1 Introduction

QTouch Xplained is an easy to use low-cost evaluation kit, which demonstrates

QTouch and the QTouch Library features. The QTouch Xplained utilizes the Xplain

to do this.

The kit demonstrates how a QTouch solution requires only a very simple circuit

design and a minimum of external components. It includes support for eight

QTouch channels: a slider (3 channels), a wheel (3 channels) and two keys (1

channel each).
