“0”=low level; “1”=high level

NOTES:”I/O Combination mode 0”IO0~IO7 restore to high level after outputting

      corresponding level, It's like triggering a button once.                  “I/O Combination mode 1” IO0~IO7 always keep the corresponding level

      after Outputting corresponding level.

         The difference between “I/O Combination mode 0”and “I/O

Combination mode 1”is that it still plays music when IOs restore to original

 high level in “I/O Combination mode 0”, and it stops playing music when

 IOs restore to original high level in “I/O Combination mode 1”

The difference between “I/O stand-alone mode 0” and “I/O stand-alone mode 1”is the same as above

 

5. Modes operation instructions

5.1 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.

5.2 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.

Combination mode music Control as follows

NOTEThe music files must be named by five numbers such as 00001.mp3~00255.mp3

5.3   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.

5.4 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. The busy pin is always effective while playing.

5.5.1 Communication format

Full duplex serial communication;

Baud: 9600bps,Data:8 bits ,stop:1bit,Check: N.

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

l ※ Start :fixed AA.

l ※ CMD Type : Used to distinguish CMD types.

l ※ data length:The number of bytes of data in CMD

l ※ data :Data in CMD,there is no data when the length of data is one, only CMD.

l  ※ CRC(SM):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.

5.5.2 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.
