Abstract:
A touch screen driver that can be used with a resistive touch screen includes an input/output module that supplies at least one input signal to at least one of a plurality of input/output ports of the touch screen and that generates at least one output signal, in response to the at least one input signal, and in accordance with at least one control signal. A controller module generates the at least one control signal and that generates a position signal representing a resolved position in accordance with a plurality of contemporaneous touches of the resistive touch screen.
