Adding Support for New Hardware
RMK can run on any hardware platform with Embassy support. To enable specific communication:
- USB Support: Requires implementation of embassy-usb-driver traits.
- BLE Support: Requires implementation of bt-hci traits.
Once your hardware has the corresponding trait implementations, RMK support will be available out of the box.
