Possible clock source modules include internal R/C oscillators, internal
- * DFLL modules, as well as external crystal oscillators and/or clock inputs.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_cpu_clock CPU / Bus Clocks
- * The CPU and AHB/APBx buses are clocked by the same physical clock source
- * (referred in this module as the Main Clock), however the APBx buses may
- * have additional prescaler division ratios set to give each peripheral bus a
- * different clock speed.
- *
- * The general main clock tree for the CPU and associated buses is shown in
- * \ref asfdoc_sam0_system_clock_module_clock_tree "the figure below".

- * \subsection asfdoc_sam0_system_clock_module_overview_clock_masking Clock Masking
- * To save power, the input clock to one or more peripherals on the AHB and APBx
- * buses can be masked away - when masked, no clock is passed into the module.
- * Disabling of clocks of unused modules will prevent all access to the masked
- * module, but will reduce the overall device power consumption.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_gclk Generic Clocks
- * Within the SAM devices there are a number of Generic Clocks; these are used to
- * provide clocks to the various peripheral clock domains in the device in a
- * standardized manner. One or more master source clocks can be selected as the
- * input clock to a Generic Clock Generator, which can prescale down the input
- * frequency to a slower rate for use in a peripheral.
- *
- * Additionally, a number of individually selectable Generic Clock Channels are
- * provided, which multiplex and gate the various generator outputs for one or
- * more peripherals within the device. This setup allows for a single common
- * generator to feed one or more channels, which can then be enabled or disabled
- * individually as required.

- * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_generators Generic Clock Generators
- * Each Generic Clock generator within the device can source its input clock
- * from one of the provided Source Clocks, and prescale the output for one or
- * more Generic Clock Channels in a one-to-many relationship. The generators
- * thus allow for several clocks to be generated of different frequencies,
- * power usages, and accuracies, which can be turned on and off individually to
- * disable the clocks to multiple peripherals as a group.
- *
- * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_channels Generic Clock Channels
- * To connect a Generic Clock Generator to a peripheral within the
- * device, a Generic Clock Channel is used. Each peripheral or
- * peripheral group has an associated Generic Clock Channel, which serves as the
- * clock input for the peripheral(s). To supply a clock to the peripheral
- * module(s), the associated channel must be connected to a running Generic
- * Clock Generator and the channel enabled.

- * The I2S consists of 2 Clock Units and 2 Serializers, which can be separately
- * configured and enabled, to provide varies functionalities as follow:
- *  - Communicate to Audio CODECs as Master or Slave, or provides clock and
- *    frame sync signals as Controller
- *  - Communicate to DAC or ADC through dedicated I2S serial interface
- *  - Communicate to multi-slot or multiple stereo DACs or ADCs, via
- *    Time Division Multiplexed (TDM) format
- *  - Reading mono or stereo MEMS microphones, using the Pulse Density
- *    Modulation (PDM) interface
- *
- * The I2S supports compact stereo data word, where left channel data bits are
- * in lower half and right channel data bits are in upper half. It reduces the
- * number of data words for stereo audio data and the DMA bandwidth.
- *
- * In master mode, the frame is configured by number of slots and slot size, and
- * allows range covering 16fs to 1024fs MCK, to provide oversampling clock to an
- * external audio CODEC or digital signal processor (DSP).
- *
- * A block diagram of the I2S can be seen in
- * \ref asfdoc_sam0_i2s_module_block_diagram "the figure below".

- *
- * This driver for I2S module provides an interface to
- *  - initialize and control I2S module
- *  - configure and control the I2S Clock Unit and Serializer
- *  - transmit/receive data through I2S Serializer
- *
- * \subsection asfdoc_sam0_i2s_module_overview_clocks Clocks
- *
- * To use I2S module, the I2S bus interface clock (clk_i2s) must be enabled via
- * Power Manager.
- *
- * For each I2S Clock Unit, a generic clock (gclk_i2s_n) is connnected. When I2S
- * works in master mode the generic clock is used. It should be prepared before
- * clock unit is used. In master mode the input generic clock will be used as
- * MCK for SCKn and FSn generation, in addition, the MCK could be devided and
- * output to I2S MCKn pin, as oversampling clock to external audio device.
- *
- * The I2S Serializer uses clock and control signal from Clock Unit to handle
- * transfer. Select different clock unit with different configurations allows
- * the I2S to work as master or slave, to work on non-related clocks.
- *
- * When using the driver with ASF, enabling the register interface is normally
- * done by the \c init function.
- * The gclk source for the asynchronous domain is normally configured and set
- * through the _configuration struct_ / _init_ function. 
- * If gclk source != 0 is used, this source has to be configured and enabled
- * through invoking the system_gclk driver function when needed, or modifying
- * conf_clock.h to enable it at the beginning.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_frame Audio Frame Generation
- *
- * Audio sample data for all channels are sent in frames, one frame can consist
- * 1 - 8 slots where each slot can be configured to a size 8-bit, 16-bit, 24-bit
- * or 32-bit. The audio frame synch clock is generated by the I2S Clock unit in
- * the master/controller mode. The frame rate (or frame sync frequency) is
- * calculated as follow:
- *
- * FS = SCK / number_of_slots / number_of_bits_in_slot
- *
- * The serial clock (SCK) source is either an external source (slave mode) or
- * generated by the I2S clock unit (controller or master mode) using the MCK as
- * source.
- *
- * SCK = MCK / sck_div
- * \note SCK generation division value is MCKDIV in register.
- *
- * MCK is either an external source or generated using the gclk input from a
- * generic clock generator.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_mode Master, Controller and Slave modes
- *
- * The i2s module has three modes: master, controller and slave.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_mst Master
- * In master mode the module will control the data flow on the i2s bus and can
- * be responsible for clock generation. The Serializers are enabled and will
- * transmit/receive data. On a bus with only master and slave the SCK and FS
- * clock signal will be outputted on the SCK and FS pin on the master module.
- * MCK can optionally be outputted on the MCK pin, if there is a controller
- * module on the bus the SCK, FS and optionally the MCK clock is sourced from
- * the same pins. Serial data will be trancieved on the SD pin in both
- * scenarios.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_ctl Controller
- * In controller mode the module will generate the clock signals, but the
- * Serializers are disabled and no data will be transmitted/received by the
- * module in this mode. The clock signals is outputted on the SCK, FS and
- * optionally the MCK pin.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_slv Slave
- * In slave mode the module will use the SCK and FS clock source from the master
- * or the controller which is received on the SCK and FS pin. The MCK can
- * optionally be sourced externally on the MCK pin. The Serializers are enabled
- * and will tranceive data on the SD pin. All data flow is controlled by the
- * master.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_chg Switch modes
- * The mode switching between master, controller and slave modes are actually
- * done by modifying the source mode of I2S pins.
- * The source mode of I2S pins are selected by writing corresponding bits in
- * CLKCTRLn.
- * Since source mode switching changes the direction of pin, the mode must be
- * changed when the I2S Clock Unit is stopped.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_data Data Stream Reception/Transmission
- *
- * The I2S module support several data stream formats:
- * - I2S format
- * - Time Division Multiplexed (TDM) format
- * - Pulse Density Modulation (PDM) format (reception only)
- *
- * Basically the I2S module can send several words within each frame, it's more
- * like TDM format. With adjust to the number of data words in a frame, the FS
- * width, the FS to data bits delay, etc., the module is able to handle I2S
- * compliant data stream.
- *
- * Also the Serializer can receive PDM format data stream, which allows the I2S
- * module receive 1 PDM data on each SCK edge.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_i2s I2S Stream Reception/Transmission
- *
- * For 2-channel I2S compliant data stream format the i2s module uses the FS
- * line as word select (WS) signal and will send left channel data word on low
- * WS level and right channel data word on high WS level as specified in the I2S
- * standard. The supported word sizes are 8-, 16-, 18-, 20-, 24- and 32- bit.
- *
- * Thus for I2S stream, the following settings should be applied to the module:
- *  - Data starting delay after FS transition : one SCK period
- *  - FS width : half of frame
- *  - Data bits adjust in word : left-adjusted
- *  - Bit transmitting order : MSB first
- *
- * Following is an example for I2S application connections and waveforms. See
- * \ref asfdoc_sam0_i2s_module_i2s_example_diagram "the figure below".
- *
- * \anchor asfdoc_sam0_i2s_module_i2s_example_diagram
- * \image html i2s_example.svg "I2S Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_tdm TDM Stream Reception/Transmission
- * In TDM format, the module sends several data words in each frame. For this
- * data stream format most of the configurations could be adjusted:
- *  - Main Frame related settings are as follow:
- *   - Frame Sync (FS) options:
- *    - the active edge of the FS (or if FS is inverted before use)
- *    - the width of the FS
- *   - the delay between FS to first data bit
- *  - Data alignment in slot
- *  - The number of slots and slot size can be adjusted, it has been mentioned
- *    in \ref asfdoc_sam0_i2s_module_overview_frame
- *  - The data word size is controlled by Serializer, it can be chosen among
- *    8, 16, 18, 20, 24 and 32 bits.
- *
- * The general TDM waveform generation is as follow:
- *
- * \anchor asfdoc_sam0_i2s_module_tdm_wave_diagram
- * \image html tdm_wave.svg "TDM Waveform generation"
- *
- * Some other settings could also be found to set up clock, data formatting and
- * pin mux.
- * refer to \ref i2s_clock_unit_config "Clock Unit Configurations"
- * and \ref i2s_serializer_config "Serializer Configurations" for more
- * details.
- *
- * Following is examples for different application use cases.
- *
- * See \ref asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram "here" for
- * the Time Slot Application connection and waveform example.
- *

- * \image html tdm_codec_example.svg "Time Slot Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_pdm PDM Reception
- * The I2S Serializer integrates PDM reception feature, to use this feature,
- * simply select PDM2 mode in Serializer configuration. In PDM2 mode, it assumes
- * two microphones are input for stereo stream. The left microphone bits will
- * be stored in lower half and right microphone bits in upper half of the data
- * word, like in compact stereo format.
- *
- * See \ref asfdoc_sam0_i2s_module_pdm_example_diagram "following figure" for an
- * example of PDM Microphones Application with both left and right channel
- * microphone connected.
- *
- * \anchor asfdoc_sam0_i2s_module_pdm_example_diagram
- * \image html pdm_example.svg "Time PDM2 Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_fmt MONO and Compact Data
- * The I2S Serializer can accept some pre-defined data format and generates
- * the data stream in specified way.
- *
- * When transmitting data, the Serializer can work in MONO mode: assum input
- * is single channel mono data on left channel and copy it to right channel
- * automatically.
- *
- * Also the I2S Serializer can support compact stereo data word. The data word
- * size of the Serializer can be set to \ref I2S_DATA_SIZE_16BIT_COMPACT
- * "16-bit compact" or \ref I2S_DATA_SIZE_8BIT_COMPACT "8-bit compact", with
- * these option I2S Serializer will compact left channel data and right channel
- * data together, the left channel data will take lower bytes and right channel
- * data take higher bytes.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_loop Loop-back Mode
- * The I2S can be configured to loop back the Transmitter to Receiver. In this
- * mode Serializer's input will be connected to another Serializer's output
- * internally.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_sleep Sleep Modes
- * The I2S will continue to operate in any sleep mode, where the selected source
- * clocks are running.
- *
- * \section asfdoc_sam0_i2s_special_considerations Special Considerations
- *
- * There is no special considerations for I2S module.

-/**
- * \defgroup asfdoc_sam0_system_pinmux_group SAM System Pin Multiplexer (SYSTEM PINMUX) Driver
- *
- * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides
- * an interface for the configuration and management of the device's physical
- * I/O Pins, to alter the direction and input/drive characteristics as well as
- * to configure the pin peripheral multiplexer selection.
- *
- * The following peripheral is used by this module:
- *  - PORT (Port I/O Management)
- *
- * The following devices can use this module:
- *  - Atmel | SMART SAM D20/D21
- *  - Atmel | SMART SAM R21
- *  - Atmel | SMART SAM D09/D10/D11
- *  - Atmel | SMART SAM L21/L22
- *  - Atmel | SMART SAM DA1
- *  - Atmel | SMART SAM C20/C21
- *
- * Physically, the modules are interconnected within the device as shown in the
- * following diagram:
- *
- * The outline of this documentation is as follows:
- *  - \ref asfdoc_sam0_system_pinmux_prerequisites
- *  - \ref asfdoc_sam0_system_pinmux_module_overview
- *  - \ref asfdoc_sam0_system_pinmux_special_considerations
- *  - \ref asfdoc_sam0_system_pinmux_extra_info

- *  - \ref asfdoc_sam0_system_pinmux_api_overview
- *
- *
- * \section asfdoc_sam0_system_pinmux_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_pinmux_module_overview Module Overview
- *
- * The SAM devices contain a number of General Purpose I/O pins, used to
- * interface the user application logic and internal hardware peripherals to
- * an external system. The Pin Multiplexer (PINMUX) driver provides a method
- * of configuring the individual pin peripheral multiplexers to select
- * alternate pin functions.
- *
- * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition
- * <table>
- *  <tr>
- *    <th>Driver Feature Macro</th>
- *    <th>Supported devices</th>
- *  </tr>
- *  <tr>
- *    <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td>
- *    <td>SAM L21, SAM C20/C21</td>
- *  </tr>
- * </table>
- * \note The specific features are only available in the driver when the
- * selected device supports those features.
- *
- * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
- * SAM devices use two naming conventions for the I/O pins in the device; one
- * physical and one logical. Each physical pin on a device package is assigned
- * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
- * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
- * former is used to map physical pins to their physical internal device module
- * counterparts, for simplicity the design of this driver uses the logical GPIO
- * numbers instead.
- *
- * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
- * SAM devices contain a peripheral MUX, which is individually controllable
- * for each I/O pin of the device. The peripheral MUX allows you to select the
- * function of a physical package pin - whether it will be controlled as a user
- * controllable GPIO pin, or whether it will be connected internally to one of
- * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
- * configured in GPIO mode, other peripherals connected to the same pin will be
- * disabled.
- *
- * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
- * There are several special modes that can be selected on one or more I/O pins
- * of the device, which alter the input and output characteristics of the pad.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
- * The Drive Strength configures the strength of the output driver on the
- * pad. Normally, there is a fixed current limit that each I/O pin can safely
- * drive, however some I/O pads offer a higher drive mode which increases this
- * limit for that I/O pin at the expense of an increased power consumption.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
- * The Slew Rate configures the slew rate of the output driver, limiting the
- * rate at which the pad output voltage can change with time.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
- * The Input Sample Mode configures the input sampler buffer of the pad. By
- * default, the input buffer is only sampled "on-demand", i.e. when the user
- * application attempts to read from the input buffer. This mode is the most
- * power efficient, but increases the latency of the input sample by two clock
- * cycles of the port clock. To reduce latency, the input sampler can instead
- * be configured to always sample the input buffer on each port clock cycle, at
- * the expense of an increased power consumption.
- *
- * \subsection asfdoc_sam0_system_pinmux_module_overview_physical Physical Connection
- *
- * \ref asfdoc_sam0_system_pinmux_intconnections "The diagram below" shows
- * how this module is interconnected within the device:
- *
- * \anchor asfdoc_sam0_system_pinmux_intconnections

- *     node [label="GPIO Module" shape=ellipse shape=ellipse style=filled fillcolor=lightgray] gpio;
- *     node [label="Other Peripheral Modules" shape=ellipse style=filled fillcolor=lightgray] peripherals;
- *   }
- *
- *   pinmux -> gpio;
- *   pad    -> pinmux;
- *   pinmux -> peripherals;
- * }
- * \enddot
- *
- * \section asfdoc_sam0_system_pinmux_special_considerations Special Considerations
- *
- * The SAM port pin input sampling mode is set in groups of four physical
- * pins; setting the sampling mode of any pin in a sub-group of eight I/O pins
- * will configure the sampling mode of the entire sub-group.
- *
- * High Drive Strength output driver mode is not available on all device pins -
- * refer to your device specific datasheet.

- * \param[in] macro  A binary operation of the form macro(data, n).  This macro
- *                   is expanded by MRECURSION with the current repetition number
- *                   and the auxiliary data argument.
- * \param[in] data   A recursive threshold, building on this to decline by times 
- *                   defined with param count.
- *
- * \return       <tt>macro(data-count+1,0) macro(data-count+2,1)...macro(data,count-1)</tt>

- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_module_overview Module Overview
- *
- * The System driver provides a collection of interfaces between the user
- * application logic, and the core device functionality (such as clocks, reset
- * cause determination, etc.) that is required for all applications. It contains
- * a number of sub-modules that control one specific aspect of the device:
- *
- * - System Core (this module)
- * - \ref asfdoc_sam0_system_clock_group "System Clock Control" (sub-module)
- * - \ref asfdoc_sam0_system_interrupt_group "System Interrupt Control" (sub-module)
- * - \ref asfdoc_sam0_system_pinmux_group "System Pin Multiplexer Control" (sub-module)
- *
- *
- * \if DEVICE_SAML21_SYSTEM_SUPPORT
- * \subsection asfdoc_sam0_system_module_overview_vreg_l21 Voltage Regulator
- * The SAM device controls the voltage regulators for the core (VDDCORE) and
- * backup (VDDBU) domains. It sets the voltage regulators according to the sleep
- * modes, the performance level, or the user configuration.
- *
- * In active mode, the voltage regulator can be chosen on the fly between a LDO
- * or a Buck converter. In standby mode, the low power voltage regulator is used
- * to supply VDDCORE.
- *
- * \subsection asfdoc_sam0_system_module_overview_bbps Battery Backup Power Switch
- * The SAM device supports connection of a battery backup to the VBAT power pin.
- * It includes functionality that enables automatic power switching between main
- * power and battery backup power. This will ensure power to the backup domain,
- * when the main battery or power source is unavailable.
- * \endif
- *
- * \if DEVICE_SAMC21_SYSTEM_SUPPORT
- * \subsection asfdoc_sam0_system_module_overview_vreg_c21 Voltage Regulator
- * The SAM device controls the voltage regulators for the core (VDDCORE). It sets
- * the voltage regulators according to the sleep modes.
- *
- * There are a selectable reference voltage and voltage dependent on the temperature
- * which can be used by analog modules like the ADC.
- * \endif
- *
- * \subsection asfdoc_sam0_system_module_overview_vref Voltage References
- * The various analog modules within the SAM devices (such as AC, ADC, and
- * DAC) require a voltage reference to be configured to act as a reference point
- * for comparisons and conversions.
- *
- * The SAM devices contain multiple references, including an internal
- * temperature sensor and a fixed band-gap voltage source. When enabled, the
- * associated voltage reference can be selected within the desired peripheral
- * where applicable.
- *
- * \subsection asfdoc_sam0_system_module_overview_reset_cause System Reset Cause
- * In some applications there may be a need to execute a different program
- * flow based on how the device was reset. For example, if the cause of reset
- * was the Watchdog timer (WDT), this might indicate an error in the application,
- * and a form of error handling or error logging might be needed.
- *
- * For this reason, an API is provided to retrieve the cause of the last system
- * reset, so that appropriate action can be taken.
- *
- * \if DEVICE_SAML21_SYSTEM_SUPPORT
- * There are three groups of reset sources:
- *   - Power supply reset: Resets caused by an electrical issue. It covers POR and BOD reset.
- *   - User reset: Resets caused by the application. It covers external reset,
- *             system reset, and watchdog reset.
- *   - Backup reset: Resets caused by a backup mode exit condition.
- *
- * \subsection asfdoc_sam0_system_module_overview_performance_level Performance Level
- * Performance level allows the user to adjust the regulator output voltage to reduce
- * power consumption. The user can on the fly select the most suitable performance
- * level, depending on the application demands.
- *
- * The SAM device can operate at two different performance levels (PL0 and PL2).
- * When operating at PL0, the voltage applied on the full logic area is reduced
- * by voltage scaling. This voltage scaling technique allows to reduce the active
- * power consumption while decreasing the maximum frequency of the device. When
- * operating at PL2, the voltage regulator supplies the highest voltage, allowing
- * the device to run at higher clock speeds.
- *
- * Performance level transition is possible only when the device is in active
- * mode. After a reset, the device starts at the lowest performance level
- * (lowest power consumption and lowest max. frequency). The application can then
- * switch to another performance level at any time without any stop in the code
- * execution. As shown in \ref asfdoc_sam0_system_performance_level_transition_figure.
- *
- * \note When scaling down the performance level, the bus frequency should first be
- *  scaled down in order to not exceed the maximum frequency allowed for the
- *  low performance level.
- *  When scaling up the performance level (e.g. from PL0 to PL2), check the performance
- *  level status before increasing the bus frequency. It can be increased only
- *  when the performance level transition is completed.
- *

- *
- * \subsection asfdoc_sam0_system_module_overview_power_domain Power Domain Gating
- * Power domain gating allows power saving by reducing the voltage in logic
- * areas in the device to a low-power supply. The feature is available in
- * Standby sleep mode and will reduce the voltage in domains where all peripherals
- * are idle. Internal logic will maintain its content, meaning the corresponding
- * peripherals will not need to be reconfigured when normal operating voltage
- * is returned. Most power domains can be in the following three states:
- *
- * - Active state: The power domain is powered on.
- * - Retention state: The main voltage supply for the power domain is switched off,
- * while maintaining a secondary low-power supply for the sequential cells. The
- * logic context is restored when waking up.
- * - Off state: The power domain is entirely powered off. The logic context is lost.
- *
- * The SAM L21 device  contains three power domains which can be controlled using
- * power domain gating, namely PD0, PD1, and PD2. These power domains can be
- * configured to the following cases:
- * - Default with no sleepwalking peripherals: A power domain is automatically set
- * to retention state in standby sleep mode if no activity require it. The application
- * can force all power domains to remain in active state during standby sleep mode
- * in order to accelerate wakeup time.
- * - Default with sleepwalking peripherals: If one or more peripherals are enabled
- * to perform sleepwalking tasks in standby sleep mode, the corresponding power
- * domain (PDn) remains in active state as well as all inferior power domains (<PDn).
- * - Sleepwalking with dynamic power domain gating: During standby sleep mode, a
- * power domain (PDn) in active can wake up a superior power domain (>PDn) in order
- * to perform a sleepwalking task. The superior power domain is then automatically
- * set to active state. At the end of the sleepwalking task, the device can either
- * be woken up or the superior power domain can return to retention state.
- *
- * Power domains can be linked to each other, it allows a power domain (PDn) to be kept
- * in active state if the inferior power domain (PDn-1) is in active state too.
- *
- * \ref asfdoc_sam0_system_power_domain_overview_table illustrates the
- * four cases to consider in standby mode.

- * \defgroup asfdoc_sam0_system_interrupt_group SAM System Interrupt (SYSTEM INTERRUPT) Driver
- *
- * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides
- * an interface for the configuration and management of internal software and
- * hardware interrupts/exceptions.
- *
- * The following peripheral is used by this module:
- *  - NVIC (Nested Vector Interrupt Controller)
- *
- * The following devices can use this module:
- *  - Atmel | SMART SAM D20/D21
- *  - Atmel | SMART SAM R21
- *  - Atmel | SMART SAM D09/D10/D11
- *  - Atmel | SMART SAM L21/L22
- *  - Atmel | SMART SAM DA1
- *  - Atmel | SMART SAM C20/C21
- *
- * The outline of this documentation is as follows:
- *  - \ref asfdoc_sam0_system_interrupt_prerequisites
- *  - \ref asfdoc_sam0_system_interrupt_module_overview
- *  - \ref asfdoc_sam0_system_interrupt_special_considerations
- *  - \ref asfdoc_sam0_system_interrupt_extra_info
- *  - \ref asfdoc_sam0_system_interrupt_examples
- *  - \ref asfdoc_sam0_system_interrupt_api_overview
- *
- *
- * \section asfdoc_sam0_system_interrupt_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_interrupt_module_overview Module Overview
- *
- * The ARM&reg; Cortex&reg; M0+ core contains an interrupt and exception vector table, which
- * can be used to configure the device's interrupt handlers; individual
- * interrupts and exceptions can be enabled and disabled, as well as configured
- * with a variable priority.
- *
- * This driver provides a set of wrappers around the core interrupt functions,
- * to expose a simple API for the management of global and individual interrupts
- * within the device.
- *
- * \subsection asfdoc_sam0_system_interrupt_module_overview_criticalsec Critical Sections
- * In some applications it is important to ensure that no interrupts may be
- * executed by the system whilst a critical portion of code is being run; for
- * example, a buffer may be copied from one context to another - during which
- * interrupts must be disabled to avoid corruption of the source buffer contents
- * until the copy has completed. This driver provides a basic API to enter and
- * exit nested critical sections, so that global interrupts can be kept disabled
- * for as long as necessary to complete a critical application code section.
- *
- * \subsection asfdoc_sam0_system_interrupt_module_overview_softints Software Interrupts
- * For some applications, it may be desirable to raise a module or core
- * interrupt via software. For this reason, a set of APIs to set an interrupt or
- * exception as pending are provided to the user application.
- *
- * \section asfdoc_sam0_system_interrupt_special_considerations Special Considerations
- *
- * Interrupts from peripherals in the SAM devices are on a per-module basis;
- * an interrupt raised from any source within a module will cause a single,
- * module-common handler to execute. It is the user application or driver's
- * responsibility to de-multiplex the module-common interrupt to determine the
- * exact interrupt cause.
- *
- * \section asfdoc_sam0_system_interrupt_extra_info Extra Information

- *  - \ref asfdoc_sam0_system_interrupt_extra_history

- * \section asfdoc_sam0_tc_module_overview Module Overview
- *
- * The Timer/Counter (TC) module provides a set of timing and counting related
- * functionality, such as the generation of periodic waveforms, the capturing
- * of a periodic waveform's frequency/duty cycle, and software timekeeping for
- * periodic operations. TC modules can be configured to use an 8-, 16-, or
- * 32-bit counter size.
- *
- * This TC module for the SAM is capable of the following functions:
- *
- * - Generation of PWM signals
- * - Generation of timestamps for events
- * - General time counting
- * - Waveform period capture
- * - Waveform frequency capture
- *
- * \ref asfdoc_sam0_tc_block_diagram "The diagram below" shows the overview
- * of the TC module design.

