Transfer data from c++ to labview and plot real time

[Teuntjuh24]

Hi Guys,

I'm new to labview. I have been looking at the forum for similar questions, but couldn't find any. Could someone tell / hint me what the best way is for transporting data (An array of integers) from a C++ function and plot it real time? I mean, the data (array) within the C++ function changes about ten times a second. Should I open a UDP connection between my C++ and labview and transfer a whole array and update this 10 times a second? Is this the best way to do so? If so, could someone hint me on how to do this.


Thanks,

Teun van Berkel

i've done some applications to transfer datas. 

there are some way:

1. socket.

some use the tcp or udp socket. one is server, others are client.

2. file read/write.

one writes into file, and the others keep read content. if new content comes, treat it.

...

In LabVIEW, you need to build a sub vi as a thread, which keeps to watch the socket or file.
 and use the queue or self-define event to notice the main treater.

hope it will help you.
