Integrar código C/C++ con la herramienta Legacy Code
Puede integrar las funciones de C (o C++) existentes, como los controladores de dispositivos, las tablas de búsqueda y las funciones e interfaces generales, en los modelos de Simulink® utilizando la herramienta Legacy Code. Utilice la herramienta Legacy Code para especificar el nombre de funciones S, la ruta y los archivos necesarios para la compilación, así como las opciones para la función S generada.
Utilice la función legacy_code para generar funciones S, compilarlas y vincularlas, y crear una máscara para llamarla.
Antes de poder utilizar legacy_code, asegúrese de que un compilador de C está configurado para su instalación de MATLAB®.
