Use C code in LabVIEW?

[Z.Wei]

Hi all,

I'd like to know that if I have a C code with some input and output, how can I embed my C code into LabVIEW?

I did some research and find out there's a CIN (code interface node), however it's no longer supported at least from LabVIEW 2010?

I'm using LabVIEW 2012 on Windows 7, so anyone has ideas on this?

Thanks for pointing me to the right directions!

Is it compiled into a DLL? There is a "Call Library Function Node" that you can use to input and output to a DLL.

See this KB article http://digital.ni.com/public.nsf/allkb/DCB90714981A1F148625731E00797C33

I know how to play with .dll with the call library node, however I'm interested to know how a C file can be used in Labview

The code interface node was indeed deprecated after 2010.

Thanks for pointing that out. So how can I use a C file in LabVIEW?

You can't. You can call a .dll.  The "formula node" has some "C like" syntax for calculations and logic, but those are your options.

Thanks. Probably I need to compile it to a dll before using it. 🙂

Not just probably! It's the most straigtforth and simple possibility.
