GC9A01 LCD and Pico2 or Pi4/5 Headers

Hi All,

I am trying to interface multiple GC9A01 Round LCD screens with either a Pico2 or onto headers of Pi4 or 5.

What I am wondering is on the Pico2, how many are possible on a single board. I watched the Arduino and ESP32 video and it seems the only different pin I need in the ChipSelect. If someone has done this before a wiring diagram would be sensational.

Also inyerested to know what libraries I should use with either and possible examples in python. Ive had a good look at some on GitHub.

I think I have the pinouts for Pi4 sorted, for 4 devices, just confused about the libraries and python part.

Kemen
