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

TODO

  • Debouncing in the kscan driver itself? Only some GPIO drivers in Zephyr support it "natively"
  • Better DTS overlay setup for keymaps. Current use of SHIELDs works, but perhaps would be better with something more integrated.
  • 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.
  • BLE SC by typing in the # prompted on the host.
    • Store the connection being authenticated.
    • Hook into endpoint flow to detect keypresses and store/send them to the connection once 6 are typed.
  • 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.

Long Term

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