hi,
I want to built an HDD MP3 player which can be controlles by Pioneer radio.
I know that its already made, see Yamp3usb and vitats adapter, but I want use an USB2.0 chip for faster fileload and STA013/CS4334 for better soundquality.
but I have some questions about IP bus ( adapter ).
what happens when I connect the adapter while HU is running for example at tuneroperation?
will the adapter successful recognized? so I can change to CD changeroperation whitout problems?
what happens when I disconnect the adapter while HU is running ?
will the HU successful recognize that there is no more cd changer?
oder could it be that he HU software crashs so I have to reset or turn OFF the HU?
what happens when a MD changer is also connected together with the adapter?
the background for these questions is that i have to decide the circuit design.
1. the controllpart is at the main mp3 player, so it would be disconnected while I have it at home for downloading files
2. the controllpart ist separated from the main player like vitalis, so that the HU views altimes a changer ( an empty if mainpart is disconnected )
it will be take a few days until ich become a running adapter because i have to order some parts for the adapter.
then I can start tests an maybe I will answer my questions by my self if nobody has tested it befor.
I measuring up to now that the ASENBUS, BUSP1 and BUSM1 is enable as long as the ACC ( ignition ON ) in enable even if HU is turned OFF.
see you
