Hi,
I face similar issues with an older JoyIt display (TFT 3.2) touch display.
My setup is as follows: Raspberry Pi 4 with latest OS 64bit light installed. Respective drivers for the TFT installed and working (checked by using the fbi tool to show images. On hdmi0 I have a Samsung LED Screen (/dev/fb0) and the TFT is configured to be /dev/fb1.
Kodi also installed. I post my config.txt below for easier reading.
What I want to achieve is to use the Raspberry as a Mediaplayer and the additional TFT to show additional information using KodiDisplayInfo.
Currently I have installed python3 and pygame 2.1.2 and used the following python script for testing:
My first impression was that the script did not worked at all (while running kodi on the main display fb0). But exiting kodi showed that the image was just shown on the main screen instead of the TFT regardless which device I set in SDL_FBDEV.
I managed to update the pygame module t 2.5.2 with above hints but then the script did not work anymore - print(pygame.display.get_driver()) says "offscreen". So I reverted back to 2.1.2 for now.
As the fbi tool can indeed display images on both devices fb0 and fb1 I assume there must be something broken in the pygame module.
Experimenting with switching off dtparam=i2s and dtparam=spi which I found in some other thread also did not help.
Does anybody have soime hint here?
Kind regards,
Stephan
