Using the init_clock() in main.c and clock.c files,
Set the CAT_CLK Clock to appropriate value.
Using the touch_config_at32uc3l.h configuration file,
Set DEF_TOUCH_QTOUCH_GRP_A = 1, if QTouch Group A is to be used.
Set DEF_TOUCH_QTOUCH_GRP_B = 1, if QTouch Group B is to be used.
Set all QTA_xx (if Group A is enabled) to appropriate values.
Set all QTB_xx (if Group B is enabled) to appropriate values.
Set all TOUCH_xx macros to appropriate values.
(This includes 1 peripheral DMA Channels required for QTouch operation.)
In the main.c file,
Set the desired measurement_period_ms for Touch measurement.
The API Sequence below must be repeated for Group A and Group B when both the
Groups are used at the same time. The first argument to the API
TOUCH_QT_GRP_A or TOUCH_QT_GRP_B distinguishes between Group A and
Group B operations. Separate Filter and Measurement complete callback functions
must be provided for Group A and Group B Sensors.
