InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
This looks similar to what is available on the newer Dx family. The Arduino core documents this, so it may be worth reading through the source to see how it is achieved: https://github.com/SpenceKonde/DxCore/blob/master/megaavr/extras/Ref_Analog.md
