I recently bought some of these screens (ESP32-2432s022c)
I tried configuring it based on your github but I only am able to get some distorted images on the display. ( snow pattern )
It uses ST7789 driver and the same touch driver as your board. The difference is that the tft display uses an 8 bit parallel bus.
It also needs to use lovyanGFX since it uses pin's above 31
I have some sample code that runs perfect on the board. And I tried to map the pins like in that code but I am stuck now on this distorted image
Perhaps you have some ideas on how to get it working ?
below is the working arduino code and the platformio.ini env I created

-D TFT_RD=2
