addSignal

Add block output signal to model code mappings

    Description

    example

    addSignal(myCodeMappingObj,portHandle) adds signals specified by the block output port handles to the specified model code mappings.

    This function does not apply to signals that originate from root-level Inport blocks.

    example

    addSignal(myCodeMappingObj,portHandle,Name,Value) adds signals specified by the block output port handles to the model code mappings. It configures the storage class and values of storage class properties that the code generator uses to produce C code for the signal data.

    Examples

    For model myConfigModel, add the output signals of lookup table blocks Table1D and Table2D to the model code mappings. After creating the object cm by calling function coder.mapping.api.get, get handles to the output ports for lookup table blocks. Add the output signals to the code mappings with a call to addSignal.

    cm = coder.mapping.api.get('myConfigModel');
    lut1D_ports = get_param('myConfigModel/Table1D','PortHandles');
    lut2D_ports = get_param('myConfigModel/Table2D','PortHandles');
    lut1D_outPort = lut1D_ports.Outport;
    lut2D_outPort = lut2D_ports.Outport;
    addSignal(cm,[lut1D_outPort,lut2D_outPort]);
    

    For model myConfigModel, add the output signals of lookup table blocks Table1D and Table2D to the model code mappings. After creating the object cm by calling function coder.mapping.api.get, get handles to the output ports for lookup table blocks. Add the output signals to the code mappings and set the storage class for the signals to ExportedGlobal with a call to addSignal.

    cm = coder.mapping.api.get('myConfigModel');
    lut1D_ports = get_param('myConfigModel/Table1D','PortHandles');
    lut2D_ports = get_param('myConfigModel/Table2D','PortHandles');
    lut1D_outPort = lut1D_ports.Outport;
    lut2D_outPort = lut2D_ports.Outport;
    addSignal(cm,[lut1D_outPort,lut2D_outPort],'StorageClass','ExportedGlobal');
    

    Input Arguments

    collapse all

    Code mapping object (model code mappings) returned by a call to function coder.mapping.api.get.

    Example: myCM

    Signal to add to the code mappings, specified as a handle of an output port of the source block of the signal. To specify multiple port handles, use an array.

    Example: portHandle

    Data Types: port_handle | array

    Name-Value Pair 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.

    Storage class to set for the specified signals. The name of a predefined storage class or a storage class that is defined in the Embedded Coder Dictionary associated with the model. See Configure Signal Data for C Code Generation

    Name for the variable that represents the signal data in the generated code.

    Data Types: char | string
