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.
Actually that makes perfect sense and I live the idea! All it has to do is check where your initial touch was. If I’m ce center, then trackpads off on the edges of the circle then scroll. I may even be able to use LVGL to make that even better in the future. Thanks for the tip. And for right click I am planning on a hold, and tap+hold for drag.
