But with the can encoded, that encoding has to be positioned very accurately in relation to the optos, yes?
What I was suggesting is that provided we know where the can is at one point in time, then no matter what the physical relationship was between that point and the optos, it could be aligned with the optos (as near as) perfectly by the software in the processor, which then provides the "hall" signals to the controller. And you only need one opto to do it. The second opto is to provide clockwise / counter-clockwise sensing.
Jeez, I hope that makes sense
