Design Principles

1. Layered Architecture: Clear separation of concerns
2. Single Responsibility: Each module has one job
3. HAL Abstraction: Hardware access only through HAL layer
4. No Re-initialization: Peripherals initialized once in main()
5. Event-Driven: Scheduler triggers periodic operations
6. Non-Blocking: All operations use timeouts or polling

Module Overview

Hardware Abstraction Layer (HAL)

The HAL provides a clean interface to PIC16F886 peripherals:

Module	Purpose	Key Functions
hal_adc	Analog-to-Digital conversion	adc_init(), adc_read(ch)
hal_uart	Serial communication	uart_init(baud), uart_send_byte()
hal_i2c	I2C bus communication	hal_i2c_init(), hal_i2c_read/write()
hal_spi	SPI communication	spi_init(), spi_send_byte()
hal_pwm	PWM signal generation	pwm_init(), pwm_set_percent()
hal_eeprom	Non-volatile storage	eeprom_read/write(addr, val)

Design Principle: Upper layers never access registers directly - all hardware interaction goes through HAL.

See hal/README.md for detailed API reference and configuration details.

Sensor Layer

Sensor	Interface	Range	Update Rate	Special Notes
LM35	ADC AN0	0-255°C	5s	10mV/°C, direct read
HIH4000	ADC AN1	0-100% RH	5s	Requires temperature compensation
Microphone	ADC AN2	3 categories	1s	Maximum of 100 samples
VEML7700	I2C 0x10	0-65535 lux	5s	16-bit light sensor
iAQ-Core	I2C 0x5A	0-65535 ppm	5s	5-minute warmup period

See sensor/README.md for calibration procedures, wiring diagrams, and troubleshooting.

Actuator Layer

Actuator	Interface	Control Range	Notes
SK9822 LED	SPI (RC0/RC1)	RGB: 0-255, Brightness: 0-31	Supports multiple LEDs (N_LEDS)
Fan	PWM (RC2)	0-100% speed	20 kHz frequency, 10-bit resolution

See actuador/README.md for control algorithms and safety considerations.

Protocol Layer

UART Protocol: Custom binary protocol with CRC-8 error detection

• Frame Format: [HEADER][LEN][CMD][DATA...][CRC_L][CRC_H]
• Baudrate: 9600 bps (8N1)
• Commands: 7 bidirectional commands (see protocol documentation)
• Error Detection: CRC-8-CCITT (polynomial 0x07)

Scheduler: Time-based event system driven by Timer0 (10ms) and Timer1 (~105ms)

See protocol/README.md for complete protocol specification and examples.

Communication Protocol

Data Flow: PIC → Host (SMA-COMP)

Every 1 second:
    └─→ [AA 04 00 {cat} 00 00]          CMD_NOISE

Timing & Scheduling

Timer Configuration

Timer0 (10ms tick)

Fosc/4 = 20MHz / 4 = 5 MHz
Period = 0.2 µs
Prescaler 1:256 → tick every 51.2 µs
10ms / 51.2µs = 195.3 ticks
Preload = 256 - 195 = 61

OPTION_REG = 0b10000111  // nRBPU=1 (PORTB pull-ups OFF), PSA=0, PS=111 (1:256), T0CS=0 (Fosc/4)
TMR0 += 61               // Compensated reload

Timer1 (~105ms tick)

Fosc/4 = 5 MHz
Prescaler 1:8 → tick every 1.6 µs
Overflow = 65536 × 1.6µs = 104.8576 ms

T1CON = 0b00110001      // TMR1ON=1, TMR1CS=0 (Fosc/4), T1CKPS=11 (1:8), TMR1GE=0 (always count)

ISR (Interrupt Service Routine)

void __interrupt() isr(void) {
    // Every 10ms
    if(TMR0IF && TMR0IE) {
        TMR0IF = 0;
        TMR0 += 61;  // Compensated reload (avoids drift)
        
        scheduler_tick_10ms();
        
        // Sample noise and keep maximum over 1s window
        noise_cat_t cat = noise_read_category();
        if(cat > noise_max_cat) noise_max_cat = cat;
    }
    
    // Every ~105ms
    if(TMR1IF && TMR1IE) {
        TMR1IF = 0;
        scheduler_tick_100ms();
    }
}

IMPORTANT: TMR0 += 61 compensates for ISR latency, preventing cumulative drift.

