Damn I love McVitties. Can't beat a Tim Tam tho or a VoVo.
Well, I played with your code and got a demo working that I can use. Just has one menu which simply outputs to serial what button is pressed. I can work with this.

bool pressed = (p.z > MINPRESSURE && p.z < MAXPRESSURE);
if (pressed) {
// most apps use Portrait or Landscape. No need for all 4 cases
