5.6.5.8
Recalibration may be useful if, for example, it is desired to globally recalibrate all sensors
on a change in application operating mode.
This function must be called only when the sensors have been configured and initialized.
qt_reset_sensing
This function disables all sensors and resets all configuration settings (for example, “qt_di”) to
their default values.
void qt_reset_sensing( void )
Arguments
Void

5.6.5.9
This may be useful if it is desired to dynamically reconfigure sensing. After calling this
function, any required sensors must be re-enabled, filter callback needs to be re-
initialized, and “qt_init_sensing()” must be called before “qt_measure_sensors()” is called
again.
In case of QMatrix, the burst lengths for all channels are set to zero.
qt_get_sensor_delta
This function returns the delta value for a given channel.
int16_t qt_get_sensor_delta( uint8_t sensor_number )
Arguments
sensor_number
Type
unit8_t
Comment
sensor id for which the delta is required
Return type
int16_t
Comment
The delta value of the sensor specified
NOTE:
?
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.
5.6.5.10 qt_get_library_sig
This function is used to retrieve the library version and signature from the library.
void qt_get_library_sig( qt_lib_siginfo_t
*lib_sig_ptr )
Arguments
lib_sig_ptr
Type
qt_lib_siginfo_t *
Comment
Pointer to the structure which needs to be
updated with the library signature
information
NOTE:

The function qt_measure_sensors() should have been called at least once prior to calling
this function.
