ESP32-S3 Driving ST7701S Display Problem

[jerrylong-km]

Hi Guys
I am trying to use ESP32 driving 6" ST7701S Display.
This is the connection of ESP32 and Display

This is the schematic

This is my testing code:
ST7701S_LvglHelloWorld.zip
The BackLight is on when power-up, but shows nothing, could anyone help me to find out the problem? Thanks

My "Arduino_GFX_Library" version is 1.3.1

It seems that new version of GFX Lib does not support ST7701S anymore?

I have used Arduino_GFX_Library 1.4.7 (latest version), and tested type of st7701 for type1 to type9, none of them works for my display.

anythings else that I can try?

I was able to use the below code to get my ST7701 display working... kind of. It's irregular but maybe you can build off this:

#include <Arduino_GFX_Library.h>

Arduino_XCA9554SWSPI *expander = new Arduino_XCA9554SWSPI(
  PCA_TFT_RESET, PCA_TFT_CS, PCA_TFT_SCK, PCA_TFT_MOSI,
  &Wire, 0x3F);

Arduino_ESP32RGBPanel *rgbpanel = new Arduino_ESP32RGBPanel(
  TFT_DE, TFT_VSYNC, TFT_HSYNC, TFT_PCLK,
  TFT_R1, TFT_R2, TFT_R3, TFT_R4, TFT_R5,
  TFT_G0, TFT_G1, TFT_G2, TFT_G3, TFT_G4, TFT_G5,
  TFT_B1, TFT_B2, TFT_B3, TFT_B4, TFT_B5,
  1 /* hsync_polarity */, 50 /* hsync_front_porch */, 2 /* hsync_pulse_width */, 44 /* hsync_back_porch */,
  1 /* vsync_polarity */, 16 /* vsync_front_porch */, 2 /* vsync_pulse_width */, 18 /* vsync_back_porch */
);

Arduino_RGB_Display *gfx = new Arduino_RGB_Display(
  // 2.1" 480x480 round display adjust as needed
  480 /* width */, 480 /* height */, rgbpanel, 0 /* rotation */, true /* auto_flush */,
  expander, GFX_NOT_DEFINED /* RST */, TL021WVC02_init_operations, sizeof(TL021WVC02_init_operations));
