Find average frequency from a digital waveform

[Justin D]

Hi olsont,
I don't think that there is an example that does exactly this but you should be able to modify an existing example to do this pretty easily.  One that you may want to look at is in the example finder under HW Input and Output->CompactRIO->FPGA Fundamentals->Frequency Measurement->Count and Period-cRIO.lvproj.

Are you using the 9421 in a Compact RIO chassis?  Are you sure that it's not compact DAQ or USB?  If you have the RIO driver installed you should have this example installed automatically.
