Detailed Description

Maps raw TSC2046 X/Y readings to the printed button zones on the panel overlay.

The panel has LED 1/2/3 buttons, each split OFF|ON, plus a full-width BEEP zone. Boundaries come from measured touches on the actual panel, not the printed geometry – resistive panels are not perfectly linear.
