Setup for T-QT Pro Display is black
-
Hi People,
someone can give me a small hint to get the Display working ? My T-Display S3 is working fine.
Something else to change ?Thanks for help

Can you check if your sketch does this:
#define PIN_LCD_BL 10
pinMode(PIN_LCD_BL, OUTPUT);
digitalWrite(PIN_LCD_BL, HIGH);Unbelievably their demo LCD.ino sketch turns this OFF at line 25.
I do not have a T-QT Pro to test but if this fixes it, I will file an issue in their repository against it.

Hi Terry
thanks for your reply i checkt it looks okay but it´s still not working.
Maybe it´s something with the SPI idk.
Had so many Problems with the TFT_eSPI Libary so i set it "UserDefined".
Currently i set it to #include <User_Setups/Setup24_ST7789.h> // Setup file for DSTIKE/ESP32/ESP8266 configured for ST7789 240 x 240 that is working with the T-Display.
I think i have to change something there. (Backlight of Display is on.)
I wrote everything in the Arduino IDE because in Studio Code i get realy strange compiler Error´s with one of my used Lib´s.So many Problems xD

@ardymoon The LilyGO products are poorly supported, compared to M5Stack or Arduino.
You can go here:
https://github.com/Xinyuan-LilyGO/T-QT/issues
And start a new issue to get LilyGO support.I may have misspoken:
The LCD_BL may be active LOW, who knows?
On the LilyGO T-Display S3 it is active HIGH! -
Hey,
found my Problem "stupid me" used Arduino IDE 2.0.2 not 2.0.3 xD
Also Updated the Lib for the Display now it´s working.
