Touch screen controller

pluuuto · Aug 2, 2008

Hi All, Im planning to use resistive touch screen for my next project. I try to save the cost so I wish to do the controller my self. I tried googling but canot find the schematic. Does anyone know how i can built it?

Hi, if you go to: http://www.circuit-ed.com/-EasyPIC5-Development-KIT-P12C15.aspx, then scroll down to EasyPic5 manual and go to page 25 it gives you a schematic. Their prices seem to be pretty reasonable for the touchscreen itself and GLCD.

Hope this helped,
Ed

Basically what is needed is a ADC. Take a look at the AD7877 datasheet.
