Hi everyone,

I am interfacing my beaglebone platform with simulink for a real time application. I take data from a sensor and I want to store its values when I send a command by a UDP communication.

I know that there are "to workspace" or "to file" blocks but they save all the date from the beginning of the simulation.

Therefore, I am trying to use fopen, fprintf, fclose in an embedded matlab function, but it does not work because, even if it compiles, it does not save any file.

Do you know how can I save data?

Flavio

You're trying to save data on the MATLAB side, and not standalone on the BeagleBone, correct? If so, you can try this out.

Replace the "To Workspace" block with a regular output port (Out1) block
Go to Simulation > Model Configuration Parameters, in the Data Import/Export pane
Make sure the Output option is enabled
Enable the Limit data points to last option and set it to 1
