Once the filter_callback is completed, the signal values will be processed by the Touch
Library. The measure_complete_callback function is then called with touch data
(channel_signals, channel_references, sensor_states, sensors structure) as well as the
Touch Status (sensor_states) and Rotor/Slider position (rotor_slider_values).
The touch_event_dispatcher API needs to be called as frequently as possible for the
Touch Library to process the raw acquisition data.
When raw data acquisition mode is used, once the raw acquisition data is available from
the CAT module for all the sensors, the measure_complete_callback function is
immediately called with acquisition data (channel_signals).
sensor_states and rotor_slider_values data are not updated by the Touch Library in this
mode.
This API will return error if a Touch measurement is already in progress.
One peripheral DMA channels must be provided using p_touch_dma for QTouch
operation.
touch_ret_t touch_qt_ sensor_disable(touch_qt_grp_t touch_qt_grp,
This API can be used to disable Touch measurement on a QTouch Sensor.
The touch_qt_sensors_calibrate API needs to be called whenever one or more Sensors
are
touch_qt_sensors_start_acquisition API.
Note: Care must be taken such that a valid Sensor ID corresponding to a QTouch Group
A sensor or QTouch Group B Sensor is provided.
touch_ret_t touch_qt _sensor_reenable(touch_qt_grp_t touch_qt_grp,
This API can be used to reenable a disabled QTouch Sensor.
The touch_qt_sensors_calibrate API needs to be called whenever one or more Sensors
are
touch_qt_sensors_start_acquisition API.
