OK I got the Touch screen working with your sketch (I think this is your sketch) below.
It works nicely with my finger and with the plastic point of one of my plastic pencils (I took the lead out).
However, one of my other sketches that displays text (via fonts), doesn't work now. The screen is garbled up. Is there a text/font mode I have to switch into? Or does text and graphics mixed nicely on the screen?
Code:
//This example implements a simple sliding On/Off button. The example
// demonstrates drawing and touch operations.

(It was bad soldering of the connector between the display and pcb. Works now.)
