模块在繁忙时，有数据过来，模块会返回忙的指令
When the module is busy, the data over, the module will return busy instruction
3.3.1 模块上电返回数据
Returns data on the electrical module 3.3.1
a) 模块上电，需要一定的时间初始化，这个时间是需要根据SPIFLASH 设备的文件多少决
a) On power-up, take some time to initialize, this time is determined based on how much the device file SPIFLASH
定的，一般情况在小于500ms 这个时间。
Given, in general, this time in less than 500ms.
如果超过这个时间模块的初始化数据还没有发
If you exceed this time module initialization data has not been made
送出来，说明模块初始化出错，请检查硬件的连接
Get out, indicating that the module initialization error, please check the hardware connection
b) 模块初始化返回的数据为当前的有效文件夹,譬如返回7E FF 06 3F 00 00 03 xx xx EF==>
b) the return module initialization data for the current valid folder, such as return 7E FF 06 3F 00 00 03 xx xx EF ==>
其中0x03 代表的是FOLDER1 和FOLDER2 这两个区域有有效语音文件如果是0x07 代表
Where 0x03 represents FOLDER1 and FOLDER2 two regions have effective voice on behalf of the file if it is 0x07
的是FOLDER1 和FOLDER2、FOLDER3 都有语音文件实际上，5 个文件夹均占据一个字节
Is FOLDER1 and FOLDER2, FOLDER3 voice file is actually there, five folders are occupying a byte
的一位。

FOLDER 占据最低位
FOLDER occupy the lowest position
c)
c)
MCU 必须等待模块初始化指令发出之后才能发送相应的控制指令，否则发送的指令模块
MCU must wait until after the module initialization command is issued to send the corresponding control instruction or instruction sending module
将不予处理。
Will not be processed.
同时还会影响模块的正常初始化。
But it will also affect the normal initialization module.
3.3.2 模块曲目播放完毕返回数据
3.3.2 Module track finishes playing return data
a) 争对很多的触发型的播放需求，模块更正为播放一曲之后自动进入停止状态。
a) the need for a lot of contention to play triggered, the module automatically corrected to after playing the song comes to a halt.
如果用户
If the user
需要此类应用。
In need of such applications.
只需要指定曲目播放即可。
Only you need to specify the tracks to play.
这样，曲目播放完毕会自动停止，等待指令
Thus, the track finished playing will automatically stop, waiting for instructions
b) Busy引脚作为解码和暂停的状态指示。
b) Busy pin as decoding and suspended status indication.
请参见第5 脚，播放状态输出低电平[很多功放
See 5 feet, playing status output low [lot Amplifier
有静音脚，可以通过此IO 直接进行控制]、播放暂停状态，输出高电平。

也是低电平。
Also low.
模块通电之后，初始化正常，模块会自动进入设备播放状态。
After the module is powered up, the normal initialization, the module will automatically enter the state of play equipment.
并且停止
And stops
解码，等待用户发送播放的相关指令
Decoding, waiting for the user to play send relevant instructions
c)
c)
另外用户在指定设备之后，需要等待200ms 的时间，再发送指定的曲目，因为一旦指定
Also after the user specified device, wait 200ms of time, and then sends the specified track, because once designated
曲目之后，系统会对指定的设备进行文件系统的初始化，如果立刻发送指定的曲目命令，
After the track, the system will initialize the specified device file system, if you send a command immediately designated track,
会导致模块接收不到。
It will cause the module not receiving.

3.3.3 模块应答数据
3.3.3 Module response data
a)
a)
为了加强数据通信之间的稳定性，我们增加了应答处理，ACKB 字节就是设置是否需要
In order to strengthen the stability of data communication between, we have increased the response processing, ACKB byte is set if needed
回复应答。
Echo Reply.
这样做的好处是保证每次通信都有握手信号，收到应答就表示MCU 发送的数
Benefits of doing so is to ensure that each communication has handshaking signals received responses sent to represent the number of MCU
据，模块已经成功收到，马上处理。
According to the module has been successfully received and processed immediately.

