6.3.15.2.6 hysteresis_t
Enumeration
Use
Hysteresis_t
Defines the sensor detection hysteresis value. This is expressed as a
percentage of the sensor detection threshold.
This is configurable per sensor.
HYST_x = hysteresis value is x percent of detection threshold value (rounded
down).
Note that a minimum value of 2 is used as a hard limit. Example: if detection
threshold = 20, then:
HYST_50 = 10 (50 percent of 20)
HYST_25 = 5 (25 percent of 20)
sensor_type_t
Define the type of the sensor
aks_group_t
Defines the Adjacent Key Suppression (AKS) groups that each sensor may be
associated with
AKS™ is selectable by the system designer
7 AKS groups are supported by the library
Comment
When Raw acquisition mode is used, the measure_complete_callback
function is called immediately once fresh values of Signals are
available. In this mode, the Touch Library does not do any processing
on the Signals.
position values are not updated in this mode.
When
measure_complete_callback function is called only after the Touch
Library completes processing of the Signal values obtained. The
References, Sensor states and Rotor/Slider position values are
updated in this mode.
