| |
| == Hardware ==
| |
| * Raspberry Pi [http://www.gtkdb.de/index_36_2451.html seriell stumm geschalten]
| |
| * ioBoard [https://github.com/C3MA/uberschalter Projekt auf Github]
| |
| | |
| Das ioBoard wird über das UART des Raspberry Pis angesprochen.
| |
| Die Kommunikation zum Raspberry erfolgt über Ethernet, es werden keine weiteren Schnittstellen benötigt.
| |
| | |
| == Software ==
| |
| * raspbian (wheezy)
| |
| ** ser2net
| |
| ** lighttpd (optional für Webclient)

| *** Webserver-Projekt [https://github.com/C3MA/uberschalter Unterordner web]
| |
| | |
| == Konfiguration ==
| |
| | |
| In der Konfigurationsdatei /etc/ser2net.conf von '''ser2net''' aktiviert man folgende Konfiguration. Alle weiteren können auskommentiert werden:
| |
| | |
| 2001:raw:120:/dev/ttyAMA0:9600 NONE 1STOPBIT 8DATABITS -XONXOFF -LOCAL -RTSCTS
| |
| | |
| == Webserver konfigurieren ==
| |
| <code>
| |
| $ cd /var/
| |
| $ sudo chown pi:pi www/
| |
| $ cd cd /var/www/
| |
| $ git clone https://github.com/C3MA/uberschalter
| |
| $ cd uberschalter/web/
