Keywords:TI application note? resistive touch-screen controller? low power?

This TI application note describes how to use an MSP430 MCU to drive and read a resistive touch screen. The hardware and software solutions provided enable the reading of user input through a 4-wire or 8-wire resistive touch screen with a low-cost low power customizable microcontroller. The reference design includes MSP430 software and hardware schematics along with a demonstration PC application. The design was implemented using an MSP430F2012, but it can easily be modified to use any other MSP430 with an ADC.
