Library Configuration parameters for UC3L

The QTouch Library for UC3L provides a single configuration header file touch_config_at32uc3l.h file for setting the various configuration parameters for each method. The different configuration parameters corresponding to QMatrix, QTouch Group A/B and Autononmous QTouch sensors are listed in the Table below.
