Description
- Power Supply
I/O Touch Screen X+ plate Voltage supply
„ X axis Measurement: Supplies the voltage to X+ position input of the touch panel.
„ Y axis Measurement: This pin is used as the input for the A/D converter
„ Pen Pressure Measurement: This pin is the input for the A/D converter at Z1 measurement.
„ Pen Waiting State: Pulled up by an internal resistor (typ.10K ohm).
I/O Touch Screen Y+ plate Voltage supply
„ X axis Measurement: This pin is used as the input for the A/D converter
„ Y axis Measurement: Supplies the voltage to Y+ position input of the touch panel
