2 years ago Pin 19 should not be used as reset, that will be configured as SPI input MISO. Allocate and wire reset to another GPIO pin. Suggested connections:
// Generic ESP32 setup
#define TFT_MISO 19
#define TFT_MOSI 23
#define TFT_SCLK 18
#define TFT_CS 21
#define TFT_DC 2
#define TFT_RST 4 // Connect reset to ensure display initialises

2 years ago I will change them back like this. I think this is corresponding with what you sad...
// LED pin 3v // SCK SCK 18 // SDA MOSI 23 // A0 DC 2 // RESET 4 // CS 21 // GND GND // VCC pin 5v

2 years ago I have still a white screen.

2 years ago Run the sketch Read_User_Setup and check the serial monitor output is as expected. Post the output.

2 years ago If you use the User_Setup_Select.h header to decide which setup file to call up then you will not need to edit the User_Setup.h file.
Glad you have it working.
I have tested setup 7 and 47 and keep getting a with screen. I m not using the default wiring but I know it works by only using these librarys and pins
I rewired it with your default pins an than it was working but very slow, and it stopt working after a few second. I want to use the wiring like this. How should I config it?
This looks right to me, but clearly there is someting wrong.
