Acquisition des données

[Fredo123Danzel]

Bonjour, 

j'aimerais savoir lorsqu'on fait ce genre d'acquisition des mesure comme ci-dessous, les données de mesures sont tous stockées dans une même case du tableau en sortie ou bien dans dans trois case différentes s'il vous plait ?

Hello,

I would like to know when we do this kind of measurement acquisition as below, the measurement data are all stored in the same box of the output table or in three different boxes please?

I don't see a "table with boxes" in your image, but I see a waveform array coming from DAQmxRead, displayed in the "data 2" indicator.

Each array element corresponds to a channel in your DAQmx task.

Why does the stop button in your image misses its label?

Salut, 

Oui j'ai une tache qui contient trois mesures. Est-ce-que les mesures sont logées de cette manière (Mesure A , mesure B et mesure C) comme en image ci-dessous svp?

You could use GoogleTranslate the same as I do - and you would do a favor for this worldwide forum, which is mainly using English. Otherwise there is a French regional board…

On your question:

When your channels are ordered as "channel A, channel B, channel C" in the DAQmx task then you get the same order in the waveform array!

Btw. it doesn't make (a lot of) sense to use a loop in your VI when you just use the reading of the last iteration…
