C 서비스 인터페이스
R2022b 이후
C 서비스 코드 인터페이스 구성을 사용하는 컴포넌트 모델에서 코드를 생성하는 경우, 모델 데이터 요소를 서비스 인터페이스에 매핑합니다. 서비스 인터페이스는 타깃 플랫폼 서비스의 요구대로 생성 코드에 대한 함수 프로토타입 정보와 데이터 통신 방법(직접 액세스, 실행 중이 아닐 때 또는 실행 중일 때)을 지정합니다. 코드 생성기는 서비스 인터페이스 코드를 생성할 때 제약 조건을 적용하여 특정 타깃 환경에서 사용할 코드를 더 쉽게 통합할 수 있도록 해 줍니다. 매핑에 사용할 수 있는 서비스 인터페이스 목록은 모델에 연결된 공유 Embedded Coder 사전에 정의되어 있는 인터페이스에 따라 결정됩니다. 사전 디폴트 서비스 인터페이스가 타깃 플랫폼 서비스 요구 사항과 일치하는 경우 매핑을 변경할 필요가 없으며 컴포넌트 인터페이스 코드 생성 및 검토를 건너뛸 수 있습니다.

데이터 액세스 및 초기화
- Reuse Parameter Data in Different Data Type Contexts
Reuse parameter data by creating aSimulink.Parameterobject or numeric MATLAB® variable that you can use in different data type contexts. - Limitations for Block Parameter Tunability in Generated Code
Limitations can prevent a block parameter from appearing in the generated code as tunable, which means you cannot interact with the parameter value after compiling the code. - Access Signal, State, and Parameter Data During Execution
As you iteratively develop a model, capture output signal and state data that model execution generates. Tune parameter values during execution to observe results on the outputs. - Switch Between Sets of Parameter Values During Simulation and Code Execution
Switch between independent sets of values for the same block parameters by storing the sets in an array of structures. - Configure Packaging of Parameter Arguments in Generated Code
Customize the implementation of parameter arguments in generated code. - Control Signal and State Initialization in the Generated Code
Generate code that enables you to store tunable initial conditions in memory, for example, for modeling a system that shuts down and restarts. - Initialization of Signal, State, and Parameter Data in the Generated Code
To match the numerics of a simulation in Simulink®, the generated code assigns initial values to global data, especially for block states and parameters. - Compile Code Conditionally for All Values of Variant Parameters with Same and Different Dimensions
This example shows how to generate a C code that contains all the active and inactive values of variant parameters.
