Arduino Mega2560 with ITDB02-3.2S - Odd touch problem

I have a Mega2560 with an ITDB02 Arduino MEGA Shield v2.0 and a ITDB02-3.2S. It all works well if I plug in the touch display while the Mega is running and the upload a sketch… But. If I power on the Mega with the display plugged in the touch functionality doesn’t work. The display works fine, but the touch is all dead. Any ideas?

#include <UTFT.h>
#include <UTouch.h>

extern uint8_t BigFont[];

UTFT        myGLCD(ITDB32S, 38,39,40,41);
UTouch      myTouch(6,5,4,3,2);

int CallActive=0;
int x, y;
int red = 0;
int n =0;
char stCurrent[20]="";
int stCurrentLen=0;
char stLast[20]="";

void setup() {
// Initial setup
delay(100);
  myGLCD.InitLCD(LANDSCAPE);
  myGLCD.clrScr();

  myTouch.InitTouch(LANDSCAPE);
  myTouch.setPrecision(PREC_HI);

  myGLCD.setFont(BigFont);
  myGLCD.fillScr(0, 0, 255);
  myGLCD.setColor(0, 0, 255);
  myGLCD.fillRoundRect (10, 130, 310, 210);
  myGLCD.setColor(255, 255, 255);
  myGLCD.drawRoundRect (10, 130, 310, 210);
  myGLCD.setBackColor(0,0,255);
  myGLCD.print("TEST2", CENTER, 147);
  Serial.begin(9600);
  Serial.println("StartUp");
}

void waitForIt(int x1, int y1, int x2, int y2)
{
  myGLCD.setColor(255, 0, 0);
  myGLCD.drawRoundRect (x1, y1, x2, y2);
  while (myTouch.dataAvailable())
    myTouch.read();
  myGLCD.setColor(255, 255, 255);
  myGLCD.drawRoundRect (x1, y1, x2, y2);
}

void loop() {
  // put your main code here, to run repeatedly: 
  while (true)
  {
    if (myTouch.dataAvailable())
    {
      
      Serial.println(n);
      n=n+1;
      myTouch.read();
      x=myTouch.getX();
      y=myTouch.getY();
      Serial.println("StartCall");
      if ((y>=130) && (y<=210))
      {
        if ((x>=10) && (x<=310))
        {
          waitForIt(10, 130, 310, 210);
          
          if (CallActive==0) {
            CallActive = 1;
            myGLCD.setBackColor(0,0,255);
            myGLCD.print("TEST", CENTER, 147);
          }
        }
      }
    }
  }
}

Turns out, that I don't even need to send a new sketch to the Mega... I just need to "restart" the LCD by unplugging it and plugging it in again...

Hi Michael,

I have the same problem, could finally solve it?

Thank you.
