#180 in Hardware support
microbit contains everything required to get started using Rust to create firmwares for the fabulous BBC micro:bit microcontroller board. This little board has everything and a kitchen sink built-in, even a capable debugging interface.
All you need to start programming this device is:
- A BBC micro:bit board
- A computer (macOS and Linux work perfectly, Windows tested as well)
- A bit of open source software
The micro:bit comes in different versions. There is a separate crate for each major board version. See the table below to identify which crate you need to use.
|Crate||Board version||Board image||Docs||crates.io||target|
> cargo install probe-run flip-link
The first thing to try is one of the examples in this repository. Plug in your micro:bit and run one of the commands below.
For micro:bit V1
> cargo run --release --manifest-path ./examples/display-blocking/Cargo.toml --features v1 --target thumbv6m-none-eabi
For micro:bit V2
> cargo run --release --manifest-path ./examples/display-blocking/Cargo.toml --features v2 --target thumbv7em-none-eabihf
You should see a lot of build output, the orange LED on the back of the micro:bit should flash quickly and a message should appear on the LED display.
Congratulations! You've flashed your first rust program onto your micro:bit!
A guide to embedded development with Rust on the microbit using this crate can be found in the MicroRust book.
