Model Configuration Raspberry Pi Blockset

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.