- *
- * \subsection asfdoc_sam0_tc_module_overview_func_desc Functional Description
- * Independent of the configured counter size, each TC module can be set up
- * in one of two different modes; capture and compare.
- *
- * In capture mode, the counter value is stored when a configurable event
- * occurs. This mode can be used to generate timestamps used in event capture,
- * or it can be used for the measurement of a periodic input signal's
- * frequency/duty cycle.
- *
- * In compare mode, the counter value is compared against one or more of the
- * configured channel compare values. When the counter value coincides with a
- * compare value an action can be taken automatically by the module, such as
- * generating an output event or toggling a pin when used for frequency or PWM
- * signal generation.
- *
- * \note The connection of events between modules requires the use of the
- *       \ref asfdoc_sam0_events_group "SAM Event System Driver (EVENTS)"
- *       to route output event of one module to the input event of another.
- *       For more information on event routing, refer to the event driver
- *       documentation.
- *
- * \subsection asfdoc_sam0_tc_module_overview_tc_size Timer/Counter Size
- * Each timer module can be configured in one of three different counter
- * sizes; 8-, 16-, and 32-bit. The size of the counter determines the maximum
- * value it can count to before an overflow occurs and the count is reset back
- * to zero. \ref asfdoc_sam0_tc_count_size_vs_top "The table below" shows the
- * maximum values for each of the possible counter sizes.
- *
- * \anchor asfdoc_sam0_tc_count_size_vs_top
- * <table>
- *  <caption>Timer Counter Sizes and Their Maximum Count Values</caption>
- *  <tr>
- *    <th>Counter size</th>
- *    <th>Max. (hexadecimal)</th>
- *    <th>Max. (decimal)</th>
- *  </tr>
- *  <tr>
- *    <td>8-bit</td>
- *    <td>0xFF</td>
- *    <td>255</td>
- *  </tr>
- *  <tr>
- *    <td>16-bit</td>
- *    <td>0xFFFF</td>
- *    <td>65,535</td>
- *  </tr>
- *  <tr>
- *    <td>32-bit</td>
- *    <td>0xFFFFFFFF</td>
- *    <td>4,294,967,295</td>
- *  </tr>
- * </table>
- *
- * When using the counter in 16- or 32-bit count mode, Compare Capture
- * register 0 (CC0) is used to store the period value when running in PWM
- * generation match mode.
- *
- * When using 32-bit counter size, two 16-bit counters are chained together
- * in a cascade formation. Except in SAM D09/D10/D11, Even numbered TC modules
- * (e.g. TC0, TC2) can be configured as 32-bit counters. The odd numbered
- * counters will act as slaves to the even numbered masters, and will not
- * be reconfigurable until the master timer is disabled. The pairing of timer
- * modules for 32-bit mode is shown in \ref asfdoc_sam0_tc_module_ms_pairs
- * "the table below".
- *
- * \anchor asfdoc_sam0_tc_module_ms_pairs
- * <table>
- *   <caption>TC Master and Slave Module Pairings</caption>
- *   <tr>
- *     <th>Master TC Module</th>
- *     <th>Slave TC Module</th>
- *   </tr>
- *   <tr>
- *     <td>TC0</td>
- *     <td>TC1</td>
- *   </tr>
- *   <tr>
- *     <td>TC2</td>
- *     <td>TC3</td>
- *   </tr>
- *   <tr>
- *     <td>...</td>
- *     <td>...</td>
- *   </tr>
- *   <tr>
- *     <td>TCn-1</td>
- *     <td>TCn</td>
- *   </tr>
- * </table>
- *
- * In SAM D09/D10/D11, odd numbered TC modules (e.g. TC1) can be configured as 32-bit
- * counters. The even numbered(e.g. TC2) counters will act as slaves to the odd
- * numbered masters.
- *
- * \subsection asfdoc_sam0_tc_module_overview_clock Clock Settings
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_selection Clock Selection
- * Each TC peripheral is clocked asynchronously to the system clock by a GCLK
- * (Generic Clock) channel. The GCLK channel connects to any of the GCLK
- * generators. The GCLK generators are configured to use one of the available
- * clock sources on the system such as internal oscillator, external crystals,
- * etc. see the \ref asfdoc_sam0_system_clock_group "Generic Clock driver"
- *for
- * more information.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_prescaler Prescaler
- * Each TC module in the SAM has its own individual clock prescaler, which
- * can be used to divide the input clock frequency used in the counter. This
- * prescaler only scales the clock used to provide clock pulses for the counter
- * to count, and does not affect the digital register interface portion of
- * the module, thus the timer registers will synchronize to the raw GCLK
- * frequency input to the module.
- *
- * As a result of this, when selecting a GCLK frequency and timer prescaler
- * value the user application should consider both the timer resolution
- * required and the synchronization frequency, to avoid lengthy
- * synchronization times of the module if a very slow GCLK frequency is fed
- * into the TC module. It is preferable to use a higher module GCLK frequency
- * as the input to the timer, and prescale this down as much as possible to
- * obtain a suitable counter frequency in latency-sensitive applications.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_reloading Reloading
- * Timer modules also contain a configurable reload action, used when a
- * re-trigger event occurs. Examples of a re-trigger event are the counter
- * reaching the maximum value when counting up, or when an event from the event
- * system tells the counter to re-trigger. The reload action determines if the
- * prescaler should be reset, and when this should happen. The counter will
- * always be reloaded with the value it is set to start counting from. The user
- * can choose between three different reload actions, described in
- * \ref asfdoc_sam0_tc_module_reload_act "the table below".
- *
- * \anchor asfdoc_sam0_tc_module_reload_act
- * <table>
- *   <caption>TC Module Reload Actions</caption>
- *   <tr>
- *     <th>Reload action</th>
- *     <th>Description</th>
- *   </tr>
- *   <tr>
- *     <td>\ref TC_RELOAD_ACTION_GCLK </td>
- *     <td>Reload TC counter value on next GCLK cycle. Leave prescaler
- *         as-is.</td>
- *   </tr>
- *   <tr>
- *     <td>\ref TC_RELOAD_ACTION_PRESC </td>
- *     <td>Reloads TC counter value on next prescaler clock. Leave prescaler
- *         as-is.</td>
- *   </tr>
- *  <tr>
- *    <td> \ref TC_RELOAD_ACTION_RESYNC </td>
- *    <td>Reload TC counter value on next GCLK cycle. Clear prescaler to
- *        zero.</td>
- *  </tr>
- * </table>
- *
- * The reload action to use will depend on the specific application being
- * implemented. One example is when an external trigger for a reload occurs; if
- * the TC uses the prescaler, the counter in the prescaler should not have a
- * value between zero and the division factor. The TC counter and the counter
- * in the prescaler should both start at zero. When the counter is set to
- * re-trigger when it reaches the maximum value on the other hand, this is not the
- * right option to use. In such a case it would be better if the prescaler is
- * left unaltered when the re-trigger happens, letting the counter reset on the
- * next GCLK cycle.
- *
- * \subsection asfdoc_sam0_tc_module_overview_compare_match Compare Match Operations
- * In compare match operation, Compare/Capture registers are used in comparison
- * with the counter value. When the timer's count value matches the value of a
- * compare channel, a user defined action can be taken.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_timer Basic Timer
- *
- * A Basic Timer is a simple application where compare match operations is used
- * to determine when a specific period has elapsed. In Basic Timer operations,
- * one or more values in the module's Compare/Capture registers are used to
- * specify the time (as a number of prescaled GCLK cycles) when an action should
- * be taken by the microcontroller. This can be an Interrupt Service Routine
- * (ISR), event generator via the event system, or a software flag that is
- * polled via the user application.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg Waveform Generation
- *
- * Waveform generation enables the TC module to generate square waves, or if
- * combined with an external passive low-pass filter; analog waveforms.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_pwm Waveform Generation - PWM
- *
- * Pulse width modulation is a form of waveform generation and a signalling
- * technique that can be useful in many situations. When PWM mode is used,
- * a digital pulse train with a configurable frequency and duty cycle can be
- * generated by the TC module and output to a GPIO pin of the device.
- *
- * Often PWM is used to communicate a control or information parameter to an
- * external circuit or component. Differing impedances of the source generator
- * and sink receiver circuits is less of an issue when using PWM compared to
- * using an analog voltage value, as noise will not generally affect the
- * signal's integrity to a meaningful extent.
- *
- * \ref asfdoc_sam0_tc_module_pwm_normal_diag "The figure below" illustrates
- * operations and different states of the counter and its output when running
- * the counter in PWM normal mode. As can be seen, the TOP value is unchanged
- * and is set to MAX. The compare match value is changed at several points to
- * illustrate the resulting waveform output changes. The PWM output is set to
- * normal (i.e. non-inverted) output mode.
- *
- * \anchor asfdoc_sam0_tc_module_pwm_normal_diag
- * \image html pwm_normal_ex.svg "Example of PWM in Normal Mode, and Different Counter Operations"
- *
- *
- * In \ref asfdoc_sam0_tc_module_pwm_match_diag "the figure below", the
- * counter is set to generate PWM in Match mode. The PWM output is inverted via
- * the appropriate configuration option in the TC driver configuration
- * structure. In this example, the counter value is changed once, but the
- * compare match value is kept unchanged. As can be seen, it is possible to
- * change the TOP value when running in PWM match mode.
- *
- * \anchor asfdoc_sam0_tc_module_pwm_match_diag
- * \image html pwm_match_ex.svg "Example of PWM in Match Mode, and Different Counter Operations"
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_freq Waveform Generation - Frequency
- *
- * Frequency Generation mode is in many ways identical to PWM
- * generation. However, in Frequency Generation a toggle only occurs
- * on the output when a match on a capture channels occurs. When the
- * match is made, the timer value is reset, resulting in a variable
- * frequency square wave with a fixed 50% duty cycle.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt Capture Operations
- *
- * In capture operations, any event from the event system or a pin change can
- * trigger a capture of the counter value. This captured counter value can be
- * used as a timestamp for the event, or it can be used in frequency and pulse
- * width capture.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_event_capture Capture Operations - Event
- *
- * Event capture is a simple use of the capture functionality,
- * designed to create timestamps for specific events. When the TC
- * module's input capture pin is externally toggled, the current timer
- * count value is copied into a buffered register which can then be
- * read out by the user application.
- *
- * Note that when performing any capture operation, there is a risk that the
- * counter reaches its top value (MAX) when counting up, or the bottom value
- * (zero) when counting down, before the capture event occurs. This can distort
- * the result, making event timestamps to appear shorter than reality; the
- * user application should check for timer overflow when reading a capture
- * result in order to detect this situation and perform an appropriate
- * adjustment.
- *
- * Before checking for a new capture, \ref TC_STATUS_COUNT_OVERFLOW
- * should be checked. The response to an overflow error is left to the user
- * application, however it may be necessary to clear both the capture overflow
- * flag and the capture flag upon each capture reading.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_pwc Capture Operations - Pulse Width
- *
- * Pulse Width Capture mode makes it possible to measure the pulse width and
- * period of PWM signals. This mode uses two capture channels of the counter.
- * This means that the counter module used for Pulse Width Capture can not be
- * used for any other purpose. There are two modes for pulse width capture;
- * Pulse Width Period (PWP) and Period Pulse Width (PPW). In PWP mode, capture
- * channel 0 is used for storing the pulse width and capture channel 1 stores
- * the observed period. While in PPW mode, the roles of the two capture channels
- * is reversed.
- *
- * As in the above example it is necessary to poll on interrupt flags to see
- * if a new capture has happened and check that a capture overflow error has
- * not occurred.
- *
- * \subsection asfdoc_sam0_tc_module_overview_oneshot One-shot Mode
- *
- * TC modules can be configured into a one-shot mode. When configured in this
- * manner, starting the timer will cause it to count until the next overflow
- * or underflow condition before automatically halting, waiting to be manually
- * triggered by the user application software or an event signal from the event
- * system.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_inversion Wave Generation Output Inversion
- *
- * The output of the wave generation can be inverted by hardware if desired,
- * resulting in the logically inverted value being output to the configured
- * device GPIO pin.
- *
- *
- * \section asfdoc_sam0_tc_special_considerations Special Considerations
- *
- * The number of capture compare registers in each TC module is dependent on
- * the specific SAM device being used, and in some cases the counter size.
- *
- * The maximum amount of capture compare registers available in any SAM
- * device is two when running in 32-bit mode and four in 8- and 16-bit modes.

- *
- *
- * \section asfdoc_sam0_wdt_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_wdt_module_overview Module Overview
- *
- * The Watchdog module (WDT) is designed to give an added level of safety in
- * critical systems, to ensure a system reset is triggered in the case of a
- * deadlock or other software malfunction that prevents normal device operation.
- *
- * At a basic level, the Watchdog is a system timer with a fixed period; once
- * enabled, it will continue to count ticks of its asynchronous clock until
- * it is periodically reset, or the timeout period is reached. In the event of a
- * Watchdog timeout, the module will trigger a system reset identical to a pulse
- * of the device's reset pin, resetting all peripherals to their power-on
- * default states and restarting the application software from the reset vector.
- *
- * In many systems, there is an obvious upper bound to the amount of time each
- * iteration of the main application loop can be expected to run, before a
- * malfunction can be assumed (either due to a deadlock waiting on hardware or
- * software, or due to other means). When the Watchdog is configured with a
- * timeout period equal to this upper bound, a malfunction in the system will
- * force a full system reset to allow for a graceful recovery.
- *
- * \subsection asfdoc_sam0_wdt_module_locked_mode Locked Mode
- * The Watchdog configuration can be set in the device fuses and locked in
- * hardware, so that no software changes can be made to the Watchdog
- * configuration. Additionally, the Watchdog can be locked on in software if it
- * is not already locked, so that the module configuration cannot be modified
- * until a power on reset of the device.
- *
- * The locked configuration can be used to ensure that faulty software does not
- * cause the Watchdog configuration to be changed, preserving the level of
- * safety given by the module.
- *
- * \subsection asfdoc_sam0_wdt_module_window_mode Window Mode
- * Just as there is a reasonable upper bound to the time the main program loop
- * should take for each iteration, there is also in many applications a lower
- * bound, i.e. a \a minimum time for which each loop iteration should run for
- * under normal circumstances. To guard against a system failure resetting the
- * Watchdog in a tight loop (or a failure in the system application causing the
- * main loop to run faster than expected) a "Window" mode can be enabled to
- * disallow resetting of the Watchdog counter before a certain period of time.
- * If the Watchdog is not reset \a after the window opens but not \a before the
- * Watchdog expires, the system will reset.
- *
- * \subsection asfdoc_sam0_wdt_module_early_warning Early Warning
- * In some cases it is desirable to receive an early warning that the Watchdog is
- * about to expire, so that some system action (such as saving any system
- * configuration data for failure analysis purposes) can be performed before the
- * system reset occurs. The Early Warning feature of the Watchdog module allows
- * such a notification to be requested; after the configured early warning time
- * (but before the expiry of the Watchdog counter) the Early Warning flag will
- * become set, so that the user application can take an appropriate action.
- *
- * \note It is important to note that the purpose of the Early Warning feature
- *       is \a not to allow the user application to reset the Watchdog; doing
- *       so will defeat the safety the module gives to the user application.
- *       Instead, this feature should be used purely to perform any tasks that
- *       need to be undertaken before the system reset occurs.
- *
- * \subsection asfdoc_sam0_wdt_module_overview_physical Physical Connection
- *
- * \ref asfdoc_sam0_wdt_module_int_connections "The figure below" shows how
- * this module is interconnected within the device.
- *
- * \anchor asfdoc_sam0_wdt_module_int_connections
- * \dot
- * digraph overview {
- *   rankdir=LR;

- *     node [label="<f0> WDT | <f1> Watchdog Counter" shape=record] wdt_module;
- *     node [label="System Reset Logic" shape=ellipse style=filled fillcolor=lightgray] sys_reset;

- *
- *   wdt_clock     -> wdt_module:f1;
- *   wdt_module:f1 -> sys_reset;
- * }
- * \enddot
- *
- * \note Watchdog Counter of SAM L21/L22 is \a not provided by GCLK, but it uses an
- *       internal 1KHz OSCULP32K output clock.
- *
- * \section asfdoc_sam0_wdt_special_considerations Special Considerations
- *
- * On some devices the Watchdog configuration can be fused to be always on in
- * a particular configuration; if this mode is enabled the Watchdog is not
- * software configurable and can have its count reset and early warning state
- * checked/cleared only.

-    // On AVR, the WTD timeout is configured in one register and then an
-    // interrupt can optionally be enabled to handle the timeout in code
-    // (as in waking from sleep) vs resetting the chip.  Easy.
-    // On SAMD, when the WDT fires, that's it, the chip's getting reset.
-    // Instead, it has an "early warning interrupt" with a different set
-    // interval prior to the reset.  For equivalent behavior to the AVR
-    // library, this requires a slightly different configuration depending
-    // whether we're coming from the sleep() function (which needs the
-    // interrupt), or just enable() (no interrupt, we want the chip reset
-    // unless the WDT is cleared first).  In the sleep case, 'windowed'
-    // mode is used in order to allow access to the longest available
-    // sleep interval (about 16 sec); the WDT 'period' (when a reset
-    // occurs) follows this and is always just set to the max, since the
-    // interrupt will trigger first.  In the enable case, windowed mode
-    // is not used, the WDT period is set and that's that.
-    // The 'isForSleep' argument determines which behavior is used;
-    // this isn't present in the AVR code, just here.  It defaults to
-    // 'false' so existing Arduino code works as normal, while the sleep()

-# ArduinoHttpClient
-
-ArduinoHttpClient is a library to make it easier to interact with web servers from Arduino.
-
-Derived from [Adrian McEwen's HttpClient library](https://github.com/amcewen/HttpClient)
-
-## Dependencies
-
-- Requires a networking hardware and a library that provides transport specific `Client` instance, such as:
-  - [WiFi101](https://github.com/arduino-libraries/WiFi101)
-  - [Ethernet](https://github.com/arduino-libraries/Ethernet)
-  - [WiFi](https://github.com/arduino-libraries/WiFi)
-  - [GSM](https://github.com/arduino-libraries/GSM)
-
-## Usage
-
-In normal usage, handles the outgoing request and Host header.  The returned status code is parsed for you, as is the Content-Length header (if present).
-
-Because it expects an object of type Client, you can use it with any of the networking classes that derive from that.  Which means it will work with WiFiClient, EthernetClient and GSMClient.
-
-See the examples for more detail on how the library is used.

-/* HueBlink example for ArduinoHttpClient library
-
-   Uses ArduinoHttpClient library to control Philips Hue
-   For more on Hue developer API see http://developer.meethue.com
-
-  To control a light, the Hue expects a HTTP PUT request to:
-
-  http://hue.hub.address/api/hueUserName/lights/lightNumber/state
-
-  The body of the PUT request looks like this:
-  {"on": true} or {"on":false}
-
-  This example  shows how to concatenate Strings to assemble the
-  PUT request and the body of the request.

-Thank you for opening an issue on an Adafruit Arduino library repository.  To
-improve the speed of resolution please review the following guidelines and
-common troubleshooting steps below before creating the issue:
-
-- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
-  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
-  something isn't working as expected.  In many cases the problem is a common issue
-  that you will more quickly receive help from the forum community.  GitHub issues
-  are meant for known defects in the code.  If you don't know if there is a defect
-  in the code then start with troubleshooting on the forum first.
-
-- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
-  check all of the steps and commands to run have been followed.  Consult the
-  forum if you're unsure or have questions about steps in a guide/tutorial.
-
-- **For Arduino projects check these very common issues to ensure they don't apply**:
-
-  - For uploading sketches or communicating with the board make sure you're using
-    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
-    very hard to tell the difference between a data and charge cable!  Try using the
-    cable with other devices or swapping to another cable to confirm it is not
-    the problem.
-
-  - **Be sure you are supplying adequate power to the board.**  Check the specs of
-    your board and plug in an external power supply.  In many cases just
-    plugging a board into your computer is not enough to power it and other
-    peripherals.
-
-  - **Double check all soldering joints and connections.**  Flakey connections
-    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
-
-  - **Ensure you are using an official Arduino or Adafruit board.** We can't
-    guarantee a clone board will have the same functionality and work as expected
-    with this code and don't support them.
-
-If you're sure this issue is a defect in the code and checked the steps above
-please fill in the following fields to provide enough troubleshooting information.
-You may delete the guideline and text above to just leave the following details:
-
-- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
-
-- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
-  VERSION HERE**
-
-- List the steps to reproduce the problem below (if possible attach a sketch or
-  copy the sketch code in too): **LIST REPRO STEPS BELOW**

-Thank you for creating a pull request to contribute to Adafruit's GitHub code!
-Before you open the request please review the following guidelines and tips to
-help it be more easily integrated:
-
-- **Describe the scope of your change--i.e. what the change does and what parts
-  of the code were modified.**  This will help us understand any risks of integrating
-  the code.
-
-- **Describe any known limitations with your change.**  For example if the change
-  doesn't apply to a supported platform of the library please mention it.
-
-- **Please run any tests or examples that can exercise your modified code.**  We
-  strive to not break users of the code and running tests/examples helps with this
-  process.
-
-Thank you again for contributing!  We will try to test and integrate the change
-as soon as we can, but be aware we have many GitHub repositories to manage and
-can't immediately respond to every request.  There is no need to bump or check in
-on a pull request (it will clutter the discussion of the request).
-
-Also don't be worried if the request is closed or not integrated--sometimes the
-priorities of Adafruit's GitHub code (education, ease of use) might not match the
-priorities of the pull request.  Don't fret, the open source community thrives on
-forks and GitHub makes it easy to keep your changes in a forked repo.

-Thank you for opening an issue on an Adafruit Arduino library repository.  To
-improve the speed of resolution please review the following guidelines and
-common troubleshooting steps below before creating the issue:
-
-- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
-  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
-  something isn't working as expected.  In many cases the problem is a common issue
-  that you will more quickly receive help from the forum community.  GitHub issues
-  are meant for known defects in the code.  If you don't know if there is a defect
-  in the code then start with troubleshooting on the forum first.
-
-- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
-  check all of the steps and commands to run have been followed.  Consult the
-  forum if you're unsure or have questions about steps in a guide/tutorial.
-
-- **For Arduino projects check these very common issues to ensure they don't apply**:
-
-  - For uploading sketches or communicating with the board make sure you're using
-    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
-    very hard to tell the difference between a data and charge cable!  Try using the
-    cable with other devices or swapping to another cable to confirm it is not
-    the problem.
-
-  - **Be sure you are supplying adequate power to the board.**  Check the specs of
-    your board and plug in an external power supply.  In many cases just
-    plugging a board into your computer is not enough to power it and other
-    peripherals.
-
-  - **Double check all soldering joints and connections.**  Flakey connections
-    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
-
-  - **Ensure you are using an official Arduino or Adafruit board.** We can't
-    guarantee a clone board will have the same functionality and work as expected
-    with this code and don't support them.
-
-If you're sure this issue is a defect in the code and checked the steps above
-please fill in the following fields to provide enough troubleshooting information.
-You may delete the guideline and text above to just leave the following details:
-
-- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
-
-- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
-  VERSION HERE**
-
-- List the steps to reproduce the problem below (if possible attach a sketch or
-  copy the sketch code in too): **LIST REPRO STEPS BELOW**

-Thank you for creating a pull request to contribute to Adafruit's GitHub code!
-Before you open the request please review the following guidelines and tips to
-help it be more easily integrated:
-
-- **Describe the scope of your change--i.e. what the change does and what parts
-  of the code were modified.**  This will help us understand any risks of integrating
-  the code.
-
-- **Describe any known limitations with your change.**  For example if the change
-  doesn't apply to a supported platform of the library please mention it.
-
-- **Please run any tests or examples that can exercise your modified code.**  We
-  strive to not break users of the code and running tests/examples helps with this
-  process.
-
-Thank you again for contributing!  We will try to test and integrate the change
-as soon as we can, but be aware we have many GitHub repositories to manage and
-can't immediately respond to every request.  There is no need to bump or check in
-on a pull request (it will clutter the discussion of the request).
-
-Also don't be worried if the request is closed or not integrated--sometimes the
-priorities of Adafruit's GitHub code (education, ease of use) might not match the
-priorities of the pull request.  Don't fret, the open source community thrives on
-forks and GitHub makes it easy to keep your changes in a forked repo.
-
-After reviewing the guidelines above you can delete this text from the pull request.

