This device is not directly supported and I also haven't found any info on any tries to run it. You will have to program it yourself then. You basically have 2 options here:

1/ Use low-level VISA functions to communicate through USB. You will need to find out on how this device works (how to format commands)

2/ I suppose that the manufacturer provides you with some drivers and/or control software for that. If those are DLLs you can try to call them in LV and use the device this way.

Let us know if you've managed to get it working

Hi!

I found some code in C !

http://thirtysixthspan.com/TrackerPod/

I think with this TrackerTools-1.3.0.tar.gz or with this TrackerTools-1.0.0.tar.gz i can controll it.

And as i know LabView support C codes. Just i don't know how to use C-code in LabView... Is there any tutorial for it?(i dind't find)...

Thanks: Kolos

Can't i directly write C code in Labview? Do I need DLL-s?

Thanks:Kolos

Some targets do support "Inline C node" which lets you write C code directly on bloack diagram. This is not availible on PC, though. You can use CIN (Code Interface Node) - in LabVIEW open Examples Finder and search for "CINs".

The webpage you are linking to says: "TrackerPod Drivers for Linux" so those are linux drivers. Theoretically you could try a Windows Linux/Unix simulator (like Cygwin) or to recompile them for Windows. However, both of those are quite complicated and don't guarantee it will work.

Maybe you could also find the part of code responsible for communication/control itself and appy it in a Windows program? You have to figure out what commands are being sent/received.

You could also ask the producer if they can provide you with any specification or drivers.

Let us know how it goes.

Don't worry, I was also looking through their website and also didn't see it.

Let us know if you manage to get it working. If you elaborate a nice LV driver, maybe it's worth posting it somewhere?

If it will work i post it certainly...

now i play with: how to use DLL-file in labview...

i think the DLL i found isn't good...

It have 4 function: -DllCanInloadNow()

-DllGetClassObject()

-DllRegisterServer()

-DllUnregisterServer()

So i think i must make myself the DLL from the files...
