Possibly. The interface should have an index pulse on it, could be labeled encoder.N.Z where N is the encoder enumerator if you are using more than 1. Use the halscope to search for it. If it is feeding one of the mesa boards, there should be an index pulse there, but I am not familiar enough with the 7i33 to know which pin, or even if it sends it on to someplace hal can access. To work, I would think it would have to. Have you tried to contact Peter (mesa) about this? He'll be far more knowledgeable than I can ever be.
