Detailed Description
An App example guiding the user through the steps needed to (re)calibrate the touch controller.
After the user presses each of the four corner for calibration the program turns into a very simple drawing application until the Done button is pressed.
The purpose of this example is to show how to (re)calibrate the touch controller if that is ever needed.
