4-Wire and 8-Wire resistive touch-screen controller using the MSP430

Resistive touch-screen films add more interface options to your projects. Here’s an app note from Texas Instruments on how to interface resistive touch-screens with MSP430 microcontrollers, but it’s good info for any chip:

This application report describes how to use an MSP4309 microcontroller 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.

  1. Hi sir,
    This is Aravind G, a 2nd year Mtech student from karnataka. Can you please send me this complete project. So that it will be helpful for my academic project

    Regards
    Aravind G

    1. If Aravind is representative of the current generation of tech students in India the rest of the world doesn’t have to be afraid of any competition from there.

      A second year tech student that don’t know what a app note is, and isn’t able to download two files by himself….. Come on! This must be a joke, right?

  2. They are all like that. I see Indians asking people on youtube and other websites to send them all the information they need. They don’t seem to put any effort to get the information they just want you to give it all to them. So ya. We don’t have anything to worry about as far as these guys taking over the engineering world.
