I'm trying it with +-2V right now and it looks much better. I appear to be getting data in about a 10mV range now instead of 200mV, which is adequate for our purposes. I'll log some data for a few hours and see what it looks like and post that. Is resolution enhancement the same thing as oversamplin...

A battery in charge or discharge cycle should produce a fairly smooth curve, but I am not seeing that. The program currently ta...