自动进入睡眠状态。
Automatically goes to sleep.
d) 只要参考我们给出的测试SDK 程序，移植里面的串口操作部分，就不会出现校验出错，
d) As long as we give the reference test SDK program, which transplant serial operation section, it will not cause an error message,
在这里强烈建议用户使用我们给出的校验方式。
Here we strongly recommend that users give the check mode.

c) 对于选曲，如果选择第100 首，首先将100 转化为16 进制,默认为双字节,就为0x0064。
c) For selections, if you select the first 100, first 100 converted to hexadecimal format, the default is double-byte, it is 0x0064.
DH = 0x00 ; DL = 0x64
DH = 0x00; DL = 0x64
d)
d)
其它的操作依次类推即可，因为在嵌入式领域采用16 进制是最为方便的一种操作。
Other operations and so can, because in the embedded field in hexadecimal is the most convenient method of operating.
3.4.2 指定音量播放指令
3.4.2 specify the volume play command
a) 我们系统上电默认的音量为30 级，如果要设置音量的话,直接发送相应的指令即可
a) on our power system default volume is 30, if you want to set the volume, then sent directly to the appropriate instruction
b) 例如指定音量为15 级,串口发送的指令:7E FF 06 06 00 00 0F FF D5 EF
b) such as specifying the volume to 15, the serial port to send commands: 7E FF 06 06 00 00 0F FF D5 EF
c)
c)
DH = 0x00 ; DL = 0x0F ，15 转化为16 进制为0x000F。
DH = 0x00; DL = 0x0F, 15 was converted to hexadecimal 0x000F.
可以参照播放曲目部分的说明

3.4.4 Single Loop instruction
a) 争对一些需要单曲循环播放的要求，我们改进这一条控制指令0x08。
a) dispute the need for some single loop requirements, we have improved it a control command 0x08.
按照的是存储的物
In accordance with the stored material
理顺序指定，这点请用户注意。
Li order specified, the user's attention to this point.

示例
Example
循环播放开始
Loop Start
7E FF 06 08 00 00 01 xx xx EF
7E FF 06 08 00 00 01 xx xx EF
Playing the first song cycle
Loop Stop
7E FF 06 08 00 00 02 xx xx EF
Loop the second song
3.4.5 combination play command
a) Many applications need to use TTS functionality, such as timekeeping, reported temperature, and so the reported amounts of application, if the user take
Our modules imitate simple TTS function, it may be greatly reduced in the above effect, contradictory point is in the voice
And delayed speech.
Directly in accordance with a specified play a file, then there will be between the speech and voice
延时，这样是不能接受的。
Delay, this is unacceptable.
因此我们增加了组合播放的功能，同时支持指定播放12 个
So we added a combination of playback functions, while supporting the designated player 12
语音，按照串口发送的顺序依次播放。
Voice, in the order of play one serial port.
b) 如果发送7E FF 0C 21 00 05 01 02 03 04 06 07 08 FE B0 EF 这一帧数据，我们分析
b) If the sending 7E FF 0C 21 00 05 01 02 03 04 06 07 08 FE B0 EF of the frame data, we analyze
一下CMD= 0x21 --- 查阅指令表LEN = 0x0c = 12 个字节--- FF 0C 21 00 05 01 02 03
Now what CMD = 0x21 --- repertoire LEN = 0x0c = 12 bytes --- FF 0C 21 00 05 01 02 03
04 06 07 08[去掉红色标记的字节，就是曲目的顺序]模块会一次播放第5 曲、第1 曲、
04060708 [remove byte marked in red, is the order of tracks] module will first play the first five, the first one,
2、3、4、6、7 这7 首曲目。
2,3,4,6,7 seven tracks.
播放完毕就停止
Finished playing stops
c) 在组合播放的过程中，是允许用户进入播放暂停和设置音量，但是不允许指定上下曲。
c) In the process of combination play, the user is allowed to enter the playback pause, and set the volume, but not specify down song.
如果用户对组合播放的要求比较高的话，请用户对音源自行编辑一下，去掉音源头和尾
If the user is playing a combination of high demand, please edit their own user tone look, sound source and remove the tail
的一些静音。
Some muted.
这样就可以减少语音和语音之间的延时，可以采用“Adobe Audition CS5.5”
This reduces the delay between the voice and speech, you can use "Adobe Audition CS5.5"
或者“GoldWave.exe”等等专业音频软件制作。
Or "GoldWave.exe" and so professional audio production software.
d) 有了这个功能，就可以很方便的实现“欢迎光临，现在时间是13 年12 月24 日”这样
d) With this feature, you can easily achieve "Welcome, the time now is 13 years December 24," so
的灵活播报方式，大大提高了产品的竞争力。
Flexible broadcast, greatly improving the competitiveness of their products.
