Hi all, I am starting a project involving the emulation of a cd changer, it will permit to play mp3 files (but also midi, mods, and any other audio file...) from a storage source (flashdisk, hard drive, internet radio...) and pilot all functions via the head unit.
For now I think to use a PIC for the interface with the head unit via the DIN 13 connector on it's back.
Audio playing will be imlemented on a raspberry pi, maybe in future also the interface part will be assigned to raspberry, thus permitting to eliminate the PIC part.
The first problem I have is about the Kenwood's protocol, the specifications have not been released by Kenwood and the only information I have found is on sites like this:http://www.adriangame.co.uk/kenw-dc-pro.html
So, I'm asking if someone is able to send me some more information or other sources of information about Kenwood's interface protocol.
Time to receive the DIN 13 male connector ordered on ebay and i'll start to try to talk to the headunit...
