Overview of QTouch Library API for UC3L
The diagram below captures the high level arrangement of the QTouch Library for UC3L API.
The QTouch Library for UC3L API can be used for Sensor configuration, Sensor Acquisition
parameter setting and Sensor Enable/Disable operations.
Based on this input Sensor
configuration, the QTouch Library takes care of the initialization, configuration and acquisition
data capture operations using the CAT module. The UC3L CAT module interfaces with the
external capacitive touch sensors and is capable of performing QTouch and QMatrix method
acquisition. For an Overview of QMatrix and QTouch Capacitive Touch acquisition, refer
Section
5.2.
The raw acquisition data from the CAT module is processed by the QTouch Library.
The
Adjacent Key Suppression (AKS), Detect Integration mechanism, Drift compensation and
Automatic Recalibration components of the Touch Library aid in providing a robust Touch
performance. Once the raw acquisition data is processed, the individual Sensor Status and
Wheel/Slider position information is provided to the user by means of a measurement complete
callback operation.
