Model Configuration Simulink Support Package for Raspberry Pi Hardware

Hardware Implementation Overview

Configuration Parameters dialog box for Raspberry Pi hardware.

On the Modeling tab of the toolstrip, select Model Settings.
In the Configuration Parameter dialog box, select Hardware Implementation.
Set the Hardware board parameter to Raspberry Pi. This selection populates the Hardware board settings parameters with the default values for the Raspberry Pi^® hardware. You can adjust these parameters to suit your particular use case.
Click Apply.

Hardware Implementation pane parameters do not control hardware or compiler behavior. The parameters describe hardware and compiler properties for the MATLAB^® software.

Specifying hardware characteristics enables simulation of the model to detect error conditions that can arise when executing code, such as hardware overflow.
MATLAB uses the information to generate code for the platform that runs as efficiently as possible. MATLAB software also uses the information to give bit-true agreement for the results of integer and fixed-point operations in simulation and generated code.

Hardware board

Select the hardware board upon which to run your model.

Changing this parameter updates the dialog box display so that it displays parameters that are relevant to your hardware board.

To install support for a hardware board, start the Support Package Installer by selecting Get Hardware Support Packages. Alternatively, in the MATLAB Command Window, enter supportPackageInstaller.

After installing support for a hardware board, reopen the Configuration Parameters dialog box and select the hardware board.

Settings

Default: None if the specified system target file is ert.tlc, realtime.tlc, or autosar.tlc. Otherwise, the default is Determine by Code Generation system target file.

None: No hardware board is specified. The system target file specified for the model is ert.tlc, realtime.tlc, or autosar.tlc.
Determine by Code Generation system target file: Specifies that the system target file setting determines the hardware board.
Get Hardware Support Packages: Invokes the Support Package Installer. After you install a hardware support package, the list includes relevant hardware board names.
Hardware board name: Specifies the hardware board to use to implement the system this model represents.

Tips

When you select a hardware board, parameters for board settings appear in the dialog box display.
After you select a hardware board, you can select a device vendor and type.

Base rate task priority

This parameter sets the static priority of the base rate task. However, the changes that you make in this parameter do not result in any functionality differences on the Raspberry Pi hardware.

Settings

Default: 40

Detect task overruns

Detect when a task overrun occurs in a Simulink^® model running on the target hardware. Indicate when an overrun has occurred.

A task overrun occurs if the target hardware is still performing one instance of a task when the next instance of that task is scheduled to begin.

You can fix overruns by decreasing the frequency with which tasks are scheduled to run, and by reducing the number or complexity of the tasks defined by your model.

If those solutions do not fix the task overrun condition, and you are using External mode, consider disabling External mode.
