Video/ GUI on LCD SPI screen 240x240 + GC9A01

Fri Sep 17, 2021 2:25 pm

Hey :)
I want to show rpi GUI on this round LCD over SPI.
https://www.waveshare.com/wiki/1.28inch_LCD_Module

Like they do in this repo:
https://github.com/goodtft/LCD-show
Example: https://www.youtube.com/watch?v=KNWXmJBNWCo

But this screen have a different controller/ driver - GC9A01.

I managed to show some pictures with the example code. But that's it.

The only way I found is with fbcp (mirroring the HDMI buffer to the SPI or something... It's not even in English):

1. Are there library for that controller?
2. Maybe library for different controller can also work with this one?
3. Should I go with the fbcp option?

It's all very confusing and I would love your help!
Thanks
