This is really NOT the easiest starter-project if you want
to build this from scratch. Check AVRFreaks (http://www.avrfreaks.net/)
for inspiration. You can buy the mentioned ICs on ebay.com (international
shipping) for less than 20$ or try to get some free samples from the
manufacturers. Check their homepages – they all have some sort of sample-request
form. http://cgi.ebay.de/ST-MPEG-2-5-LAYER-III-AUDIO-DECODER-IC-STA013-MP3-IC_W0QQitemZ350143982337QQcmdZViewItemQQptZBI_Electronic_Components?hash=item350143982337&_trksid=p3286.m63.l1177 http://cgi.ebay.de/MP3-WMA-AUDIO-CODEC-IC-VS1003B-VS1003_W0QQitemZ110307797503QQcmdZViewItemQQptZBI_Electronic_Components?hash=item110307797503&_trksid=p3286.m63.l1177 For quick prototyping you can glue and solder the IC to a
DIL-Socket and use it in a breadboard. Just use the datasheet for the decoder IC to get rolling –
they usually have example setups. At least use a LCD to get some debugging output but I would
suggest you buy a JTAG-Debugger like the AVR-Dragon for such a project befor
you go mad ;) If you really want to do this all in software you should
check the ARM7 32bit Cores - for example Atmel AT91SAM7S256 or LPC2000 from NXP.
They can handle the load as a single chip solution but you will have to take
the coding time into account. For a non-commerical (no-volume) product I would
always go for the decoder IC solution to save time. Regards, Tillmann Krauss |
