Thanks guys.

An Update:
For you Labview programmers only interested in looking at one input to count pulses to determine the rate of rotation, the WPI counter library works great. Just make sure you take the time to read the help file on the counter VIs thoroughly.
When I got to the shop earlier today the team programmer complained that the software based counter he had built couldn't keep up at high motor speeds. I explained how the FPGA offloaded this work to the hardware and the counter VIs in the WPI library took advantage of this capability. We tried them and they worked all the way up to the 4000 RPM speed with no problem. We found it helpful to use one of the low-pass filters from the PID library.
