This lcd working via the code below with TFT LCD Mega Shield V1.0 . But problem is this, when i touch the screen just a little bit stronger, strange noises and shapes arises on screen. What is the problem you think?
Code: [Select]
#include <UTFT.h>
#include <UTouch.h>
extern uint8_t BigFont[];
UTFT        myGLCD(ITDB32S, 38,39,40,41);   // Remember to change the model parameter to suit your display module!
UTouch      myTouch(6,5,4,3,2);
int yy=0;
int xx=0;
int tus=0;
void setup()
{
myGLCD.InitLCD();
myTouch.InitTouch();
  myGLCD.clrScr();


  myTouch.setPrecision(PREC_MEDIUM);
  drawbutton();
}

void drawbutton()
{
 
    myGLCD.setColor(0, 0, 255);
    myGLCD.fillRoundRect (0, 0,120, 120);
    myGLCD.setColor(255, 255, 255);
    myGLCD.drawRoundRect (0, 0,120, 120);
   
       myGLCD.setColor(0, 0, 255);
        myGLCD.fillRoundRect (180, 0,300, 120);
    myGLCD.setColor(255, 255, 255);
    myGLCD.drawRoundRect (180, 0,300, 120);
   
    myGLCD.setBackColor(VGA_BLACK);
      myGLCD.setColor(VGA_LIME);
       myGLCD.setFont(BigFont);
    myGLCD.print("1.tus",0,60);
     myGLCD.print("2.tus",180,60);
   //   myGLCD.printNumI(yy,20,100);
}
void drawbutton2()
{
//  myGLCD.clrScr();
//  myGLCD.printNumI(xx,50,200);
  //  myGLCD.printNumI(yy,120,200);
    myGLCD.setColor(VGA_RED);
       myGLCD.print("TUS:",100,200);
     //  void drawbutton();
      myGLCD.printNumI(tus,180,200);
}

void loop()
{
  long x, y;
  while (myTouch.dataAvailable() == true)
  {
    myTouch.read();
    x = myTouch.getX();
    y = myTouch.getY();}
   
    if ((x!=-1) and (y!=-1))
    {


//     myGLCD.drawPixel (x, y);
    }
    if((x<120) and (y<120))
    {
      tus=1;
        drawbutton2();
    }
      if((x>=120) and (y<120) and (x<=240))
    {
      tus=2;
        drawbutton2();
  }

}


Screen also goes very well with  UTFT_Demo_320x240 (C)2013 Henning Karlsen example.
