Thread: Embedded MP3?

I am trying to do this with a single board 386 with the lp3 music.

The major problem with using non-pc hardware is interfacing to a large storage medium. There have been some people who have interfaced an IDE harddrive to a microcontroler. That and the fact that you will have to use some sort of dedicated hardware decoding scheme for every thing to work.

In general it is easyer to put together a player from standard parts and software than designing hardware and hand tuning assembly code.

Like I said I am trying to implment a car player on minumal hardware with hardware decoding. I will be using on of the embedded linux distros for the os with the lp3 player/data manager and driver.

I am not saying that this cannot be done but there is a large knowledge factor here. Use what you know and implement it.

I thought about creating an mp3 box with a low-end cpu also, but I was just thinking that using a full size computer seems to be overkill. I mean, mp3 decoding could be as simple algorithm as:

access mp3 file (using microcontroller) -->
decode mp3 file (using digital signal processor) -->
digital-to-analog converter -->
RF modulator or any output...

The PC parts and accessories in combination accomplishes this well, but with the overhead of an multitasking OS (Windows, Linux).


I guess you are right when it comes to the technical know-how...
Any hacker out there who wants to try... let me know...
