Touch sensing can be added to any application by linking the appropriate Atmel QTouch Library for the

AVR Microcontroller. This is done by using a simple set of APIs to define the touch channels and sensors,

and then calling the touch sensing API’s to retrieve the channel information and determine the touch

sensor states.

The QTouch Library is FREE and downloadable from the Atmel website at the following location: http://

www.atmel.com/technologies/touch/. For implementation details and other information, refer to the Atmel

QTouch Library User Guide - also available for download from the Atmel website.
