Specific Libraries have been provided for special devices, which are not covered as part of
Generic Libraries.
6.2 Devices supported
The following devices are covered by the Device Specific QTouch Libraries.
6.3 QTouch Library for AT32UC3L devices
ATMEL QTouch Library for UC3L can be used for embedding capacitive touch buttons, sliders
and wheels functionality into UC3L application. The QTouch Library for UC3L uses the Capacitive
Touch Module (CAT) that senses touch on external capacitive touch sensors.
This Section describes the QTouch Library Application Programming Interface (API) for QMatrix
and QTouch method acquisition using the AT32UC3L devices.