-  WiFi Web Server LED Blink
-
-  A simple web server that lets you blink an LED via the web.
-  This sketch will create a new access point (with no password).
-  It will then launch a new server and print out the IP address
-  to the Serial monitor. From there, you can open that address in a web browser
-  to turn on and off the LED on pin 13.
-
-  If the IP address of your shield is yourAddress:
-    http://yourAddress/H turns the LED on
-    http://yourAddress/L turns it off
-

- This example connects to a WEP-encrypted WiFi network.
- Then it prints the  MAC address of the WiFi shield,
- the IP address obtained, and other network details.
-
- If you use 40-bit WEP, you need a key that is 10 characters long,
- and the characters must be hexadecimal (0-9 or A-F).
- e.g.  for 40-bit, ABBADEAF01 will work, but ABBADEAF won't work
- (too short) and ABBAISDEAF won't work (I and S are not
- hexadecimal characters).
-
- For 128-bit, you need a string that is 26 characters long.
- D0D0DEADF00DABBADEAFBEADED will work because it's 26 characters,
- all in the 0-9, A-F range.

- MDNS WiFi Web Server
-
- A simple web server that shows the value of the analog input pins,
- and exposes itself on the MDNS name 'wifi101.local'.
-
- On Linux (like Ubuntu 15.04) or OSX you can access the web page
- on the device in a browser at 'http://wifi101.local/'.
-
- On Windows you'll first need to install the Bonjour Printer Services
- from:
-   https://support.apple.com/kb/dl999?locale=en_US
- Then you can access the device in a browser at 'http://wifi101.local/'.
-
- This example is written for a network using WPA encryption. For
- WEP or WPA, change the WiFi.begin() call accordingly.
-
- Circuit:
- * WiFi shield attached
- * Analog inputs attached to pins A0 through A5 (optional)

- * \section asfdoc_sam0_system_clock_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_clock_module_overview Module Overview
- * The SAM devices contain a sophisticated clocking system, which is designed
- * to give the maximum flexibility to the user application. This system allows
- * a system designer to tune the performance and power consumption of the device
- * in a dynamic manner, to achieve the best trade-off between the two for a
- * particular application.
- *
- * This driver provides a set of functions for the configuration and management
- * of the various clock related functionality within the device.

- *		<td>FEATURE_SYSTEM_CLOCK_DPLL</td>
- *		<td>SAMD21, SAMR21, SAMD10, SAMD11, SAMDAx</td>
- *	</tr>
- * </table>
- * \note The specific features are only available in the driver when the
- * selected device supports those features.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_clock_sources Clock Sources
- * The SAM devices have a number of master clock source modules, each of
- * which being capable of producing a stabilized output frequency, which can then
- * be fed into the various peripherals and modules within the device.
- *
- * Possible clock source modules include internal R/C oscillators, internal
- * DFLL modules, as well as external crystal oscillators and/or clock inputs.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_cpu_clock CPU / Bus Clocks
- * The CPU and AHB/APBx buses are clocked by the same physical clock source
- * (referred in this module as the Main Clock), however the APBx buses may
- * have additional prescaler division ratios set to give each peripheral bus a
- * different clock speed.
- *
- * The general main clock tree for the CPU and associated buses is shown in
- * \ref asfdoc_sam0_system_clock_module_clock_tree "the figure below".

- *
- * \subsection asfdoc_sam0_system_clock_module_overview_clock_masking Clock Masking
- * To save power, the input clock to one or more peripherals on the AHB and APBx
- * buses can be masked away - when masked, no clock is passed into the module.
- * Disabling of clocks of unused modules will prevent all access to the masked
- * module, but will reduce the overall device power consumption.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_gclk Generic Clocks
- * Within the SAM devices there are a number of Generic Clocks; these are used to
- * provide clocks to the various peripheral clock domains in the device in a
- * standardized manner. One or more master source clocks can be selected as the
- * input clock to a Generic Clock Generator, which can prescale down the input
- * frequency to a slower rate for use in a peripheral.
- *
- * Additionally, a number of individually selectable Generic Clock Channels are
- * provided, which multiplex and gate the various generator outputs for one or
- * more peripherals within the device. This setup allows for a single common
- * generator to feed one or more channels, which can then be enabled or disabled
- * individually as required.

- * }
- * \enddot
- *
- * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_generators Generic Clock Generators
- * Each Generic Clock generator within the device can source its input clock
- * from one of the provided Source Clocks, and prescale the output for one or
- * more Generic Clock Channels in a one-to-many relationship. The generators
- * thus allow for several clocks to be generated of different frequencies,
- * power usages, and accuracies, which can be turned on and off individually to
- * disable the clocks to multiple peripherals as a group.
- *
- * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_channels Generic Clock Channels
- * To connect a Generic Clock Generator to a peripheral within the
- * device, a Generic Clock Channel is used. Each peripheral or
- * peripheral group has an associated Generic Clock Channel, which serves as the
- * clock input for the peripheral(s). To supply a clock to the peripheral
- * module(s), the associated channel must be connected to a running Generic
- * Clock Generator and the channel enabled.

- * \section asfdoc_sam0_i2s_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- * \section asfdoc_sam0_i2s_module_overview Module Overview
- *
- * The I2S provides bidirectional, synchronous, digital audio link with external
- * audio devices through these signal pins:
- *  - Serial Data (SDm)
- *  - Frame Sync (FSn)
- *  - Serial Clock (SCKn)
- *  - Master Clock (MCKn)
- *
- * The I2S consists of 2 Clock Units and 2 Serializers, which can be separately
- * configured and enabled, to provide varies functionalities as follow:
- *  - Communicate to Audio CODECs as Master or Slave, or provides clock and
- *    frame sync signals as Controller
- *  - Communicate to DAC or ADC through dedicated I2S serial interface
- *  - Communicate to multi-slot or multiple stereo DACs or ADCs, via
- *    Time Division Multiplexed (TDM) format
- *  - Reading mono or stereo MEMS microphones, using the Pulse Density
- *    Modulation (PDM) interface
- *
- * The I2S supports compact stereo data word, where left channel data bits are
- * in lower half and right channel data bits are in upper half. It reduces the
- * number of data words for stereo audio data and the DMA bandwidth.
- *
- * In master mode, the frame is configured by number of slots and slot size, and
- * allows range covering 16fs to 1024fs MCK, to provide oversampling clock to an
- * external audio CODEC or digital signal processor (DSP).
- *
- * A block diagram of the I2S can be seen in
- * \ref asfdoc_sam0_i2s_module_block_diagram "the figure below".
- *
- * \anchor asfdoc_sam0_i2s_module_block_diagram
- * \image html i2s_blocks.svg "I2S Block Diagram"
- *
- * This driver for I2S module provides an interface to
- *  - initialize and control I2S module
- *  - configure and control the I2S Clock Unit and Serializer
- *  - transmit/receive data through I2S Serializer
- *
- * \subsection asfdoc_sam0_i2s_module_overview_clocks Clocks
- *
- * To use I2S module, the I2S bus interface clock (clk_i2s) must be enabled via
- * Power Manager.
- *
- * For each I2S Clock Unit, a generic clock (gclk_i2s_n) is connnected. When I2S
- * works in master mode the generic clock is used. It should be prepared before
- * clock unit is used. In master mode the input generic clock will be used as
- * MCK for SCKn and FSn generation, in addition, the MCK could be devided and
- * output to I2S MCKn pin, as oversampling clock to external audio device.
- *
- * The I2S Serializer uses clock and control signal from Clock Unit to handle
- * transfer. Select different clock unit with different configurations allows
- * the I2S to work as master or slave, to work on non-related clocks.
- *
- * When using the driver with ASF, enabling the register interface is normally
- * done by the \c init function.
- * The gclk source for the asynchronous domain is normally configured and set
- * through the _configuration struct_ / _init_ function. 
- * If gclk source != 0 is used, this source has to be configured and enabled
- * through invoking the system_gclk driver function when needed, or modifying
- * conf_clock.h to enable it at the beginning.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_frame Audio Frame Generation
- *
- * Audio sample data for all channels are sent in frames, one frame can consist
- * 1 - 8 slots where each slot can be configured to a size 8-bit, 16-bit, 24-bit
- * or 32-bit. The audio frame synch clock is generated by the I2S Clock unit in
- * the master/controller mode. The frame rate (or frame sync frequency) is
- * calculated as follow:
- *
- * FS = SCK / number_of_slots / number_of_bits_in_slot
- *
- * The serial clock (SCK) source is either an external source (slave mode) or
- * generated by the I2S clock unit (controller or master mode) using the MCK as
- * source.
- *
- * SCK = MCK / sck_div
- * \note SCK generation division value is MCKDIV in register.
- *
- * MCK is either an external source or generated using the gclk input from a
- * generic clock generator.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_mode Master, Controller and Slave modes
- *
- * The i2s module has three modes: master, controller and slave.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_mst Master
- * In master mode the module will control the data flow on the i2s bus and can
- * be responsible for clock generation. The Serializers are enabled and will
- * transmit/receive data. On a bus with only master and slave the SCK and FS
- * clock signal will be outputted on the SCK and FS pin on the master module.
- * MCK can optionally be outputted on the MCK pin, if there is a controller
- * module on the bus the SCK, FS and optionally the MCK clock is sourced from
- * the same pins. Serial data will be trancieved on the SD pin in both
- * scenarios.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_ctl Controller
- * In controller mode the module will generate the clock signals, but the
- * Serializers are disabled and no data will be transmitted/received by the
- * module in this mode. The clock signals is outputted on the SCK, FS and
- * optionally the MCK pin.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_slv Slave
- * In slave mode the module will use the SCK and FS clock source from the master
- * or the controller which is received on the SCK and FS pin. The MCK can
- * optionally be sourced externally on the MCK pin. The Serializers are enabled
- * and will tranceive data on the SD pin. All data flow is controlled by the
- * master.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_chg Switch modes
- * The mode switching between master, controller and slave modes are actually
- * done by modifying the source mode of I2S pins.
- * The source mode of I2S pins are selected by writing corresponding bits in
- * CLKCTRLn.
- * Since source mode switching changes the direction of pin, the mode must be
- * changed when the I2S Clock Unit is stopped.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_data Data Stream Reception/Transmission
- *
- * The I2S module support several data stream formats:
- * - I2S format
- * - Time Division Multiplexed (TDM) format
- * - Pulse Density Modulation (PDM) format (reception only)
- *
- * Basically the I2S module can send several words within each frame, it's more
- * like TDM format. With adjust to the number of data words in a frame, the FS
- * width, the FS to data bits delay, etc., the module is able to handle I2S
- * compliant data stream.
- *
- * Also the Serializer can receive PDM format data stream, which allows the I2S
- * module receive 1 PDM data on each SCK edge.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_i2s I2S Stream Reception/Transmission
- *
- * For 2-channel I2S compliant data stream format the i2s module uses the FS
- * line as word select (WS) signal and will send left channel data word on low
- * WS level and right channel data word on high WS level as specified in the I2S
- * standard. The supported word sizes are 8-, 16-, 18-, 20-, 24- and 32- bit.
- *
- * Thus for I2S stream, the following settings should be applied to the module:
- *  - Data starting delay after FS transition : one SCK period
- *  - FS width : half of frame
- *  - Data bits adjust in word : left-adjusted
- *  - Bit transmitting order : MSB first
- *
- * Following is an example for I2S application connections and waveforms. See
- * \ref asfdoc_sam0_i2s_module_i2s_example_diagram "the figure below".
- *
- * \anchor asfdoc_sam0_i2s_module_i2s_example_diagram
- * \image html i2s_example.svg "I2S Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_tdm TDM Stream Reception/Transmission
- * In TDM format, the module sends several data words in each frame. For this
- * data stream format most of the configurations could be adjusted:
- *  - Main Frame related settings are as follow:
- *   - Frame Sync (FS) options:
- *    - the active edge of the FS (or if FS is inverted before use)
- *    - the width of the FS
- *   - the delay between FS to first data bit
- *  - Data alignment in slot
- *  - The number of slots and slot size can be adjusted, it has been mentioned
- *    in \ref asfdoc_sam0_i2s_module_overview_frame
- *  - The data word size is controlled by Serializer, it can be chosen among
- *    8, 16, 18, 20, 24 and 32 bits.
- *
- * The general TDM waveform generation is as follow:
- *
- * \anchor asfdoc_sam0_i2s_module_tdm_wave_diagram
- * \image html tdm_wave.svg "TDM Waveform generation"
- *
- * Some other settings could also be found to set up clock, data formatting and
- * pin mux.
- * refer to \ref i2s_clock_unit_config "Clock Unit Configurations"
- * and \ref i2s_serializer_config "Serializer Configurations" for more
- * details.
- *
- * Following is examples for different application use cases.
- *
- * See \ref asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram "here" for
- * the Time Slot Application connection and waveform example.
- *
- * \anchor asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram
- * \image html tdm_timeslot_example.svg "Codec Example Diagram"
- *
- * See \ref asfdoc_sam0_i2s_module_tdm_codec_example_diagram "here" for the
- * Codec Application connection and waveform example.
- *
- * \anchor asfdoc_sam0_i2s_module_tdm_codec_example_diagram
- * \image html tdm_codec_example.svg "Time Slot Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_pdm PDM Reception
- * The I2S Serializer integrates PDM reception feature, to use this feature,
- * simply select PDM2 mode in Serializer configuration. In PDM2 mode, it assumes
- * two microphones are input for stereo stream. The left microphone bits will
- * be stored in lower half and right microphone bits in upper half of the data
- * word, like in compact stereo format.
- *
- * See \ref asfdoc_sam0_i2s_module_pdm_example_diagram "following figure" for an
- * example of PDM Microphones Application with both left and right channel
- * microphone connected.
- *
- * \anchor asfdoc_sam0_i2s_module_pdm_example_diagram
- * \image html pdm_example.svg "Time PDM2 Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_fmt MONO and Compact Data
- * The I2S Serializer can accept some pre-defined data format and generates
- * the data stream in specified way.
- *
- * When transmitting data, the Serializer can work in MONO mode: assum input
- * is single channel mono data on left channel and copy it to right channel
- * automatically.
- *
- * Also the I2S Serializer can support compact stereo data word. The data word
- * size of the Serializer can be set to \ref I2S_DATA_SIZE_16BIT_COMPACT
- * "16-bit compact" or \ref I2S_DATA_SIZE_8BIT_COMPACT "8-bit compact", with
- * these option I2S Serializer will compact left channel data and right channel
- * data together, the left channel data will take lower bytes and right channel
- * data take higher bytes.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_loop Loop-back Mode
- * The I2S can be configured to loop back the Transmitter to Receiver. In this
- * mode Serializer's input will be connected to another Serializer's output
- * internally.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_sleep Sleep Modes
- * The I2S will continue to operate in any sleep mode, where the selected source
- * clocks are running.
- *
- * \section asfdoc_sam0_i2s_special_considerations Special Considerations
- *
- * There is no special considerations for I2S module.
- *
- * \section asfdoc_sam0_i2s_extra_info Extra Information

-/**
- * \defgroup asfdoc_sam0_system_pinmux_group SAM System Pin Multiplexer (SYSTEM PINMUX) Driver
- *
- * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides
- * an interface for the configuration and management of the device's physical
- * I/O Pins, to alter the direction and input/drive characteristics as well as
- * to configure the pin peripheral multiplexer selection.
- *
- * The following peripheral is used by this module:
- *  - PORT (Port I/O Management)
- *
- * The following devices can use this module:
- *  - Atmel | SMART SAM D20/D21
- *  - Atmel | SMART SAM R21
- *  - Atmel | SMART SAM D09/D10/D11
- *  - Atmel | SMART SAM L21/L22
- *  - Atmel | SMART SAM DA1
- *  - Atmel | SMART SAM C20/C21
- *
- * Physically, the modules are interconnected within the device as shown in the
- * following diagram:
- *
- * The outline of this documentation is as follows:
- *  - \ref asfdoc_sam0_system_pinmux_prerequisites
- *  - \ref asfdoc_sam0_system_pinmux_module_overview
- *  - \ref asfdoc_sam0_system_pinmux_special_considerations
- *  - \ref asfdoc_sam0_system_pinmux_extra_info
- *  - \ref asfdoc_sam0_system_pinmux_examples
- *  - \ref asfdoc_sam0_system_pinmux_api_overview
- *
- *
- * \section asfdoc_sam0_system_pinmux_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_pinmux_module_overview Module Overview
- *
- * The SAM devices contain a number of General Purpose I/O pins, used to
- * interface the user application logic and internal hardware peripherals to
- * an external system. The Pin Multiplexer (PINMUX) driver provides a method
- * of configuring the individual pin peripheral multiplexers to select
- * alternate pin functions.
- *
- * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition
- * <table>
- *  <tr>
- *    <th>Driver Feature Macro</th>
- *    <th>Supported devices</th>
- *  </tr>
- *  <tr>
- *    <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td>
- *    <td>SAM L21, SAM C20/C21</td>
- *  </tr>
- * </table>
- * \note The specific features are only available in the driver when the
- * selected device supports those features.
- *
- * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
- * SAM devices use two naming conventions for the I/O pins in the device; one
- * physical and one logical. Each physical pin on a device package is assigned
- * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
- * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
- * former is used to map physical pins to their physical internal device module
- * counterparts, for simplicity the design of this driver uses the logical GPIO
- * numbers instead.
- *
- * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
- * SAM devices contain a peripheral MUX, which is individually controllable
- * for each I/O pin of the device. The peripheral MUX allows you to select the
- * function of a physical package pin - whether it will be controlled as a user
- * controllable GPIO pin, or whether it will be connected internally to one of
- * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
- * configured in GPIO mode, other peripherals connected to the same pin will be
- * disabled.
- *
- * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
- * There are several special modes that can be selected on one or more I/O pins
- * of the device, which alter the input and output characteristics of the pad.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
- * The Drive Strength configures the strength of the output driver on the
- * pad. Normally, there is a fixed current limit that each I/O pin can safely
- * drive, however some I/O pads offer a higher drive mode which increases this
- * limit for that I/O pin at the expense of an increased power consumption.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
- * The Slew Rate configures the slew rate of the output driver, limiting the
- * rate at which the pad output voltage can change with time.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
- * The Input Sample Mode configures the input sampler buffer of the pad. By
- * default, the input buffer is only sampled "on-demand", i.e. when the user
- * application attempts to read from the input buffer. This mode is the most
- * power efficient, but increases the latency of the input sample by two clock
- * cycles of the port clock. To reduce latency, the input sampler can instead
- * be configured to always sample the input buffer on each port clock cycle, at
- * the expense of an increased power consumption.
- *
- * \subsection asfdoc_sam0_system_pinmux_module_overview_physical Physical Connection
- *
- * \ref asfdoc_sam0_system_pinmux_intconnections "The diagram below" shows
- * how this module is interconnected within the device:
- *
- * \anchor asfdoc_sam0_system_pinmux_intconnections

- *   node [label="Port Pad" shape=square] pad;

- *     node [label="GPIO Module" shape=ellipse shape=ellipse style=filled fillcolor=lightgray] gpio;
- *     node [label="Other Peripheral Modules" shape=ellipse style=filled fillcolor=lightgray] peripherals;
- *   }
- *
- *   pinmux -> gpio;
- *   pad    -> pinmux;
- *   pinmux -> peripherals;
- * }
- * \enddot
- *
- * \section asfdoc_sam0_system_pinmux_special_considerations Special Considerations
- *
- * The SAM port pin input sampling mode is set in groups of four physical
- * pins; setting the sampling mode of any pin in a sub-group of eight I/O pins
- * will configure the sampling mode of the entire sub-group.
- *
- * High Drive Strength output driver mode is not available on all device pins -
- * refer to your device specific datasheet.

- * \section asfdoc_sam0_system_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_module_overview Module Overview
- *
- * The System driver provides a collection of interfaces between the user
- * application logic, and the core device functionality (such as clocks, reset
- * cause determination, etc.) that is required for all applications. It contains
- * a number of sub-modules that control one specific aspect of the device:
- *
- * - System Core (this module)
- * - \ref asfdoc_sam0_system_clock_group "System Clock Control" (sub-module)
- * - \ref asfdoc_sam0_system_interrupt_group "System Interrupt Control" (sub-module)
- * - \ref asfdoc_sam0_system_pinmux_group "System Pin Multiplexer Control" (sub-module)
- *
- *
- * \if DEVICE_SAML21_SYSTEM_SUPPORT
- * \subsection asfdoc_sam0_system_module_overview_vreg_l21 Voltage Regulator
- * The SAM device controls the voltage regulators for the core (VDDCORE) and
- * backup (VDDBU) domains. It sets the voltage regulators according to the sleep
- * modes, the performance level, or the user configuration.
- *
- * In active mode, the voltage regulator can be chosen on the fly between a LDO
- * or a Buck converter. In standby mode, the low power voltage regulator is used
- * to supply VDDCORE.
- *
- * \subsection asfdoc_sam0_system_module_overview_bbps Battery Backup Power Switch
- * The SAM device supports connection of a battery backup to the VBAT power pin.
- * It includes functionality that enables automatic power switching between main
- * power and battery backup power. This will ensure power to the backup domain,
- * when the main battery or power source is unavailable.
- * \endif
- *
- * \if DEVICE_SAMC21_SYSTEM_SUPPORT
- * \subsection asfdoc_sam0_system_module_overview_vreg_c21 Voltage Regulator
- * The SAM device controls the voltage regulators for the core (VDDCORE). It sets
- * the voltage regulators according to the sleep modes.
- *
- * There are a selectable reference voltage and voltage dependent on the temperature
- * which can be used by analog modules like the ADC.
- * \endif
- *
- * \subsection asfdoc_sam0_system_module_overview_vref Voltage References
- * The various analog modules within the SAM devices (such as AC, ADC, and
- * DAC) require a voltage reference to be configured to act as a reference point
- * for comparisons and conversions.
- *
- * The SAM devices contain multiple references, including an internal
- * temperature sensor and a fixed band-gap voltage source. When enabled, the
- * associated voltage reference can be selected within the desired peripheral
- * where applicable.
- *
- * \subsection asfdoc_sam0_system_module_overview_reset_cause System Reset Cause
- * In some applications there may be a need to execute a different program
- * flow based on how the device was reset. For example, if the cause of reset
- * was the Watchdog timer (WDT), this might indicate an error in the application,
- * and a form of error handling or error logging might be needed.
- *
- * For this reason, an API is provided to retrieve the cause of the last system
- * reset, so that appropriate action can be taken.
- *
- * \if DEVICE_SAML21_SYSTEM_SUPPORT
- * There are three groups of reset sources:
- *   - Power supply reset: Resets caused by an electrical issue. It covers POR and BOD reset.
- *   - User reset: Resets caused by the application. It covers external reset,
- *             system reset, and watchdog reset.
- *   - Backup reset: Resets caused by a backup mode exit condition.
- *
- * \subsection asfdoc_sam0_system_module_overview_performance_level Performance Level
- * Performance level allows the user to adjust the regulator output voltage to reduce
- * power consumption. The user can on the fly select the most suitable performance
- * level, depending on the application demands.
- *
- * The SAM device can operate at two different performance levels (PL0 and PL2).
- * When operating at PL0, the voltage applied on the full logic area is reduced
- * by voltage scaling. This voltage scaling technique allows to reduce the active
- * power consumption while decreasing the maximum frequency of the device. When
- * operating at PL2, the voltage regulator supplies the highest voltage, allowing
- * the device to run at higher clock speeds.
- *
- * Performance level transition is possible only when the device is in active
- * mode. After a reset, the device starts at the lowest performance level
- * (lowest power consumption and lowest max. frequency). The application can then
- * switch to another performance level at any time without any stop in the code
- * execution. As shown in \ref asfdoc_sam0_system_performance_level_transition_figure.
- *
- * \note When scaling down the performance level, the bus frequency should first be
- *  scaled down in order to not exceed the maximum frequency allowed for the
- *  low performance level.
- *  When scaling up the performance level (e.g. from PL0 to PL2), check the performance
- *  level status before increasing the bus frequency. It can be increased only
- *  when the performance level transition is completed.
- *
- * \anchor asfdoc_sam0_system_performance_level_transition_figure
- * \image html performance_level_transition.svg "Performance Level Transition"
- *
- * \subsection asfdoc_sam0_system_module_overview_power_domain Power Domain Gating
- * Power domain gating allows power saving by reducing the voltage in logic
- * areas in the device to a low-power supply. The feature is available in
- * Standby sleep mode and will reduce the voltage in domains where all peripherals
- * are idle. Internal logic will maintain its content, meaning the corresponding
- * peripherals will not need to be reconfigured when normal operating voltage
- * is returned. Most power domains can be in the following three states:
- *
- * - Active state: The power domain is powered on.
- * - Retention state: The main voltage supply for the power domain is switched off,
- * while maintaining a secondary low-power supply for the sequential cells. The
- * logic context is restored when waking up.
- * - Off state: The power domain is entirely powered off. The logic context is lost.
- *
- * The SAM L21 device  contains three power domains which can be controlled using
- * power domain gating, namely PD0, PD1, and PD2. These power domains can be
- * configured to the following cases:
- * - Default with no sleepwalking peripherals: A power domain is automatically set
- * to retention state in standby sleep mode if no activity require it. The application
- * can force all power domains to remain in active state during standby sleep mode
- * in order to accelerate wakeup time.
- * - Default with sleepwalking peripherals: If one or more peripherals are enabled
- * to perform sleepwalking tasks in standby sleep mode, the corresponding power
- * domain (PDn) remains in active state as well as all inferior power domains (<PDn).
- * - Sleepwalking with dynamic power domain gating: During standby sleep mode, a
- * power domain (PDn) in active can wake up a superior power domain (>PDn) in order
- * to perform a sleepwalking task. The superior power domain is then automatically
- * set to active state. At the end of the sleepwalking task, the device can either
- * be woken up or the superior power domain can return to retention state.
- *
- * Power domains can be linked to each other, it allows a power domain (PDn) to be kept
- * in active state if the inferior power domain (PDn-1) is in active state too.
- *
- * \ref asfdoc_sam0_system_power_domain_overview_table illustrates the
- * four cases to consider in standby mode.

