Digital Correlator dll Issue



I am complete newbie labview but recognise the power the labview software and the forum to help do some great work.


We have a digital correlator from They say it compatible with labview but I dont have a working sample to use. We were hoping that someone could help get this working or at least get us on the right track. We did someone try this on an example from this forum but no luck so far. I really hope someone can help. Its urgent.

Hi Alan, I'm Paul from Applications Engineering at NI and I will be helping you with these issues.


LabVIEW certainly does have the ability to call external DLLs through our Call Library Function node.  I don't know how much you've read up on this, but I would recommend checking out the following articles and seeing how far you get on your own.  Even after getting a grasp of our Call Library Function node, you are going to have to understand the DLLs that you are using, and their approriate inputs and outputs.  Rolfk's reply may be something useful down the road if you are having syncing issues with your DLLs.


We also have an example in our built-in example finder in LabVIEW that demonstrates how to work with DLLs.  This can be found by going to 'Help'>'Example Finder'>'Search'>"Call" and then opneing that Example VI.


I would recommend using all of those resources to read up some on using DLLs in LabVIEW and trying to work with those files you posted.  If you still have trouble, then we will address those issues as they come up.


Good luck,
