Hi,
I want to drive a 4 wire resistive touch screen with ADS7846 but can't find good resource about it and the texas instruments web site data is poor about reference schematic and free sample also topics in edaboard about this IC don't have useful information. I drawn a schematic to use this IC with ARM MCU, please review my schematic for mistakes :
