1  General / MP3 / YAMPP & IPBUS - All in one? on: 30 Nov 2005, 23:23

Has anyone made a yampp and ipbus transceiver in one pc board using onboard psu etc?

I havent tried this, but it should work as the HU is only acting on what the emulator is sending. So if it sends new information it will update - no matter what sound is comming from the PC.

What's your setup? Smile

What are you connecting the emulator to? You going to use a pc with winamp or did you get a yampp3 ?

I was originally going to put a small mini-itx motherboard into the car, but when I actually got around to it I had all kinds of logistical problems so I ended up ordering a kit for building the yampp3 - Waiting for it to arrive Smile

The firmware of brokly has some extended features. The original source from the main page will also work with most of the basic functionality. Some basic issues are surrounding the updating of the cdtext. You may also try the firmware I attach to this message.

Also, very important - You need to use one of the earlier version of winavr since the code doesnt compile properly with the newer versions. I use avr-gcc version 3.4.1 (WinAVR-20040720-install) for the purpose of compiling the firmware sources.

Note about attached firmware - I found it somewhere on some or the other website - Cant remember where.

The reason I am referring you to the more basic sources is so that you can more easily do your conversion to run on lower crystal frequency - The original code is a lot less complex.

Duh! Thanks Smile

I also tried the winamp emulator version and coudlnt get the firmware to work on the atmega8, *however* the standard firmware supports most of the functions used by winamp so it will actually work mostly anyway.

heh - i'll probably just overclock the mega8l to 14mhz - its not serious, just wanted to make a smaller board for the one that's going into the car.

Hi,

If I change the CPU in the firmware to 161 it compiles fine - If I specify a 162 in the makefile it gives me errors on compile as follows:

--
uart.c: In function `UART_Init':
uart.c:77: error: `RXCIE' undeclared (first use in this function)
uart.c:77: error: (Each undeclared identifier is reported only once
uart.c:77: error: for each function it appears in.)
uart.c:77: error: `RXEN' undeclared (first use in this function)
uart.c:77: error: `TXEN' undeclared (first use in this function)
uart.c:79: error: `UBRRH' undeclared (first use in this function)
uart.c:81: error: `UBRR0' undeclared (first use in this function)
uart.c: In function `UART_SendByte':
uart.c:154: error: `UDRE' undeclared (first use in this function)
make: *** [uart.o] Error 1
--

Any ideas?

Hi

Did you get it working with a 7.3728? I was thinking of using a 8Mhz since I have a few mega8L's TQFP32 which may be useful if I can run the emulator at 8Mhz.

If you didnt get it working pm me your snail address and I'll pop two crystals in the mail for you.

Hi,

Using winamp plugin found here: http://www.vitat.spb.ru/forum/index.php/topic,97.0.html

And a new version of the firmware (ipbus_v5.zip?) which I cant remember where I found it - The one in the forum above didnt work for me.

11  General / MP3 / Re: KEH-M9741ZT is this a ip-bus compatible head unit on: 01 Sep 2005, 20:58
Just a quick thought - Its probably differential BUS (Similar to CAN or IPBUS, which is actually rebranded IEBUS) - You will find they used two busses - One for communication from headunit to cd changer and one for communication from cd changer to head unit.

If you take into consideration that BUS communication usually involves MASTERS and SLAVES I would suspect that TXM+/TXM- would be the Transmit (TX) from the MASTER (being your head unit) - also meaning communication going from the head unit to the cd changer

AND

TXS+/TXS- would be Transmit (TX) from the SLAVE (being the cd changer) inplying that the bus is used for communication from the CD CHANGER (Slave) to the Head unit (Master)

I am just guessing.....
12  General / MP3 / Re: KEH-M9741ZT is this a ip-bus compatible head unit on: 01 Sep 2005, 20:52
It doesnt look good at all.....

I suspect it is not IPBUS after all - The control protocols will probably be hidden in TXM+/TXM- and TXS+/TXS-

In all probability, being older of breed, it may be that it will contain 5volt logic which will be rather easy to see what is going on.

What do you intend doing?

Have a look at the image on the site (http://www.vitat.spb.ru/eng/index.php?L1=ip-bus)

There is a picture of the IPBUS pinout. The connecter on your headunit should resemble that image. It may also be that the connector on the cd changer will look the same.

If so, it is very possible that it may be IPBUS compatible.

The Model number on your post definately looks like a pioneer model number... so it is pioneer... the question is just - is it ipbus compatible?
14  General / MP3 / Re: WinAmp or Yammp & MD,CD or EXT (plugin & HEX inside) on: 31 Aug 2005, 23:04
Is the source for the plugin available?

Care to take a photo of the back?
