We ran the encoder class on the encoder with the resolution set to 256. We got roughly 25,000 from the encoder class. 25,000ticks x (60sec/min) / (256ticks/rev) = about 5,859 RPMs. Since this was a full speed minicim I'd say the data was valid and I'd say the encoder's resolution is based on rising (or falling) edge and not both. Otherwise the RPM data would not be right.

The beauty of this encoder is that we can set the resolution lower if there was a sampling rate issue, simply with dip switches.
