Abstract:
A method for interfacing with a capacitive touch screen is disclosed. The method includes charging an internal capacitor in the touch screen, which internal capacitor is disposed proximate a fixed location on the touch screen and is capable of changing in response to a touch at the specific location. After charging, the charge on the internal capacitor is transferred from the touch screen and the value of the charge on the internal capacitor then determined.
