MATLAB: A good way to publish simulink values to GUI from a running model

guiguidesimulationsimulink

I currently can affect a running model from my GUI, both start/pause/stop and update values that are inputs to the current model. I do this via workspace variables to constant blocks using set_param(…’update’).
Now I need to show values from my running model in my GUI but I’m not sure of how I would do that? My plan was to use a 1 second timer and then read out signal values but I’m not sure of how to do that. Please let me know if you have a good way!!
Any thoughts are appreciated, thanks! //bjoern

  • This is a good approach.
    However with just that, your GUI will need a mechanism to poke at the model to get the data.
    I would combine that with an event listener:
    That way, the event listener can send the data from the runtime object to your GUI automatically every time the block output value is updated.
