hello guys

I just get WT5001M02-28P, I read all manuals that I found on the web but I did not find what I need.
However I have few questions as I'm using PIC 18F45K22 MCU, Mikroc with easy pic development board of mikroelectronika over windows 7 64bits :

1) Is there any example of comanding this audio module through a microchip microcontroller ?
2) I need in my first application at start, playing a music, I used the following code but sometimes  I hear the music and lot of times not !!! is there any mistakes ?  >:(

 //playing file track 1  from SD card
     UART1_init(9600); 

     UART1_Write(0x7E);  // set volume max
     UART1_Write(0x03);
     UART1_Write(0xA7);
     UART1_Write(0x1F);
     UART1_Write(0x7E);
     delay_ms(10);

     UART1_Write(0x7E);
     UART1_Write(0x04);
     UART1_Write(0xA0);
     UART1_Write(0x00);
     UART1_Write(0x01);
     UART1_Write(0x7E);
     delay_ms(300);

3) I used iSound.mp3 (for another application) for automatic playing mp3 files at power on and cycling
but at my surprise it never functions !!!!  :smiley-twist:

sp01//
cl02//
cf1F 00 0D 78//

perhaps "iSound.mp3" is misspelled ?  :smiley-sad-blue:

4) can I control this audio module through spi lines instead of UART and how?
5) how to update the firmware and where can I find it?
6) is it possible to get the firmware source ?
7) how to know the spi flash size ?
8) how to erase spi flash when no use ?
9) how to enable/disable EEprom automatic saving of audio infos (last song palyed, volume ...etc) before power down?
10) how to read the EEProm from MCU?

Please help me and thanx in advance  :)
