Fix issue #575

UncleRus commented 10 months ago

Sorry, but this is wrong fix. Voltage CAN BE negative. See datasheet 8.6.3.1 Shunt Voltage Register

KlsBecker commented 10 months ago

Yes, the Shunt Voltsge can be negative, but the issue refers to the Bus Voltage. See datasheet 8.6.3.2 Bus Voltage Register.

You are absolutely right I apologize for my inattention.

Thank you!
