DAQ Analog Output using Matlab Script

[Charls31416]

 Hello everyone

I'm trying to generate an analog output with a DAQ USB-6008, generating some unusually waveform  using a matlab script but i get some troubles, (i'm also reading  the  signal with an Analog input of the same DAQ)  i can't write the waveform to the output of the DAQ. First I try using a "simulate signal VI" and everyting was right, but when a tried to write the values of 1D array generated in the script it doesn't work. I'm learnig Labview since yesterday and i realy need some help 😕  Thanks

Why would you be using Matlab?

In any case, you can't write a waveform or an array to the 6008. As had been discussed numerous times, you can only write a single point at a time because the 6008 only has software timed analog output. You would have to place the DAQmx Write inside a for loop that auto-indexes the array. Timing is achieved with a wait function. The timing is going to be slow and subject to considerable jitter due to Windows.