- *  - \ref asfdoc_sam0_system_interrupt_special_considerations

- *
- *
- * \section asfdoc_sam0_system_interrupt_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_interrupt_module_overview Module Overview
- *
- * The ARM&reg; Cortex&reg; M0+ core contains an interrupt and exception vector table, which
- * can be used to configure the device's interrupt handlers; individual
- * interrupts and exceptions can be enabled and disabled, as well as configured
- * with a variable priority.
- *
- * This driver provides a set of wrappers around the core interrupt functions,
- * to expose a simple API for the management of global and individual interrupts
- * within the device.
- *
- * \subsection asfdoc_sam0_system_interrupt_module_overview_criticalsec Critical Sections
- * In some applications it is important to ensure that no interrupts may be
- * executed by the system whilst a critical portion of code is being run; for
- * example, a buffer may be copied from one context to another - during which
- * interrupts must be disabled to avoid corruption of the source buffer contents
- * until the copy has completed. This driver provides a basic API to enter and
- * exit nested critical sections, so that global interrupts can be kept disabled
- * for as long as necessary to complete a critical application code section.
- *
- * \subsection asfdoc_sam0_system_interrupt_module_overview_softints Software Interrupts
- * For some applications, it may be desirable to raise a module or core
- * interrupt via software. For this reason, a set of APIs to set an interrupt or
- * exception as pending are provided to the user application.
- *
- * \section asfdoc_sam0_system_interrupt_special_considerations Special Considerations
- *
- * Interrupts from peripherals in the SAM devices are on a per-module basis;
- * an interrupt raised from any source within a module will cause a single,
- * module-common handler to execute. It is the user application or driver's
- * responsibility to de-multiplex the module-common interrupt to determine the
- * exact interrupt cause.
- *
- * \section asfdoc_sam0_system_interrupt_extra_info Extra Information

- *
- * \section asfdoc_sam0_tc_module_overview Module Overview
- *
- * The Timer/Counter (TC) module provides a set of timing and counting related
- * functionality, such as the generation of periodic waveforms, the capturing
- * of a periodic waveform's frequency/duty cycle, and software timekeeping for
- * periodic operations. TC modules can be configured to use an 8-, 16-, or
- * 32-bit counter size.
- *
- * This TC module for the SAM is capable of the following functions:
- *
- * - Generation of PWM signals
- * - Generation of timestamps for events
- * - General time counting
- * - Waveform period capture
- * - Waveform frequency capture

- *
- * \subsection asfdoc_sam0_tc_module_overview_func_desc Functional Description
- * Independent of the configured counter size, each TC module can be set up
- * in one of two different modes; capture and compare.
- *
- * In capture mode, the counter value is stored when a configurable event
- * occurs. This mode can be used to generate timestamps used in event capture,
- * or it can be used for the measurement of a periodic input signal's
- * frequency/duty cycle.
- *
- * In compare mode, the counter value is compared against one or more of the
- * configured channel compare values. When the counter value coincides with a
- * compare value an action can be taken automatically by the module, such as
- * generating an output event or toggling a pin when used for frequency or PWM
- * signal generation.
- *
- * \note The connection of events between modules requires the use of the
- *       \ref asfdoc_sam0_events_group "SAM Event System Driver (EVENTS)"
- *       to route output event of one module to the input event of another.
- *       For more information on event routing, refer to the event driver
- *       documentation.
- *
- * \subsection asfdoc_sam0_tc_module_overview_tc_size Timer/Counter Size
- * Each timer module can be configured in one of three different counter
- * sizes; 8-, 16-, and 32-bit. The size of the counter determines the maximum
- * value it can count to before an overflow occurs and the count is reset back
- * to zero. \ref asfdoc_sam0_tc_count_size_vs_top "The table below" shows the
- * maximum values for each of the possible counter sizes.
- *
- * \anchor asfdoc_sam0_tc_count_size_vs_top
- * <table>
- *  <caption>Timer Counter Sizes and Their Maximum Count Values</caption>
- *  <tr>
- *    <th>Counter size</th>
- *    <th>Max. (hexadecimal)</th>
- *    <th>Max. (decimal)</th>
- *  </tr>
- *  <tr>
- *    <td>8-bit</td>
- *    <td>0xFF</td>
- *    <td>255</td>
- *  </tr>
- *  <tr>
- *    <td>16-bit</td>
- *    <td>0xFFFF</td>
- *    <td>65,535</td>
- *  </tr>
- *  <tr>
- *    <td>32-bit</td>
- *    <td>0xFFFFFFFF</td>
- *    <td>4,294,967,295</td>
- *  </tr>
- * </table>
- *
- * When using the counter in 16- or 32-bit count mode, Compare Capture
- * register 0 (CC0) is used to store the period value when running in PWM
- * generation match mode.
- *
- * When using 32-bit counter size, two 16-bit counters are chained together
- * in a cascade formation. Except in SAM D09/D10/D11, Even numbered TC modules
- * (e.g. TC0, TC2) can be configured as 32-bit counters. The odd numbered
- * counters will act as slaves to the even numbered masters, and will not
- * be reconfigurable until the master timer is disabled. The pairing of timer
- * modules for 32-bit mode is shown in \ref asfdoc_sam0_tc_module_ms_pairs
- * "the table below".
- *
- * \anchor asfdoc_sam0_tc_module_ms_pairs
- * <table>
- *   <caption>TC Master and Slave Module Pairings</caption>
- *   <tr>
- *     <th>Master TC Module</th>
- *     <th>Slave TC Module</th>
- *   </tr>
- *   <tr>
- *     <td>TC0</td>
- *     <td>TC1</td>
- *   </tr>
- *   <tr>
- *     <td>TC2</td>
- *     <td>TC3</td>
- *   </tr>
- *   <tr>
- *     <td>...</td>
- *     <td>...</td>
- *   </tr>
- *   <tr>
- *     <td>TCn-1</td>
- *     <td>TCn</td>
- *   </tr>
- * </table>
- *
- * In SAM D09/D10/D11, odd numbered TC modules (e.g. TC1) can be configured as 32-bit
- * counters. The even numbered(e.g. TC2) counters will act as slaves to the odd
- * numbered masters.
- *
- * \subsection asfdoc_sam0_tc_module_overview_clock Clock Settings
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_selection Clock Selection
- * Each TC peripheral is clocked asynchronously to the system clock by a GCLK
- * (Generic Clock) channel. The GCLK channel connects to any of the GCLK
- * generators. The GCLK generators are configured to use one of the available
- * clock sources on the system such as internal oscillator, external crystals,
- * etc. see the \ref asfdoc_sam0_system_clock_group "Generic Clock driver"
- *for
- * more information.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_prescaler Prescaler
- * Each TC module in the SAM has its own individual clock prescaler, which
- * can be used to divide the input clock frequency used in the counter. This
- * prescaler only scales the clock used to provide clock pulses for the counter
- * to count, and does not affect the digital register interface portion of
- * the module, thus the timer registers will synchronize to the raw GCLK
- * frequency input to the module.
- *
- * As a result of this, when selecting a GCLK frequency and timer prescaler
- * value the user application should consider both the timer resolution
- * required and the synchronization frequency, to avoid lengthy
- * synchronization times of the module if a very slow GCLK frequency is fed
- * into the TC module. It is preferable to use a higher module GCLK frequency
- * as the input to the timer, and prescale this down as much as possible to
- * obtain a suitable counter frequency in latency-sensitive applications.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_reloading Reloading
- * Timer modules also contain a configurable reload action, used when a
- * re-trigger event occurs. Examples of a re-trigger event are the counter
- * reaching the maximum value when counting up, or when an event from the event
- * system tells the counter to re-trigger. The reload action determines if the
- * prescaler should be reset, and when this should happen. The counter will
- * always be reloaded with the value it is set to start counting from. The user
- * can choose between three different reload actions, described in
- * \ref asfdoc_sam0_tc_module_reload_act "the table below".
- *
- * \anchor asfdoc_sam0_tc_module_reload_act
- * <table>
- *   <caption>TC Module Reload Actions</caption>
- *   <tr>
- *     <th>Reload action</th>
- *     <th>Description</th>
- *   </tr>
- *   <tr>
- *     <td>\ref TC_RELOAD_ACTION_GCLK </td>
- *     <td>Reload TC counter value on next GCLK cycle. Leave prescaler
- *         as-is.</td>
- *   </tr>
- *   <tr>
- *     <td>\ref TC_RELOAD_ACTION_PRESC </td>
- *     <td>Reloads TC counter value on next prescaler clock. Leave prescaler
- *         as-is.</td>
- *   </tr>
- *  <tr>
- *    <td> \ref TC_RELOAD_ACTION_RESYNC </td>
- *    <td>Reload TC counter value on next GCLK cycle. Clear prescaler to
- *        zero.</td>
- *  </tr>
- * </table>
- *
- * The reload action to use will depend on the specific application being
- * implemented. One example is when an external trigger for a reload occurs; if
- * the TC uses the prescaler, the counter in the prescaler should not have a
- * value between zero and the division factor. The TC counter and the counter
- * in the prescaler should both start at zero. When the counter is set to
- * re-trigger when it reaches the maximum value on the other hand, this is not the
- * right option to use. In such a case it would be better if the prescaler is
- * left unaltered when the re-trigger happens, letting the counter reset on the
- * next GCLK cycle.
- *
- * \subsection asfdoc_sam0_tc_module_overview_compare_match Compare Match Operations
- * In compare match operation, Compare/Capture registers are used in comparison
- * with the counter value. When the timer's count value matches the value of a
- * compare channel, a user defined action can be taken.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_timer Basic Timer
- *
- * A Basic Timer is a simple application where compare match operations is used
- * to determine when a specific period has elapsed. In Basic Timer operations,
- * one or more values in the module's Compare/Capture registers are used to
- * specify the time (as a number of prescaled GCLK cycles) when an action should
- * be taken by the microcontroller. This can be an Interrupt Service Routine
- * (ISR), event generator via the event system, or a software flag that is
- * polled via the user application.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg Waveform Generation
- *
- * Waveform generation enables the TC module to generate square waves, or if
- * combined with an external passive low-pass filter; analog waveforms.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_pwm Waveform Generation - PWM
- *
- * Pulse width modulation is a form of waveform generation and a signalling
- * technique that can be useful in many situations. When PWM mode is used,
- * a digital pulse train with a configurable frequency and duty cycle can be
- * generated by the TC module and output to a GPIO pin of the device.
- *
- * Often PWM is used to communicate a control or information parameter to an
- * external circuit or component. Differing impedances of the source generator
- * and sink receiver circuits is less of an issue when using PWM compared to
- * using an analog voltage value, as noise will not generally affect the
- * signal's integrity to a meaningful extent.
- *
- * \ref asfdoc_sam0_tc_module_pwm_normal_diag "The figure below" illustrates
- * operations and different states of the counter and its output when running
- * the counter in PWM normal mode. As can be seen, the TOP value is unchanged
- * and is set to MAX. The compare match value is changed at several points to
- * illustrate the resulting waveform output changes. The PWM output is set to
- * normal (i.e. non-inverted) output mode.
- *
- * \anchor asfdoc_sam0_tc_module_pwm_normal_diag
- * \image html pwm_normal_ex.svg "Example of PWM in Normal Mode, and Different Counter Operations"
- *
- *
- * In \ref asfdoc_sam0_tc_module_pwm_match_diag "the figure below", the
- * counter is set to generate PWM in Match mode. The PWM output is inverted via
- * the appropriate configuration option in the TC driver configuration
- * structure. In this example, the counter value is changed once, but the
- * compare match value is kept unchanged. As can be seen, it is possible to
- * change the TOP value when running in PWM match mode.
- *
- * \anchor asfdoc_sam0_tc_module_pwm_match_diag
- * \image html pwm_match_ex.svg "Example of PWM in Match Mode, and Different Counter Operations"
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_freq Waveform Generation - Frequency
- *
- * Frequency Generation mode is in many ways identical to PWM
- * generation. However, in Frequency Generation a toggle only occurs
- * on the output when a match on a capture channels occurs. When the
- * match is made, the timer value is reset, resulting in a variable
- * frequency square wave with a fixed 50% duty cycle.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt Capture Operations
- *
- * In capture operations, any event from the event system or a pin change can
- * trigger a capture of the counter value. This captured counter value can be
- * used as a timestamp for the event, or it can be used in frequency and pulse
- * width capture.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_event_capture Capture Operations - Event
- *
- * Event capture is a simple use of the capture functionality,
- * designed to create timestamps for specific events. When the TC
- * module's input capture pin is externally toggled, the current timer
- * count value is copied into a buffered register which can then be
- * read out by the user application.
- *
- * Note that when performing any capture operation, there is a risk that the
- * counter reaches its top value (MAX) when counting up, or the bottom value
- * (zero) when counting down, before the capture event occurs. This can distort
- * the result, making event timestamps to appear shorter than reality; the
- * user application should check for timer overflow when reading a capture
- * result in order to detect this situation and perform an appropriate
- * adjustment.
- *
- * Before checking for a new capture, \ref TC_STATUS_COUNT_OVERFLOW
- * should be checked. The response to an overflow error is left to the user
- * application, however it may be necessary to clear both the capture overflow
- * flag and the capture flag upon each capture reading.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_pwc Capture Operations - Pulse Width
- *
- * Pulse Width Capture mode makes it possible to measure the pulse width and
- * period of PWM signals. This mode uses two capture channels of the counter.
- * This means that the counter module used for Pulse Width Capture can not be
- * used for any other purpose. There are two modes for pulse width capture;
- * Pulse Width Period (PWP) and Period Pulse Width (PPW). In PWP mode, capture
- * channel 0 is used for storing the pulse width and capture channel 1 stores
- * the observed period. While in PPW mode, the roles of the two capture channels
- * is reversed.
- *
- * As in the above example it is necessary to poll on interrupt flags to see
- * if a new capture has happened and check that a capture overflow error has
- * not occurred.
- *
- * \subsection asfdoc_sam0_tc_module_overview_oneshot One-shot Mode
- *
- * TC modules can be configured into a one-shot mode. When configured in this
- * manner, starting the timer will cause it to count until the next overflow
- * or underflow condition before automatically halting, waiting to be manually
- * triggered by the user application software or an event signal from the event
- * system.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_inversion Wave Generation Output Inversion
- *
- * The output of the wave generation can be inverted by hardware if desired,
- * resulting in the logically inverted value being output to the configured
- * device GPIO pin.
- *
- *
- * \section asfdoc_sam0_tc_special_considerations Special Considerations
- *
- * The number of capture compare registers in each TC module is dependent on
- * the specific SAM device being used, and in some cases the counter size.
- *
- * The maximum amount of capture compare registers available in any SAM
- * device is two when running in 32-bit mode and four in 8- and 16-bit modes.

- * \section asfdoc_sam0_wdt_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_wdt_module_overview Module Overview
- *
- * The Watchdog module (WDT) is designed to give an added level of safety in
- * critical systems, to ensure a system reset is triggered in the case of a
- * deadlock or other software malfunction that prevents normal device operation.
- *
- * At a basic level, the Watchdog is a system timer with a fixed period; once
- * enabled, it will continue to count ticks of its asynchronous clock until
- * it is periodically reset, or the timeout period is reached. In the event of a
- * Watchdog timeout, the module will trigger a system reset identical to a pulse
- * of the device's reset pin, resetting all peripherals to their power-on
- * default states and restarting the application software from the reset vector.
- *
- * In many systems, there is an obvious upper bound to the amount of time each
- * iteration of the main application loop can be expected to run, before a
- * malfunction can be assumed (either due to a deadlock waiting on hardware or
- * software, or due to other means). When the Watchdog is configured with a
- * timeout period equal to this upper bound, a malfunction in the system will
- * force a full system reset to allow for a graceful recovery.
- *
- * \subsection asfdoc_sam0_wdt_module_locked_mode Locked Mode
- * The Watchdog configuration can be set in the device fuses and locked in
- * hardware, so that no software changes can be made to the Watchdog
- * configuration. Additionally, the Watchdog can be locked on in software if it
- * is not already locked, so that the module configuration cannot be modified
- * until a power on reset of the device.
- *
- * The locked configuration can be used to ensure that faulty software does not
- * cause the Watchdog configuration to be changed, preserving the level of
- * safety given by the module.
- *
- * \subsection asfdoc_sam0_wdt_module_window_mode Window Mode
- * Just as there is a reasonable upper bound to the time the main program loop
- * should take for each iteration, there is also in many applications a lower
- * bound, i.e. a \a minimum time for which each loop iteration should run for
- * under normal circumstances. To guard against a system failure resetting the
- * Watchdog in a tight loop (or a failure in the system application causing the
- * main loop to run faster than expected) a "Window" mode can be enabled to
- * disallow resetting of the Watchdog counter before a certain period of time.
- * If the Watchdog is not reset \a after the window opens but not \a before the
- * Watchdog expires, the system will reset.
- *
- * \subsection asfdoc_sam0_wdt_module_early_warning Early Warning
- * In some cases it is desirable to receive an early warning that the Watchdog is
- * about to expire, so that some system action (such as saving any system
- * configuration data for failure analysis purposes) can be performed before the
- * system reset occurs. The Early Warning feature of the Watchdog module allows
- * such a notification to be requested; after the configured early warning time
- * (but before the expiry of the Watchdog counter) the Early Warning flag will
- * become set, so that the user application can take an appropriate action.
- *
- * \note It is important to note that the purpose of the Early Warning feature
- *       is \a not to allow the user application to reset the Watchdog; doing
- *       so will defeat the safety the module gives to the user application.
- *       Instead, this feature should be used purely to perform any tasks that
- *       need to be undertaken before the system reset occurs.
- *
- * \subsection asfdoc_sam0_wdt_module_overview_physical Physical Connection
- *
- * \ref asfdoc_sam0_wdt_module_int_connections "The figure below" shows how
- * this module is interconnected within the device.
- *

- * }
- * \enddot
- *
- * \note Watchdog Counter of SAM L21/L22 is \a not provided by GCLK, but it uses an
- *       internal 1KHz OSCULP32K output clock.
- *
- * \section asfdoc_sam0_wdt_special_considerations Special Considerations
- *
- * On some devices the Watchdog configuration can be fused to be always on in
- * a particular configuration; if this mode is enabled the Watchdog is not
- * software configurable and can have its count reset and early warning state
- * checked/cleared only.

-    // On SAMD, when the WDT fires, that's it, the chip's getting reset.
-    // Instead, it has an "early warning interrupt" with a different set
-    // interval prior to the reset.  For equivalent behavior to the AVR
-    // library, this requires a slightly different configuration depending
-    // whether we're coming from the sleep() function (which needs the

-    // occurs) follows this and is always just set to the max, since the
-    // interrupt will trigger first.  In the enable case, windowed mode
-    // is not used, the WDT period is set and that's that.

-# ArduinoHttpClient
-
-ArduinoHttpClient is a library to make it easier to interact with web servers from Arduino.
-
-Derived from [Adrian McEwen's HttpClient library](https://github.com/amcewen/HttpClient)
-
-## Dependencies
-
-- Requires a networking hardware and a library that provides transport specific `Client` instance, such as:
-  - [WiFi101](https://github.com/arduino-libraries/WiFi101)
-  - [Ethernet](https://github.com/arduino-libraries/Ethernet)
-  - [WiFi](https://github.com/arduino-libraries/WiFi)
-  - [GSM](https://github.com/arduino-libraries/GSM)
-
-## Usage
-
-In normal usage, handles the outgoing request and Host header.  The returned status code is parsed for you, as is the Content-Length header (if present).
-
-Because it expects an object of type Client, you can use it with any of the networking classes that derive from that.  Which means it will work with WiFiClient, EthernetClient and GSMClient.
-
-See the examples for more detail on how the library is used.

-
-  The body of the PUT request looks like this:

-Thank you for opening an issue on an Adafruit Arduino library repository.  To
-improve the speed of resolution please review the following guidelines and
-common troubleshooting steps below before creating the issue:
-
-- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
-  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
-  something isn't working as expected.  In many cases the problem is a common issue
-  that you will more quickly receive help from the forum community.  GitHub issues
-  are meant for known defects in the code.  If you don't know if there is a defect
-  in the code then start with troubleshooting on the forum first.
-
-- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
-  check all of the steps and commands to run have been followed.  Consult the
-  forum if you're unsure or have questions about steps in a guide/tutorial.
-
-- **For Arduino projects check these very common issues to ensure they don't apply**:
-
-  - For uploading sketches or communicating with the board make sure you're using
-    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
-    very hard to tell the difference between a data and charge cable!  Try using the
-    cable with other devices or swapping to another cable to confirm it is not
-    the problem.
-
-  - **Be sure you are supplying adequate power to the board.**  Check the specs of
-    your board and plug in an external power supply.  In many cases just
-    plugging a board into your computer is not enough to power it and other
-    peripherals.
-
-  - **Double check all soldering joints and connections.**  Flakey connections
-    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
-
-  - **Ensure you are using an official Arduino or Adafruit board.** We can't
-    guarantee a clone board will have the same functionality and work as expected
-    with this code and don't support them.
-
-If you're sure this issue is a defect in the code and checked the steps above
-please fill in the following fields to provide enough troubleshooting information.
-You may delete the guideline and text above to just leave the following details:
-
-- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
-
-- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
-  VERSION HERE**
-
-- List the steps to reproduce the problem below (if possible attach a sketch or
-  copy the sketch code in too): **LIST REPRO STEPS BELOW**

-Thank you for creating a pull request to contribute to Adafruit's GitHub code!
-Before you open the request please review the following guidelines and tips to
-help it be more easily integrated:
-
-- **Describe the scope of your change--i.e. what the change does and what parts
-  of the code were modified.**  This will help us understand any risks of integrating
-  the code.
-
-- **Describe any known limitations with your change.**  For example if the change
-  doesn't apply to a supported platform of the library please mention it.
-
-- **Please run any tests or examples that can exercise your modified code.**  We
-  strive to not break users of the code and running tests/examples helps with this
-  process.
-
-Thank you again for contributing!  We will try to test and integrate the change
-as soon as we can, but be aware we have many GitHub repositories to manage and
-can't immediately respond to every request.  There is no need to bump or check in
-on a pull request (it will clutter the discussion of the request).
-
-Also don't be worried if the request is closed or not integrated--sometimes the
-priorities of Adafruit's GitHub code (education, ease of use) might not match the
-priorities of the pull request.  Don't fret, the open source community thrives on
-forks and GitHub makes it easy to keep your changes in a forked repo.
-
-After reviewing the guidelines above you can delete this text from the pull request.

