pi-transceiver-firmware

This is firmware that runs on an stm32. It receives data from a connected Raspberry Pi and transmits it via an si4463 transceiver chip. For more information, see this article.

Compiling & Installing (Linux)

Environment setup

First, install Rustup: https://rustup.rs

After that is installed, restart your terminal, or open a new one. Then run these commands:

rustup target add thumbv7em-none-eabihf # add our board architecture, if needed
cargo install flip-link # needed for building
cargo install cargo-dfu # needed for flashing

Board setup

1. Connect the board to your computer via USB
2. Hold down the flash button
3. Momentarily press the reset button
4. Release the flash button

Finally, you're ready to compile and flash. This is a single command:

cargo dfu --release

This could take a few minutes, especially on an older system. If it complains about a permission issue, you may need to prepend sudo to the command. Once it completes, the board will reboot automatically. Congratulations - your firmware is now installed!
