I have a Hall Effect switch that Im trying to use to measure the speed of a disk that has magnets in it at equal spaces around the disk. What Im trying to do is count the number of times the hall effect sensor triggers (when it passes a magnet) so that I can count revolutions per minute. Functionality is supposed to be an accurate tachometer. I have some experience with Labview, but after searching endlessly on this forum, and on the internet in general, I havent come across anything useful. A few tutorials, but explanation was very vague, and the programs dont work for me. I have a USB-6211 DAQ if that helps. I also need to see the frequency on a waveform chart for visual readings.
If anyone could help me on this, Id appreciate it.
Thanks!
P.S. Ive attached the one labview hall effect code that I did find, but it didnt help me very much. I do wonder if I cant adapt it to my uses.

Under Help, use Find Examples and navigate as hown in screen shot. All 4 examples will work with your hardware.

So what is that example supposed to do? Ive managed to get the program I have working but only so far. It gives me a waveform, and reads in data, but I have no idea what the numbers its logging represent, nor does it actually count the number of revolutions.
Explanation would be greatly appreciated.
Thanks.
