Note: When disabling a sensor care must be taken such that all channels of the Sensor
are set to 1. If any of the channels are missed out, it will result in undesired behavior of
the Sensor.
disabled with a burst length value of 1, it will result in undesired behavior of the Sensor.
The touch_qm_sensors_calibrate API needs to be called whenever burst length is
updated for one or more channels before starting a new Touch measurement using the
touch_qm_sensors_start_acquisition API.
touch_ret_t touch_qm_update_global_param( touch_global_param_t *p_global_param )
This API can be used to update the QMatrix global parameters, with values different from
the ones initialized using touch_qm_sensors_init API.
touch_ret_t touch_qm_get_global_param( touch_global_param_t *p_global_param )
This API can be called to retrieve the QMatrix global parameters.
This API can be used to calibrate all configured Sensors.
Calibration of all Sensors must be performed when –

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.
