Rust no_std, embedded_hal board support package for the Electro-Smith Daisy platform.

Supported boards

Currently this library supports following boards:

Select the board by using its respective feature.

Flashing an example

Using DFU. Connect using a sigle USB cable, click BOOT+RESET before flashing:

make flash-dfu WHAT=blinky BOARD=seed_1_1

Using probe-rs. This requires ST-Link probe, but provides additional logs and panic messages:

make flash WHAT=blinky BOARD=seed_1_1

API stability

I am still trying to figure out a good API for the project. Expect it to change. To mitigate breakage of your code on library update, use macros defined under board.rs to initialize resources whenever possible.

HAL compatibility

This library is closely tied to stm32h7xx-hal. Make sure to use compatible versions in your Cargo.toml.

  • This library aims to abstract all peripherals that are available on Daisy.
  • This library will not abstract anything that is not on Daisy, e.g. pots, SD cards, MIDI, ...
