Hi All,
First post here and need some advice.
I am working on a project using a Teensy 3.6 and one of the things I am required to do is read the voltage from a current shunt fitted to a light aircraft.
The current shunt is a 50A shunt that provides 2 output wires to read the current passing through the shunt. The value will be between -2.5v and +2.5v depending whether the battery is charging or discharging. So if all the electronics are pulling 50amps then the output from the 2 wires will be -2.5v. If the battery is charging at 50amps then the value will read +2.5v.
I have tested it with a multimeter and sure enough, it does put out + and - voltage depending on direction. The wires are labelled as + and - on the shunt.
How would I connect these 2 wires to the Teensy and how would I read that type of voltage?
Any help would be much appreciated. Many thanks in advance.
