hi, i was looking at touchscreens and i saw that they have 4 cabels for the X and Y values. to connect them to the computer there was a little chip i was just wondering how this chip works. i would like to intergrate a small touch screen into my project but i will on need the X or Y so left to right fuction of the touch screen. so my aim is to replace the small chip which convter the 4wires in to a language that a pc can understand in to something a picaxe can do so i can use the touchscreen as a input on my project. anybody got any data sheets or in depth info on how touch screens work or a good idea on how to do this thanks.
