async mode for each service (async support where feasible)esp-idf-hal and esp-idf-sys as esp_idf_svc::hal and esp_idf_svc::sys. You only need to depend on esp_idf_svc to get everything you needYou might want to also check out the ESP IDF Drivers wrappers, and the raw bindings to ESP IDF in the esp-idf-sys crate!
Please note that all esp-idf-* crates are a community effort, in that Espressif puts little to no paid developer time in these. So while ESP-IDF itself is very popular and well tested, the esp-idf-* crates:
For a HAL which is officially supported by Espressif (as in - with paid developer time), please look at esp-hal. Keep in mind that esp-hal is no_std-only, does not use ESP-IDF and requires async programming.
Follow the Prerequisites section in the esp-idf-template crate.
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-espflash:
$ MCU=esp32c3 cargo espflash flash --target riscv32imc-esp-espidf --example wifi --monitorMCU "--target" esp32c2 riscv32imc-esp-espidf esp32c3 riscv32imc-esp-espidf esp32c6 riscv32imac-esp-espidf esp32h2 riscv32imac-esp-espidf esp32p4 riscv32imafc-esp-espidf esp32 xtensa-esp32-espidf esp32s2 xtensa-esp32s2-espidf esp32s3 xtensa-esp32s3-espidf 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.
