If I had custom drivers for an instrument/device, how can I "import" them to Labview so that I can use it to communicate with the device and acquire data?
Thank you in advance
What does custom mean here. In a sense every device driver is custom in one way or the other, it just depends where you draw the line between what is custom and what is not, and if "not custom" means generic, provided with the system, anyone but your own, or anything you do yourself.
A device driver usually consists of a kernel driver and in order to access it from an application you need the user level API for it, which is best implemented in a DLL written in C/C++. Then it's "easy" to interface the DLL from within LabVIEW through the Call Library Node.
