Hi There,

 

Does anybody know how to write a function block with LabVIEW?  Something like those in Real-Time VIs>>Function Blocks>>.

 

Thank you very much in advance?

Hi qing,

 

seems you need to go through all those free LabVIEW beginner courses offered by NI.com!

 

Start here: www.learnni.com or here

Assuming you are referring to these specifically...

http://www.ni.com/white-paper/7339/en/

...then the answer is that it is nearly impossible to make a new one. However, there is really nothing all that special about them. They are essentially normal subVIs (which you can learn about from the other links) that just happen to have certain terminals bound to shared variables. I personally wouldn't normally recommend that anyway. If you could clarify what specifically you are trying to make, it could be possible to give more targeted advice.
