SNSK pins are available on distinct ports. 5 Generic QTouch Libraries 5.1 Introduction ATMEL QTouch provides a simple to use solution to realize touch sensing solutions on a range of supported ATMEL AVR Microcontrollers. The QTouch libraries provide support for both QTouch and QMatrix acquisition methods. Touch sensing using QMatrix or QTouch acquisition methods can be added to an application by linking the appropriate ATMEL QTouch Library for the AVR Microcontroller and using a simple set of API to define the touch channels and sensors and then calling the touch sensing API’ ...
