Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I have one of these boards and would like to know if it will be possible to use it on the Picomite
Waveshare 1.14" LCD 240X135
Website says it uses an ST7789 Driver
https://www.waveshare.com/pico-lcd-1.14.htm

Has anyone managed to use one of these with the Picomite? If so could you share your OPTION SYSTEM SPI and OPTION LCD PANEL settings.
It looks like there are some Pin conflicts, so is there a way to get around this?

The  Picomite Pin out diagram in the manual (pg. 9) shows Pins 31, 32 and 34 as being " SP2" pins, is this an error and they should be SPI2?









Cheers

Thanks, I'll  try that tomorrow. I think I did try GP28 in one of the combinations, but I will confirm.

Good catch - yes, I think so.
