ESP32-S3 UNO and TFT shield screen

Postby Kon stan » Fri Oct 17, 2025 5:36 pm

Please help!

I have ESP32-S3 UNO development board. I try to use RM68140 TFT screen to mount it as shield.
Using TFT_eSPI library. Modified files User_Setup.h and User_Setup_Select.h to enable RM68140.

Unfortunatley it does not work and crashes on
tft.init();

I also tried TFT ILI9341 - the same result.

If I use Arduino UNO R4 both Minima and WiFi, it works nicely.

Thanks!
