void qt_calibrate_sensing( void )
Arguments
Void
NOTE:
5.6.5.8
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
NOTE:
5.6.5.9
This function returns the delta value for a given channel.
int16_t qt_get_sensor_delta( uint8_t sensor_number )
Arguments
sensor_number
Return type
int16_t
NOTE:
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
Arguments
lib_sig_ptr

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.
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.
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.
