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

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");
