Adapting existing win usb driver for LabVIEW

I have a specific USB device that has it's own driver for Win7. It works fine in my .NET application, I'm using drivers functions (C++) to manipulate device.

Now I'm trying to get this device work in LabVIEW. Is there a way to somehow adapt existing driver for it? Or it is useless and I need to write completely new driver for LabVIEW?

For now I created a driver using "NI-VISA Driver Wizard" so that "NI MAX" and "NI-VISA Interactive Control" detect my device. But I don't know what to do next?

Solution

  • Compile the driver C source files as a dll.

    Then import the dll into LabVIEW.

    As highlighted by Prain, the following is an example describing how C/ dll can be used in LabVIEW
