Interfacce di servizio C
Da R2022b
Quando si genera codice da un modello dei componenti che utilizza una configurazione dell'interfaccia del codice di servizio C, è necessario mappare gli elementi dati del modello alle interfacce di servizio. Un'interfaccia di servizio specifica le informazioni relative al prototipo della funzione e il metodo di comunicazione dei dati (accesso diretto, al di fuori dell'esecuzione o durante l'esecuzione) per il codice generato, in base a quanto richiesto dai servizi della piattaforma di destinazione. Il generatore di codice applica vincoli durante la produzione del codice dell'interfaccia di servizio, in modo da facilitare l'integrazione del codice per l'utilizzo in un ambiente di destinazione specifico. L'elenco delle interfacce di servizio disponibili per la mappatura è determinato dalle interfacce definite nel dizionario condiviso Embedded Coder associato al modello. Se le interfacce di servizio predefinite del dizionario sono in linea con i requisiti di servizio della piattaforma di destinazione, non è necessario apportare modifiche alla mappatura ed è possibile passare direttamente alla generazione e alla revisione del codice dell'interfaccia del componente.

Accesso ai dati e inizializzazione
- 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.
