Screen ESP32-2432S032C-I and User_Setup.h

[Stryke68]

Hello,

I currently have an ESP32-2432S032C-I display, but no matter which configuration I test in the User_Setup.h file, the screen remains black. This is the display in question:
ESP32-2432S032C-I

3.2" inch ESP32 Display ST7789 IPS TFT LCD Module ESP32-2432S032C-I Capacitive Touch Screen 240x320 ESP-Wroom-32 Dev board.

I can upload code (even a very simple “hello world” display) but the screen stays black. I believe my User_Setup.h configuration is not correct. Despite numerous online searches (as well as checking the configurations provided by TFT_eSPI), I haven’t been able to find the right settings.

Since the display is fully integrated with the ESP32, it’s difficult to determine how the ESP’s pins are assigned to the various functions (CLK, CS, RST, MOSI, MISO, etc.). I did find some schematics that provide certain details (e.g. CS = 15, SCK = 14, DC = 2), but not everything! (and I'm not sure I understand the diagram correctly...)

The display is in good condition and works – it even came with demo code that worked when delivered. I power it via my PC’s USB, and the display generates its own 3.3V, which I have verified.
TFT_eSPI 2.5.43

Does anyone have any suggestions or ideas on how to correctly configure it?
Thanks a lot

By reviewing the schematics and some example code found here Tinytronic (I had it in front of me though...),
I managed to get my screen working with the following settings in my User_Setup.h file
I hope this will be useful to others.
