Unable to detect AD2 on MATLAB

[spbhanus]

Hello All,
I have purchased AD2 and I tested it using the Waveforms Software and got live inputs/outputs, works great.

However, I cannot detect the device in MATLAB using the command 

daqlist("digilent")

After using this command I am getting no output. (attached in the image)

 

I am referring to this tutorial Getting started

Please let me know how can I start using the Device on MATLAB.

Hi @spbhanus,

I don't have MATLAB installed nor a license for it, but looking at some of these MathWorks pages, you should be able to check what toolbox you have installed via the `ver` command, be able to confirm which vendors have support in your toolbox via `daqvendorlist` and which devices are attached via `daqlist`. Here are the MathWorks pages I was referencing: link1, link2. In case it turns out that you don't have the hardware support package for the Digilent hardware, there are some instructions on how to install it on this Mathworks page.

As Attila mentioned on your other thread, not all functionalities are inherently supported in the Matlab toolbox; some of those limitations are explained on this Mathworks page.

Thanks,
JColvin

I just installed the Hardware support package.

I get this when I do "ver"

This is for the daqvendorlist

    "digilent"    {'Digilent Inc.'  }    "4.4 (R2021b)"      "3.7.20" 

This is when I run daqlist("digilent")

>> daqlist("digilent")

ans =

  0×0 empty table

Please let me know how can I make this work

Hi @spbhanus

Please contact Mathworks.
It is working for me with MATLAB 2020b

It prints error if the device is used by another application or the WF runtime version is not 3.7.2(0)

[spbhanus]

It is working now! thanks for assistance.

Hi @spbhanus

May I ask what the problem was.

[spbhanus]

I tried a couple of things, installing the support package for Digilent devices, Downgraded the Waveforms software to whichever versions the support package was installing, use MATLAB 2021b, tried other USB ports, closing the Waveforms software before running the MATLAB code. It could be one of these things, some of these things or maybe all.

Thanks for your assistance.
