RMK

Keyboard firmware for cortex-m, with layer/dynamic keymap/vial support, written in Rust.

Checklist after generating the firmware project

• Update memory.x for your microcontroller(if needed)

• Update your keyboard.toml

• Create your vial.json by your layout: https://get.vial.today/docs/porting-to-via.html, replace the default one

• (Optional) Check the chip name of probe-rs is right, if you don't use cargo run, you can skip this step

• Update the family ID of your microcontroller in Makefile.toml, if you want to generate .uf2 firmware. The available family ID can be found in scripts/uf2conv.py

For BLE only

To use NRF BLE, you should have nrf s140 softdevice 7.3.0 flashed to nrf52840 first.

The following are the detailed steps:

1. Erase the flash:

   probe-rs erase --chip nrf52840_xxAA

2. Flash softdevice firmware to flash:

   probe-rs download --verify --format hex --chip nRF52840_xxAA s140_nrf52_7.3.0_softdevice.hex

3. Compile, flash and run the example

   cargo run --release
