setDataStore

Configure local or shared local data store for code generation

    Description

    example

    setDataStore(myCodeMappingObj,dataStore,Name,Value) configures the specified local or shared local data store for code generation. Use this function to map a local or shared local data store to the storage class and storage class property settings that the code generator uses to produce C code for that data store.

    Examples

    In the model code mappings for model myConfigModel, set the storage class for local data store mode to ExportedGlobal.

    cm = coder.mapping.api.get('myConfigModel');
    setDataStore(cm,'mode','StorageClass','ExportedGlobal');
    

    In the model code mappings for model myConfigModel, set the storage class for local and shared local data stores throughout the model to Model default.

    cm = coder.mapping.api.get('myConfigModel');
    dsmHandles = find(cm,'DataStores')
    setDataStores(cm,dsmHandles,'StorageClass','Model default');
    

    In the model code mappings, for model myConfigModel, set the code identifier for local data store mode to ds_mode.

    cm = coder.mapping.api.get('myConfigModel');
    setDataStore(cm,'mode','Identifier','ds_mode');
    

    Input Arguments

    collapse all

    Code mapping object (model code mappings) returned by a call to function coder.mapping.api.get.

    Example: myCM

    Path of the Data Store Memory block for which to return the code mapping information, specified as a character vector or string scalar. Alternatively, you can specify a block handle or the name of the data store. If you specify the name of a data store and that name is not unique within the model, Simulink® returns an error that instructs you to specify the block path or handle. To specify multiple data stores, use an array.

    Example: blockHandle

    Data Types: char | string | block_handle | array

    Name-Value Pair Arguments

    Example: 'StorageClass' 'ExportedGlobal'

    Specify comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments as Name1,Value1,…,NameN,ValueN. The order of the name and value pair arguments does not matter.

    Storage class to set for the specified data store. The name of a predefined storage class or storage class that is defined in the Embedded Coder Dictionary associated with the model. See Configure Data Stores for C Code Generation.

    Name for the variable that represents the local data store in the generated code.

    Data Types: char | string
