I am trying to build a custom Zynthian with a Raspberry 3B V1.2.
I have a Kuman 3.5 TFT resistive touchscreen that woks ok with the generic HDMI configuration.
I’d like to make it work with its drivers in order to use the resistive touchscreen and keep the HDMI plug available.
I also tried to compile the driver according to these instructions but then i get a messed up and blurred image.
Did anyone had success with this screen and would kindly share some tips on how to make it work?
Thank you very much!
