Anyone familiar with QMK firmware for custom keyboards?

A few years ago I did a Kickstarter for a macro pad called the JC Pro Macro 2. It was programmed in the Arduino IDE, and worked really well for my purposes, but I’ve finally put some time into QMK firmware for it. Anyone familiar with this firmware system for keyboards? Here’s what I’ve got so far: https://github.com/JeremySCook/JC-Pro-Macro-2/tree/main/code/QMK (actually may be a tiny bit farther with my local copy, but that should be close).

Keys and encoder working, and can switch layers, but lighting and OLED display aren’t working correctly yet. Still, QMK looks very promising!

    Making some progress on my QMK macropad firmware. Lights change per layer, and OLED shows the keyswitch and encoder commands each one.

    Next steps are to hopefully set it up for QMK’s online configurator, and possibly implement a random mouse routine. Also would love if the lights on the keyswitches move with the encoder, but I’m not yet sure how to do that in QMK.

    More progress on my QMK macro pad setup. The bottom lights shine according to the layer that I’m using, while the top lights under each keyswitch get visibly “hotter” as i press them over and over. It took me a while to figure things out (I don’t have it all figured out) but wow, QMK is extremely powerful. There are many other animations too. Here’s my ~current code: https://github.com/JeremySCook/JC-Pro-Macro-2/tree/main/code/QMK/jcpm2

    if you could try adding MIDI support
    it could be a good synthesizer

    Oh man, you read my mind! Or reminded me of what I meant to do at least. QMK has that functionality so it should be pretty easy to add it in: https://github.com/qmk/qmk_firmware/blob/master/docs/keycodes.md#midi-midi
