# Zephyr Mechanical Keyboard (ZMK) Firmware

This project is a complete work in progress, with absolutely nothing functioning yet. The goal is to explore a new MK firmware
with a less restritive license and better BLE support, built on top of the [Zephyr Project](https://www.zephyrproject.org/)

## TODO

- Document boards/shields/keymaps usage.
- Move most Kconfig setings to the board/keymap defconfigs and out of the toplevel `prj.conf` file.
- Merge the Kscan GPIO driver upstream, or integrate it locally, to avoid use of Zephyr branch.
- Display support, including displaying BLE SC auth numbers for "numeric comparison" mode if we have the screen.
- Fix BT settings to work w/ Zephyr. Do we really need them?
- Tests?

# Missing Features

- Consumer Key Support (play/pause, etc)
- Mod Tap
- One Shot
- Shell over BLE?
- Split support
  - custom kscan driver? that recieves events from other side over BLE notifications?
  - Need to figure out how to do "custom" GATT services. Custom UUID?
  - Do we need to send any state updates over from primary to secondary side?
- Encoders
- Battery reporting.
- Low power mode, with wakeup from interrupt?

## Long Term

- Tool to convert keymap `info.json` files into a DTS keymap file?
- Firmware build service?
