Figure C-7 Touchscreen and keypad interface

The connection between the resistive elements of the touchscreen and J3, J8, or J10 is shown in Figure C-8. When the pen is down, the two resistive elements touch and form a four-resistor network. Measuring the voltages at the two dividers indicates the X and Y positions.
