You can find some information on the following page: http://www.rockbox.org/twiki/bin/view/Main/RockboxPlayer
It contains a link to an MP3 player project using the AVR Butterfly. However, as expected decoding is done with a dedicated chip. If you really insist on decoding the MP3 stream with the Atmega128, you can use the code from this site as a starting point, but I doubt it will be possible in realtime. Even only the transfer of the decoded wave data to an external DAC (44.1 kHz * 16bit * 2 ~ 176 kb/s) is plenty of this processor. AS ankvi wrote: > Heylo, > Thanks for your reply.
