Hi,
We are interfacing i.MX6SL EVK board to AD7877 touch screen controller and are using 3.5 inch Screen touch Panel. Touch panel x-axis size is 76mm and y-axis size is 61mm.
While touching on the panel the pointer(S/W pointer) is appearing 2-3mm away from the point of contact.
We would like to know, whether this is a S/W issue Or is it H/W issue (related to the calibration of Ad7877)?
Pls give your inputs
