Description

4 wire resistive touch screen mux break out baord, can be used with any graphical lcd in the back groung, features and usage vcc 5v out put: analog by touching the screen on any given point, you will get analog voltage on the corresponding axis. “x” axis: moving from left to right the voltage remains constant and moving from top to bottom the voltage varies, (select pin should be active heigh). “y” axis: moving from top to bottom the voltage remains constant and moving from left to right the voltage varies, (select pin should be active low). To get the accurate measuring axis of x and y, follow the instructions below: to get “y” axis data output: select pin should be ground to get “x” axis data output: select pin should be tied to vcc toggle select pin to heigh and low pulses to get “x” & “y” axis data correspondingly and get the out put analog volates of the corresponding axis.
