ABSTRACT:
A method for reading a position of a wiper on a potentiometer, comprising the steps of (A) charging a capacitor connected to a wiper terminal of the potentiometer, (B) discharging the capacitor through a particular terminal of the potentiometer, (C) measuring a first time taken to discharge the capacitor from a first voltage to a second voltage, (D) recharging the capacitor, (E) discharging the capacitor through another particular terminal of the potentiometer, (F) measuring a second time taken to discharge the capacitor from the first voltage to the second voltage, (G) reading the position of the wiper by calculating a ratio of the times measured in steps (C) and (F).
