Re: Best way to measure period between pulses? Counters and FPGA

I am currently trying to do the same thing, using a light sensor to create a custom tachometer. As it has been explained to me (correct me if I am wrong) the crio FPGA has an integrater function built in, so even if pulses moving faster than 20ms can be measured. I calculated that on our shooter even with a 1 tick tachometer it will be sending a pulse every 1-2ms, which may be too fast for the AndyMark optical sensors, but I haven't checked too closely. However, it does seem like a good idea for certain high speed feedback.
