5. Capacitive touch sensing
The Atmel QTouch library provides a simple to use solution to realize touch sensitive interfaces on most Atmel AVR
microcontrollers. The patented charge-transfer signal acquisition offers robust sensing and includes fully debounced
reporting of touch keys and includes Adjacent Key Suppression® (AKS®) technology for unambiguous detection of key
events. 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 QTouch library user
guide - also available for download from the Atmel website.
