DASport PCI-20450P-24 Labview driver?

[Setu]

Can anyone help me please. I am a novice user of labview. I have to interface Intelligent Instrument's Dasport (model above) with labview. I know I need a labview supporting driver (or do I?). Does anyone have one? Or can anyone point me in the right direction how I should go about creating it? I need a starting point.

I am a third year software engineering student, and I am doing this as part of my internship. I am studying labview as I am posting this message. I will appreciate any help.

There are a couple of different solutions for you. Texas Instruments (manufacturer of the DASport) sells a Data Aqcuistion Virtual Instrument Library for $99 at http://www.instrument.com/pci/labview.asp. This would probably be the easiest solution for you since all the work of creating vi's to perform the functions you want are made for you. I have not used their hardware or the LabVIEW vi's so I can't comment directly on it. However, LabVIEW also has the ability to call dll's and code interface nodes which would allow you to interface with their hardware driver if you knew the proper functions to call.

In the future, I would recommend using National Instruments data acquistion hardware because the ease of programming it from LabVIEW, Visual C++, Vis
ual Basic, etc. Hope this was helpful for you.

Thanks for your response. I am now looking into the VI library for $99 by Texas Instrument. However I am not sure if my DASPort falls under the PCI-20000 series? If it does, great, I'll buy it!. However, if it doesn't, do you know where I can get more help on Labview's Code Interface Library. I have got a list of function calls in C, but I don't really know how to implement the Code Interface Library. I also have the required DLL provided by Texas Instrument. But how do I put it all together? Is there any documentation regarding this that you know of?
Thanks again, I really appreciate your help.

There is some documentation in the LabVIEW Help for the Code Interface Library. If you can call to their DLL that would probably be easier than using CIN's (Code Interface Nodes). The main thing with calling DLL's is sending the right parameters to it. So if they have any documentation for the DLL that would be helpful. There are also some examples in the LabVIEW Help showing how to call to Windows DLL's. If you need more advanced help I'd also recommend searching here on Developer Zone. Hope that was helpful.
