Re: Resetting Encoder

We discovered the behaviour of the index pulse accidentally.
One of the encoders on our robot was wired up to include the index wire, and the consequence was that we were only recording positions in the range [-1.0, 1.0] revolutions, i.e. phase wrapping. For a sufficently fast turning mechanism the signal can look similar to noise.
