Thanks a lot, everything is working now, using GitHub - Bodmer/TFT_eSPI: Arduino and PlatformIO IDE compatible TFT library optimised for the Raspberry Pi Pico (RP2040), STM32, ESP8266 and ESP32 that supports different driver chips

just a small issue with touch function, 2048 AND 4095 Z value appearing randomly (certainly hardware issue), i just add "if (z1 == 4095) return false" same for 2048 in touch.ccp / validTouch function.

For info lcdwiki_touch is not working with esp32, but is useless regarding the great Bodmer's work !

May I know how you made the ST7796s work with ESP32, I also having white screen.

below is the link of my 4" TFT with driver ST7796s detail

the same display did work on my Arduino nano & mega but just can't work on ESP32 board.
