Guys,
How to pass the content of SDcard to VS1003 ?
I have tested for reading SD card and testing sound on VS1003 and it works....
Here's the function....
while (p <= &HelloMP3[sizeof(HelloMP3)-1])
{
VS1003B_WriteByte(pgm_read_byte(p++));
}
How can I change HelloMP3 to test.mp3, any clues folks ?
thanks
