Connecting an Instrument using icdevice

Hi all,

I'm and trying to connect a working device PicoScope 2405A,3405D MSO,4824A and 5444D to Matlab R2024b on Windows 11.

I have successfully downloaded PicoSDK_64_11.1.0.418 and the PicoScope Series A API MATLAB Generic Instrument Driver for these instruments, and added the file paths to MATLAB. The file address of the SDK is 'C:\Program Files\Pico Technology\SDK', and the file address of the Generic Instrument Driver is 'D:\MATLAB\MATLAB\PicoSupport'.

The contents of the SDK folder are:

As an example, the contents of the extension folder for the 3000 series are（The address of this folder is'D:\MATLAB\MATLAB\PicoSupport\ps3000a\win64'）:

There is an issue that the 'ps3000a.dll' file has two addresses ('d:\MATLAB\MATLAB\PicoSupport\ps3000a\win64' and 'C:\Program Files\Pico Technology\SDK\lib'), as both folders contain this file simultaneously.

But, when trying to run PS3000A_ID_Block_Example.m script, which is an example script given by Pico, I get the following error messege:

PicoScope 3000 Series MATLAB Instrument Driver

Error using PS3000A_ID_Block_Example (line 71)

Operation failed: An error occurred while executing the driver disconnect code.

Indexing with a dot is not supported for variables of this type.

If this error is not an instrument error, use MIDEDIT to inspect the driver.

The line failing is:

    ps3000aDeviceObj = icdevice('picotech_ps3000a_generic.mdd', '');

Any help would be appreciated,

Many thanks!

Have you got the PicoScope Support Toolbox addon as well as the instrument drivers for the specific series?

Also I don't think the dll file should be in the folder with the files for the examples and it isn't a part of the files on the github repository for the PicoScope 3000 Series A API MATLAB Generic Instrument Driver.
