Syntax
Description
setDataStore([myCodeMappingObj](#mw%5F8d114784-e201-4049-9782-749a923fa338),[dataStore](#mw%5F8db1ed74-6996-4459-95dc-7dfa83343954),[Name,Value](#namevaluepairarguments)) 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.
Examples
In the model code mappings for modelConfigurationRapidPrototypingInterface, set the storage class for local data store mode to ExportedGlobal.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); setDataStore(cm,"mode",StorageClass="ExportedGlobal");
In the model code mappings for modelConfigurationRapidPrototypingInterface, set the storage class for local and shared local data stores throughout the model to Model default.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); dsmHandles = find(cm,"DataStores") setDataStore(cm,dsmHandles,StorageClass="Model default");
In the model code mappings, for modelConfigurationRapidPrototypingInterface, set the code identifier for local data store mode to ds_mode.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); setDataStore(cm,"mode",Identifier="ds_mode");
From the model code mappings for modelConfigurationRapidPrototypingInterface, set the calibration properties configured for the local data store mode.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); 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
Code mapping object (model code mappings) returned by a call to functioncoder.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
Specify optional pairs of arguments asName1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.
Before R2021a, use commas to separate each name and value, and enclose Name in quotes.
Example: StorageClass="ExportedGlobal
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 classesExportToFile 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 classesExportToFile, 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 andVolatile.
Data Types: char | string
When model configuration parameter Array layout is set toRow-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,GetSet, 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 andStruct.
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 inCompuMethod of the data store.
String or character vector containing the name of a measurement service interface defined in the Embedded Coder Dictionary. By configuring the measurement service interface for signals, states, and data stores, you can preserve the data in the generated code for measurement. To use the dictionary default, specify"Dictionary default". If data from the state does not need to be preserved in the code, specify "Not measured".
To configure the measurement service interface, you must attach an Embedded Coder Dictionary that defines a service interface configuration to the model. For more information, see Configure Measurement Service Interfaces for Signals, States, and Data Stores.
