Thanks for the reply, you wouldn't happen to have a working example to get me started or suggest what VI to use for measuring Frequency ??
Also if I choose to add more Channels what is the best way to do it ?
I did the copy and paste thing for the existing example VI and just changed the Channel's, I had 4 Channels running but it seemed very sluggish after reading some more I found that I could add more Parameters to the existing "Call Library Function Node" the short story is that it did not work LV Crashed... what is the correct way here ?
I have searched NI for examples and found a several, but they vary from not so complex to very complex, and some of the functions and Block's etc could be (maybe) removed to simplify them back to basics and still work but that I am not to sure about, this is all Discovery Channel stuff for me at the moment... Yes Help is Needed, btw My input Signal is 0-5V Square wave ... there will be no AC stuff yet !!
would you mind deleting my previous post ..logged in would help ... DOH !
