# 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
|
|
|
|
|
|
|
|
|
|
- Debouncing in the kscan driver itself? Only some GPIO drivers in Zephyr support it "natively"
|
|
|
|
|
- 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?
|
|
|
|
|
- Update the kscan GPIO driver to use interrupts.
|
|
|
|
|
- Try disabling callbacks for the read pins temporarily when scanning, then re-enabling them.

|
|
|
- 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?
