This API can be called to retrieve the QTouch Group A or Group B global parameters.
This API can be used to calibrate all configured Sensors.
Calibration of all Sensors must be performed when –
touch_ret_t touch_qt_sensors_start_acquisition(touch_qt_grp_t touch_qt_grp,
void (*measure_complete_callback)( touch_measure_data_t *p_measure_data ))
This API initiates a capacitive measurement on all enabled QTouch Group A or Group B
sensors depending on the touch_qt_grp specified.
When normal acquisition mode is used, once the Touch measurement is completed on all
the QTouch sensors, before processing the raw acquisition data (channel_signals), a
filter_callback function is optionally called by the Touch Library.

All the Sensors have been configured using touch_sensor_config API after
initialization of the Touch Library.
A sensor or a group of Sensors have been disabled or re-enabled.
