How to read the error pin? #30

Open pinae opened 3 years ago

pinae commented 3 years ago

The firmware documentation names an error pin which changes to high if the deviation between the requested motor angle and the angle measured by the encoder passes a threshold which is configurable via USB. This pin would be very helpful to detect stalls. Could you please add information on how to use it and where it is located on the board?

That is a feature of the original smart stepper on which this is based on. http://misfittech.net/3-2a-nema23-smart-stepper/

Does this mean it's not usable with this implementation?

I would also want to use the error pin. Is it implemented?
