How to identify the four terminals x+y-x-y+ or X1-Y2-X2-Y1 of resistive touch screen from its FPC/FFC connector if no datasheet is available. Do we have standard pin configuration for all the touch screens?
Secondly can we calibrate the touch screen with the microcontroller as a host itself without using any PC software? Then what should be the default coordinates after the system is powered on. I want the either corner to have 0,0 and so on..
Thanks in advance.
