Safe Rust wrappers for the services in the ESP IDF SDK

Highlights

• Supports almost all ESP IDF services: timers, event loop, Wifi, Ethernet, HTTP client & server, MQTT, WS, NVS, OTA, etc.
• Implements the traits of embedded-svc
• Blocking and async mode for each service (async support where feasible)

Build Prerequisites

Follow the Prerequisites section in the esp-idf-template crate.

Examples

The examples could be built and flashed conveniently with cargo-espflash. To run e.g. wifi on an e.g. ESP32-C3: (Swap the Rust target and example name with the target corresponding for your ESP32 MCU and with the example you would like to build)

with cargo-esptool v1.7:

$ ESP_IDF_VERSION=release/v4.4 cargo espflash --target riscv32imc-esp-espidf --example wifi --monitor /dev/ttyUSB0

with cargo-esptool v2.0:

$ ESP_IDF_VERSION=release/v4.4 cargo espflash flash --target riscv32imc-esp-espidf --example wifi --monitor

Setting up a "Hello, world!" binary crate with ESP IDF

Use the esp-idf-template project. Everything would be arranged and built for you automatically - no need to manually clone the ESP IDF repository.
