Tested with ESP32-C3 and ESP32-C6 and ESP32-H2 Super Mini, Arduino IDE, modified TFT_eSPI 2.5.43, Board package version 3.0.3 and 3.0.4 and TFT driver ST7789 .

ESP32-C6 and ESP32-H2 are upgraded ESP32-C3, so the code of the library TFT_eSPI works here too with some modifications (but slower 40MHz ?). Remember: The code is only for testing and shows where the problems with (changed) espressif files are.

I modified two files, so "Processors/TFT_eSPI_ESP32_C3.c" is also included for ESP32-C6 and ESP32-H2 :

• TFT_eSPI.h
• TFT_eSPI.cpp

I modified two files, so ESP32-C6, ESP32-H2 and ESP32-C3 works for me:

• TFT_eSPI_ESP32_C3.h
• TFT_eSPI_ESP32_C3.c

This modifications works with all three processors ESP32-C3, ESP32-C6 and ESP32-H2.
