Touchscreen PS2 Adapter, EZscreen L@@K
I recently purchased an LCD that had a built in touchsceen, but no touchscreen controller , I wanted to know what those 4 pins did. After research I found that they are axes (x1, x2, y1, y2) but I couldn't find out how to wire then into ps2 or Serial, until I came across this.
My question is if I were solder the 4 pins to the pins located on the ps2 device, and load thier drivers would everything work as normal. Is this a fix to possible touchscreen problem, or is there a way I can wire one of theses ps2 boxes myslef. Please let me know ASAP.
I highly doubt that would work. If you could just plug the 4 pins into the ps2 port, why would they have touchscreen controllers?
The 4 pins are are just power in and out for the x and y axes. The controller calculates the position based on the resistance on the x and y axes, and calculates the position and emulates a mouse.
Like LCD screens, the controller is the expensive part
an lcd tocuhscreen controller should cost around 50 USD ....
Just got off the phone with EZscreen, and they claim that if a Touchscreen is Analog Resistive and not Analog Matrix, the ps2 and serial controller will work . This is great news for anyone who is looking to fix older touchscreens. Just thought I'd let you all know.
