Your VIs here need some other necessary parts, but you don't give. We can't open these VIs successfully. mcniko311, You should know the maximal sampling rate of your system and what is the number of FIFO' s bytes. you need make sure that an overflow doesn't happen. Lodestar

Good. I have never paid attention before.

You have hardwares, and you have LabVIEW. That means you can do anything.

Hi Ton, To directly use a user-defined function in the command window of LabVIEW mathscript, for example Add(x,y), someone should make sure he has configured the path of the default folder in which there is your function, namely the .m file with the same name . The reason I can't use my .m file is that after setting the path of .m file searching folder I don't restart Labview. This is because the setting become effect, we have to restart LabVIEW. My solution. Thanks confidence

Thanks for your attention, I have solved it.

Hi, everybody. I wanna call a .m-file in labview mathscript window. the m-file likes this: %m-file function result=add(a,b) result=a+b; %end when I input "add(1,3)" in command window, but the command window shows "Unknown symbol on line 1: add". How to call a m file which includes the function made by myself? ps: don't use mathscript node, and don't copy the content of the function and paste it into command window. thanks for your help

It maybe need you to install necessary module .

Ton, Thank you very much. I can change LV program to C/C++ code using microprosser SDK now. The variation reason is that I need to write a special instruction with C/C++ code.

Hi, how to change VI to C/C++ code? thanks

If you weren't femiliar with it, you can't understand somebody's suggestion. you need to configure baud rate, buffer size and so on, and have to clearly know what's the command the microcontroller response.

QUOTE (khokhar @ Apr 13 2009, 03:28 PM) it's easy if you only want to call external software in the labview and save the data by itself. you can use Calling System Exec VI.
