ok, so i have the vs1002 up and working just like its supposed to...sorta. i can make it play one song, but when that song is done i cant get it to play a different song below is my code, i think the problem lies with the dataout method but i just cant figure it out for sure, if anyone has one of these working with multiple songs please help.

PUB Start | Bytes, Read, Count, Poss
  MP3.start (11,8,10,9,12)         ' Start mp3 object  
  debug.start(31, 30, 0, 115200)
   
  dira[noparse][[/noparse]13]~
  dira[noparse][[/noparse]14]~~
       
  sdfat.mount(16)
  sdfat.popen(String("wordup.mp3"), "r")
  
  hello := 1 
  outa[noparse][[/noparse]14] := 1
  mp3.SetBassBoost(180)
  
  mp3.SetBassBoost(180)
  MP3.WriteReg(3,33000)
  MP3.SetVolume(220,0)
   
          ' <<-- Change mp3 file name here.
                              ' <<-- Set clock devider. This is verry improtant, if you do not it will play very slowly
  
                                                           ' Volume defalts to zero on startup, so it must be set.

    if ina[noparse][[/noparse]13] == 1
      Poss += sdfat.pread(@SDBuffer,32)
                                                        
      Count~
      if Bytes <  32
        repeat Bytes
          MP3.WriteDataByte(SDBuffer[noparse][[/noparse]Read++])
        sdfat.pclose
        quit        
      MP3.WriteDataBuffer(@SDBuffer)

      Count~
      if Bytes <  32
        repeat Bytes
          MP3.WriteDataByte(SDBuffer[noparse][[/noparse]Read++])
        quit        
      MP3.WriteDataBuffer(@SDBuffer)

Can it be that you have to 'close' the MP3 device as well? I'd expect that the VS1002 does not know how big the MP3 stream is that you send. But the MP3 file has some header information at the beginning. So, if you start sending an additional file it simply thinks that the stream continues instead of reading the first bytes as the next header.

Just a guess.
