Changing PFI Lines

[Jwilson]

Hello, I am using a USB 6229 Board. I am trying to count a square wave signal with a counter input. My problem: my signal is wired to PFI15, I am not sure how to change my counter source to PFI15. In MAX I connect a function generator to PFI15 and select that channel as my source and see the counter change, I am not sure how to do this in .NET

Thanks JWilson

Hello,

Since it seems like you are able to do what you wanted to in MAX, I would suggest creating a task in MAX and calling it in Visual Studio using the following line of code: DaqSystem.Local.GetSavedTaskInfo("cDAQtask"); 

You also may want to look at the counter example that is shipped with DAQmx found at the following path:

<Documents>\National Instruments\NI-DAQ\Examples\DotNET4.0\Counter\Count Digital Events\CountDigEvents

I have also found some useful material for you in regards to using DAQmx in the .NET framework and included links below.
