Data Exchange Interfaces

Set up interfaces for exchanging data

Set up and use techniques and capabilities for exchanging data between generated and external application code.

Data interfaces are available for exchanging data between generated and external code or data. Use the C API to write code that interacts with generated code. Export an ASAP2 file for a measurement, calibration, and diagnostic system.

To log data to a MAT-file during execution of generated code, see Log Program Execution Results.

Functions

addCoderXCPInfoCreate ASAP2 file with IF_DATA XCP block that describes the Simulink Coder XCP slave configuration
rtw.asap2MergeMdlRefsGenerate single A2L file for model by merging A2L files generated for top model and referenced models
rtw.asap2SetAddressSet ECU address in A2L file

Topics

C API Interface to Model Data

Exchange Data Between Generated and External Code Using C API

Write host-based or target-based application code that interacts with generated model code.

Use C API to Access Model Signals and States

Write application code to interact with model signals and states.

Use C API to Access Model Parameters

Write application code to interact with model parameters.

ASAP2 File Generation

Export ASAP2 File for Data Measurement and Calibration

Configure model for ASAP2 file generation.

Calibrate Generated Code and Monitor Signals Through XCP and Third-Party Tools

Generate XCP external mode target application and ASAP2 file that describes XCP slave configuration.

Customize Generated ASAP2 File

Edit Target Language Compiler (TLC) files to customize the ASAP2 file generated from a Simulink® model.

Parameter Tunability and Signal Visibility

Create Tunable Calibration Parameter in the Generated Code

In the generated code, create tunable parameter data that you can access during rapid prototyping and calibration.

C Code Generation Configuration for Model Interface Elements

Control the representation of model data elements and functions in generated C code.
