10. Capacitive Touch Sensing
The Atmel QTouch Library provides a simple to use solution to realize touch sensitive interfaces on most
Atmel AVR microcontrollers. The QTouch Library includes support for the QTouch and QMatrix®
acquisition methods.
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:
www.atmel.com/qtouchlibrary. For implementation details and other information, refer to the Atmel
QTouch Library User Guide - also available for download from the Atmel website.
