Touch screen 4-wire interface

[Demon]

Hi,


Has anyone had any success in connecting a touch screem using 4-wire technology to a PIC?

If you have, code snippets as well as a schematic would go a long ways. Here is what I've found so far, the 4-wire circuitry is the larger box across the center. It has 4 wires from the touch screen, and 6 wires to the PIC.

I'm told this circuit is pretty much 'good', for what that's worth. What I lack is the code to interpret the information at the PIC end. BASIC would be nice, but I'd take Assembler code at this point.

Thanks, and have a nice day!
