coder.mapping.api.CodeMapping

Model data and function interface configuration for C code generation

expand all in page

    Description

    A code mappings object and related functions enable you to configure C code generation for data of a Simulink model. For model data elements, code mappings associate data elements with configurations that consist of a storage class and storage class properties. Reduce the effort of preparing a model for C code generation by specifying default configurations for categories of data elements across a model. Override default configurations by configuring data elements individually. For smaller models, you can choose to configure each data element individually.

    Creation

    When you select a code generation app from the Apps tab in the Simulink® Editor, such as the Simulink Coder or Embedded Coder app, the app creates a coder.mapping.api.CodeMapping object if code mappings do not already exist. The app creates code mappings based on code customization settings stored in the model active configuration set object. The configuration set object can specify memory sections for data and functions.

    Create a coder.mapping.api.CodeMapping object programmatically by calling the function coder.mapping.utils.create.

    Examples

    collapse all

    For model myConfigModel, create the environment for configuring model data and functions for code generation. After calling this function, use calls to other functions listed under Object Functions to configure aspects of code generation for model interface elements.

    coder.mapping.utils.create('myConfigModel');
