Gerätetreiber-Blöcke

Erstellen eines Gerätetreiber-Blocks, um auf bestimmte Funktionen der Hardwareplatine zuzugreifen

Ein Gerätetreiber-Block ist eine spezielle Form des MATLAB System-Blocks, der benutzerdefinierten C/C++ Gerätetreibercode generiert, wenn er auf einer Arduino^®-Hardwareplatine bereitgestellt wird. Gerätetreiber-Blöcke bieten einfachen Zugriff auf Hardwareplatinen-Funktionen wie Kommunikationsprotokolle oder Hardware-Bibliotheken, die nicht im Simulink^®-Supportpaket für Arduino-Hardware enthalten sind.

Sie können einen Gerätetreiber-Block aus einer System object™-Vorlage entwickeln und den resultierenden Block mit anderen Benutzern teilen.
