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).

Page 2: Getting Started
2 Getting started 2.1 Programming the firmware for the Xplain board In order to get the QTouch board up and running the AT90USB1287 and ATxmega128A1 device mounted on the Xplain board needs to be programmed. The required firmware is included in the .zip file following this application note. For a detailed description about programming the Xplain board, please refer to application note AVR1921. - Page 3 AVR1908 AT90USB1287 device, and to power the QTouch Xplained & Xplain boards. Refer to Figure 2-2 to see how to connect to the PC. • Connect an USB cable to the Xplain board and the host PC. • If programmed correctly (see section Error! Reference source not found.), the board will register as a Human Interface Device (HID), so no driver installation is required for most modern operating systems.
