DF Player mini Code

[Suraj143]

Has anyone tried DF player mini (Actually my module is (MP3-TF-16P) to play some sound tracks.I tried with a PIC micro but its not working.I searched examples on the internet & they all have arduino examples

When a button presses the 1st sound track play & after 5 seconds it will pause. Here is what I did, but its not working.

Set_TF_Card        movlw        7Eh
            call        TX_RS232
            movlw        0FFh
            call        TX_RS232
            movlw        06h
            call        TX_RS232
            movlw        09h
            call        TX_RS232
            movlw        00h
            call        TX_RS232
            movlw        00h
            call        TX_RS232
            movlw        02h
            call        TX_RS232
            movlw        0FFh
            call        TX_RS232

I have played with one and gotten it to work. Here are the commands I used.
Reset module (0x7E,0xFF,0x06,0x0C,0x01,0x00,0x00,0xFE,0xEE,0xEF).
Specify Volume (0x7E,0xFF,0x06,0x06,0x01,0x00,0x1E,0xFE,0xD6,0xEF).
Specify Track (0x7E,0xFF,0x06,0x03,0x01,0x00,0x01,0xFE,0xF6,0xEF) First folder, first track.
Next Track (0x7E,0xFF,0x06,0x01,0x01,0x00,0x00,0xFE,0xF9,0xEF)
That should get you up and running. One thing to note, if you don't get the checksum right, it will ignore the command. Hope this helps.
