DAQ with octave (open-source Matlab)

[Nico_Sag]

Hello,

I'm interested in reading data (generated by an accelerometer) from an Data Aquisitiebox from National Instruments (NI9234), which is connected with an USB connection.

But instead of using Matlab or an other software program, I would like to use some freeware like OCTAVE.

Is there someone who knows if it is possible, or how to read the data from the NI9234 with Octave?

I already tried to do this in the same way like you have to do it in Matlab, but it didn't work...

I don't know if National Instruments supports software like Octave to read the data?

Thanks in advance,

Nico.

Hello Nico,

NI does not support Octave directly. Your device comes with the DAQmx driver which contains DLL functions to be able to use it and get data from it. That is probably how you did it in Matlab? As far as I know in Octave there is no support for calling DLL's but there is a possibility via so called OCT files. I found some info about that on the following page.

I think that would be about your only option to this. Unfortunately I cannot give you any guarantee that it will work though.

Hope this helps,

Regards,
