Q: I am using a resistive touch screen to interface to a Fez Hydra board. But I am seeing that are two cables coming out of the touch screen. One I understood that it is 4 wire (X1, X2, Y1, Y2). I am confused with the other cable as to what it is used for. I am attaching the picture of the touch screen. Please let me know how to prepare a connector for this so that it can be connected to Fez Hydra Board
