Uhr / JalousiensteuerugDie Seite wird bald aktualisiert. Ich habe meine alte Hardware aus 2006 mit aktueller Technologie teilweise ersetzt. Mit einem Raspberry PI und Teenys++ 2.0. Details und Source Codes kommen bald.
2017Alte Platinen aus 2006, mit Atmel ATmega16 Die blaue Plop Uhr (aus dem Jahr 2006)BeschreibungDiese Uhr stellt die Uhrzeit mit blauen Leuchtdioden dar. Die Zeit wird vom Netzwerk bezogen. Weiters ist ein Relais angeschlossen um den Strom bei einer Steckdose via Netzwerk ein/aus zu schalten (z.B. Lampe ein/ausschalten).
Wozu das ganze? Ich wollte eine Uhr die blau leuchtet. Realisiert wurde die Uhr mittels Atmel Prozessor, dem Wilke EM01-ETH-S Netzwerkmodul und DotMatrix Displays. Programmiert in Assembler. Demnächst werden auch Jalousien via Netzwerk bedient werden können. Jedoch müssen vorher noch andere Sachen programmiert und fertiggestellt werden. Foto/Video
Video Wilke EM-01 Netzwerk RoutinenFür alle, die das Netzwerkmodul EM-01 von Wilke mit dem Atmel Prozessor ATMEGA16 ansteuern wollen stelle ich ein Besipielprogramm in Assembler unter der GPLv2 Lizenz zur Verfügung. Es wird ein ATMEL ATMEGA16 mit 4Mhz Taktung verwendet. Der Prozessor ist mittels serieller Schnittstelle (19200 Baud) verbunden. Die Steuerleitungen des EM-01 werden mittels PORTC angesprochen.
Es kann mittels telnet eine Verbindung aufgebaut werden. Hinweis: Es wird kein default Gateway gesetzt. daher funktioniert das Programm nur im lokalen Netzwerk.
