Does someone knows any reference design for a stand-alone mp3 decoder which can be used in an Aiwa cd system?
Has someone worked on Atmels 8xc51 based mp3 decoder chips?
Who can help with the mp3 algorithm?

mp3 reference design

Visit www.mp3projects.com .It has a lot of information and some designs based on AVRs. There is no need to implement an mp3 decoder, because there are several dedicated mp3 decoder chips with a lot of extras (on-chip DAC etc).

mp3 c reference

You should look at www.mp3ar.com. it has so good reference design that hardware and software are free. The projects that are represented based on micronas and vs1001k.

what is mp3 ref

This is a schematic bus, very common thing in larger schematics as it keeps the schematic clean and understandable.

The wires are not connected together, they are still connected to their respective nets.
For example AD5 is connected to pin49 of the ATMega and both U2 pin7 and R1 pin6

Cheers

avr mp3 project using sta015

Hi. Thanks a lot for help. But unfortunately I didn’t get the meaning very well though. I have to ask you again, sorry. How do I have to connect the circuit as a whole thing from page to page then please? The black lines are still confusing me, that’s why. If I understood well I don’t have to connect them all together right? Please can you help me more? Thanks a lot though. Thanks.

Robert.

sta013 mp3 decoder

Yes the black lines as you say are not connected together.
They are shown like this to simplify the schematic, you still treat the nets as separate connections.

Like i said before AD5 is only connected to AD5 on each end of the bus. And so it is not connected to AD4 for example.

Lookup schematic bus in your schematic package for more details.

Regards

esquematic sta013

Hi thanks a lot for the information. It was very clear. I now understood it. Thanks again for your help. The last thing please. Can I ask you about the source code? Can you tell if it will work please? And from what you have seen in the circuit page you think the project will work? Is it worth it to try? The final thing. Please can you tell me if I can program the Microcontroller from the board directly or I need to program it separately please? Thanks a lot for those how helped me. Your bit was very big to me. Thanks again every one.

vs1001 mp3 decoder in india

I would imagine it will work fine, cannot see any reason why someone would put a non working project on the net.
Looking at the schematic it has a ISP header so the micro can be programmed on board.

sta015 avr

Do you have an idea for the 6 buttons to interact with the MP3 and the power supply please? For the supply the document talked about MAX710, a steady 5v and 3.3v, shutdown feature, micropower regulator allowing the processor to turn off the MP3 player, hibernation, wait for user to perform an on-button click to revive the player.

dac3550a driver source code

I have not used this design, but looking at the source the buttons have not been implemented yet.
So its upto you to add the button interface, just pick a spare port such as PORTF would be a good choice.
