ESP32-3248S035C with GT911 touch chip not working

[eagl1]

Hi,

I have this module which is using ST7796 display driver and GT911 capacitive touch driver.

It come with lvgl example from the manufacturer. So I tried to upload a code with the Arduino IDE.

1. I set everything in the User_Setup_Select.h
2. I'm using these pin settings which is exactly what is in the schematic:

// for ESP32-3248S035C with GT911 touch chip board
#define TFT_MISO 12
#define TFT_MOSI 13 // In some display driver board, it might be written as "SDA" and so on.
#define TFT_SCLK 14
#define TFT_CS   15  // Chip select control pin
#define TFT_DC   2  // Data Command control pin
#define TFT_RST  -1  // Reset pin (could connect to Arduino RESET pin)
#define TFT_BL   27  // LED back-light

The schematic:

I tried to upload one of TFT_eSPI examples, no errors, the code uploaded successfully but the display is blank and nothing is working. I uploaded a code to test the onboard LED and it works.

One thing I used now is that I uploaded a code from this website:
https://nightly.openhasp.com/

It uploaded, and the display lighted up but I think there is no graphics in that binary.