-Thank you for opening an issue on an Adafruit Arduino library repository.  To
-improve the speed of resolution please review the following guidelines and
-common troubleshooting steps below before creating the issue:
-
-- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
-  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
-  something isn't working as expected.  In many cases the problem is a common issue
-  that you will more quickly receive help from the forum community.  GitHub issues
-  are meant for known defects in the code.  If you don't know if there is a defect
-  in the code then start with troubleshooting on the forum first.
-
-- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
-  check all of the steps and commands to run have been followed.  Consult the
-  forum if you're unsure or have questions about steps in a guide/tutorial.
-
-- **For Arduino projects check these very common issues to ensure they don't apply**:
-
-  - For uploading sketches or communicating with the board make sure you're using
-    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
-    very hard to tell the difference between a data and charge cable!  Try using the
-    cable with other devices or swapping to another cable to confirm it is not
-    the problem.
-
-  - **Be sure you are supplying adequate power to the board.**  Check the specs of
-    your board and plug in an external power supply.  In many cases just
-    plugging a board into your computer is not enough to power it and other
-    peripherals.
-
-  - **Double check all soldering joints and connections.**  Flakey connections
-    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
-
-  - **Ensure you are using an official Arduino or Adafruit board.** We can't
-    guarantee a clone board will have the same functionality and work as expected
-    with this code and don't support them.
-
-If you're sure this issue is a defect in the code and checked the steps above
-please fill in the following fields to provide enough troubleshooting information.
-You may delete the guideline and text above to just leave the following details:
-
-- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
-
-- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
-  VERSION HERE**
-
-- List the steps to reproduce the problem below (if possible attach a sketch or
-  copy the sketch code in too): **LIST REPRO STEPS BELOW**

-Thank you for creating a pull request to contribute to Adafruit's GitHub code!
-Before you open the request please review the following guidelines and tips to
-help it be more easily integrated:
-
-- **Describe the scope of your change--i.e. what the change does and what parts
-  of the code were modified.**  This will help us understand any risks of integrating
-  the code.
-
-- **Describe any known limitations with your change.**  For example if the change
-  doesn't apply to a supported platform of the library please mention it.
-
-- **Please run any tests or examples that can exercise your modified code.**  We
-  strive to not break users of the code and running tests/examples helps with this
-  process.
-
-Thank you again for contributing!  We will try to test and integrate the change
-as soon as we can, but be aware we have many GitHub repositories to manage and
-can't immediately respond to every request.  There is no need to bump or check in
-on a pull request (it will clutter the discussion of the request).
-
-Also don't be worried if the request is closed or not integrated--sometimes the
-priorities of Adafruit's GitHub code (education, ease of use) might not match the
-priorities of the pull request.  Don't fret, the open source community thrives on
-forks and GitHub makes it easy to keep your changes in a forked repo.
-
-After reviewing the guidelines above you can delete this text from the pull request.

-  WiFi Web Server LED Blink
-
-  A simple web server that lets you blink an LED via the web.
-  This sketch will create a new access point (with no password).
-  It will then launch a new server and print out the IP address
-  to the Serial monitor. From there, you can open that address in a web browser
-  to turn on and off the LED on pin 13.
-
-  If the IP address of your shield is yourAddress:
-    http://yourAddress/H turns the LED on
-    http://yourAddress/L turns it off
-
-  created 25 Nov 2012

- This example connects to a WEP-encrypted WiFi network.

-
- If you use 40-bit WEP, you need a key that is 10 characters long,
- and the characters must be hexadecimal (0-9 or A-F).
- e.g.  for 40-bit, ABBADEAF01 will work, but ABBADEAF won't work
- (too short) and ABBAISDEAF won't work (I and S are not
- hexadecimal characters).
-
- For 128-bit, you need a string that is 26 characters long.
- D0D0DEADF00DABBADEAFBEADED will work because it's 26 characters,
- all in the 0-9, A-F range.

- MDNS WiFi Web Server
-
- A simple web server that shows the value of the analog input pins,
- and exposes itself on the MDNS name 'wifi101.local'.
-
- On Linux (like Ubuntu 15.04) or OSX you can access the web page
- on the device in a browser at 'http://wifi101.local/'.
-
- On Windows you'll first need to install the Bonjour Printer Services
- from:
-   https://support.apple.com/kb/dl999?locale=en_US
- Then you can access the device in a browser at 'http://wifi101.local/'.
-
- This example is written for a network using WPA encryption. For
- WEP or WPA, change the WiFi.begin() call accordingly.
-
- Circuit:
- * WiFi shield attached
- * Analog inputs attached to pins A0 through A5 (optional)

-# Heatseek Feather Sensor
-
-## Building Project
-
-1. Ensure you're on (at least) version 1.6.13 of the Arduino IDE
-1. Place the contents of the libraries directory in your Arduino user libraries directory.  (Usually `~/Documents/Arduino/libraries`)
-1. Set up WICED Feather using [steps here](https://learn.adafruit.com/introducing-the-adafruit-wiced-feather-wifi/).
-1. Set up M0 Feather using [steps here](https://learn.adafruit.com/adafruit-feather-m0-basic-proto/setup).
-1. Set up M0 WiFi Feather using [steps here](https://learn.adafruit.com/adafruit-feather-m0-wifi-atwinc1500/using-the-wifi-module). Be sure to do the version check as described.
-1. In `user_config.h`, uncomment the appropriate line depending on which microprocessor board you are using.  Only one board type line in this file should be uncommented.
-
-## Software
-
-### Outline
-
-1. Prompt user to set RTC clock time if necessary.  (TODO: set this by web request).
-1. If last reading time exceeds reading interval, take a new reading.
-1. Store the reading on the SD card.
-1. Store the reading time on SD card for comparison against reading interval.
-
-### Notes
-
-- Always prioritize logging data to SD card.  The microprocessor should always reboot and continue taking readings if there is a problem transmitting the data.
-- TODO: Ensure device is not on battery power prior to writing to SD card.

-# feather_sensor_transmit_lte
-
-A Particle project named feather_sensor_transmit_lte
-
-## Welcome to your project!
-
-Every new Particle project is composed of 3 important elements that you'll see have been created in your project directory for feather_sensor_transmit_lte.
-
-#### ```/src``` folder:  
-This is the source folder that contains the firmware files for your project. It should *not* be renamed. 
-Anything that is in this folder when you compile your project will be sent to our compile service and compiled into a firmware binary for the Particle device that you have targeted.
-
-If your application contains multiple files, they should all be included in the `src` folder. If your firmware depends on Particle libraries, those dependencies are specified in the `project.properties` file referenced below.
-
-#### ```.ino``` file:
-This file is the firmware that will run as the primary application on your Particle device. It contains a `setup()` and `loop()` function, and can be written in Wiring or C/C++. For more information about using the Particle firmware API to create firmware for your Particle device, refer to the [Firmware Reference](https://docs.particle.io/reference/firmware/) section of the Particle documentation.
-
-#### ```project.properties``` file:  
-This is the file that specifies the name and version number of the libraries that your project depends on. Dependencies are added automatically to your `project.properties` file when you add a library to a project using the `particle library add` command in the CLI or add a library in the Desktop IDE.
-
-## Adding additional files to your project
-
-#### Projects with multiple sources
-If you would like add additional files to your application, they should be added to the `/src` folder. All files in the `/src` folder will be sent to the Particle Cloud to produce a compiled binary.
-
-#### Projects with external libraries
-If your project includes a library that has not been registered in the Particle libraries system, you should create a new folder named `/lib/<libraryname>/src` under `/<project dir>` and add the `.h`, `.cpp` & `library.properties` files for your library there. Read the [Firmware Libraries guide](https://docs.particle.io/guide/tools-and-features/libraries/) for more details on how to develop libraries. Note that all contents of the `/lib` folder and subfolders will also be sent to the Cloud for compilation.
-
-## Compiling your project
-
-When you're ready to compile your project, make sure you have the correct Particle device target selected and run `particle compile <platform>` in the CLI or click the Compile button in the Desktop IDE. The following files in your project folder will be sent to the compile service:
-
-- Everything in the `/src` folder, including your `.ino` application file
-- The `project.properties` file for your project
-- Any libraries stored under `lib/<libraryname>/src`

-The Arduino SdFat library provides read/write access to FAT16/FAT32
-file systems on SD/SDHC flash cards.
-
-SdFat requires Arduino 1.6x or greater.
-
-Key changes:
-
-Support for multiple SPI ports now uses a pointer to a SPIClass object.
-
-See the STM32Test example.
-```
-explicit SdFat(SPIClass* spiPort);
-\\ or
-explicit SdFatEX(SPIClass* spiPort);
-```
-
-Open flags now follow POSIX conventions.  O_RDONLY is the same as O_READ and O_WRONLY is the
-same as O_WRITE. One and only one of of the mode flags, O_RDONLY, O_RDWR, or
-O_WRONLY is required.
- 
-Open flags for Particle Gen3 and ARM boards are now defined by fcntl.h.
-See SdFatConfig.h for options.
-
-Support for particle Gen3 devices.
-
-New cluster allocation algorithm.
-
-Please read changes.txt and the html documentation in the extras folder for more information.
-
-Please report problems as issues.
-
-A number of configuration options can be set by editing SdFatConfig.h
-define macros.  See the html documentation for details
-
-Please read the html documentation for this library.  Start with
-html/index.html and read the Main Page.  Next go to the Classes tab and
-read the documentation for the classes SdFat, SdFatEX, SdBaseFile,
-SdFile, File, StdioStream, ifstream, ofstream, and others.
- 
-Please continue by reading the html documentation in SdFat/extras/html

-/**
- * This program logs data from the Arduino ADC to a binary file.
- *
- * Samples are logged at regular intervals. Each Sample consists of the ADC
- * values for the analog pins defined in the PIN_LIST array.  The pins numbers
- * may be in any order.
- *
- * Edit the configuration constants below to set the sample pins, sample rate,
- * and other configuration values.
- *
- * If your SD card has a long write latency, it may be necessary to use
- * slower sample rates.  Using a Mega Arduino helps overcome latency
- * problems since 13 512 byte buffers will be used.
- *
- * Each 512 byte data block in the file has a four byte header followed by up
- * to 508 bytes of data. (508 values in 8-bit mode or 254 values in 10-bit mode)
- * Each block contains an integral number of samples with unused space at the
- * end of the block.
- *
- * Data is written to the file using a SD multiple block write command.

-/**
- * This program logs data to a binary file.  Functions are included
- * to convert the binary file to a csv text file.
- *
- * Samples are logged at regular intervals.  The maximum logging rate
- * depends on the quality of your SD card and the time required to
- * read sensor data.  This example has been tested at 500 Hz with
- * good SD card on an Uno.  4000 HZ is possible on a Due.
- *
- * If your SD card has a long write latency, it may be necessary to use
- * slower sample rates.  Using a Mega Arduino helps overcome latency
- * problems since 12 512 byte buffers will be used.
- *
- * Data is written to the file using a SD multiple block write command.

-/**
- * This program logs data to a binary file.  Functions are included
- * to convert the binary file to a csv text file.
- *
- * Samples are logged at regular intervals.  The maximum logging rate
- * depends on the quality of your SD card and the time required to
- * read sensor data.  This example has been tested at 500 Hz with
- * good SD card on an Uno.  4000 HZ is possible on a Due.
- *
- * If your SD card has a long write latency, it may be necessary to use
- * slower sample rates.  Using a Mega Arduino helps overcome latency
- * problems since 12 512 byte buffers will be used.
- *
- * Data is written to the file using a SD multiple block write command.

-/**
- * This program logs data to a binary file.  Functions are included
- * to convert the binary file to a csv text file.
- *
- * Samples are logged at regular intervals.  The maximum logging rate
- * depends on the quality of your SD card and the time required to
- * read sensor data.  This example has been tested at 500 Hz with
- * good SD card on an Uno.  4000 HZ is possible on a Due.
- *
- * If your SD card has a long write latency, it may be necessary to use
- * slower sample rates.  Using a Mega Arduino helps overcome latency
- * problems since 12 512 byte buffers will be used.
- *
- * Data is written to the file using a SD multiple block write command.

-Static Tests of the Arduino Internal ADC.
-
-Several people have asked about the DC accuracy of the Arduino ADC when used in my data logging applications at slow sample rates.
-
-Here are my results of some "hobby level" measurements of the Arduino ADC.
-
-One question is how important is the ADC clock rate.  I did measurents for an ADC clock rate of 125 kHz to 2MHz.
-
-Another question is how much does Noise Reduction Mode help.  I did a series of measurements using this mode.
-
-Noise Reduction Mode only reduced the mean absolute error slightly.
-
-I do calibration to remove Offset Error and Gain Error.  Calibration is very important for good accuracy.
-
-These tests depend on the Arduino voltage regulator providing a stable voltage during the tests.  The Arduino ADC reference voltage is Vcc for these tests.  This may not be realistic for practical applications
-
-Integral Non-linearity (INL) is the main remaining source of error.
-
-Here are my results for static (DC) tests of the internal ADC for three UNOs.
-
-The Arduinos are powered by a high quality nine volt power supply.
-
-These tests measure a DC level so do not include problems due to time jitter, S/H time, and other dynamic errors.
-There are several studies of the dynamic behavior of the Arduino ADC that determine ENOB (Effective Number Of Bits).
-
-I used a shield with a 12-bit MCP4921 DAC to generate voltage levels. This ADC has an output buffer so it provides a very low impedance source.
-
-I measured the voltage of the DAC with a calibrated 18-bit MCP3422 ADC on the shield.
-
-I used DAC levels from 20 to 4075 to avoid zero offset errors at low voltages and DAC buffer problems at high voltages.
-
-Each series of measurements has 4056 data points.
-
-This is a voltage range of about 0.023 to 4.972 volts.
-
-I calibrated the Arduino ADC for each series of measurements with a linear fit of the form.
-
-v = a + b*adcValue
-
-Errors are the difference between the value measured with the 18-bit ADC and the calibrated value measured with the AVR ADC.
-
-I also show the results for no calibration, the NoCal column, using the datasheet formula.
-
-Vin = Vref*adcValue/1024
-
-
-The rows in the tables tables are.
-
-Min - minimum error in millivolts
-
-Max - maximum error in millivolts
-
-MAE - mean absolute error in millivolts
-
-
-The columns in the tables are:
-
-Ideal - results for a perfect 10-bit ADC for comparison.
-
-NoCal - datasheet formula (5/1024)*adcValue with Noise Reduction Mode.
-
-NR128 - Noise Reduction mode with Prescaler of 128 (ADC clock of 125 kHz).
-
-PS128 - analogRead with Prescaler of 128 (ADC clock of 125 kHz).
-
-PS64 - analogRead with Prescaler of 64 (ADC clock of 250 kHz).
-
-PS32 - analogRead with Prescaler of 32 (ADC clock of 500 kHz).
-
-PS16 - analogRead with Prescaler of 16 (ADC clock of 1 MHz).

-AnalogBinLogger.ino logs analog data to a binary SD file at high rates.
-
-Samples are logged at regular intervals by using timer1.  Timer/Counter1
-Compare Match B is used to trigger the ADC for the first pin in a sample.
-The ADC is triggered for remaining sample pins in the ADC conversion complete
-interrupt routine.
-
-Data is captured in the ADC interrupt routine and saved in 512 byte buffers.
-
-Buffered data is written to the SD in a function called from loop().  The
-entire data set is written to a large contiguous file as a single multi-block
-write.  This reduces write latency problems.
-
-Many inexpensive SD cards work well at lower rates.  I used a $6.00

-
-SanDisk class 4 cards work well at fairly high rates.  I used the 4 GB SanDisk
-card to log a single pin at 40,000 samples per second.
-
-You may need to increase the time between samples if your card has higher
-latency.  Using a Mega Arduino can help since it has more buffering.

-
-The accuracy of the ADC samples depends on the ADC clock rate.  See the

-All commands can be terminated by entering a character from the serial monitor.
-
-The c command converts the current binary file to a text file.  Entering a

-The d command converts the binary file to text and displays it on the serial
-monitor.  Entering a character on the serial monitor terminates the command.
-
-The e command displays details about overruns in the current binary file.
-Data overruns happen when data samples are lost due to long write latency
-of the SD.
-
-The r command will record ADC data to a binary file.  It will terminate
-when a character is entered on the serial monitor or the the maximum file

-\mainpage Arduino %SdFat Library
-<CENTER>Copyright &copy 2012-2018 by William Greiman
-</CENTER>
-
-\section Intro Introduction
-The Arduino %SdFat Library is a minimal implementation of FAT16 and FAT32
-file systems on SD flash memory cards. Standard SD and high capacity SDHC
-cards are supported.
-
-Experimental support for FAT12 can be enabled by setting FAT12_SUPPORT
-nonzero in SdFatConfig.h.
-
-The %SdFat library supports Long %File Names or short 8.3 names.
-Edit the SdFatConfig.h file to select short or long file names.
-
-The main classes in %SdFat are SdFat, SdFatEX, SdFatSoftSpi, SdFatSoftSpiEX,
-SdBaseFile, SdFile, File, StdioStream, \ref fstream, \ref ifstream,
-and \ref ofstream.
-
-The SdFat, SdFatEX, SdFatSoftSpi and SdFatSoftSpiEX classes maintain a
-FAT volume, a current working directory, and simplify initialization
-of other classes. The SdFat and SdFatEX classes uses a fast custom hardware SPI
-implementation.  The SdFatSoftSpi and SdFatSoftSpiEX classes uses software SPI.
-
-the SdFatEX and SdFatSoftSpiEX use extended multi-block I/O for enhanced
-performance.  These classes must have exclusive use of the SPI bus.
-
-The SdBaseFile class provides basic file access functions such as open(),
-binary read(), binary write(), close(), remove(), and sync(). SdBaseFile
-is the smallest file class.
-
-The SdFile class has all the SdBaseFile class functions plus the Arduino
-Print class functions.
-
-The File class has all the SdBaseFile functions plus the functions in
-the Arduino SD.h File class. This provides compatibility with the
-Arduino SD.h library.
-
-The StdioStream class implements functions similar to Linux/Unix standard
-buffered input/output.
-
-The \ref fstream class implements C++ iostreams for both reading and writing
-text files.
-
-The \ref ifstream class implements C++ iostreams for reading text files.
-
-The \ref ofstream class implements C++ iostreams for writing text files.
-
-The classes \ref ifstream, \ref ofstream, \ref istream, and \ref ostream
-follow the C++ \ref iostream standard when possible.
-
-There are many tutorials and much documentation about using C++ iostreams
-on the web.
-
-http://www.cplusplus.com/  is a good C++ site for learning iostreams.
-
-The classes \ref ibufstream and \ref obufstream format and parse character
- strings in memory buffers.
-
-the classes ArduinoInStream and ArduinoOutStream provide iostream functions
-for Serial, LiquidCrystal, and other devices.
-
-A number of example are provided in the %SdFat/examples folder.  These were
-developed to test %SdFat and illustrate its use.
-
-\section Install Installation
-
-You must manually install SdFat by copying the SdFat folder from the download
-package to the Arduino libraries folder in your sketch folder.
-
-See the Manual installation section of this guide.
-
-http://arduino.cc/en/Guide/Libraries
-
-\section SDconfig SdFat Configuration
-
-Several configuration options may be changed by editing the SdFatConfig.h
-file in the %SdFat folder.
-
-Set USE_LONG_FILE_NAMES nonzero to enable Long %File Names.  By default,
-Long %File Names are enabled. For the leanest fastest library disable
-Long %File Names.  Long %File names require extra flash but no extra RAM.
-Opening Long %File Names can be slower than opening Short %File Names.
-Data read and write performance is not changed by the type of %File Name.
-
-If the symbol ENABLE_EXTENDED_TRANSFER_CLASS is nonzero, the class SdFatEX
-will be defined. If the symbol ENABLE_SOFTWARE_SPI_CLASS is also nonzero,
-the class SdFatSoftSpiEX will be defined.
-These classes used extended multi-block SD I/O for better performance.
-the SPI bus may not be shared with other devices in this mode.
-
-Set USE_STANDARD_SPI_LIBRARY and  ENABLE_SOFTWARE_SPI_CLASS to
-enable various SPI options. set USE_STANDARD_SPI_LIBRARY to use the standard
-Arduino SPI library. set ENABLE_SOFTWARE_SPI_CLASS to enable the SdFatSoftSpi
-class which uses software SPI.
-
-To enable SD card CRC checking set USE_SD_CRC nonzero.
-
-Set FAT12_SUPPORT nonzero to enable use of FAT12 volumes.
-FAT12 has not been well tested and requires additional flash.
-
-\section SDPath Paths and Working Directories
-
-Relative paths in SdFat are resolved in a manner similar to Windows.
-
-Each instance of SdFat has a current directory.  In SdFat this directory
-is called the volume working directory, vwd.  Initially this directory is
-the root directory for the volume.
-
-The volume working directory is changed by calling SdFat::chdir(path).
-
-The call sd.chdir("/2014") will change the volume working directory
-for sd to "/2014", assuming "/2014" exists.
-
-Relative paths for SdFat member functions are resolved by starting at
-the volume working directory.
-
-For example, the call sd.mkdir("April") will create the directory
-"/2014/April" assuming the volume working directory is "/2014".
-
-SdFat has a current working directory, cwd, that is used to resolve paths
-for file.open() calls.
-
-For a single SD card the current working directory is always the volume
-working directory for that card.
-
-For multiple SD cards the current working directory is set to the volume
-working directory of a card by calling the SdFat::chvol() member function.
-The chvol() call is like the Windows \<drive letter>: command.
-
-The call sd2.chvol() will set the current working directory to the volume
-working directory for sd2.
-
-If the volume working directory for sd2 is "/music" the call
-
-file.open("BigBand.wav", O_READ);
-
-will then open "/music/BigBand.wav" on sd2.
-
-The following functions are used to change or get current directories.
-See the html documentation for more information.
-@code
-bool SdFat::chdir(bool set_cwd = false);
-bool SdFat::chdir(const char* path, bool set_cwd = false);
-void SdFat::chvol();
-SdBaseFile* SdFat::vwd();
-static SdBaseFile* SdBaseFile::cwd();
-@endcode
-
-\section SDcard SD\SDHC Cards
-
-Arduinos access SD cards using the cards SPI protocol.  PCs, Macs, and
-most consumer devices use the 4-bit parallel SD protocol.  A card that
-functions well on A PC or Mac may not work well on the Arduino.
-
-Most cards have good SPI read performance but cards vary widely in SPI
-write performance.  Write performance is limited by how efficiently the
-card manages internal erase/remapping operations.  The Arduino cannot
-optimize writes to reduce erase operations because of its limit RAM.
-
-SanDisk cards generally have good write performance.  They seem to have
-more internal RAM buffering than other cards and therefore can limit
-the number of flash erase operations that the Arduino forces due to its
-limited RAM.
-
-\section Hardware Hardware Configuration
-
-%SdFat was developed using an
-<A HREF = "http://www.adafruit.com/"> Adafruit Industries</A>
-Data Logging Shield.
-
-The hardware interface to the SD card should not use a resistor based level
-shifter.  %SdFat sets the SPI bus frequency to 8 MHz which results in signal
-rise times that are too slow for the edge detectors in many newer SD card
-controllers when resistor voltage dividers are used.
-
-The 5 to 3.3 V level shifter for 5 V Arduinos should be IC based like the
-74HC4050N based circuit shown in the file SdLevel.png.  The Adafruit Wave Shield
-uses a 74AHC125N.  Gravitech sells SD and MicroSD Card Adapters based on the
-74LCX245.
-
-If you are using a resistor based level shifter and are having problems try
-setting the SPI bus frequency to 4 MHz.  This can be done by using
-card.init(SPI_HALF_SPEED) to initialize the SD card.
-
-A feature to use software SPI is available.  Software SPI is slower
-than hardware SPI but allows any digital pins to be used.  See
-SdFatConfig.h for software SPI definitions.
-
-\section comment Bugs and Comments
-
-If you wish to report bugs or have comments, send email to
-fat16lib@sbcglobal.net.  If possible, include a simple program that illustrates
-the bug or problem.
-
-\section Trouble Troubleshooting
-
-The two example programs QuickStart, and SdInfo are useful for troubleshooting.
-
-A message like this from SdInfo with errorCode 0X1 indicates the SD card
-is not seen by SdFat.  This is often caused by a wiring error and reformatting
-the card will not solve the problem.
-<PRE>
-cardBegin failed
-SD errorCode: 0X1
-SD errorData: 0XFF
-</PRE>
-Here is a similar message from QuickStart:
-<PRE>
-SD initialization failed.
-Do not reformat the card!
-Is the card correctly inserted?
-Is chipSelect set to the correct value?
-Does another SPI device need to be disabled?
-Is there a wiring/soldering problem?
-
-errorCode: 0x1, errorData: 0xff
-</PRE>
-Here is a message from QuickStart that indicates a formatting problem:
-<PRE>
-Card successfully initialized.
-Can't find a valid FAT16/FAT32 partition.
-Try reformatting the card.  For best results use
-the SdFormatter program in SdFat/examples or download
-and use SDFormatter from www.sdcard.org/downloads.
-</PRE>

