I took a WaveShare RP2040-Touch-LCD-1.28and made a program to use it as a touchscreen. This is still very much in the beta phase but the proof of concept works. Here’s my GitHub repo for it.

I’m planning on integrating it into my next split near the thumb cluster.

    Oh neat! QMK seems to be the most appropriate for trackpads. I was thinking of something that could be wireless which afaik QMK doesn’t support. And ZMK’s support for pointer devices is not great just yet.

      I hear you. The two issues are this model has no wireless as it’s rp2040. Also a touchscreen is pretty power hungry for a wireless device like a keyboard that is supposed to be charged infrequently.

        Yeah, both valid points. I was asking about the firmware supporting an esp32 specifically for the wireless capabilities. And on terms of battery life, I went overboard and installed 3000mAh batteries in my keyboard that I can use to power the display 😂
