Simulink Model

To bring the DigitalRead system object into Simulink®, follow the steps:

  1. Create a new Simulink model.

  2. Add the MATLAB System block from the User-Defined Functions library.

  3. In the block, set System object name to DigitalRead.

  4. From the Sinks library, add a Scope block to the model.

  5. In the Simulink Editor from the Simulation tab, select Prepare > Model Settings.

  6. In the Configuration Parameters dialog box, on the Hardware Implementation pane, set Hardware board to match your hardware, for example, 'Arduino Due'.

  7. In the model toolbar, change the Simulation stop time to Inf.

  8. To build and run the model containing your System object™ on the hardware board, select Monitor & Tune > Run.
