Thank You very much for the instructions on how to start!!! What is max number of the "pattern"? And about that config string - should it be cfg=hi,hi,hi or cfg=qhi,qhi,qhi? To me it seems that Your suggested hi,hi,hi is telling - there is Hall sensor feedback and index signal, no quadrature. Is that correct?
