Labview 8.5 Is this the correct way to measure frequency (to be converted to RPM) from a quad encoder? I am a bit confused as to what the "counter" input is on the Read function. I don't have a board attached to my computer now so I don't know what choices will appear. I want to sample the same A pulse that I use for the analog Read function and use it to determine frequency, compared to the 200kHz onboard clock. Note: I know this vi will not run right because of dropped data in the timeout case. My actual program runs in a loop until "Stop" and all data lines are looped through registers while in a waiting state. I was just trying to present the part of the code that acquires data.

Correct Way to get frequency from quad encoder?

OK, bringing this back from page 7 now. I have answered the questions. I have given the hardware, explained what I am trying to do. Can someone here look at the block diagram I posted and tell me if either it is right or it is wrong. I is either one or the other.
