Product description

I/O Combination mode 0

MCU I/O output corresponding level to trigger specified music and release the IO level to high, it stops playing music after completing playing current music; It will play the new music, if retrigger the music while playing. If keep the triggering state, it will keep playing circularly. The busy pin is always effective while playing.

I/O Combination mode 1

MCU I/O output corresponding level to trigger specified music and keep the triggering state, it will keep playing circularly. It will stop playing immediately when release to original high level anytime. The busy pin is always effective while playing.

I/O stand-alone mode 0

IO0~IO7 control 8 pieces of music，one IO only control one piece of music; IO trigger specified music by falling edge level and restore to original high level, it stops playing after completing playing the triggered music. It will play new music, if retrigger the music while playing；If keep the triggering state, it will keep playing circularly. The busy pin is always effective while playing.

I/O stand-alone mode 1

IO0~IO7 control 8 pieces of music，one IO only control one piece of music; IO trigger specified music by low level, and it will keep playing circularly if keep the triggering state. It will stop playing immediately when release to original high level anytime. he busy pin is always effective while playing.

Description of path format

Path format as follows

1. Specified all music in “XXX” folder in root directory:/XXX*/*MP3

2. Specified music in root directory:/YYY*MP3 “YYY” is the music name

3. Specified a piece of music in “XXX” folder in root directory:/XXX*/YYY*MP3 “XXX” is the folder name, and “YYY” is the music name

Description：

（1）The path starts with “/”（2）XXX is the folder name，YYY is the music name; The length of ” XXX ” is max 8 bytes,and the length of ”YYY” is also max 8 bytes, all letters are required to be capitalized,regardless of whether the folder or file name is capitalized.（3） A letter is a byte（4） Play the first music in “DY” folder：/DY*/00001*MP3（5） Play the 255th music in “DY” folder：/DY*/00255*MP3（6） Play the 65535th music in “DY” folder：/DY*/65535*MP3（7） Play the first music in root directory：/00001*MP3（8） Play the 255th music in root directory：/00255*MP3（9） Play the 65535th music in root directory：/65535*MP3（10）Testing the specified path playing by uart tuning tool.

UART Control Mode:Communication format

Full duplex serial communication；Baud: 9600bps，Data：8 bits ，stop:1bit，Check: N.

Start-CMD Type-data length（n）-data1－data n－CRC(SM)

CMD CODE ：fixed AA.CMD TYPE : Used to distinguish CMD types.DATA LENGTH：The number of bytes of data in CMD DATA ：Data in CMD，there is no data when the length of data is one, only CMD.CRC ：The sum of all data from the start code to the end data before the CRC, and select the low 8 bits.DATA FORMAT：Send the high 8 bits first, and the low 8 bits follow.

UART Control Mode:Communication Protocol

The definition of data as follows.

1. Definition of playing state ：It is in stop state when power on.00(Stop) 01(Play) 02(Pause)

2. The definition of devices: It is in stop state when switch device.USB:00 SD:01 FLASH:02 NO_DEVICE：FF

3. Volume：The volume all is 31 steps which is 0-30，it is 30 steps when power on.

4. The definition of playing modes：It is in single stop mode when power on.Full cycle(00)：Play all music in sequence.Single cycle(01)：Play the current music always.Single stop(02)：Stop playing after playing the current music once.Random broadcast(03)：Play music randomly in device.Repeat folder(04)：Play all music in current folder in sequence.Random broadcast in folder(05): Play music randomly in current folder. Order play in folder (06)：Play music in current folder in sequence,and stop when complete playing the last music.Order play (07)：Play music in device in sequence, and stop when complete playing the last music.

5. Definition of EQ：It is NORMAL (00) when power on.NORMAL(00) POP(01) ROCK(02) JAZZ(03) CLASSIC(04)

6. Definition of combination play：It is combined by file name, the file is stored in ZH folder，the file is named as two bytes , the number name is recommended such as 01.mp3, 02.mp3, and it is also named by two letters.

Customers say

Customers find the MP3 player works well with both SD and TF cards, offering crystal clear audio and being simple to set up and use. They appreciate the audio quality features, with one customer noting the built-in amplifier and three mode switches for different play options. However, the functionality receives mixed feedback, with some customers reporting it works well while others say it doesn’t work at all. Additionally, the product lacks documentation, and while the memory card reader is functional, some customers mention needing a micro SD card.
