Touchscreen input to digital circuit

  1. Nov 21, 2007 #1
    I'm trying to design a digital circuit which will accept input from a touchscreen. Does anyone know if a touchscreen is manufactured which has input/output cables which are meant to be read by a digital logic circuit? (yes, it'll be a very complicated digital logic circuit).

    Even if I can find a touchscreen isn't *meant* to be used like this, but the manufacturer publishes the specs (like the protocol used to display pixels on the screen, or the message sent when the user taps the screen), I may be able to strip cable and wire it into my circuit.

    If anyone could point me in the right direction, I would be very appreciative.

    Thanks!

    Not sure, but I've used these guys touchscreens before and they will probably design a custom interface if you need it (and want to pay for it).

    This is a pretty good wikipedia.org article on touchscreens, with links to manufacturer's websites at the end:
