Agreed :-) So:

What is the complete part number of the part you're using (including CPR, bearing type, etc)?

Were you reading counts from the FPGA and dividing by elapsed time, or reading the rate from the FPGA? Please post code if you have it.


@jhersh: (if you are following this thread) would there be any advantage, tolerance-wise, to change the sample size to an even multiple of 4 (say 12 or 8) so that the averaging would always take place over an integer number of cycles?
