Simple test sketch for UTouch library

Here is a simplest touch screen test sketch (display X,Y on serial) using UTouch library for common Arduino LCD shield.

#include <UTouch.h>

UTouch  myTouch( 6, 5, 4, 3, 2);

void setup()
{
  myTouch.InitTouch();
  myTouch.setPrecision(PREC_MEDIUM);
  Serial.begin(115200);
}

void loop()
{
  while (myTouch.dataAvailable())
  {
    myTouch.read();
    long x = myTouch.getX();
    long y = myTouch.getY();
    if (x != -1 && y!=-1 && x != 319)
    {
      Serial.print("X=");
      Serial.print(x);
      Serial.print(" Y=");
      Serial.println(y);
    }
  }
  delay(20);
}

Tested with XPT2046 / ADS7843 touchscreen driver on Arduino MEGA.
