Model Configuration Simulink Coder Support Package for STMicroelectronics Nucleo Boards

Hardware Implementation Pane Overview

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 one of the Nucleo boards, for eg.STM32 Nucleo F302R8.

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.

Note

In the Configuration Parameter dialog box, go to Code Generation > Interface > Code interface and ensure Code interface packaging is set to Nonreusable function.

For more information on selecting a hardware support package and general configuration settings, see Hardware Implementation Pane.
