Hello.

I want to know about CapSense Smart-Sense.

Question:
How is the threshold parameters define based on Smart-Sense?
For example, do threshold depends on Diffcounts in first scan?

Best regards,

SmartSense calculates initial threshold values based on an expected signal (i.e. expected diff counts). This expected signal is calculated based on the finger capacitance value which you can specify in the CapSense component configuration settings.

SmartSense also monitors the noise in CapSense raw counts and uses this data to adjust threshold parameters if the noise is high.
