10. Capacitive Touch Sensing
10.1. QTouch Library
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 Atmel QTouch and Atmel
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: 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.
