Urchin RMK Ergo-L

A firmware for the Urchin Keyboard, made with RMK to use with the layout Ergo-L.

Install instructions

• Install the layout Ergo-L on your machine
• Build and flash the firmware to the keyboard
  1. cargo make uf2 --release
  2. Flash each uf2 file to its keyboard part (central is left), with drag-&-drop.

Debugging

To understand how the controller event works without a debug probe, the log_controller module can be used.

1. Add heapless to the project: cargo add heapless
2. Replace the ScreenController with the LogController:

mod log_controller;
use log_controller::LogController;

#[rmk_central]
mod keyboard_central {
    #[controller(event)]
    fn screen_controller() -> LogController {
        /*
        ...
        */

        LogController {
            sub: unwrap!(CONTROLLER_CHANNEL.subscriber()),
            display,
            log_history: [None; LOG_LINES],
        }
    }
}