-\section SdFatClass SdFat Usage
-
-SdFat supports Long File Names.  Long names in SdFat are limited to 7-bit
-ASCII characters in the range 0X20 - 0XFE The following are reserved characters:
-    <ul>
-    <li>< (less than)
-    <li>> (greater than)
-    <li>: (colon)
-    <li>" (double quote)
-    <li>/ (forward slash)
-    <li>\ (backslash)
-    <li>| (vertical bar or pipe)
-    <li>? (question mark)
-    <li>* (asterisk)
-    </ul>
-%SdFat uses a slightly restricted form of short names.
-Short names are limited to 8 characters followed by an optional period (.)
-and extension of up to 3 characters.  The characters may be any combination
-of letters and digits.  The following special characters are also allowed:
-
-$ % ' - _ @ ~ ` ! ( ) { } ^ # &
-
-Short names are always converted to upper case and their original case
-value is lost.  Files that have a base-name where all characters have the
-same case and an extension where all characters have the same case will
-display properly.  Examples this type name are UPPER.low, lower.TXT,
-UPPER.TXT, and lower.txt.
-
-An application which writes to a file using print(), println() or
-write() must close the file or call sync() at the appropriate time to
-force data and directory information to be written to the SD Card.
-
-Applications must use care calling sync()
-since 2048 bytes of I/O is required to update file and
-directory information.  This includes writing the current data block, reading
-the block that contains the directory entry for update, writing the directory
-block back and reading back the current data block.
-
-It is possible to open a file with two or more instances of a file object.
-A file may be corrupted if data is written to the file by more than one
-instance of a file object.
-
-\section HowTo How to format SD Cards as FAT Volumes
-
-The best way to restore an SD card's format on a PC or Mac is to use
-SDFormatter which can be downloaded from:
-
-http://www.sdcard.org/downloads
-
-A formatter program, SdFormatter.ino, is included in the
-%SdFat/examples/SdFormatter directory.  This program attempts to
-emulate SD Association's SDFormatter.
-
-SDFormatter aligns flash erase boundaries with file
-system structures which reduces write latency and file system overhead.
-
-The PC/Mac SDFormatter does not have an option for FAT type so it may format
-very small cards as FAT12.  Use the SdFat formatter to force FAT16
-formatting of small cards.
-
-Do not format the SD card with an OS utility, OS utilities do not format SD
-cards in conformance with the SD standard.
-
-You should use a freshly formatted SD card for best performance.  FAT
-file systems become slower if many files have been created and deleted.
-This is because the directory entry for a deleted file is marked as deleted,
-but is not deleted.  When a new file is created, these entries must be scanned
-before creating the file.  Also files can become
-fragmented which causes reads and writes to be slower.
-

-SdBaseFile functions.
-
-Many internal changes.
-
-08 Jan 2012
-
-Changes to allow use of the SerialPort library.
-
-Error messages and output from programs are now sent to a stdOut Print
-stream.
-
-The default stdOut is a small non-interrupt driven class that outputs messages
-to serial port zero.  This allows an alternate Serial library like SerialPort
-to be used with SdFat.
-
-You can redirect stdOut with SdFat::setStdOut(Print* stream) and
-get the current stdOut stream with SdFat::stdOut().
-
-If USE_SERIAL_FOR_STD_OUT in SdFatConfig.h is nonzero, the Arduino Serial
-object will be used as the default for stdOut.
-
-
-05 Dec 2011
-
-Changes for Arduino 1.0
-
-
-17 Sep 2011
-
-Changes for Arduino 1.0 beta 4
-
-Improved SPI handling
-
-02 Sep 2011
---------------------------------------------------------------------------------
-Warning:
-Several changes are not backward compatible with the previous
-version of SdFat.
-
-The function cwd() was renamed vwd() to allow multiple SD cards.
-
-The type SdBaseFile was added to the class hierarchy to avoid conflicts with
-other Arduino libraries that are derived from the Print class.  Directory
-files should be declared type SdBaseFile.
---------------------------------------------------------------------------------
-
-Added support for multiple SD cards.
-
-Change the name of SdFat::cwd() to SdFat::vwd() since the volume
-working directory is not the current working directory with
-multiple SD cards.
-
-Added the static function SdBaseFile::cwd() to return a pointer
-to the current working directory.
-
-Added the TwoCards.pde example to demonstrate use of multiple SD cards.
-
-Added readCSV.pde example to demonstrate iostream extractors.
-
-Added bool SdBaseFile::timestamp(SdBaseFile* file) to copy one
-file's timestamps to another file.
-
-Improved messages in the QuickStart.pde example.
-
-Added maximum latency test to the bench.pde example.
-
-Rearanged class hierarchy to fix conflicts with Flash.h and other Adruino
-libraries.  Print is no longer a private parent of file stream classes.
-
-Added high speed multiple block read functions to Sd2Card.
-
-Changed include files in SdFatUtil.h
-
-Removed option to write protect block zero of an SD card.
-
-Changes for Arduino 1.0.
-
-02 Jul 2011
-
-This is a major update based on previous beta versions.
-Read all changes since 10 Oct 2001
-
-Simplified examples in extra/examplesV1
-
-28 Jun 2011

-
-bool SdFat::truncate(const char* path, uint32_t length); 
-
-int16_t SdFile::fgets(char* str, int16_t num, char* delim);
-
-11 May 2011

-Old API maintained for backward compatibility.
-
-
-27 Nov 2010
-
-
-Added experimental support for FAT12.  This can be enabled by setting
-FAT12_SUPPORT nonzero in SdFatConfig.h.
-
-Added an experimental sketch, SdFatFormatter.pde, to format SD cards as
-FAT16 and SDHC cards as FAT32.  See SdFat/examples/SdFormatter.
-
-The return type of SdVolume::cacheClear was changed to cache_t*.
-
-Many internal changes to support FAT12 and formatting SD/SDHC cards.
-
-
-10 Oct 2010
-
-Added Mega 2560.
-
-Fixed rmRfStar() bug.
-
-Fixed Sanguino NULL definition.
-
-18 Aug 2010
-
-Optimized write() for append at end of file.  Up to 50% faster sequential write.
-
-13 Aug 2010
-
-Added the following function to allow the SD chip select pin to be set
-at runtime.  Warning - if the hardware SS pin is not used as chip select, 
-the hardware SS pin will be set to output mode by init(). An avr processor
-will not function as an SPI master unless SS is set to output mode.
-
-uint8_t Sd2Card::init(uint8_t sckRateID, uint8_t chipSelectPin);
-
-Added more SPI clock rate choices.  The above init() function and 
-uint8_t Sd2Card::init(uint8_t sckRateID) call the new function 
-uint8_t Sd2Card::setSckRate(uint8_t sckRateID).
-
-setSckRate() sets the SPI clock rate to F_CPU/pow(2, 1 + sckRateID).
-On an 16 MHz cpu this ranges from 8 MHz for sckRateId = 0 to 125 kHz
-for sckRateID = 6.  This function must be called after the init() call.
-
-Modified most examples to call card.init(SPI_HALF_SPEED) to avoid SPI bus
-errors with breadboards and jumpers.  This sets the SPI speed to F_CPU/4.
-Defined SPI_FULL_SPEED so init(SPI_FULL_SPEED) sets the SPI speed to F_CPU/2.
-
-Added the following  function to cancel date/time callback. This function
-must now be used instead of dateTimeCallback(NULL).
-
-static void SdFat::dateTimeCallbackCancel(void);
-
-
-The following member functions have been added for users who wish to avoid
-calls to functions with non-const references.
-
-uint8_t SdFile::contiguousRange(uint32_t* bgnBlock, uint32_t* endBlock);
-uint8_t SdFile::createContiguous(SdFile* dirFile,
-  const char* fileName, uint32_t size);
-static void SdFile::dateTimeCallback(
-  void (*dateTime)(uint16_t* date, uint16_t* time));
-uint8_t SdFile::dirEntry(dir_t* dir);
-uint8_t SdFile::makeDir(SdFile* dir, const char* dirName);
-uint8_t SdFile::open(SdFile* dirFile, const char* fileName, uint8_t oflag);
-uint8_t SdFile::open(SdFile* dirFile, const char* fileName);
-uint8_t SdFile::open(SdFile* dirFile, uint16_t index, uint8_t oflag);
-uint8_t SdFile::openRoot(SdVolume* vol);
-int8_t SdFile::readDir(dir_t* dir);
-static uint8_t remove(SdFile* dirFile, const char* fileName);
-uint8_t SdVolume::init(Sd2Card* dev);
-uint8_t SdVolume::init(Sd2Card* dev, uint8_t part);
-
-The following member functions have been marked as deprecated since they
-are now wrappers for the new functions. dateTimeCallback is the only wrapper
-with extra overhead.  The other wrappers are squeezed out by the complier.
-These wrappers will be maintained in the future for backward compatibility.
-
-uint8_t SdFile::contiguousRange(uint32_t& bgnBlock, uint32_t& endBlock);
-uint8_t SdFile::createContiguous(SdFile& dirFile,
-  const char* fileName, uint32_t size);
-static void SdFile::dateTimeCallback(
-  void (*dateTime)(uint16_t& date, uint16_t& time));
-uint8_t SdFile::dirEntry(dir_t& dir);
-uint8_t SdFile::makeDir(SdFile& dir, const char* dirName);
-uint8_t SdFile::open(SdFile& dirFile, const char* fileName, uint8_t oflag);
-uint8_t SdFile::open(SdFile& dirFile, const char* fileName);
-uint8_t SdFile::open(SdFile& dirFile, uint16_t index, uint8_t oflag);

-static uint8_t remove(SdFile& dirFile, const char* fileName);
-uint8_t SdVolume::init(Sd2Card& dev);
-uint8_t SdVolume::init(Sd2Card& dev, uint8_t part);
-
-The deprecated function can be disabled by editing SdFat.h and setting
-#define ALLOW_DEPRECATED_FUNCTIONS 0
-
-Fixed file modify time for file rewrite.
-
-Major internal cleanup/reformat based on Google cpplint.py code style.
-
-New Sd2Card::init() algorithm.
-
-New SdFatInfo sketch for modified SdReadData() and other internal changes.
-
-Modified examples to eliminate deprecated functions.
-
-11 Jun 2010
-Added definitions for Teensy to ArduinoPins.h (Paul Stoffregen)
-
-Added troubleshooting.txt
-
-
-23 Dec 2009
-
-Added Software SPI capability.  See Sd2Card.h
-
-Defining MEGA_SOFT_SPI allows an unmodified Adafruit GPS Shield to be used
-on Mega Arduinos.  Software SPI works well with GPS Shield V1.1 
-but many SD cards will fail with GPS Shield V1.0.
-
-Added file ArduinoPins.h for pin definitions.
-
-More error printout in examples.
-
-
-25 Nov 2009
-
-Added new functions for SdFile class:
-
-dateTimeCallback(), dirEntry(), isRoot(), isSubDir, ls(), 
-makeDir(), printDirName(), printFatDate(), printFatTime(), 
-printTwoDigits(), rmDir(), and rmRStar().
-
-Added new examples to test and illustrate use of new functions.
-
-Removed sdCard() from SdFile class.
-
-Fixed several bugs.
-
-
-
-
-12 Nov 2009
-
-Major rewrite of the version of SdFat that was included with
-the WaveRP library.  
-
-This is a preview that is being released to obtain comments
-from several colleagues and future users.

- * \defgroup asfdoc_sam0_system_clock_group SAM System Clock Management Driver (SYSTEM CLOCK)
- *
- * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides an interface for the configuration
- * and management of the device's clocking related functions. This includes
- * the various clock sources, bus clocks, and generic clocks within the device,
- * with functions to manage the enabling, disabling, source selection, and
- * prescaling of clocks to various internal peripherals.
- *
- * The following peripherals are used by this module:
- *
- * - GCLK (Generic Clock Management)
- * - PM (Power Management)
- * - SYSCTRL (Clock Source Control)
- *
- * The following devices can use this module:
- *  - Atmel | SMART SAM D20/D21
- *  - Atmel | SMART SAM R21
- *  - Atmel | SMART SAM D10/D11
- *  - Atmel | SMART SAM DA0/DA1
- *

- *
- * \section asfdoc_sam0_system_clock_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_clock_module_overview Module Overview
- * The SAM devices contain a sophisticated clocking system, which is designed
- * to give the maximum flexibility to the user application. This system allows
- * a system designer to tune the performance and power consumption of the device
- * in a dynamic manner, to achieve the best trade-off between the two for a
- * particular application.
- *
- * This driver provides a set of functions for the configuration and management
- * of the various clock related functionality within the device.

- *		<td>FEATURE_SYSTEM_CLOCK_DPLL</td>
- *		<td>SAMD21, SAMR21, SAMD10, SAMD11, SAMDAx</td>
- *	</tr>
- * </table>
- * \note The specific features are only available in the driver when the
- * selected device supports those features.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_clock_sources Clock Sources
- * The SAM devices have a number of master clock source modules, each of
- * which being capable of producing a stabilized output frequency, which can then
- * be fed into the various peripherals and modules within the device.
- *
- * Possible clock source modules include internal R/C oscillators, internal
- * DFLL modules, as well as external crystal oscillators and/or clock inputs.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_cpu_clock CPU / Bus Clocks
- * The CPU and AHB/APBx buses are clocked by the same physical clock source
- * (referred in this module as the Main Clock), however the APBx buses may
- * have additional prescaler division ratios set to give each peripheral bus a
- * different clock speed.
- *
- * The general main clock tree for the CPU and associated buses is shown in
- * \ref asfdoc_sam0_system_clock_module_clock_tree "the figure below".

- *
- * \subsection asfdoc_sam0_system_clock_module_overview_clock_masking Clock Masking
- * To save power, the input clock to one or more peripherals on the AHB and APBx
- * buses can be masked away - when masked, no clock is passed into the module.
- * Disabling of clocks of unused modules will prevent all access to the masked
- * module, but will reduce the overall device power consumption.
- *
- * \subsection asfdoc_sam0_system_clock_module_overview_gclk Generic Clocks
- * Within the SAM devices there are a number of Generic Clocks; these are used to
- * provide clocks to the various peripheral clock domains in the device in a
- * standardized manner. One or more master source clocks can be selected as the
- * input clock to a Generic Clock Generator, which can prescale down the input
- * frequency to a slower rate for use in a peripheral.
- *
- * Additionally, a number of individually selectable Generic Clock Channels are
- * provided, which multiplex and gate the various generator outputs for one or
- * more peripherals within the device. This setup allows for a single common
- * generator to feed one or more channels, which can then be enabled or disabled
- * individually as required.

- * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_generators Generic Clock Generators
- * Each Generic Clock generator within the device can source its input clock
- * from one of the provided Source Clocks, and prescale the output for one or
- * more Generic Clock Channels in a one-to-many relationship. The generators
- * thus allow for several clocks to be generated of different frequencies,
- * power usages, and accuracies, which can be turned on and off individually to
- * disable the clocks to multiple peripherals as a group.
- *
- * \subsubsection asfdoc_sam0_system_clock_module_overview_gclk_channels Generic Clock Channels
- * To connect a Generic Clock Generator to a peripheral within the
- * device, a Generic Clock Channel is used. Each peripheral or
- * peripheral group has an associated Generic Clock Channel, which serves as the
- * clock input for the peripheral(s). To supply a clock to the peripheral
- * module(s), the associated channel must be connected to a running Generic
- * Clock Generator and the channel enabled.

- *
- * \section asfdoc_sam0_i2s_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- * \section asfdoc_sam0_i2s_module_overview Module Overview
- *
- * The I2S provides bidirectional, synchronous, digital audio link with external
- * audio devices through these signal pins:
- *  - Serial Data (SDm)
- *  - Frame Sync (FSn)
- *  - Serial Clock (SCKn)
- *  - Master Clock (MCKn)
- *
- * The I2S consists of 2 Clock Units and 2 Serializers, which can be separately
- * configured and enabled, to provide varies functionalities as follow:
- *  - Communicate to Audio CODECs as Master or Slave, or provides clock and
- *    frame sync signals as Controller
- *  - Communicate to DAC or ADC through dedicated I2S serial interface
- *  - Communicate to multi-slot or multiple stereo DACs or ADCs, via
- *    Time Division Multiplexed (TDM) format
- *  - Reading mono or stereo MEMS microphones, using the Pulse Density
- *    Modulation (PDM) interface
- *
- * The I2S supports compact stereo data word, where left channel data bits are
- * in lower half and right channel data bits are in upper half. It reduces the
- * number of data words for stereo audio data and the DMA bandwidth.
- *
- * In master mode, the frame is configured by number of slots and slot size, and
- * allows range covering 16fs to 1024fs MCK, to provide oversampling clock to an
- * external audio CODEC or digital signal processor (DSP).
- *
- * A block diagram of the I2S can be seen in
- * \ref asfdoc_sam0_i2s_module_block_diagram "the figure below".
- *
- * \anchor asfdoc_sam0_i2s_module_block_diagram
- * \image html i2s_blocks.svg "I2S Block Diagram"
- *
- * This driver for I2S module provides an interface to
- *  - initialize and control I2S module
- *  - configure and control the I2S Clock Unit and Serializer
- *  - transmit/receive data through I2S Serializer
- *
- * \subsection asfdoc_sam0_i2s_module_overview_clocks Clocks
- *
- * To use I2S module, the I2S bus interface clock (clk_i2s) must be enabled via
- * Power Manager.
- *
- * For each I2S Clock Unit, a generic clock (gclk_i2s_n) is connnected. When I2S
- * works in master mode the generic clock is used. It should be prepared before
- * clock unit is used. In master mode the input generic clock will be used as
- * MCK for SCKn and FSn generation, in addition, the MCK could be devided and
- * output to I2S MCKn pin, as oversampling clock to external audio device.
- *
- * The I2S Serializer uses clock and control signal from Clock Unit to handle
- * transfer. Select different clock unit with different configurations allows
- * the I2S to work as master or slave, to work on non-related clocks.
- *
- * When using the driver with ASF, enabling the register interface is normally
- * done by the \c init function.
- * The gclk source for the asynchronous domain is normally configured and set
- * through the _configuration struct_ / _init_ function. 
- * If gclk source != 0 is used, this source has to be configured and enabled
- * through invoking the system_gclk driver function when needed, or modifying
- * conf_clock.h to enable it at the beginning.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_frame Audio Frame Generation
- *
- * Audio sample data for all channels are sent in frames, one frame can consist
- * 1 - 8 slots where each slot can be configured to a size 8-bit, 16-bit, 24-bit
- * or 32-bit. The audio frame synch clock is generated by the I2S Clock unit in
- * the master/controller mode. The frame rate (or frame sync frequency) is
- * calculated as follow:
- *
- * FS = SCK / number_of_slots / number_of_bits_in_slot
- *
- * The serial clock (SCK) source is either an external source (slave mode) or
- * generated by the I2S clock unit (controller or master mode) using the MCK as
- * source.
- *
- * SCK = MCK / sck_div
- * \note SCK generation division value is MCKDIV in register.
- *
- * MCK is either an external source or generated using the gclk input from a
- * generic clock generator.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_mode Master, Controller and Slave modes
- *
- * The i2s module has three modes: master, controller and slave.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_mst Master
- * In master mode the module will control the data flow on the i2s bus and can
- * be responsible for clock generation. The Serializers are enabled and will
- * transmit/receive data. On a bus with only master and slave the SCK and FS
- * clock signal will be outputted on the SCK and FS pin on the master module.
- * MCK can optionally be outputted on the MCK pin, if there is a controller
- * module on the bus the SCK, FS and optionally the MCK clock is sourced from
- * the same pins. Serial data will be trancieved on the SD pin in both
- * scenarios.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_ctl Controller
- * In controller mode the module will generate the clock signals, but the
- * Serializers are disabled and no data will be transmitted/received by the
- * module in this mode. The clock signals is outputted on the SCK, FS and
- * optionally the MCK pin.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_slv Slave
- * In slave mode the module will use the SCK and FS clock source from the master
- * or the controller which is received on the SCK and FS pin. The MCK can
- * optionally be sourced externally on the MCK pin. The Serializers are enabled
- * and will tranceive data on the SD pin. All data flow is controlled by the
- * master.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_mode_chg Switch modes
- * The mode switching between master, controller and slave modes are actually
- * done by modifying the source mode of I2S pins.
- * The source mode of I2S pins are selected by writing corresponding bits in
- * CLKCTRLn.
- * Since source mode switching changes the direction of pin, the mode must be
- * changed when the I2S Clock Unit is stopped.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_data Data Stream Reception/Transmission
- *
- * The I2S module support several data stream formats:
- * - I2S format
- * - Time Division Multiplexed (TDM) format
- * - Pulse Density Modulation (PDM) format (reception only)
- *
- * Basically the I2S module can send several words within each frame, it's more
- * like TDM format. With adjust to the number of data words in a frame, the FS
- * width, the FS to data bits delay, etc., the module is able to handle I2S
- * compliant data stream.
- *
- * Also the Serializer can receive PDM format data stream, which allows the I2S
- * module receive 1 PDM data on each SCK edge.
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_i2s I2S Stream Reception/Transmission
- *
- * For 2-channel I2S compliant data stream format the i2s module uses the FS
- * line as word select (WS) signal and will send left channel data word on low
- * WS level and right channel data word on high WS level as specified in the I2S
- * standard. The supported word sizes are 8-, 16-, 18-, 20-, 24- and 32- bit.
- *
- * Thus for I2S stream, the following settings should be applied to the module:
- *  - Data starting delay after FS transition : one SCK period
- *  - FS width : half of frame
- *  - Data bits adjust in word : left-adjusted
- *  - Bit transmitting order : MSB first
- *
- * Following is an example for I2S application connections and waveforms. See
- * \ref asfdoc_sam0_i2s_module_i2s_example_diagram "the figure below".
- *
- * \anchor asfdoc_sam0_i2s_module_i2s_example_diagram
- * \image html i2s_example.svg "I2S Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_tdm TDM Stream Reception/Transmission
- * In TDM format, the module sends several data words in each frame. For this
- * data stream format most of the configurations could be adjusted:
- *  - Main Frame related settings are as follow:
- *   - Frame Sync (FS) options:
- *    - the active edge of the FS (or if FS is inverted before use)
- *    - the width of the FS
- *   - the delay between FS to first data bit
- *  - Data alignment in slot
- *  - The number of slots and slot size can be adjusted, it has been mentioned
- *    in \ref asfdoc_sam0_i2s_module_overview_frame
- *  - The data word size is controlled by Serializer, it can be chosen among
- *    8, 16, 18, 20, 24 and 32 bits.
- *
- * The general TDM waveform generation is as follow:
- *
- * \anchor asfdoc_sam0_i2s_module_tdm_wave_diagram
- * \image html tdm_wave.svg "TDM Waveform generation"
- *
- * Some other settings could also be found to set up clock, data formatting and
- * pin mux.
- * refer to \ref i2s_clock_unit_config "Clock Unit Configurations"
- * and \ref i2s_serializer_config "Serializer Configurations" for more
- * details.
- *
- * Following is examples for different application use cases.
- *
- * See \ref asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram "here" for
- * the Time Slot Application connection and waveform example.
- *
- * \anchor asfdoc_sam0_i2s_module_tdm_timeslot_example_diagram

- * \image html tdm_codec_example.svg "Time Slot Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_pdm PDM Reception
- * The I2S Serializer integrates PDM reception feature, to use this feature,
- * simply select PDM2 mode in Serializer configuration. In PDM2 mode, it assumes
- * two microphones are input for stereo stream. The left microphone bits will
- * be stored in lower half and right microphone bits in upper half of the data
- * word, like in compact stereo format.
- *
- * See \ref asfdoc_sam0_i2s_module_pdm_example_diagram "following figure" for an
- * example of PDM Microphones Application with both left and right channel
- * microphone connected.
- *
- * \anchor asfdoc_sam0_i2s_module_pdm_example_diagram
- * \image html pdm_example.svg "Time PDM2 Example Diagram"
- *
- * \subsubsection asfdoc_sam0_i2s_module_overview_data_fmt MONO and Compact Data
- * The I2S Serializer can accept some pre-defined data format and generates
- * the data stream in specified way.
- *
- * When transmitting data, the Serializer can work in MONO mode: assum input
- * is single channel mono data on left channel and copy it to right channel
- * automatically.
- *
- * Also the I2S Serializer can support compact stereo data word. The data word
- * size of the Serializer can be set to \ref I2S_DATA_SIZE_16BIT_COMPACT
- * "16-bit compact" or \ref I2S_DATA_SIZE_8BIT_COMPACT "8-bit compact", with
- * these option I2S Serializer will compact left channel data and right channel
- * data together, the left channel data will take lower bytes and right channel
- * data take higher bytes.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_loop Loop-back Mode
- * The I2S can be configured to loop back the Transmitter to Receiver. In this
- * mode Serializer's input will be connected to another Serializer's output
- * internally.
- *
- * \subsection asfdoc_sam0_i2s_module_overview_sleep Sleep Modes
- * The I2S will continue to operate in any sleep mode, where the selected source
- * clocks are running.
- *
- * \section asfdoc_sam0_i2s_special_considerations Special Considerations
- *
- * There is no special considerations for I2S module.

