Integrazione del codice C/C++ utilizzando lo strumento del codice legacy
È possibile integrare le funzioni C (o C++) esistenti, come i driver del dispositivo, le tabelle di ricerca e le funzioni e interfacce generali, nei modelli di Simulink® utilizzando lo strumento del codice legacy. Utilizzare lo strumento del codice legacy per specificare il nome della S-function, i file e il percorso necessari per la compilazione e le opzioni per la S-function generata.
Utilizzare la funzione legacy_code per generare una S-function, compilare e collegare la S-function generata e creare una maschera per richiamare la S-function generata.
Prima di utilizzare legacy_code, assicurarsi che sia impostato un compiler C per l’installazione di MATLAB®.
