ESP32-C3 RTIC template

This crate showcases a simple RTIC application for the ESP32-C3.

Prerequisites

Nightly Rust

The ESP32-C3 HAL requires a nightly build of Rust. Following the example of the (Espressif no_std book)[https://docs.esp-rs.org/no_std-training/02_2_software.html], we use this specific build: rustup toolchain install nightly-2023-11-14 --component rust-src --target riscv32imc-unknown-none-elf

Espressif toolchain

This crate uses the most convenient option in cargo-espflash and espflash cargo install cargo-espflash espflash

Running the crate

cargo run --example sw_and_hw --features=riscv-esp32c3-backend (--release)

should do the trick.

Expected behavior

The program

  • Prints init
  • Enters a high prio task
  • During the execution of the high prio task, the button should be non-functional
  • Pends a low prio task
  • Exits the high prio task
  • Enters the low prio task
  • During the execution of the low prio task, the button should be functional.
  • Exits the low prio task
  • Prints idle
