DLL Prototype fetch scope TestStand

[E.Boivin]

Hi,

I want to use the function "niScope_Fetch" from "niscope_32.dll" in order to manager Scope MultiRecord Acquisition in TestStand.

The Scope Board is initialized and configured witch IVI_Scope steps then with the "Specific Driver C Handle" I'm using "niScope_ConfigureMultiHorizontal" and now I want to pass parameters to "niScope_Fetch".

I have troubles with "double *wfm" prototype !

How should I pass pointer to 2D-Array of Double in TestStand ?

Is it necessary to change "double *wfm"

In fact, is is possible to use the following function directly with TestStand "C/C++ DLL" Adapter :

long niScope_Fetch(long vi, const char *channelList, double timeout, long numSamples, double *wfm, long *wfmInfo)

Do you have such an example or another way to read Scope MultiRecord acquisition without LabVIEW ?

Thanks in advance,

Emmanuel BOIVIN

Hello,

I do not really understand your question. Do you want to use a pointer to an 1D array of to a 2D array? The "double *wfm" prototype correspond to a pointer to an array of double. You can pass this kind of data in TestStand, I have done a small screenshot to show you:

The prototype to double pointer to a 2D array is like : double **ptr.

Do I answer your question?
