Copy/paste removed the tabs.
Show off!
It's not as elegant as your code, of course

But then you get scroll bars and who scrolls them down?
Quote:That's some pretty major movement... 4.35v when 100%, then down to 4.20 (still 100%?), and then suddenly 3.97v (91%)... would have to be a pretty major current spike... more than I would expect to see on a SBC... maybe the charge IC throttled down a bit because it was warming up? Either way, both your and VoxUnius's results suggest 3A isn't keeping up when the PBP is loaded up.
Quote:Are current measurements not working atm?
I see current measurements working when solely running from battery. I interpret my data that there is a huge current spike between two measurement points and current is always is 0 on the actual measurement points.
Quote:This is the sort of thing I get for the A64 Pinebook... negative when the battery is discharging, positive when the battery is charging... possibly negative if the external PSU couldn't keep up with the load. I was expecting to see something more interesting than zeros!

I assume if we disconnect the battery, then the Pinebook Pro will shut down on load. Basically, we can't disconnect the battery.
