This program use the VS1053 library to play a MP3 file. The codec is loaded with a path file or a plug-in. There are many function exposed to set volume and bass-boost.
How to use the library
VS1053Codec codec( p11, p12, p13, p21, p22, p23, p24);
int main( void)
{
codec.init(); // initialize the codec
codec.loadpatch(); // load the patch code (rev 1.5)
codec.setbassboost( 15, 150); // set the bass boost value
codec.settrebleboost( 7, 15000); // set the treable boost value
codec.setvolume( 0x0, 0x0); // set the volume
// snd_piano is a Ogg file stored in flash memory.
int cnt=sizeof(snd_piano)/sizeof(snd_piano[0]);
//
printf("Start playing file snd_piano [%d]\n\r", cnt);
//
int iSize=0;
while( iSize < cnt) {
int count=32;
codec.testdreq();
while( count--) {
codec.writedata( snd_piano[ iSize++]);
if ( iSize > cnt)
break;
}
}
}

Hello Pranav, you must use the LEFT and RIGHT signal and as ground the GBUF signal. As you can see from my schema that use the sparkfun breakout board [1].
Please if you are using the sparkfun breakout board [1] double check if it's the new board with the connection of the TEST pin to IOVDD. From the site: "This new revision uses a new board layout and the TEST pin has also been tied in to IOVDD, no more green wires".
Without this modification the use of the board will be problematic/unusable... :-(

Hi,
Even I am trying to play a mp3 file, but I guess I am going wrong in the circuit connection. Can you please let me know what connections have you made for the audio jack.
I'm sorry, but I have the board without the change. But you can look here: http://www.vsdsp-forum.com/phpbb/viewtopic.php?f=10&t=71

Hey ,
Many thanks for the reply. I am using the older version of VS 1053 along with "https://www.sparkfun.com/products/10588" audio jack. The connections that I have made are as follows:
GBUF .... Gnd
Left .... TSH
Right.... RSH
Also, if you have the new VS1053 board, can u send across an image of the same as I want to see where exactly are the new changes implemented. Many thanks again for the reply.
Regards, Pranav
