setSignal
Configure block signal data for code and calibration file (a2l) generation
Since R2020b
Description
setSignal(
configures signals specified by block output ports for code and calibration file (a2l)
generation. Use this function to map specified block output ports to the storage class and
storage class property settings that the code generator uses to produce C code. Or, set the
calibration access for the corresponding signal data.myCodeMappingObj
,portHandle
,Name,Value
)
This function does not apply to signals that originate from root-level
Inport blocks. For signals that originate from root-level
Inport blocks, see setInport
.
Examples
Configure Storage Class for Block Output Signals
In the model code mappings for model
ConfigurationRapidPrototypingInterface
, set the storage class for
output signals of lookup table blocks Table1
and
Table2D
to ExportedGlobal
. After creating the
object cm
by calling function
coder.mapping.api.get
, get handles to the output ports for lookup
table blocks. Set the storage class for the output signals by calling
setSignal
.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); lut1_ports = get_param("ConfigurationRapidPrototypingInterface/Table1","PortHandles"); lut2_ports = get_param("ConfigurationRapidPrototypingInterface/Table2","PortHandles"); lut1_outPort = lut1_ports.Outport; lut2_outPort = lut2_ports.Outport; addSignal(cm,[lut1_outPort,lut2_outPort]); setSignal(cm,[lut1_outPort,lut2_outPort],StorageClass="ExportedGlobal");
Configure Storage Class for Signal Data in Model Code Mappings to Model default
In the model code mappings for model
ConfigurationRapidPrototypingInterface
, set the storage class for
block output signals to Model default
. After creating the object
cm
by calling function coder.mapping.api.get
,
get the port handles of the signal data in the code mappings. Set the storage class for
the signals by calling setSignal
.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); portHandles = find(cm,"Signals") setSignal(cm,portHandles,StorageClass="Model default");
Configure Code Identifiers for Block Output Signals
In the model code mappings for model
ConfigurationRapidPrototypingInterface
, set the code identifiers for
output signals of lookup table blocks Table1
and
Table2
to dout_Table1
and
dout_Table2
. After creating the object cm
by
calling function coder.mapping.api.get
, get handles to the output
ports for lookup table blocks. Set the code identifiers for the output signals by calling
setSignal
.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); lut1_ports = get_param("ConfigurationRapidPrototypingInterface/Table1","PortHandles"); lut2_ports = get_param("ConfigurationRapidPrototypingInterface/Table2","PortHandles"); lut1_outPort = lut1_ports.Outport; lut2_outPort = lut2_ports.Outport; addSignal(cm,[lut1_outPort,lut2_outPort]); setSignal(cm,lut1_outPort,Identifier="dout_Table1D"); setSignal(cm,lut2_outPort,Identifier="dout_Table2D");
Configure Calibration Properties for Signal
In the model code mappings for model
ConfigurationRapidPrototypingInterface
, configure the calibration
properties for signal Signal_1
.
openExample("ConfigurationRapidPrototypingInterface"); cm = coder.mapping.api.get("ConfigurationRapidPrototypingInterface"); lut1_ports = get_param("ConfigurationRapidPrototypingInterface/Table1","PortHandles"); lut1_outPort = lut1_ports.Outport; addSignal(cm,lut1_outPort); Signal_1 = find(cm,"Signal"); setSignal(cm,Signal_1,Export=true); setSignal(cm,Signal_1,CalibrationAccess="NoCalibration"); setSignal(cm,Signal_1,CompuMethod="CM_Signal_1"); setSignal(cm,Signal_1,DisplayIdentifier="Signal_display_name"); setSignal(cm,Signal_1,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
portHandle
— Output port handle of signal source block
port handle | array of port handles
Signal to add to the code mappings, specified as a handle of an output port of the signal's source block. To specify multiple port handles, use an array.
Example: portHandle
Data Types: port_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.
StorageClass
— Name of storage class
Auto
| Dictionary default
| ExportedGlobal
| ImportedExtern
| ImportedExternPointer
| Model default
Storage class to set for the specified signals. The name of a predefined storage class or storage class that is defined in the Embedded Coder Dictionary associated with the model. See Configure Signal Data for C Code Generation.
Identifier
— Name of variable
character vector | string scalar
Name for the variable that represents the signal data in the generated code.
Data Types: char
| string
Export
— Enable or disable generation of the signal to calibration file (a2l)
true
(default) | false
Enable this property to generate the signal to calibration file (a2l).
BitMask
— Extract single bits from the signal value
hexadecimal value
Mask value in hexadecimal format to extract single bits from the signal during calibration. This property is applicable only for integers.
Data Types: hexadecimal
CalibrationAccess
— Enable or disable calibration of the signal
NoCalibration
(default) | Calibration
Select Calibration
for the signal to enable the calibration.
Select NoCalibration
to view the value of the signal and disable
the calibration.
CompuMethod
— Name of conversion method
character vector | string scalar
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 signal
character vector | string scalar
Optional display name of the signal for the measurement purpose in the calibration tool, which is different than the signal name in the Simulink model.
Data Types: char
| string
Format
— Display format of the signal value
%[length].[layout]
Special display format to be specified for measurement in the calibration tool.
This format specification overrules the display format specified in
CompuMethod
of the signal.
