CAN with LabWindows

[Eric Paulin]

Hello everyone,

I'm currently using labview to build application that communicates with a
device using NI-CAN. I was wondering if I could use Labwindows instead to
build my applications cause I'm having a hard time with NI-CAN (and the PCI
card). Has anyone tried this? or have any experience with it? I need some
feedback. I know that I can program the CAN in C and that the nican.h file
exists but I have to learn how to use it.


Thx!!

Eric:

The Readme.txt file that installs with NI-CAN (under NICAN\Langint\) contains some information on using NI-CAN in environments, including LabWindows/CVI. I suggest you get the latest version NI-CAN, 1.3. This version contains a Function Panel (Instrument Driver) that makes the using NI-CAN in CVI easier.

Just like to mention that in my version (1.4), there is no on-line help with the function panel.

Eric,

One other item to consider. I noticed that you said, "... I'm having a hard time with NI-CAN (and the PCI card)". If this is referring to some sort of hardware/driver problem, then it is likely that switching to CVI will not solve the problem. Perhaps the most common hardware problem these days is that the driver is not supported under Windows2000 (but it is coming shortly). At any rate, if the problem you had was more hardware related instead of programming technique, then switching to CVI might not be a solution.
