Arduino ESP32 TFT test:

With special TFT_eSPI
Proposed ports modified
Then upload from Test_Touch_Controller.ino
Comes with error missing TFT_driver ILI9341 driver
Copied from original TFT_eSPI
Upload again, then missing touch.h file in extensions
Also copied from original
Then upload, no errors
Then serial monitor: x:8191 Y:8191 z:4095
setup_user.h modified to ST7796 driver

Same output

In setup_user.h
#define TFT_RST 12 modified #define TFT_RST -1
Then output x:0 y:0 z:4095

With sketch demo_3D_cube white screen
Tried different drivers, no success
Then command #define USE_SEPERATE_TOUCH_BUS out, then sketch will work with your Library.

Next test:

In the user_setup.h the line //#define TFT_MISO 12 is commanded out
Then upload the following sketch:

#include <TFT_eSPI.h>
#include <TAMC_GT911.h>
#include <DigitalRainAnimation.hpp>

#define TOUCH_SDA  33
#define TOUCH_SCL  32
#define TOUCH_INT 21
#define TOUCH_RST 25
#define TOUCH_WIDTH  320
#define TOUCH_HEIGHT 240

TAMC_GT911 tp = TAMC_GT911(TOUCH_SDA, TOUCH_SCL, TOUCH_INT, TOUCH_RST, TOUCH_WIDTH, TOUCH_HEIGHT);

TFT_eSPI tft = TFT_eSPI();
DigitalRainAnimation<TFT_eSPI> matrix_effect = DigitalRainAnimation<TFT_eSPI>();

void setup() {
  Serial.begin(115200);
  Serial.println("TAMC_GT911 Example: Ready");
  tp.begin();
  tp.setRotation(ROTATION_NORMAL);

 tft.begin();
  tft.setRotation(0);

  matrix_effect.init(&tft);
  matrix_effect.setTextColor(0, 0, 255);
  matrix_effect.setHeadCharColor(0, 255, 255);

  
}

void loop() {

matrix_effect.loop();


  tp.read();
  if (tp.isTouched){
    for (int i=0; i<tp.touches; i++){
      Serial.print("Touch ");Serial.print(i+1);Serial.print(": ");;
      Serial.print("  x: ");Serial.print(tp.points[i].x);
      Serial.print("  y: ");Serial.print(tp.points[i].y);
      Serial.print("  size: ");Serial.println(tp.points[i].size);
      Serial.println(' ');
    }
  }
}

Screen has the matrix affect and i have touchscreen output in monitor
