sent out within the time, indicating that the module initialization error, please reset the module's power supply,

and detect hardware connecting;

2).The module initialization data including online devices, such as sending 7E FF 06 3F 00 00 01 xx xx EF, DL

= 0x01 describe only the U-disk online during power-on, Other data are seen as the table below:

U-Disk on-line

TF Card on-line

PC on-line

FLASH on-line

U-disk & TF Card

on-line

3).MCU will not send corresponding control commands until module initialization sending commands or the

module will not process the commands sent by MCU, and will also affect the normal initialization of the

module.

3.3.2 .Returned Data of Track Finished Playing

U-Disk finish playback 1st track

U-Disk finish playback 2nd

TF card finish playback 1st track

TF card finish playback 2nd

Flash finish playback 1st track

Flash finish playback 2nd

1.The module will enter into pause status automatically after being specified playing, if customers need

such application, they can specify track to play ,the module will enter into pause status after finishing

playing ,and wait for the commands sent by MCU.

2 In addition, we opened a dedicated I/O as decoding and pausing status indication. See Pin 16, Busy

1).Output high level at playback status;

2).Output low level at pause status and module sleep;

3. For continuous playback applications, it can be achieved as below, if it finishes the first tracking of the

TF card, it will return

7E FF 06 3D 00 00 01 xx xx EF

3D ---- U-disk command

00 01 ---- expressed finished playing tracks.

If the external MCU receives this command, please wait 100ms. And then sending the playback command

[7E FF 06 0D 00 00 00 FF EE EF], because inside the module it will first initialize the next track

information. In this case, the module can be played continuously.

4. If the currently finish playing the first song, the track pointer automatically point to second song, If you

send a "play the next one" command, then the module will playback the third song. And, if the module

finishes playing the last one, the player will automatically jump to the first pointer, and pause.

5. After specifying device, the module play pointer will point to device root directory of the first track,

and enters the pause state, and wait MCU sending track playing command.
