Preface

Atmel® QT2 Xplained Pro kit is an extension board that enables the evaluation of a mutual capacitance touch surface using the Peripheral Touch Controller (PTC) module. The kit shows how easy it is to design a capacitive touch surface solution for the PTC without the need for any external components. The kit includes one board with a 4 by 4 touch surface and a 7 by 7 blue LED matrix for a visual feedback of the touch.
