Model Configuration Parameters for BBC micro:bit

Hardware Implementation Pane Overview

Default Hardware Implementation Pane

Configure hardware board to run Simulink^® models.

1. In the Simulink Editor, select Simulation > Model Configuration Parameters.

2. In the Configuration Parameter dialog box, click Hardware Implementation.

3. Set the Hardware board parameter to BBC micro:bit.

4. The parameter values under Hardware board settings are automatically populated to their default values.

   You can optionally adjust these parameters for your particular use case.

5. Click Apply to apply the changes.
