setDataStore

Configure local or shared local data store for code and calibration file (a2l) generation

    Description

    example

    setDataStore(myCodeMappingObj,dataStore,Name,Value) configures the specified local or shared local data store for code and calibration file (a2l) 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. Or, set the calibration access for that data store.

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

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

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

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

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

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

    From the model code mappings for model rtwdemo_configrpinterface, set the calibration properties configured for the local data store mode.

    open_system('rtwdemo_configrpinterface');
    cm = coder.mapping.api.get('rtwdemo_configrpinterface');
    setDataStore(cm,mode,'Export',true);
    setDataStore(cm,mode,'CalibrationAccess','Calibration');
    setDataStore(cm,mode,'CompuMethod','CM_state');
    setDataStore(cm,mode,'DisplayIdentifier','state_X');
    setDataStore(cm,mode,'Format','%4.2');
    

    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 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

    File name for a C source file that contains definitions for global data read by data elements and external code. Applies to storage classes ExportToFile and Volatile.

    Data Types: char | string

    Name of a get function that a data element calls in the generated code. Applies to storage class GetSet.

    Data Types: char | string

    File name for a C header file that contains declarations for global data read by data elements and external code. Applies to storage classes ExportToFile, GetSet, ImportFromFile, and Volatile.

    Data Types: char | string

    Name of the model that owns global data that is used by other models in the same model hierarchy. The code generated for the model that owns the data includes the global data definition. Applies to storage classes ExportToFile and Volatile.

    Data Types: char | string

    When model configuration parameter Array layout is set to Row-major, a flag that indicates whether to preserve dimensions of a data element represented in generated code as a multidimensional array. Applies to storage classes ExportToFile, ImportFromFile, Localizable, and Volatile.

    Data Types: logical

    Name of a set function that a data element calls in the generated code. Applies to storage class GetSet.

    Data Types: char | string

    Name that the code generator uses to identify the structure for a data element in the generated code. Applies to storage classes Bitfield and Struct.

    Data Types: char | string

    Storage class property defined in the Embedded Coder Dictionary. Values that you can specify vary depending on the storage class definition.

    Enable this property to generate the data store to calibration file (a2l).

    Mask value in hexadecimal format to extract single bits from the data store during calibration. This property is applicable only for integers.

    Data Types: hexadecimal

    Select Calibration for the data store to enable the calibration. Select NoCalibration to view the value of the data store and disable the calibration.

    Name of the method for converting the ECU-internal value to a physical value for easy readability.

    Data Types: char | string

    Optional display name of the data store for the measurement purpose in the calibration tool, which is different than the data store name in the Simulink model.

    Data Types: char | string

    Special display format to be specified for measurement in the calibration tool. This format specification overrules the display format specified in CompuMethod of the data store.