Testing

The project includes 9 standalone test programs in the test/ folder:

Test	Purpose	Hardware Required
test_fan	PWM fan ramp (0→80%→0%)	Fan on RC2
test_led	LED color cycling	SK9822 on RC0/RC1

    if(scheduler_noise_ready()) {
        protocol_send(CMD_NOISE, {noise_max_cat}, 1);
        noise_max_cat = NOISE_LOW;  // Reset window

        co2_update_warmup();         // Increment warmup counter
        
        temp = temp_read_degC();
        hum = hum_read_percent();

        protocol_send(CMD_TEMP, ...);
        protocol_send(CMD_HUM, ...);
        protocol_send(CMD_LUX, ...);
        protocol_send(CMD_CO2, ...);
    }
    
    // Event 3: Command reception (asynchronous)
    if(protocol_receive(&cmd, buf, &len)) {
        switch(cmd) {
            case CMD_FAN:
                current_fan_speed = buf[0];
                fan_set_speed(current_fan_speed);
                break;
            case CMD_LEDS:
                current_led_r = buf[0];
                current_led_g = buf[1];
                current_led_b = buf[2];
                current_led_brightness = buf[3];
                led_set_color(...);
                break;
        }
        
        // Activity indicator: flash green LED
        led_set_color(0, 255, 0, 10);
        __delay_ms(50);
        led_set_color(current_led_r, current_led_g, current_led_b, current_led_brightness);
    }
}

Non-blocking: All operations use polling or timeouts (no infinite loops).

EEPROM Persistence

Memory Map

Address	Content	Range	Description
0x00	LED Brightness	0-31	Masked with 0x1F
0x01	LED Red	0-255	RGB component
0x02	LED Green	0-255	RGB component
0x03	LED Blue	0-255	RGB component
0x04	Fan Speed	0-100	Percentage

Save Strategy

When: Every 5 seconds (called from scheduler_env_ready())

Why:

• Protects against power loss
• Reduces EEPROM wear (~1M cycle limit)
• Max 5s data loss window

Function:

static void save_actuators_state(void) {
    eeprom_write(0x00, current_led_brightness);
    eeprom_write(0x01, current_led_r);
    eeprom_write(0x02, current_led_g);
    eeprom_write(0x03, current_led_b);
    eeprom_write(0x04, current_fan_speed);
}

Restore on Boot

1. Read all 5 addresses
2. Check if empty (0xFF indicates first boot)
3. If empty: use defaults (white LED, fan off)
4. If valid: apply saved configuration

No UART output	Crystal not oscillating	Verify crystal, capacitors, FOSC=HS
UART sends garbage	Baudrate mismatch	Verify SPBRG=129, _XTAL_FREQ=20MHz
I2C sensors don't respond	Missing pull-ups	Add 4.7kΩ on RC3 (SCL) and RC4 (SDA)
CO₂ always reads 0xFFFF	Sensor in warmup	Wait 5 minutes after power-on
Fan doesn't run	Pin not configured	Verify TRISC2=0, CCP1CON=0x0C
LEDs don't light	Wrong SPI pins	Verify RC0 (CLK), RC1 (SDO) connections
Random resets	Brown-out	Check 5V supply stable, BOREN=ON
EEPROM data lost	Not saving	Verify save_actuators_state() called every 5s

Diagnostic Features

Startup Test Frames (100ms after boot):

AA 04 00 00 00 00    → CMD_NOISE = 0
AA 04 06 19 00 00    → CMD_TEMP = 25°C

Purpose: Verify UART TX works immediately after boot.

LED Activity Indicator:

• Green flash (50ms) when valid command received
• Indicates: UART RX works + protocol parsing OK

Debug Terminal Test

1. Connect terminal @ 9600 8N1 to RC6 (TX)
2. Power on PIC
3. Should see 2 frames within 200ms
4. Every 1s: CMD_NOISE frame
5. Every 5s: 4 sensor frames (TEMP, HUM, LUX, CO2)

If no output → hardware issue (crystal, power, connections).

Performance Metrics

Metric	Value	Notes
CPU Usage	~15%	ISR: 2%, Main loop: 13%
RAM Usage	~200 bytes	54% of 368 bytes
Flash Usage	~5-8 KB	60-100% of 8KB (depends on optimization)
EEPROM Writes	5 writes/5s	~100k cycles = 139 hours continuous
ISR Frequency	110 Hz	Timer0: 100 Hz, Timer1: 10 Hz
Worst ISR Latency	<50 µs	Including noise sampling

Safety Features

1. Brown-Out Reset: Detects low voltage, resets safely
2. UART Timeout: Prevents infinite blocking (100ms)
3. EEPROM Wear Leveling: Saves every 5s (not every command)
4. Watchdog: Disabled (system is deterministic)
5. Interrupt Priority: Timers only (no nesting issues)
