qt_measure_sensors

This function performs a capacitive measurement on all enabled sensors. The measured signals for each sensor are then processed to check for user touches, releases, changes in rotor angle and changes in slider position. The function returns the status of the Library as a combination of bit fields in an uint16_t value.

unit16_t qt_measure_sensors( uint16_t current_time_ms  )

Arguments	Type	Comment
current_time_ms	uint16	The current time in milliseconds

Return value(s)	Bit definition	Comments
QTLIB_NO_ACTIVITY	0x0000	No activity detected on any of the sensors
QTLIB_IN_DETECT	0x0001	At least one sensor is in detect
QTLIB_STATUS_CHANGE	0x0002	At least one sensor has changed ON/OFF state since the last call to `qt_measure_sensors()`
QTLIB_ROTOR_SLIDER_POS_CHANGE	0x0004	At least one rotor/slider has changed position since the last call to `qt_measure_sensors()`
QTLIB_CHANNEL_REF_CHANGE	0x0008	At least one reference value has changed since last call to `qt_measure_sensors()`
QTLIB_BURST_AGAIN	0x0100	Flag to indicate Multiple measurements needed.
QTLIB_RESOLVE_CAL	0x0200	Multiple measurements needed to resolve calibration. Call `qt_measure_sensors()` once again.
QTLIB_RESOLVE_FILTERIN	0x0400	Multiple measurements needed to resolve filtering. Call `qt_measure_sensors()` once again.
QTLIB_RESOLVE_DI	0x0800	Multiple measurements needed to resolve detect integration. Call `qt_measure_sensors()` once again.
QTLIB_RESOLVE_POS_RECAL	0x1000	Multiple measurements needed to resolve positive recalibration. Call `qt_measure_sensors()` once again.

Note:

1.
All sensors must be configured (using qt_enable_key or qt_enable_rotor or qt_enable_slider) and initialized by calling qt_init_sensing before calling this function.
