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

Since R2020b

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.

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

collapse all

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

collapse all

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

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.
