ESP32 and 2.4 inch tft plug to uno cant get the touch to work

Hello everyone I cant get this touch to work on my esp32 and the 8 bit display touch 2.4.

this is my code

#include <SPI.h>
#include <TFT_eSPI.h> // Includes the settings from your edited User_Setup.h

TFT_eSPI tft = TFT_eSPI();

// Array to store the 5 calibration values (must be saved after calibration!)
uint16_t calibrationData[5] = { 0, 0, 0, 0, 0 };

void setup() {
Serial.begin(115200);

// 1. Initialize the Display
// This reads your new pin definitions from User_Setup.h
tft.init();
tft.setRotation(1); // Set to landscape mode

// 2. Clear screen and display title
tft.fillScreen(TFT_BLACK);
tft.setTextColor(TFT_YELLOW);
tft.setTextSize(2);
tft.setCursor(5, 5);
tft.println("ESP32 Parallel Shield");
tft.println("Touch Calibration...");

// 3. Run the touch calibration routine
// This will display target points for you to touch
tft.calibrateTouch(calibrationData, TFT_MAGENTA, TFT_BLACK, 15);

// 4. Print and display the results
Serial.println("\n--- Calibration Data ---");
Serial.print("Copy and Save this data: ");

tft.fillScreen(TFT_BLACK);
tft.setTextColor(TFT_GREEN, TFT_BLACK);
tft.setCursor(5, 5);
tft.println("CALIBRATION COMPLETE!");
tft.print("Save this 5-number array: ");
tft.setTextSize(1);

for (int i = 0; i < 5; i++) {
Serial.print(calibrationData[i]);
tft.print(calibrationData[i]);
if (i < 4) {
Serial.print(", ");
tft.print(", ");
}
}
Serial.println();
}

void loop() {
// Test loop: Draw circles where touched
uint16_t x, y;

#ifdef TOUCH_CS
// tft.getTouch reads the calibrated position
if (tft.getTouch(&x, &y)) {
  // Draw a small point/circle at the touch location
  tft.drawCircle(x, y, 5, TFT_RED);
  Serial.printf("Touch at X: %d, Y: %d\n", x, y);
}

#else
// No touch functionality available
#endif
delay(100);
}

and I get this error

I am alittle stuck here is the tft.eSPI user.setup.h

can anyone help me please

The error and the internet are saying "8/16bit parallel display with touch" is not supported. Try using an additional library for touch, like TouhScreen.h or Adafruit_TouhScreen.h and TFT_eSPI.h for drawing.
