Data Modul easyTouch General Integration and User Guide

This guide is a general assembly and user guide for Data Moduls projective capacitive touch screen solution called easyTouch. Since easyTouch is based on ATMELs maXTouch technology some specific information may only apply to those controllers. However, most of the information in this document applies for almost any projected capacitive touch solution on the market. To achieve an optimal touch performance it is necessary to follow most of the hints and advices although it is obvious that sometimes not all rules can be applied because of mechanical restrictions or cost reasons. Advanced noise suppression and signal processing algorithms in the maXTouch IC may be able to optimize the overall touch performance but a good mechanical and electrical integration of the touch system into the complete unit is the key factor of a good touch performance and a successful product in the market.