-/**
- * \defgroup asfdoc_sam0_system_pinmux_group SAM System Pin Multiplexer (SYSTEM PINMUX) Driver
- *
- * This driver for Atmel&reg; | SMART ARM&reg;-based microcontrollers provides
- * an interface for the configuration and management of the device's physical
- * I/O Pins, to alter the direction and input/drive characteristics as well as
- * to configure the pin peripheral multiplexer selection.
- *
- * The following peripheral is used by this module:
- *  - PORT (Port I/O Management)
- *
- * The following devices can use this module:
- *  - Atmel | SMART SAM D20/D21
- *  - Atmel | SMART SAM R21
- *  - Atmel | SMART SAM D09/D10/D11
- *  - Atmel | SMART SAM L21/L22
- *  - Atmel | SMART SAM DA1
- *  - Atmel | SMART SAM C20/C21
- *
- * Physically, the modules are interconnected within the device as shown in the
- * following diagram:
- *
- * The outline of this documentation is as follows:
- *  - \ref asfdoc_sam0_system_pinmux_prerequisites
- *  - \ref asfdoc_sam0_system_pinmux_module_overview
- *  - \ref asfdoc_sam0_system_pinmux_special_considerations
- *  - \ref asfdoc_sam0_system_pinmux_extra_info

- *  - \ref asfdoc_sam0_system_pinmux_api_overview
- *
- *
- * \section asfdoc_sam0_system_pinmux_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_pinmux_module_overview Module Overview
- *
- * The SAM devices contain a number of General Purpose I/O pins, used to
- * interface the user application logic and internal hardware peripherals to
- * an external system. The Pin Multiplexer (PINMUX) driver provides a method
- * of configuring the individual pin peripheral multiplexers to select
- * alternate pin functions.
- *
- * \subsection asfdoc_sam0_system_pinmux_features Driver Feature Macro Definition
- * <table>
- *  <tr>
- *    <th>Driver Feature Macro</th>
- *    <th>Supported devices</th>
- *  </tr>
- *  <tr>
- *    <td>FEATURE_SYSTEM_PINMUX_DRIVE_STRENGTH</td>
- *    <td>SAM L21, SAM C20/C21</td>
- *  </tr>
- * </table>
- * \note The specific features are only available in the driver when the
- * selected device supports those features.
- *
- * \subsection asfdoc_sam0_system_pinmux_physical_logical_pins Physical and Logical GPIO Pins
- * SAM devices use two naming conventions for the I/O pins in the device; one
- * physical and one logical. Each physical pin on a device package is assigned
- * both a physical port and pin identifier (e.g. "PORTA.0") as well as a
- * monotonically incrementing logical GPIO number (e.g. "GPIO0"). While the
- * former is used to map physical pins to their physical internal device module
- * counterparts, for simplicity the design of this driver uses the logical GPIO
- * numbers instead.
- *
- * \subsection asfdoc_sam0_system_pinmux_peripheral_muxing Peripheral Multiplexing
- * SAM devices contain a peripheral MUX, which is individually controllable
- * for each I/O pin of the device. The peripheral MUX allows you to select the
- * function of a physical package pin - whether it will be controlled as a user
- * controllable GPIO pin, or whether it will be connected internally to one of
- * several peripheral modules (such as an I<SUP>2</SUP>C module). When a pin is
- * configured in GPIO mode, other peripherals connected to the same pin will be
- * disabled.
- *
- * \subsection asfdoc_sam0_system_pinmux_pad_characteristics Special Pad Characteristics
- * There are several special modes that can be selected on one or more I/O pins
- * of the device, which alter the input and output characteristics of the pad.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_drive_strength Drive Strength
- * The Drive Strength configures the strength of the output driver on the
- * pad. Normally, there is a fixed current limit that each I/O pin can safely
- * drive, however some I/O pads offer a higher drive mode which increases this
- * limit for that I/O pin at the expense of an increased power consumption.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_slew_rate Slew Rate
- * The Slew Rate configures the slew rate of the output driver, limiting the
- * rate at which the pad output voltage can change with time.
- *
- * \subsubsection asfdoc_sam0_system_pinmux_input_sample_mode Input Sample Mode
- * The Input Sample Mode configures the input sampler buffer of the pad. By
- * default, the input buffer is only sampled "on-demand", i.e. when the user
- * application attempts to read from the input buffer. This mode is the most
- * power efficient, but increases the latency of the input sample by two clock
- * cycles of the port clock. To reduce latency, the input sampler can instead
- * be configured to always sample the input buffer on each port clock cycle, at
- * the expense of an increased power consumption.
- *
- * \subsection asfdoc_sam0_system_pinmux_module_overview_physical Physical Connection
- *
- * \ref asfdoc_sam0_system_pinmux_intconnections "The diagram below" shows
- * how this module is interconnected within the device:
- *
- * \anchor asfdoc_sam0_system_pinmux_intconnections

- *     node [label="Other Peripheral Modules" shape=ellipse style=filled fillcolor=lightgray] peripherals;
- *   }
- *
- *   pinmux -> gpio;
- *   pad    -> pinmux;
- *   pinmux -> peripherals;
- * }
- * \enddot
- *
- * \section asfdoc_sam0_system_pinmux_special_considerations Special Considerations
- *
- * The SAM port pin input sampling mode is set in groups of four physical
- * pins; setting the sampling mode of any pin in a sub-group of eight I/O pins
- * will configure the sampling mode of the entire sub-group.
- *
- * High Drive Strength output driver mode is not available on all device pins -
- * refer to your device specific datasheet.

- * a number of sub-modules that control one specific aspect of the device:
- *
- * - System Core (this module)
- * - \ref asfdoc_sam0_system_clock_group "System Clock Control" (sub-module)
- * - \ref asfdoc_sam0_system_interrupt_group "System Interrupt Control" (sub-module)

- *
- *
- * \if DEVICE_SAML21_SYSTEM_SUPPORT
- * \subsection asfdoc_sam0_system_module_overview_vreg_l21 Voltage Regulator
- * The SAM device controls the voltage regulators for the core (VDDCORE) and
- * backup (VDDBU) domains. It sets the voltage regulators according to the sleep
- * modes, the performance level, or the user configuration.
- *
- * In active mode, the voltage regulator can be chosen on the fly between a LDO
- * or a Buck converter. In standby mode, the low power voltage regulator is used
- * to supply VDDCORE.
- *
- * \subsection asfdoc_sam0_system_module_overview_bbps Battery Backup Power Switch
- * The SAM device supports connection of a battery backup to the VBAT power pin.
- * It includes functionality that enables automatic power switching between main
- * power and battery backup power. This will ensure power to the backup domain,
- * when the main battery or power source is unavailable.
- * \endif
- *
- * \if DEVICE_SAMC21_SYSTEM_SUPPORT
- * \subsection asfdoc_sam0_system_module_overview_vreg_c21 Voltage Regulator
- * The SAM device controls the voltage regulators for the core (VDDCORE). It sets
- * the voltage regulators according to the sleep modes.
- *
- * There are a selectable reference voltage and voltage dependent on the temperature
- * which can be used by analog modules like the ADC.
- * \endif
- *
- * \subsection asfdoc_sam0_system_module_overview_vref Voltage References
- * The various analog modules within the SAM devices (such as AC, ADC, and
- * DAC) require a voltage reference to be configured to act as a reference point
- * for comparisons and conversions.
- *
- * The SAM devices contain multiple references, including an internal
- * temperature sensor and a fixed band-gap voltage source. When enabled, the
- * associated voltage reference can be selected within the desired peripheral
- * where applicable.
- *
- * \subsection asfdoc_sam0_system_module_overview_reset_cause System Reset Cause
- * In some applications there may be a need to execute a different program
- * flow based on how the device was reset. For example, if the cause of reset
- * was the Watchdog timer (WDT), this might indicate an error in the application,
- * and a form of error handling or error logging might be needed.
- *
- * For this reason, an API is provided to retrieve the cause of the last system
- * reset, so that appropriate action can be taken.
- *
- * \if DEVICE_SAML21_SYSTEM_SUPPORT
- * There are three groups of reset sources:
- *   - Power supply reset: Resets caused by an electrical issue. It covers POR and BOD reset.
- *   - User reset: Resets caused by the application. It covers external reset,
- *             system reset, and watchdog reset.
- *   - Backup reset: Resets caused by a backup mode exit condition.
- *
- * \subsection asfdoc_sam0_system_module_overview_performance_level Performance Level
- * Performance level allows the user to adjust the regulator output voltage to reduce
- * power consumption. The user can on the fly select the most suitable performance
- * level, depending on the application demands.
- *
- * The SAM device can operate at two different performance levels (PL0 and PL2).
- * When operating at PL0, the voltage applied on the full logic area is reduced
- * by voltage scaling. This voltage scaling technique allows to reduce the active
- * power consumption while decreasing the maximum frequency of the device. When
- * operating at PL2, the voltage regulator supplies the highest voltage, allowing
- * the device to run at higher clock speeds.
- *
- * Performance level transition is possible only when the device is in active
- * mode. After a reset, the device starts at the lowest performance level
- * (lowest power consumption and lowest max. frequency). The application can then
- * switch to another performance level at any time without any stop in the code
- * execution. As shown in \ref asfdoc_sam0_system_performance_level_transition_figure.
- *
- * \note When scaling down the performance level, the bus frequency should first be
- *  scaled down in order to not exceed the maximum frequency allowed for the
- *  low performance level.
- *  When scaling up the performance level (e.g. from PL0 to PL2), check the performance
- *  level status before increasing the bus frequency. It can be increased only
- *  when the performance level transition is completed.

- *
- * \subsection asfdoc_sam0_system_module_overview_power_domain Power Domain Gating
- * Power domain gating allows power saving by reducing the voltage in logic
- * areas in the device to a low-power supply. The feature is available in
- * Standby sleep mode and will reduce the voltage in domains where all peripherals
- * are idle. Internal logic will maintain its content, meaning the corresponding
- * peripherals will not need to be reconfigured when normal operating voltage
- * is returned. Most power domains can be in the following three states:
- *
- * - Active state: The power domain is powered on.
- * - Retention state: The main voltage supply for the power domain is switched off,
- * while maintaining a secondary low-power supply for the sequential cells. The
- * logic context is restored when waking up.
- * - Off state: The power domain is entirely powered off. The logic context is lost.
- *
- * The SAM L21 device  contains three power domains which can be controlled using
- * power domain gating, namely PD0, PD1, and PD2. These power domains can be
- * configured to the following cases:
- * - Default with no sleepwalking peripherals: A power domain is automatically set
- * to retention state in standby sleep mode if no activity require it. The application
- * can force all power domains to remain in active state during standby sleep mode
- * in order to accelerate wakeup time.
- * - Default with sleepwalking peripherals: If one or more peripherals are enabled
- * to perform sleepwalking tasks in standby sleep mode, the corresponding power
- * domain (PDn) remains in active state as well as all inferior power domains (<PDn).
- * - Sleepwalking with dynamic power domain gating: During standby sleep mode, a
- * power domain (PDn) in active can wake up a superior power domain (>PDn) in order
- * to perform a sleepwalking task. The superior power domain is then automatically
- * set to active state. At the end of the sleepwalking task, the device can either
- * be woken up or the superior power domain can return to retention state.
- *
- * Power domains can be linked to each other, it allows a power domain (PDn) to be kept
- * in active state if the inferior power domain (PDn-1) is in active state too.
- *
- * \ref asfdoc_sam0_system_power_domain_overview_table illustrates the
- * four cases to consider in standby mode.

- *
- * \section asfdoc_sam0_system_interrupt_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_system_interrupt_module_overview Module Overview
- *
- * The ARM&reg; Cortex&reg; M0+ core contains an interrupt and exception vector table, which
- * can be used to configure the device's interrupt handlers; individual
- * interrupts and exceptions can be enabled and disabled, as well as configured
- * with a variable priority.
- *
- * This driver provides a set of wrappers around the core interrupt functions,
- * to expose a simple API for the management of global and individual interrupts
- * within the device.
- *
- * \subsection asfdoc_sam0_system_interrupt_module_overview_criticalsec Critical Sections
- * In some applications it is important to ensure that no interrupts may be
- * executed by the system whilst a critical portion of code is being run; for
- * example, a buffer may be copied from one context to another - during which
- * interrupts must be disabled to avoid corruption of the source buffer contents
- * until the copy has completed. This driver provides a basic API to enter and
- * exit nested critical sections, so that global interrupts can be kept disabled
- * for as long as necessary to complete a critical application code section.
- *
- * \subsection asfdoc_sam0_system_interrupt_module_overview_softints Software Interrupts
- * For some applications, it may be desirable to raise a module or core
- * interrupt via software. For this reason, a set of APIs to set an interrupt or
- * exception as pending are provided to the user application.
- *
- * \section asfdoc_sam0_system_interrupt_special_considerations Special Considerations
- *
- * Interrupts from peripherals in the SAM devices are on a per-module basis;
- * an interrupt raised from any source within a module will cause a single,
- * module-common handler to execute. It is the user application or driver's
- * responsibility to de-multiplex the module-common interrupt to determine the
- * exact interrupt cause.
- *
- * \section asfdoc_sam0_system_interrupt_extra_info Extra Information

- *
- * \section asfdoc_sam0_tc_module_overview Module Overview
- *
- * The Timer/Counter (TC) module provides a set of timing and counting related
- * functionality, such as the generation of periodic waveforms, the capturing
- * of a periodic waveform's frequency/duty cycle, and software timekeeping for
- * periodic operations. TC modules can be configured to use an 8-, 16-, or
- * 32-bit counter size.
- *
- * This TC module for the SAM is capable of the following functions:
- *
- * - Generation of PWM signals
- * - Generation of timestamps for events
- * - General time counting
- * - Waveform period capture
- * - Waveform frequency capture
- *
- * \ref asfdoc_sam0_tc_block_diagram "The diagram below" shows the overview

- *
- * \subsection asfdoc_sam0_tc_module_overview_func_desc Functional Description
- * Independent of the configured counter size, each TC module can be set up
- * in one of two different modes; capture and compare.
- *
- * In capture mode, the counter value is stored when a configurable event
- * occurs. This mode can be used to generate timestamps used in event capture,
- * or it can be used for the measurement of a periodic input signal's
- * frequency/duty cycle.
- *
- * In compare mode, the counter value is compared against one or more of the
- * configured channel compare values. When the counter value coincides with a
- * compare value an action can be taken automatically by the module, such as
- * generating an output event or toggling a pin when used for frequency or PWM
- * signal generation.
- *
- * \note The connection of events between modules requires the use of the
- *       \ref asfdoc_sam0_events_group "SAM Event System Driver (EVENTS)"
- *       to route output event of one module to the input event of another.
- *       For more information on event routing, refer to the event driver
- *       documentation.
- *
- * \subsection asfdoc_sam0_tc_module_overview_tc_size Timer/Counter Size
- * Each timer module can be configured in one of three different counter
- * sizes; 8-, 16-, and 32-bit. The size of the counter determines the maximum
- * value it can count to before an overflow occurs and the count is reset back
- * to zero. \ref asfdoc_sam0_tc_count_size_vs_top "The table below" shows the
- * maximum values for each of the possible counter sizes.
- *
- * \anchor asfdoc_sam0_tc_count_size_vs_top
- * <table>
- *  <caption>Timer Counter Sizes and Their Maximum Count Values</caption>
- *  <tr>
- *    <th>Counter size</th>
- *    <th>Max. (hexadecimal)</th>
- *    <th>Max. (decimal)</th>
- *  </tr>
- *  <tr>
- *    <td>8-bit</td>
- *    <td>0xFF</td>
- *    <td>255</td>
- *  </tr>
- *  <tr>
- *    <td>16-bit</td>
- *    <td>0xFFFF</td>
- *    <td>65,535</td>
- *  </tr>
- *  <tr>
- *    <td>32-bit</td>
- *    <td>0xFFFFFFFF</td>
- *    <td>4,294,967,295</td>
- *  </tr>
- * </table>
- *
- * When using the counter in 16- or 32-bit count mode, Compare Capture
- * register 0 (CC0) is used to store the period value when running in PWM
- * generation match mode.
- *
- * When using 32-bit counter size, two 16-bit counters are chained together
- * in a cascade formation. Except in SAM D09/D10/D11, Even numbered TC modules
- * (e.g. TC0, TC2) can be configured as 32-bit counters. The odd numbered
- * counters will act as slaves to the even numbered masters, and will not
- * be reconfigurable until the master timer is disabled. The pairing of timer
- * modules for 32-bit mode is shown in \ref asfdoc_sam0_tc_module_ms_pairs
- * "the table below".
- *
- * \anchor asfdoc_sam0_tc_module_ms_pairs
- * <table>

- *     <th>Master TC Module</th>

- *   </tr>
- *   <tr>
- *     <td>TCn-1</td>
- *     <td>TCn</td>
- *   </tr>
- * </table>
- *
- * In SAM D09/D10/D11, odd numbered TC modules (e.g. TC1) can be configured as 32-bit
- * counters. The even numbered(e.g. TC2) counters will act as slaves to the odd
- * numbered masters.
- *
- * \subsection asfdoc_sam0_tc_module_overview_clock Clock Settings
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_selection Clock Selection
- * Each TC peripheral is clocked asynchronously to the system clock by a GCLK
- * (Generic Clock) channel. The GCLK channel connects to any of the GCLK
- * generators. The GCLK generators are configured to use one of the available
- * clock sources on the system such as internal oscillator, external crystals,
- * etc. see the \ref asfdoc_sam0_system_clock_group "Generic Clock driver"
- *for
- * more information.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_prescaler Prescaler
- * Each TC module in the SAM has its own individual clock prescaler, which
- * can be used to divide the input clock frequency used in the counter. This
- * prescaler only scales the clock used to provide clock pulses for the counter
- * to count, and does not affect the digital register interface portion of
- * the module, thus the timer registers will synchronize to the raw GCLK
- * frequency input to the module.
- *
- * As a result of this, when selecting a GCLK frequency and timer prescaler
- * value the user application should consider both the timer resolution
- * required and the synchronization frequency, to avoid lengthy
- * synchronization times of the module if a very slow GCLK frequency is fed
- * into the TC module. It is preferable to use a higher module GCLK frequency
- * as the input to the timer, and prescale this down as much as possible to
- * obtain a suitable counter frequency in latency-sensitive applications.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_clock_reloading Reloading
- * Timer modules also contain a configurable reload action, used when a
- * re-trigger event occurs. Examples of a re-trigger event are the counter
- * reaching the maximum value when counting up, or when an event from the event
- * system tells the counter to re-trigger. The reload action determines if the
- * prescaler should be reset, and when this should happen. The counter will
- * always be reloaded with the value it is set to start counting from. The user
- * can choose between three different reload actions, described in
- * \ref asfdoc_sam0_tc_module_reload_act "the table below".
- *
- * \anchor asfdoc_sam0_tc_module_reload_act
- * <table>
- *   <caption>TC Module Reload Actions</caption>
- *   <tr>
- *     <th>Reload action</th>
- *     <th>Description</th>
- *   </tr>
- *   <tr>
- *     <td>\ref TC_RELOAD_ACTION_GCLK </td>
- *     <td>Reload TC counter value on next GCLK cycle. Leave prescaler
- *         as-is.</td>
- *   </tr>
- *   <tr>
- *     <td>\ref TC_RELOAD_ACTION_PRESC </td>
- *     <td>Reloads TC counter value on next prescaler clock. Leave prescaler
- *         as-is.</td>
- *   </tr>
- *  <tr>
- *    <td> \ref TC_RELOAD_ACTION_RESYNC </td>
- *    <td>Reload TC counter value on next GCLK cycle. Clear prescaler to
- *        zero.</td>
- *  </tr>
- * </table>
- *
- * The reload action to use will depend on the specific application being
- * implemented. One example is when an external trigger for a reload occurs; if
- * the TC uses the prescaler, the counter in the prescaler should not have a
- * value between zero and the division factor. The TC counter and the counter
- * in the prescaler should both start at zero. When the counter is set to
- * re-trigger when it reaches the maximum value on the other hand, this is not the
- * right option to use. In such a case it would be better if the prescaler is
- * left unaltered when the re-trigger happens, letting the counter reset on the
- * next GCLK cycle.
- *
- * \subsection asfdoc_sam0_tc_module_overview_compare_match Compare Match Operations
- * In compare match operation, Compare/Capture registers are used in comparison
- * with the counter value. When the timer's count value matches the value of a
- * compare channel, a user defined action can be taken.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_timer Basic Timer
- *
- * A Basic Timer is a simple application where compare match operations is used
- * to determine when a specific period has elapsed. In Basic Timer operations,
- * one or more values in the module's Compare/Capture registers are used to
- * specify the time (as a number of prescaled GCLK cycles) when an action should
- * be taken by the microcontroller. This can be an Interrupt Service Routine
- * (ISR), event generator via the event system, or a software flag that is
- * polled via the user application.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg Waveform Generation
- *
- * Waveform generation enables the TC module to generate square waves, or if
- * combined with an external passive low-pass filter; analog waveforms.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_pwm Waveform Generation - PWM
- *
- * Pulse width modulation is a form of waveform generation and a signalling
- * technique that can be useful in many situations. When PWM mode is used,
- * a digital pulse train with a configurable frequency and duty cycle can be
- * generated by the TC module and output to a GPIO pin of the device.
- *
- * Often PWM is used to communicate a control or information parameter to an
- * external circuit or component. Differing impedances of the source generator
- * and sink receiver circuits is less of an issue when using PWM compared to
- * using an analog voltage value, as noise will not generally affect the
- * signal's integrity to a meaningful extent.
- *
- * \ref asfdoc_sam0_tc_module_pwm_normal_diag "The figure below" illustrates
- * operations and different states of the counter and its output when running
- * the counter in PWM normal mode. As can be seen, the TOP value is unchanged
- * and is set to MAX. The compare match value is changed at several points to
- * illustrate the resulting waveform output changes. The PWM output is set to
- * normal (i.e. non-inverted) output mode.
- *
- * \anchor asfdoc_sam0_tc_module_pwm_normal_diag
- * \image html pwm_normal_ex.svg "Example of PWM in Normal Mode, and Different Counter Operations"
- *
- *
- * In \ref asfdoc_sam0_tc_module_pwm_match_diag "the figure below", the
- * counter is set to generate PWM in Match mode. The PWM output is inverted via
- * the appropriate configuration option in the TC driver configuration
- * structure. In this example, the counter value is changed once, but the
- * compare match value is kept unchanged. As can be seen, it is possible to
- * change the TOP value when running in PWM match mode.
- *
- * \anchor asfdoc_sam0_tc_module_pwm_match_diag
- * \image html pwm_match_ex.svg "Example of PWM in Match Mode, and Different Counter Operations"
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_wg_freq Waveform Generation - Frequency
- *
- * Frequency Generation mode is in many ways identical to PWM
- * generation. However, in Frequency Generation a toggle only occurs
- * on the output when a match on a capture channels occurs. When the
- * match is made, the timer value is reset, resulting in a variable
- * frequency square wave with a fixed 50% duty cycle.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt Capture Operations
- *
- * In capture operations, any event from the event system or a pin change can
- * trigger a capture of the counter value. This captured counter value can be
- * used as a timestamp for the event, or it can be used in frequency and pulse
- * width capture.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_event_capture Capture Operations - Event
- *
- * Event capture is a simple use of the capture functionality,
- * designed to create timestamps for specific events. When the TC
- * module's input capture pin is externally toggled, the current timer
- * count value is copied into a buffered register which can then be
- * read out by the user application.
- *
- * Note that when performing any capture operation, there is a risk that the
- * counter reaches its top value (MAX) when counting up, or the bottom value
- * (zero) when counting down, before the capture event occurs. This can distort
- * the result, making event timestamps to appear shorter than reality; the
- * user application should check for timer overflow when reading a capture
- * result in order to detect this situation and perform an appropriate
- * adjustment.
- *
- * Before checking for a new capture, \ref TC_STATUS_COUNT_OVERFLOW
- * should be checked. The response to an overflow error is left to the user
- * application, however it may be necessary to clear both the capture overflow
- * flag and the capture flag upon each capture reading.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_compare_match_capt_pwc Capture Operations - Pulse Width
- *
- * Pulse Width Capture mode makes it possible to measure the pulse width and
- * period of PWM signals. This mode uses two capture channels of the counter.
- * This means that the counter module used for Pulse Width Capture can not be
- * used for any other purpose. There are two modes for pulse width capture;
- * Pulse Width Period (PWP) and Period Pulse Width (PPW). In PWP mode, capture
- * channel 0 is used for storing the pulse width and capture channel 1 stores
- * the observed period. While in PPW mode, the roles of the two capture channels
- * is reversed.
- *
- * As in the above example it is necessary to poll on interrupt flags to see
- * if a new capture has happened and check that a capture overflow error has
- * not occurred.
- *
- * \subsection asfdoc_sam0_tc_module_overview_oneshot One-shot Mode
- *
- * TC modules can be configured into a one-shot mode. When configured in this
- * manner, starting the timer will cause it to count until the next overflow
- * or underflow condition before automatically halting, waiting to be manually
- * triggered by the user application software or an event signal from the event
- * system.
- *
- * \subsubsection asfdoc_sam0_tc_module_overview_inversion Wave Generation Output Inversion
- *
- * The output of the wave generation can be inverted by hardware if desired,
- * resulting in the logically inverted value being output to the configured
- * device GPIO pin.
- *
- *
- * \section asfdoc_sam0_tc_special_considerations Special Considerations
- *
- * The number of capture compare registers in each TC module is dependent on
- * the specific SAM device being used, and in some cases the counter size.
- *
- * The maximum amount of capture compare registers available in any SAM
- * device is two when running in 32-bit mode and four in 8- and 16-bit modes.

