    Here is an example of how the connection would normally happen and what voltage we would expect. This follows Ohms Law and Kirchhoff's Voltage Law, no matter what you do you cant break these laws. On the Left the...

    Now I see what your doing. Rotating the shunt does not produce the same result as actually running current in both directions. You will not get the same result in the complete system. In the correct configuration...

    Differential mode will probably help but will not work with negative voltage, Steve0 can you provide any schematics on how the teensy and shunt are connected. Without some isolation or separate sources I dont see how...

    Please post on sketch of your circuit, the way you describe is fishy and could lead to magic smoke eventually. Any voltage applied below -0.3v will damage the micro due to the internal protection diodes on all pins. ...

    @brtaylor, will there be support added for the extra pins? I take it most PJRC libraries would have issues with the extra pins....

    Very nice, from experience you will have noise issues with the ADC's if you try to run SPI while sampling the ADC's which makes logging or running small screens a pita. What I ended up doing was using an external spi...
