How does the ADC Digi filter work in ESP32-C3?

[kabiskac]

Hi, I would like to use the ADC Digi filter in the ESP32-C3.

I set it up using

Code: Select all

adc_digi_filter_set_config

and

Code: Select all

adc_digi_filter_enable

but I am not sure whether it works and what it does because there isn't an example for it.

Can someone please explain it to me?

I want to know too. Where did you do now?

Have you looked at the TRM, specifically On-chip sensor and analog signal processing -> SAR ADCs -> Features -> ADC Filters, page 742 in the current version of the TRM? That explains how the hardware works and possibly also clarifies what the API does.
