Rust & RIOT OS combined for ergonomic embedded development
This is an experimental project trying to provide a nice base OS for embedded development on low-end IoT devices (with some kilobytes of RAM/flash, think Cortex-M). It combines the awesome Rust embedded ecosystem with RIOT OS.
This is highly experimental. Expect heavy changes and breakage!
If you're looking for a more production ready way of writing RIOT applications in Rust, check out riot-wrappers.
This currently only supports the Nordic nrf52840dk.
- improve RIOT OS using the merits of Rust.
- provide a "rusty" development workflow (e.g., using cargo / crates.io)
- provide a nice Rust API, framework and collection of crates suitable for embedded development
- rewrite parts of RIOT in Rust to improve robustness and maintainability
This project currently allows to build a RIOT application with an embedded Rust based rt+linking. In addition, it provides a Rust rewrite of RIOT's "core" module, providing API compatible implementations of RIOT's scheduler, mutexes, thread flags, msg and mbox. riot-wrappers are integrated for developing applications using Rust, though this has not been used / tested much.
Assuming you have a Nordic nrf52840dk connected, this should get you somewhere:
1.install needed system dependencies. On Ubuntu, this should be sufficient:
apt-get install build-essential curl git python3 pkg-config \ libssl-dev llvm-dev cmake libclang-dev gcc-arm-none-eabi \ clang libnewlib-nano-arm-none-eabi unzip lld ninja-build
cargo install laze
clone this repository and cd into it
set up RIOT-rs toolchain
laze task install-toolchain laze task install-c2rust laze task clone-riot
Flash some example
Compile and flash the bottles example
laze -C examples/bottles task -b nrf52840dk flash
in another window, run a terminal program of your choice to watch the nrf52840dk's serial output
Building RIOT C applications with RIOT-rs
It is possible to build any RIOT application using RIOT-rs and its core
laze -Cexamples/riot-app task -b nrf52840dk -a riot-app -DRIOT_APP=foo/bar flash
See the riot-app docs for more information.
Please look here for more usage information.
Minimum Supported Rust Version (MSRV)
RIOT-rs makes heavy use of Rust unstable features. For the time being, it is recommended to use a current nightly.
