A simple board to control an Si5351 clock generator board with the
|
|
|
|
|
TWI. Though, this is not limited to the Si5351 board as it is designed
|
|
|
|
|
to be universal usable.

backlight driver, a switchable rotary encoder and powered by a mini

## Firmware
|
|
|
|
|
Currently there are two different firmwares. The older one which is
|
|
|
|
|
written in C and is not finished, and the newer one which is in an
|
|
|
|
|
early but functioning state and written in Rust.
|
|
|
|
|
|
|
|
|
|
### The Rust Firmware
|
|
|
|
|
To flash the firmware, connect the ICSP pins of the board to the
|
|
|
|
|
programmer and inside the `firmware/rust/` directory run `cargo make
|
|
|
|
|
all`. This burns the fuses, writes the the default values to the
|
|
|
|
|
eeprom and flashes the firmware.
