1>. "key combination play" : Return to the original high level after the corresponding level from I/O0-I/O7 output, similar to the key triggered once.Similar instantaneous switch.
2>. "Level combination play" :The trigger signal remains the same, similar to a self-locking switch.
3>.The difference between “I/O Integrated/Independent Mode 0” and “I/O Integrated/Independent Mode 1” :Mode 0 will continue playing the current song to the end after release level .Mode 1 will stop playing immediately after release level.
Mode Operation Instruction:
1>. I/O integrated mode 0(Key combination playing).
It will stop playing current song to the end after I/O0-7 release input signal(return to high) at 'I/O Integrated Mode';It will playing new song when get new input signal during playing and stop after end of song;It will play repeatedly if keep input;Busy pin will output valid signal(High) during playing.
Note: the song must be named for 5bit.
2>. I/O integrated mode 1(Level combination playing)
It will keep playing current song when get trigger signal.It will stop playing immediately after release level. Busy pin will output valid signal(High) during playing.Note: the song must be named for 5bit.
3>. I/O independent mode 0((Key independent controlling)
I/O0-I/O7 independently controls 8 songs.It will stop playing current song to the end after I/O0-7 release input signal(return to high);It will playing new song when get new input signal during playing and stop after end of song;It will play repeatedly if keep input;Busy pin will output valid signal(High) during playing.
Note: the song must be named for 5bit.
4>. I/O independent mode 1(Level independent controlling)
I/O0-I/O7 independently controls 8 songs.It will keep play repeatedly specify the triggered song.It will stop playing immediately after release level.Busy pin will output valid signal(High) during playing.
Note: the song must be named for 5bit.
5>. UART serial port mode
5.1>. Communication format
Adopt full duplex serial port communication;
Baud rate 9600, data bits 8, stop bit 1, check bit N.
Start code - command type - data length (n) - data 1- data n- and test (SM)
Command code: fixed to 0xAA.
Command type: used to distinguish the type of command.
Data length: the number of bytes of data in an command.
Data: the relevant data in the command, when the length of data is 1, means that there is only CMD and no data bits.
Test: it is low 8 bits of the sum of all the bytes. that is, When the starting code and the data are added, take out low 8 bits.
Data format: sent data or command, high 8-bit data is in front, low 8-bit is in the back.
5.2>. Communication protocol
The following is a data definition for the return and identification of the chip.
A. Playing State definition: the system is on the stop state when power on.
00(stop) 01(play) 02(pause)
B. Disk character definition: it is stopped after the switch disk.
USB:00 SD:01 FLASH:02 NO_DEVICE: FF.
C. Volume: the volume is 31grades, 0-30.The default is 20grade.
D. Play mode: the default is the single stop when power on.
Cycle for all songs (00) : play the whole songs in sequence and play it after the play.
Single cycle (01) : play the current song all the time.
Single stop (02) : Only play current song once and then stop.
Random play (03) : random play.
Directory loop (04) : play the songs in the current folder in order, and then play them after the play. The directory does not contain subdirectory.
Directory random (05): random play in the current folder, and the directory does not contain subdirectory.
Directory order play (06) : play the songs in the current folder in order and stop after the play. The directory does not contain subdirectory.
Sequential play (07) : play the whole songs in order and stop after it is played.
E. EQ definition: the default EQ is NORMAL(00).
NORMAL(00) POP(01) ROCK(02) JAZZ(03) CLASSIC(04)
F. Composition play definition: combination play is combined by filename. The file requirements are stored under the "XY" file. You can change the name of the file you want to combine to two bytes, which is generally recommended as a number. Such as: 01. Mp3, 02. Mp3.
