AVC-LAN
AVC ist die Abkürzung für: Audio Video Communication - Local Area Network.
Hier mal ein paar nützliche Links zur Einführung:
- AVC-LAN.pdf - AVC-Lan Beschreibung von elinux.org
Und Github Projekte:
- AVC-LAN-Module-Builder - neues aktuelles Projekt, ist wohl interessant
- http://flux242.blogspot.com/2007/09/avclan-iebus-sniffer-and-device.html - kein Github, pass aber hier gut her
Signal Analyzer
Protokoll
Broadcast
- 0xFFF - Genereller Broadcast
- 0xYFF - Group Broadcast wenn Slave-Adresse != 0xFFF ist.
y = Gruppe für die Die Broadcast gilt (hier meistens 0x1 ⇒ 0x1FF
Nec µPD72042 Datasheet - s. Gruppen
siehe auch: https://en.wikipedia.org/wiki/IEBus (basiert wohl dann auf mode=2)
