Calliope Board Support Crate

This project should become a board support crate for the Calliope mini single board computer.

At current, it is very beta!

As of now, the code is only tested with a Calliope mini 1.0 due to hardware availability.

The Calliope mini 1.0 is very similar to the Microbit v1.3, uses the same Nordic nRF51822 processor and has some similarities in the schematic. Some code, especially for the 25 LEDs works on both boards.

Therefore, we will take over some code from the microbit board support crate and examples from the rust discovery book.

Warning: I'm still learning embedded Rust and HAL design, so none of this looks good yet!

Here is the state of the supported hardware:

Repositories
