DiY: MP3 player with ATmega64 VS1011a and Samsung E700 color Display

This is my new mp3 player.

For this MP3 player is new: the display and a new graphical interface explorer.

Knowing that the display of the Nokia 6100 is an old and extremely poor quality, I thought to exchange it with one TFT display ( higher quality ) , by doing this I thought I make an new interface, and this is the result:

-File type played (VS1011): Decodes MPEG 1.0 & 2.0 audio layer III
(CBR, VBR, ABR); layers I & II optional;
WAV (PCM + IMA ADPCM)
-File type played (VS1033): Decodes MPEG 1 & 2 audio layer III (CBR
+VBR +ABR); layers I & II optional;
MPEG4 / 2 AAC-LC-2.0.0.0 (+PNS);
WMA4.0/4.1/7/8/9 all profiles (5-384 kbps);
WAV (PCM + IMA ADPCM);
General MIDI / SP-MIDI format 0 files
-File type played (VS1053): Decodes Ogg Vorbis;
MPEG 1 & 2 audio layer III (CBR +VBR
+ABR); layers I & II optional;
MPEG4 / 2 AAC-LC(+PNS),
HE-AAC v2 (Level 3) (SBR + PS);
WMA4.0/4.1/7/8/9 all profiles (5-384 kbps);
WAV (PCM + IMA ADPCM);
General MIDI 1 / SP-MIDI format 0 files

For bitrate higher than 320Kb/s is necessary to increase the CPU frequency from fuses for 4Mhz to fuses for 8Mhz internal RC

This project is under develop.

Mp3 Player with Media Player skin Download demo hex fileThe fuse bit be set for 4Mhz Internal RC Oscillator

Mp3 Player with Half Life skin

This player run 2 threads , one for navigating and one for serving data to VS1011.

The last rectify of compatibility of Fat32 filesystem library and Player data service library has increase the transfer rate , in this moment the player is capable to read 256Kbit/s melody at 4Mhz internal RC clock with osccal=199(default), and 320Kbit/s at 4Mhz and osccal=255 (approximately 5Mhz) internal RC clock.

Now i work to one explorer configured from skin file like XML file.

This navigator display the short filename if the long file name is not writed on the name of file.

For support post a comment






This project was abandoned for another more powerful.

DiY: most tiny MP3 player with ATmega8 VS1011a and Nokia6100 Display

This is a complete mobile MP3 player and first mp3-player with ATmega8 and Nokia 6100 color display.

An demo firmware and gerber file for board will be available soon.

This player has capability to play wav and mp3 files and view BMP files on 8 or 24 bits/pixel from a MicroSD card with maximum capacity 2GB, the format of the SD is FAT32 with clusters from 512 Bytes to 32768Bytes, the filesystem has no limits in number of directories and files.
For future i want to adapting the SD driver for SDHC because the filesystem is designed to use all capacity of fat32 ( 2TB in 512Bytes/sector)

List of features:
Play Wav and MP3 Files because the VS1011a only this files is capable to decode( but for future in this project i want to include the VS1053 chip to play more file formats.
View Bitmap files on 8Bit and 24 bit/pixel

This project is in asm language and my 100% own libraries









For the moment the project has 5172Bytes of Flash , 663Bytes of Ram and 0Bytes of EEprom

I work to another MP3 player:
