The Atmel
faces on most Atmel AVR
offers robust sensing and includes fully debounced reporting of touch keys and includes Adja-
cent key suppression
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 chan-
nels 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.
