I wish to create an app that will connect to an SLRT target armed only with run-time knowledge of the target's IP, port, etc. This app will be compiled and will be running on a machine other than my normal host. Thus, the typical

tg = slrt('name');

construct won't work.

The old C-API included calls such as xpcOpenPort( ip, port ), but I can't find anything like that within the Matlab environment.

Thanks

In R2020b you can use any SSH client to connect to the target computer, install, load, start and stop a real-time application.

For more advanced instrumentation, MATLAB and Simulink Real-Time are required in the host computer (MATLAB Coder and Simulink Coder are no longer required if you don't need to modify/build the real-time application).

You can use the MATLAB API to build instrumentation with MATLAB App Designer:

If you need to work with external tools and languages, you can use MATLAB External Language Interfaces:

Hi Diego,

Thanks. But, I should have said that I'm using 2018b and will be for some time. I am using the App Designer and the App Compiler. I have several bits of heartburn associated with newer versions of SLRT (I've been talking with Sam Mirsky and others about that.) I plan to resist upgrading as long as possible.

Thus, back to my original question. Is there a Matlab analog to xpcOpenPort?

Thanks,

Jim B

Hi Jim, I would look at this example, specifically at the code behind the "Connect to Target" button:

I hope this helps.

Diego
