Logging battery amps

How do you get the INA219 to log the amps/volts from the negative side? Every code out there predominantly uses the positive side to measure but for solar panels, etc you need both measures...I found a site that explained there was a bug in the INA coding which doesn’t allow it, but I wondered if anyone had worked around it?

Thanks! :-)

I've been having a play with platformio and visual studio code which was a bit of a struggle to get going on, more because of the Arduino IDE not really being totally C++. Platformio is, IMHO, well worth having a look at. The libraries used can be stored with the code so no more problems from updated libraries breaking the code in the future. Anyway, work in progress but it's here and working on a wemos lolin32 board should anyone want to have a play. Probably inefficient as I tend to cut and paste then fiddle til it works rather than actually be a clever coder Smile

Just tried measuring current low side and it made no difference, though you won't be able to read the voltage high side.
