We set the DistancePerCount property value to 1. That gave us the rate in Hz.
We only used it to measure the RPM of our shooter, so it works if you don't actually need the distance.

I actually like Alan's method better. Let the FPGA do the calculation.
For a 250 pulse encoder 1/250 * 60 = distanceperpusle.
GetRate will then yield RPM's direclly.
The one thing that no one ever list in scouting but is one of the most important factors is reliability. I don't care if the robot scores a hundred balls a match if I can't count on you being out there for the next three because it's a fragile as china. - Koko Ed [more]
