Hi @Ernst ,
As promised a VSCode project is attached.
I would suggest creating a project using ESP-IDF: Show Example Projects and using the rgb_panel example in peripherals->lcd then overwrite the project directory with the contents of the attached zip file and then build and flash the project. Hopefully it should work with 8048S043 board.
rgb_panel.zip (45.1 KB)
I hope it works for you.
Kind Regards,
Pete
