6. Capacitive Touch Sensing
The QTouch
®
library provides a simple to use solution to realize touch sensitive interfaces on most 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 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 Microchip website at the following location www.microchip.com.
For implementation details and other information, refer to the QTouch library user guide also available for download from
the Microchip website.
