Pure Rust firmware for my Raspberry Pi Pico-powered macropad, built using Pimoroni's RGB keypad base and display pack.
You'll need the Rust toolchain for thumbv6m-none-eabi and the elf2uf2-rs tool:
rustup target add thumbv6m-none-eabi
cargo install elf2uf2-rs --locked
After that, the standard cargo commands should work. If a Pico is connected, cargo run will automatically flash the executable.
