ESP32-C3 RTIC template

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

Prerequisites

Espressif toolchain

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

Running the crate

Uncomment the

runner = "espflash flash --monitor"

line in .cargo/config.toml

and comment out (or remove)

runner = "./runner.sh"

Now, running

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

in the root of this crate should do the trick.

Expected behavior

The example sw_and_hw

• 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

The example monotonic

• Prints init
• Spawns the foo, bar, baz tasks (because of hardware interrupt latency dispatch, the order here may vary).
• Each task prints hello from $TASK on entry
• The tasks wait for 1, 2, 3 seconds respectively
• Once the wait period is over, each task exits printing bye from $TASK (now in the proper order).
