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
