Another problem I have is when the controller is connected to a computer or something else the Vref is on a slightly different level. I had to add An external reference to the boards to do correct calibration.


Did you tried to cut wire +5V in usb cable? So +5 from usb and +5v from brain board do not mix..
I did that.


Nop, that was to easy, I didn't think about doing it that way
Good suggestion, that should do the trick as Well, but doing it my way the nanoboard stays unmodified but it needs and extra line of code.
