Need some advice regarding Touch panel code

Hi
Guys, trying to figue out for few days now,i have a display with resistive touch, problem is, that display is working fine, i`m using hardware mega spi pins, and utouch library for touch.
The problem is that i only receiving through serial coordinates x319, y 239.
Does any one came across any other library that might work with XPT2046, or is there any way i can use utouch?? tried calibration etc nothing works, i thought that this is hardware fault, but tried allready 3 different displays with the same chip and problem seems to be permanent.

My basic code to check touch:

#include <UTouch.h>
UTouch  myTouch( 14,15,16,17,18);

int x, y;
void setup()
{
  Serial.begin(9600);
  myTouch.InitTouch();
  myTouch.setPrecision(PREC_LOW);
}

void loop()
{
  while(true)
  {
    if (myTouch.dataAvailable())
    { 
      myTouch.read();   
      x=myTouch.getX();
      y=myTouch.getY();
      Serial.print("x: ");
      Serial.print(x);
      Serial.print(" y: ");
      Serial.println(y);
      delay(100);
    }
  }
}

Also found this library, but don`t know how to use is as there is no examples for it.

Someone suggest to use ADS7846

thanks for any help.

void loop()
{
  while(true)
  {

Why are you running an infinite loop inside an infinite loop()?

This is how the library was written.
