Hi, I have been trying to figure out the 4 wire resistive touch screen concept from last few days. Though I have kind of understood the basics of how it operates, but need some jump start on the PBP code side of it. I am struggling to understand on what to do exactly to get the X,Y co-ordinates, how to turn an analog input pin to provide full 5V? may be there is a separate circuit to it or not. A brief idea of the code to start with will be a great help, I have few 16f676 to play with and will try them to get the ball rolling. Thanks
