How do I use Simulink Coder to build a Simulink model and generate the necessary header files that seem to be missing?

Hello,

I’m trying to build a simple LQR block diagram using Simulink Coder for deployment on a Raspberry Pi board.

However, during the build process, I encounter an error stating that files like MW_raspi_init.h, MW_Pyserver_control.h, and linuxinitialize.h cannot be found.

How can I resolve this issue?

Hello @준호,

I understand that you are facing an issue during code generation using Simulink Coder for Raspberry Pi, where errors such as missing files "MW_raspi_init.h", "MW_Pyserver_control.h", and "linuxinitialize.h" are being reported.

These header files are essential components of the Simulink Support Package for Raspberry Pi Hardware provided by MathWorks. This issue usually occurs when the support package is either not installed or not configured properly.

To resolve this issue, please follow the steps below:

1. Install the Raspberry Pi Support Package:

Ensure that the Simulink Support Package for Raspberry Pi Hardware is installed.

• Open MATLAB.
• Navigate to Home > Add-Ons > Get Hardware Support Packages.
• Search for “Simulink Support Package for Raspberry Pi Hardware” and install it.

2. Set Up the Support Package:

MathWorks-supported hardware boards and devices require additional configuration steps to connect properly with MATLAB and Simulink. Each support package includes a hardware setup process that guides you through registering, configuring, and connecting to your hardware board.

If you have already installed the support package, you can launch the setup as follows:

• Open the Add-Ons panel in MATLAB.
• Click the Options button next to the installed Raspberry Pi support package.
• Select Setup to begin the hardware setup process.

The Hardware Setup window will then guide you step by step through the necessary configuration to get your board ready. Simply follow the instructions on each page.

Once the setup is complete, you can open example models to explore the features and get started quickly.

For more details, please refer to the official documentation:

3. Configure Simulink Model for Code Generation:

To configure the model for Raspberry Pi hardware:

a. Open the Modeling tab and press Ctrl+E to open Configuration Parameters dialog box.

b. Go to Hardware Implementation > Hardware board and select Raspberry Pi.

Kindly refer to this MathWorks documentation for more details:

Get Started with Simulink Support Package for Raspberry Pi Hardware: https://www.mathworks.com/help/simulink/supportpkg/raspberrypi_ref/getting-started-with-raspberry-pi-hardware.html

The missing header files should be found automatically during code generation after completing the steps above.

I hope this helps!
