Re: Why are four states needed with Quadratuer encoders?
Thank you for the feedback. The colored wheel illistration was helpful. I still have a question. I looked at how you set up the code and I think I get it, but what edge should be set for interupt? For the machine to keep up with the state changes wouldn't you want to interupt both when it goes from white to black and from black to white?
