How to transform a data array into a waveform using LabWIndows/CVI

[martiemp]

Dear All,

I would like to transform a data array into a waveform using LabWIndows/CVI.

I tried to use the function _CreateArbWaveform but I didn’t succeed; I got a compile error “Missing prototype” (Function declaration or call is for a function without prototype declaration information). Does anybody know how to convert a data array into a waveform?

Thank you very much for your help.

Best Regards,

Martiemp

What exactly do you mean by waveform? Where are you intending to use such data type?

Hi martiemp, 

Your problem (the compilation error) is not about creating waveforms, it is possibly about including the correct header file for the function (_CreateArbWaveform) you are going to use.

Your utilisation of the function call may be perfect, but the compiler have to "see" the function's prototype before it can compile your code.

Where does that function come from? From another file you wrote or an off-the-shelf library?
