====== AVC-LAN ======
{{ :avc-lan:avclan_ids_corolla_mp3_projekt.png?direct&400|IDs vom MP3 Toyato Corolla Projekt}}AVC ist die Abkürzung für: **A**udio **V**ideo **C**ommunication - **L**ocal **A**rea **N**etwork.

Hier mal ein paar nützliche Links zur Einführung:
  * [[http://www.softservice.com.pl/corolla/avc/avclan.php| AVC-Lan Projekt - Toyota Corolla MP3-Player]] \\ ({{ :avc-lan:toyota_corolla_mp3_project.pdf |Toyota Corolla MP3 Projekt.pdf}})
  * [[https://elinux.org/images/e/ed/Avc-lan.pdf|AVC-LAN.pdf]] - AVC-Lan Beschreibung von elinux.org

  * [[https://github.com/halleysfifthinc/Toyota-AVC-LAN|Toyota-AVC-LAN]]\\ 
  * [[https://github.com/GadgetNutt/AVC-LAN-Module-Builder|AVC-LAN-Module-Builder]] - neues aktuelles Projekt, ist wohl interessant\\

===== Protokoll =====
==== Broadcast ====
  * 0xFFF - Genereller Broadcast
  * 0xYFF - Group Broadcast wenn Slave-Adresse != 0xFFF ist.\\ y = Gruppe für die Die Broadcast gilt (hier meistens 0x1 => 0x1FF

{{ :avc-lan:nec_iebus_upd72042_datasheet.pdf |Nec µPD72042 Datasheet}} - s. Gruppen
