Gerätetreiber-Blöcke
Ein Gerätetreiberblock ist eine spezialisierte Form des MATLAB®-Systemblocks, der benutzerdefinierten C/C++-Gerätetreibercode generiert, wenn er auf einem Arduino®-Hardwareboard bereitgestellt wird. Gerätetreiberblöcke bieten einfachen Zugriff auf Hardware-Board-Funktionen wie Kommunikationsprotokolle oder Hardware-Bibliotheken, auf die Sie mit Funktionen und Blöcken im Simulink® Support Package für Arduino-Hardware nicht zugreifen können.
Sie können einen Gerätetreiber-Block aus einer System object™-Vorlage entwickeln und den resultierenden Block mit anderen Benutzern teilen.