- *
- *
- * \section asfdoc_sam0_wdt_prerequisites Prerequisites
- *
- * There are no prerequisites for this module.
- *
- *
- * \section asfdoc_sam0_wdt_module_overview Module Overview
- *
- * The Watchdog module (WDT) is designed to give an added level of safety in
- * critical systems, to ensure a system reset is triggered in the case of a
- * deadlock or other software malfunction that prevents normal device operation.
- *
- * At a basic level, the Watchdog is a system timer with a fixed period; once
- * enabled, it will continue to count ticks of its asynchronous clock until
- * it is periodically reset, or the timeout period is reached. In the event of a
- * Watchdog timeout, the module will trigger a system reset identical to a pulse
- * of the device's reset pin, resetting all peripherals to their power-on
- * default states and restarting the application software from the reset vector.
- *
- * In many systems, there is an obvious upper bound to the amount of time each
- * iteration of the main application loop can be expected to run, before a
- * malfunction can be assumed (either due to a deadlock waiting on hardware or
- * software, or due to other means). When the Watchdog is configured with a
- * timeout period equal to this upper bound, a malfunction in the system will
- * force a full system reset to allow for a graceful recovery.
- *
- * \subsection asfdoc_sam0_wdt_module_locked_mode Locked Mode
- * The Watchdog configuration can be set in the device fuses and locked in
- * hardware, so that no software changes can be made to the Watchdog
- * configuration. Additionally, the Watchdog can be locked on in software if it
- * is not already locked, so that the module configuration cannot be modified
- * until a power on reset of the device.
- *
- * The locked configuration can be used to ensure that faulty software does not
- * cause the Watchdog configuration to be changed, preserving the level of
- * safety given by the module.
- *
- * \subsection asfdoc_sam0_wdt_module_window_mode Window Mode
- * Just as there is a reasonable upper bound to the time the main program loop
- * should take for each iteration, there is also in many applications a lower
- * bound, i.e. a \a minimum time for which each loop iteration should run for
- * under normal circumstances. To guard against a system failure resetting the
- * Watchdog in a tight loop (or a failure in the system application causing the
- * main loop to run faster than expected) a "Window" mode can be enabled to
- * disallow resetting of the Watchdog counter before a certain period of time.
- * If the Watchdog is not reset \a after the window opens but not \a before the
- * Watchdog expires, the system will reset.
- *
- * \subsection asfdoc_sam0_wdt_module_early_warning Early Warning
- * In some cases it is desirable to receive an early warning that the Watchdog is
- * about to expire, so that some system action (such as saving any system
- * configuration data for failure analysis purposes) can be performed before the
- * system reset occurs. The Early Warning feature of the Watchdog module allows
- * such a notification to be requested; after the configured early warning time
- * (but before the expiry of the Watchdog counter) the Early Warning flag will
- * become set, so that the user application can take an appropriate action.
- *
- * \note It is important to note that the purpose of the Early Warning feature
- *       is \a not to allow the user application to reset the Watchdog; doing
- *       so will defeat the safety the module gives to the user application.
- *       Instead, this feature should be used purely to perform any tasks that
- *       need to be undertaken before the system reset occurs.
- *
- * \subsection asfdoc_sam0_wdt_module_overview_physical Physical Connection
- *
- * \ref asfdoc_sam0_wdt_module_int_connections "The figure below" shows how
- * this module is interconnected within the device.
- *
- * \anchor asfdoc_sam0_wdt_module_int_connections

- *   rankdir=LR;

- *     node [label="<f0> WDT | <f1> Watchdog Counter" shape=record] wdt_module;
- *     node [label="System Reset Logic" shape=ellipse style=filled fillcolor=lightgray] sys_reset;
- *   }
- *
- *   wdt_clock     -> wdt_module:f1;
- *   wdt_module:f1 -> sys_reset;
- * }
- * \enddot
- *
- * \note Watchdog Counter of SAM L21/L22 is \a not provided by GCLK, but it uses an
- *       internal 1KHz OSCULP32K output clock.
- *
- * \section asfdoc_sam0_wdt_special_considerations Special Considerations
- *
- * On some devices the Watchdog configuration can be fused to be always on in
- * a particular configuration; if this mode is enabled the Watchdog is not
- * software configurable and can have its count reset and early warning state
- * checked/cleared only.

-    // Watchdog timer on SAMD is a slightly different animal than on AVR.
-    // On AVR, the WTD timeout is configured in one register and then an
-    // interrupt can optionally be enabled to handle the timeout in code
-    // (as in waking from sleep) vs resetting the chip.  Easy.
-    // On SAMD, when the WDT fires, that's it, the chip's getting reset.
-    // Instead, it has an "early warning interrupt" with a different set
-    // interval prior to the reset.  For equivalent behavior to the AVR
-    // library, this requires a slightly different configuration depending
-    // whether we're coming from the sleep() function (which needs the
-    // interrupt), or just enable() (no interrupt, we want the chip reset
-    // unless the WDT is cleared first).  In the sleep case, 'windowed'
-    // mode is used in order to allow access to the longest available
-    // sleep interval (about 16 sec); the WDT 'period' (when a reset
-    // occurs) follows this and is always just set to the max, since the
-    // interrupt will trigger first.  In the enable case, windowed mode
-    // is not used, the WDT period is set and that's that.
-    // The 'isForSleep' argument determines which behavior is used;
-    // this isn't present in the AVR code, just here.  It defaults to
-    // 'false' so existing Arduino code works as normal, while the sleep()
-    // function (later in this file) explicitly passes 'true' to get the

-# ArduinoHttpClient
-
-ArduinoHttpClient is a library to make it easier to interact with web servers from Arduino.
-
-Derived from [Adrian McEwen's HttpClient library](https://github.com/amcewen/HttpClient)
-
-## Dependencies
-
-- Requires a networking hardware and a library that provides transport specific `Client` instance, such as:
-  - [WiFi101](https://github.com/arduino-libraries/WiFi101)
-  - [Ethernet](https://github.com/arduino-libraries/Ethernet)
-  - [WiFi](https://github.com/arduino-libraries/WiFi)
-  - [GSM](https://github.com/arduino-libraries/GSM)
-
-## Usage
-
-In normal usage, handles the outgoing request and Host header.  The returned status code is parsed for you, as is the Content-Length header (if present).
-
-Because it expects an object of type Client, you can use it with any of the networking classes that derive from that.  Which means it will work with WiFiClient, EthernetClient and GSMClient.
-
-See the examples for more detail on how the library is used.

-/* HueBlink example for ArduinoHttpClient library
-
-   Uses ArduinoHttpClient library to control Philips Hue
-   For more on Hue developer API see http://developer.meethue.com
-
-  To control a light, the Hue expects a HTTP PUT request to:
-
-  http://hue.hub.address/api/hueUserName/lights/lightNumber/state
-
-  The body of the PUT request looks like this:
-  {"on": true} or {"on":false}
-
-  This example  shows how to concatenate Strings to assemble the
-  PUT request and the body of the request.

-Thank you for opening an issue on an Adafruit Arduino library repository.  To
-improve the speed of resolution please review the following guidelines and
-common troubleshooting steps below before creating the issue:
-
-- **Do not use GitHub issues for troubleshooting projects and issues.**  Instead use
-  the forums at http://forums.adafruit.com to ask questions and troubleshoot why
-  something isn't working as expected.  In many cases the problem is a common issue
-  that you will more quickly receive help from the forum community.  GitHub issues
-  are meant for known defects in the code.  If you don't know if there is a defect
-  in the code then start with troubleshooting on the forum first.
-
-- **If following a tutorial or guide be sure you didn't miss a step.** Carefully
-  check all of the steps and commands to run have been followed.  Consult the
-  forum if you're unsure or have questions about steps in a guide/tutorial.
-
-- **For Arduino projects check these very common issues to ensure they don't apply**:
-
-  - For uploading sketches or communicating with the board make sure you're using
-    a **USB data cable** and **not** a **USB charge-only cable**.  It is sometimes
-    very hard to tell the difference between a data and charge cable!  Try using the
-    cable with other devices or swapping to another cable to confirm it is not
-    the problem.
-
-  - **Be sure you are supplying adequate power to the board.**  Check the specs of
-    your board and plug in an external power supply.  In many cases just
-    plugging a board into your computer is not enough to power it and other
-    peripherals.
-
-  - **Double check all soldering joints and connections.**  Flakey connections
-    cause many mysterious problems.  See the [guide to excellent soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for examples of good solder joints.
-
-  - **Ensure you are using an official Arduino or Adafruit board.** We can't
-    guarantee a clone board will have the same functionality and work as expected
-    with this code and don't support them.
-
-If you're sure this issue is a defect in the code and checked the steps above
-please fill in the following fields to provide enough troubleshooting information.
-You may delete the guideline and text above to just leave the following details:
-
-- Arduino board:  **INSERT ARDUINO BOARD NAME/TYPE HERE**
-
-- Arduino IDE version (found in Arduino -> About Arduino menu):  **INSERT ARDUINO
-  VERSION HERE**
-
-- List the steps to reproduce the problem below (if possible attach a sketch or
-  copy the sketch code in too): **LIST REPRO STEPS BELOW**

-Thank you for creating a pull request to contribute to Adafruit's GitHub code!
-Before you open the request please review the following guidelines and tips to
-help it be more easily integrated:
-
-- **Describe the scope of your change--i.e. what the change does and what parts
-  of the code were modified.**  This will help us understand any risks of integrating
-  the code.
-
-- **Describe any known limitations with your change.**  For example if the change
-  doesn't apply to a supported platform of the library please mention it.
-
-- **Please run any tests or examples that can exercise your modified code.**  We
-  strive to not break users of the code and running tests/examples helps with this
-  process.
-
-Thank you again for contributing!  We will try to test and integrate the change
-as soon as we can, but be aware we have many GitHub repositories to manage and
-can't immediately respond to every request.  There is no need to bump or check in
-on a pull request (it will clutter the discussion of the request).
-
-Also don't be worried if the request is closed or not integrated--sometimes the
-priorities of Adafruit's GitHub code (education, ease of use) might not match the
-priorities of the pull request.  Don't fret, the open source community thrives on
-forks and GitHub makes it easy to keep your changes in a forked repo.
-
-After reviewing the guidelines above you can delete this text from the pull request.

-
-  This library provides four key benefits:
-
-     Including `SD.h` automatically creates a global
-     `SD` object which can be interacted with in a similar
-     manner to other standard global objects like `Serial` and `Ethernet`.
-
-     Boilerplate initialisation code is contained in one method named
-     `begin` and no further objects need to be created in order to access
-     the SD card.
-
-     Calls to `open` can supply a full path name including parent
-     directories which simplifies interacting with files in subdirectories.
-
-     Utility methods are provided to determine whether a file exists
-     and to create a directory hierarchy.
-
-
-  Note however that not all functionality provided by the underlying
-  sdfatlib library is exposed.
-
-*/
-
-/*
-
-  Implementation Notes
-
-  In order to handle multi-directory path traversal, functionality that
-  requires this ability is implemented as callback functions.
-
-  Individual methods call the `walkPath` function which performs the actual
-  directory traversal (swapping between two different directory/file handles
-  along the way) and at each level calls the supplied callback function.
-
-  Some types of functionality will take an action at each level (e.g. exists
-  or make directory) which others will only take an action at the bottom
-  level (e.g. open).
-

-namespace SDLib {
-
-  // Used by `getNextPathComponent`
-#define MAX_COMPONENT_LEN 12 // What is max length?
-#define PATH_COMPONENT_BUFFER_LEN MAX_COMPONENT_LEN+1

-
-        e.g. after repeated calls '/foo/bar/baz' will be split
-             into 'foo', 'bar', 'baz'.
-
-      This is similar to `strtok()` but copies the component into the
-      supplied buffer rather than modifying the original string.
-
-
-      `buffer` needs to be PATH_COMPONENT_BUFFER_LEN in size.
-
-      `p_offset` needs to point to an integer of the offset at
-      which the previous path component finished.
-

-  \mainpage Arduino SdFat Library

-
-  \section Intro Introduction
-  The Arduino SdFat Library is a minimal implementation of FAT16 and FAT32
-  file systems on SD flash memory cards.  Standard SD and high capacity
-  SDHC cards are supported.
-
-  The SdFat only supports short 8.3 names.
-
-  The main classes in SdFat are Sd2Card, SdVolume, and SdFile.
-
-  The Sd2Card class supports access to standard SD cards and SDHC cards.  Most
-  applications will only need to call the Sd2Card::init() member function.
-
-  The SdVolume class supports FAT16 and FAT32 partitions.  Most applications
-  will only need to call the SdVolume::init() member function.
-
-  The SdFile class provides file access functions such as open(), read(),
-  remove(), write(), close() and sync(). This class supports access to the root
-  directory and subdirectories.
-
-  A number of example are provided in the SdFat/examples folder.  These were
-  developed to test SdFat and illustrate its use.
-
-  SdFat was developed for high speed data recording.  SdFat was used to implement
-  an audio record/play class, WaveRP, for the Adafruit Wave Shield.  This
-  application uses special Sd2Card calls to write to contiguous files in raw mode.
-  These functions reduce write latency so that audio can be recorded with the
-  small amount of RAM in the Arduino.
-
-  \section SDcard SD\SDHC Cards
-
-  Arduinos access SD cards using the cards SPI protocol.  PCs, Macs, and
-  most consumer devices use the 4-bit parallel SD protocol.  A card that
-  functions well on A PC or Mac may not work well on the Arduino.
-
-  Most cards have good SPI read performance but cards vary widely in SPI
-  write performance.  Write performance is limited by how efficiently the
-  card manages internal erase/remapping operations.  The Arduino cannot
-  optimize writes to reduce erase operations because of its limit RAM.
-
-  SanDisk cards generally have good write performance.  They seem to have
-  more internal RAM buffering than other cards and therefore can limit
-  the number of flash erase operations that the Arduino forces due to its
-  limited RAM.
-
-  \section Hardware Hardware Configuration
-
-  SdFat was developed using an
-  <A HREF = "http://www.adafruit.com/"> Adafruit Industries</A>
-  <A HREF = "http://www.ladyada.net/make/waveshield/"> Wave Shield</A>.
-
-  The hardware interface to the SD card should not use a resistor based level
-  shifter.  SdFat sets the SPI bus frequency to 8 MHz which results in signal
-  rise times that are too slow for the edge detectors in many newer SD card
-  controllers when resistor voltage dividers are used.
-
-  The 5 to 3.3 V level shifter for 5 V Arduinos should be IC based like the
-  74HC4050N based circuit shown in the file SdLevel.png.  The Adafruit Wave Shield
-  uses a 74AHC125N.  Gravitech sells SD and MicroSD Card Adapters based on the
-  74LCX245.
-
-  If you are using a resistor based level shifter and are having problems try
-  setting the SPI bus frequency to 4 MHz.  This can be done by using
-  card.init(SPI_HALF_SPEED) to initialize the SD card.
-
-  \section comment Bugs and Comments
-
-  If you wish to report bugs or have comments, send email to fat16lib@sbcglobal.net.
-
-  \section SdFatClass SdFat Usage
-
-  SdFat uses a slightly restricted form of short names.
-  Only printable ASCII characters are supported. No characters with code point
-  values greater than 127 are allowed.  Space is not allowed even though space
-  was allowed in the API of early versions of DOS.
-
-  Short names are limited to 8 characters followed by an optional period (.)
-  and extension of up to 3 characters.  The characters may be any combination
-  of letters and digits.  The following special characters are also allowed:
-
-  $ % ' - _ @ ~ ` ! ( ) { } ^ # &
-
-  Short names are always converted to upper case and their original case
-  value is lost.
-
-  \note
-  The Arduino Print class uses character
-  at a time writes so it was necessary to use a \link SdFile::sync() sync() \endlink
-  function to control when data is written to the SD card.
-
-  \par
-  An application which writes to a file using \link Print::print() print()\endlink,
-  \link Print::println() println() \endlink
-  or \link SdFile::write write() \endlink must call \link SdFile::sync() sync() \endlink
-  at the appropriate time to force data and directory information to be written
-  to the SD Card.  Data and directory information are also written to the SD card
-  when \link SdFile::close() close() \endlink is called.
-
-  \par
-  Applications must use care calling \link SdFile::sync() sync() \endlink
-  since 2048 bytes of I/O is required to update file and
-  directory information.  This includes writing the current data block, reading
-  the block that contains the directory entry for update, writing the directory
-  block back and reading back the current data block.
-
-  It is possible to open a file with two or more instances of SdFile.  A file may
-  be corrupted if data is written to the file by more than one instance of SdFile.
-
-  \section HowTo How to format SD Cards as FAT Volumes
-
-  You should use a freshly formatted SD card for best performance.  FAT
-  file systems become slower if many files have been created and deleted.
-  This is because the directory entry for a deleted file is marked as deleted,
-  but is not deleted.  When a new file is created, these entries must be scanned
-  before creating the file, a flaw in the FAT design.  Also files can become
-  fragmented which causes reads and writes to be slower.
-
-  Microsoft operating systems support removable media formatted with a
-  Master Boot Record, MBR, or formatted as a super floppy with a FAT Boot Sector
-  in block zero.
-
-  Microsoft operating systems expect MBR formatted removable media
-  to have only one partition. The first partition should be used.
-
-  Microsoft operating systems do not support partitioning SD flash cards.
-  If you erase an SD card with a program like KillDisk, Most versions of
-  Windows will format the card as a super floppy.
-
-  The best way to restore an SD card's format is to use SDFormatter
-  which can be downloaded from:
-
-  http://www.sdcard.org/consumers/formatter/
-
-  SDFormatter aligns flash erase boundaries with file
-  system structures which reduces write latency and file system overhead.
-
-  SDFormatter does not have an option for FAT type so it may format
-  small cards as FAT12.
-
-  After the MBR is restored by SDFormatter you may need to reformat small
-  cards that have been formatted FAT12 to force the volume type to be FAT16.
-
-  If you reformat the SD card with an OS utility, choose a cluster size that
-  will result in:
-
-  4084 < CountOfClusters && CountOfClusters < 65525
-
-  The volume will then be FAT16.
-
-  If you are formatting an SD card on OS X or Linux, be sure to use the first
-  partition. Format this partition with a cluster count in above range.

-  WiFi Web Server LED Blink
-
-  A simple web server that lets you blink an LED via the web.
-  This sketch will create a new access point (with no password).
-  It will then launch a new server and print out the IP address
-  to the Serial monitor. From there, you can open that address in a web browser
-  to turn on and off the LED on pin 13.
-
-  If the IP address of your shield is yourAddress:
-    http://yourAddress/H turns the LED on
-    http://yourAddress/L turns it off
-
-  created 25 Nov 2012
-  by Tom Igoe
-  adapted to WiFi AP by Adafruit

- MDNS WiFi Web Server
-
- A simple web server that shows the value of the analog input pins,
- and exposes itself on the MDNS name 'wifi101.local'.
-
- On Linux (like Ubuntu 15.04) or OSX you can access the web page
- on the device in a browser at 'http://wifi101.local/'.
-
- On Windows you'll first need to install the Bonjour Printer Services
- from:
-   https://support.apple.com/kb/dl999?locale=en_US
- Then you can access the device in a browser at 'http://wifi101.local/'.
-
- This example is written for a network using WPA encryption. For
- WEP or WPA, change the WiFi.begin() call accordingly.
-
- Circuit:
- * WiFi shield attached
- * Analog inputs attached to pins A0 through A5 (optional)

-				will be set to infinite (the recv function waits forever).
-
-@pre
-	- The socket function must be called to allocate a UDP socket before passing the socket ID to the recvfrom function.
- 	- The socket corresponding to the socket ID must be successfully bound to a local port through the call to a @ref bind function.
-	
-@see
-	socket
-	bind
-	close
-
-@return		
-	The function returns ZERO for successful operations and a negative value otherwise.
-	The possible error values are:
-	- [SOCK_ERR_NO_ERROR](@ref SOCK_ERR_NO_ERROR)	
-		Indicating that the operation was successful.
-		
-	- [SOCK_ERR_INVALID_ARG](@ref SOCK_ERR_INVALID_ARG)
-		Indicating passing invalid arguments such as negative socket ID or NULL Receive buffer.
-
-	- [SOCK_ERR_BUFFER_FULL](@ref SOCK_ERR_BUFFER_FULL)
-		Indicate socket receive failure.
-\section Example
-   The example demonstrates a code snippet for the calling of the recvfrom function in the socket callback upon notification of a successful bind event, and the parsing of the 
-   received data when the  SOCKET_MSG_RECVFROM event is received.
-@code
-	switch(u8Msg)
-	{	
-
-	case SOCKET_MSG_BIND:
-		{
-			tstrSocketBindMsg	*pstrBind = (tstrSocketBindMsg*)pvMsg;
-
-			if(pstrBind != NULL)
-			{
-				if(pstrBind->status == 0)
-				{
-					recvfrom(sock, gau8SocketTestBuffer, TEST_BUFFER_SIZE, 0);
-				}
-				else
-				{
-					M2M_ERR("bind\n");
-				}
-			}
-		}
-		break;
-
-
-	case SOCKET_MSG_RECVFROM:
-		{
-			tstrSocketRecvMsg	*pstrRx = (tstrSocketRecvMsg*)pvMsg;
-			
-			if(pstrRx->s16BufferSize > 0)
-			{
-				//get the remote host address and port number
-				uint16 u16port = pstrRx->strRemoteAddr.sin_port;
-				uint32 strRemoteHostAddr = pstrRx->strRemoteAddr.sin_addr.s_addr;
-
-				printf("Recieved frame with size = %d.\tHost address=%x, Port number = %d\n\n",pstrRx->s16BufferSize,strRemoteHostAddr, u16port);
