11.1 QTouch Library

The QTouch® Library provides a simple to use solution to realize touch sensitive interfaces on most AVR® microcontrollers. The QTouch Library includes support for the Touch and QMatrix® acquisition methods.

Touch sensing can be added to any application by linking the appropriate 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 down-loadable from QTouch Library . For implementation details and other information, refer to the QTouch Library User Guide - also available for download from the website.
