setDataStore
Configure local or shared local data store for code and calibration file (a2l) generation
Since R2020b
Description
setDataStore(
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.myCodeMappingObj

Examples
Configure Storage Class for Local Data Store
In the model code mappings for model
ConfigurationRapidPrototypingInterface
, set the storage class for
local data store mode
to ExportedGlobal
.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); setDataStore(cm,"mode",StorageClass="ExportedGlobal");
Configure Storage Class for Local and Shared Local Data Stores in Model to Model default
In the model code mappings for model
ConfigurationRapidPrototypingInterface
, 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");
Configure Code Identifier for Local Data Store
In the model code mappings, for model
ConfigurationRapidPrototypingInterface
, 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");
Configure Calibration Properties for Local Data Store
From the model code mappings for model
ConfigurationRapidPrototypingInterface
, 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
myCodeMappingObj
— Code mapping object
CodeMapping
object
Code mapping object (model code mappings) returned by a call to function
coder.mapping.api.get
.
Example: myCM
dataStore
— Block path, block handle, or name of data store
character vector | string scalar | block handle | array of character vectors | array of string scalars | array of block handles
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 as
Name1=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

.
Data Types: char
| string
PreserveDimensions
— Boolean flag indicating whether to preserve dimensions of multidimensional arrays
True
| False
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
,
GetSet
, ImportFromFile
,
Localizable
, and Volatile
.
Data Types: logical
SetFunction
— Name of set function
character string | string scalar
Name of a set
function that a data element calls in the
generated code. Applies to storage class GetSet
.
Data Types: char

StructName
— Name of structure
character vector | string scalar
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
storageClassPropertyName
— Value of storage class property
depends on property definition
Storage class property defined in the Embedded Coder Dictionary. Values that you can specify vary depending on the storage class definition.
Export

true
(default) | false
Enable this property to generate the data store to calibration file (a2l).
BitMask
— Extract single bits from the data store value

Name of the method for converting the ECU-internal value to a physical value for easy readability.
Data Types: char
| string
DisplayIdentifier
— Display name of the data store

MeasurementService
— Name of measurement service interface
Dictionary default
(default) | character vector | string scalar
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.
