3.3.1 Oversampling (Filter Level)

Oversampling defines the number of samples taken for each measurement. Higher oversample settings result in more samples for each measurement, which averages the noise. Measurement will take a longer time, which will impact response time. Start with the default value and increase or decrease depending on noise levels. The default value is 16.

Note: The minimum recommended ratio of Filter Level to digital Gain is eight. For example, if digital Gain is configured as two, then oversampling should be configured to at least 16.

Steps to Configure Oversampling

The oversampling value for Button N can be updated by writing in the Node Oversampling (FILTERLEVEL[n]) register. Refer to Configuration Summary for more details.
