| VS1011 got crash sound when play MP3 |

I can play mp3 with vs1011 up to 320kbit, it play smooth but after 1 or 2 sec it sometime interrupt zzz, it same with lowest bitrate 32kbit. It's strange because 320kbit and 32kbit still play OK but it got crash sound.
I using PIC16f887 with 20M OSC and vs1011 with 12.886M, I set CLOCKF = 0x9800.
First time, I set block_data = 64bytes, its same. Next I set to block_data = 256 its not different.
I so confused about that zzzz.
This is code I use to tranfer data from SD Card to VS1011.
| Code: |
for(ii=0;ii<8;ii++)
{
while(!input(DREQ));
output_low(XDCS);
for(i=0;i<32;i++)
{
spi_read(0xFF);
}
output_high(XDCS);
}
|
With ii=8 to equal with block_data = 256.
When I set ii= any value, it still got crash sound when play any bitrate Mp3.
Thanks for read my question, I hope someone can help me fix this crash. |

Hello Dear!
I also program for PIC16F887 and VS1011e + SD Card
But it doesn't play.
