How to get power supply mode?
Is it possible to know whether LoPy is running from USB or a battery connected to an extension board like PySense or PyTrack?
@jcaron Thanks, will check values.
@bmarkus Indirectly, when you read the voltage from the Pysense, you can find out if you're on USB or on the battery based on the voltage read. Don't have the values at hand, but if you get something like 4.7V you know you're on USB, while if you get 4.2V or below you're running on battery.
Not sure if there's another more direct way, or if the voltage is different based on actual presence of a battery, though it should be quick to test the two cases.
