Description

Create a function object to define function description and export it to an ASAP2 file.

Creation

userFunction = coder.asap2.Function creates a function object. You can use the object to define new function description and export it to an ASAP2 file.

Properties

expand all

Specify a name for the function.

Example: "CustomFunction_1"

Specify comments and description for the custom function.

Example: "Description of the function"

Specify the version for the custom function.

Example: "Custom_Function_version"

Set of notes represented as multi-line ASCII description texts.

Example: "Custom_Function_Annotation"

Specify array of input measurements.

Example: ["measurement1","measurement2"]

Specify array of output measurements.

Example: ["measurement1","measurement2"]

Specify array of local measurements.

Example: ["measurement1","measurement2"]

Specify array of defined characteristics.

Example: ["characteristic1","characteristic2"]

Specify array of referenced characteristics.

Example: ["characteristic1","characteristic2"]

Create ECU Description Object

Open a model, build, and create ECU description object.

open_system("ASAP2Demo")
slbuild("ASAP2Demo")
### Searching for referenced models in model 'ASAP2Demo'.
### Total of 2 models to build.
### Starting serial code generation build.
### Successfully updated the model reference code generation target for: ASAP2DemoModelRef
### Starting build procedure for: ASAP2Demo
codeInterfacePackaging: Nonreusable function

Create Custom Function

Create a function object template and add the necessary fields. 

userFunction = coder.asap2.Function
userFunction = 
  Function with properties:

                  Name: "undefined"
       FunctionVersion: [1×0 char]
        LongIdentifier: [1×0 char]
            Annotation: [1×0 char]
        InMeasurements: [1×0 string]
       OutMeasurements: [1×0 string]
       LocMeasurements: [1×0 string]
    DefCharacteristics: [1×0 string]
    RefCharacteristics: [1×0 string]
          SubFunctions: [1×0 string]


userFunction.Name = 'Custom_Function1'
userFunction = 
  Function with properties:

                  Name: 'Custom_Function1'
       FunctionVersion: [1×0 char]
        LongIdentifier: [1×0 char]
            Annotation: [1×0 char]
        InMeasurements: [1×0 string]
       OutMeasurements: [1×0 string]
       LocMeasurements: [1×0 string]
    DefCharacteristics: [1×0 string]
    RefCharacteristics: [1×0 string]
          SubFunctions: [1×0 string]


userFunction.LongIdentifier = 'Custom Function by user'
userFunction = 
  Function with properties:

                  Name: 'Custom_Function1'
       FunctionVersion: [1×0 char]
        LongIdentifier: 'Custom Function by user'
            Annotation: [1×0 char]
        InMeasurements: [1×0 string]
       OutMeasurements: [1×0 string]
       LocMeasurements: [1×0 string]
    DefCharacteristics: [1×0 string]
    RefCharacteristics: [1×0 string]
          SubFunctions: [1×0 string]

Export the Function to ASAP2 File

Add the function to ECU description object and generate ASAP2 file using the description object.

add(descObj,userFunction)
coder.asap2.export("ASAP2Demo",CustomEcuDescriptions=descObj)
Following Characteristics or Measurements with unsupported data types are not exported in ASAP2 file. "ASAP2Demo_DW.ASAP2DemoModelRef_InstanceData"
