mCookie-Audio is an audio play module with serial communication. It uses memory card to save songs to Audio Shield and amplifies sound together with [[mCookie-Amplifier]]. Audio and Audio shield stacked can be stacked to computer and serves as a card reader, which can be used for file transmission. 







==Features==
*Adopt serial port control with default serial (D2,D3). Serial port can be selected by jumpers: Serial (D0, D1), soft serial port(D4, D5).
*Allow external memory card connection and play as well as disk display while connecting with a computer and content update. 

==Specification==
* MP3 format:  
*Support asynchronous serial communication mode and receive commands sent from the upper computer by serial port:    
**Communication standard: 9600 bps  、
**Data bit:1 
**Check bit: none 
**Flow control: none
*Support FAT16 and FAT32 system as well as 32G memory card to the maximum
*With broadcast language insertion function, you can pause the playing background music.   
*Audio data is sorted by folders with 100 folders at the most supportable. Each folder can be sorted with 1000 pieces of music. 
*30-level volume adjustable (0x00-0x1E)
* * Support Play, Pause, Last one, Next one and Play certain audio

*Copy songs to the disk. 

===Dial Wheel Button Control===
*Hardware needed: [[mCookie-CoreUSB]], [[mCookie-OLED]], [[mCookie-Amplifier]], mCookie-Audio, Audio shield, [[mCookie-BM]], [[mCookie-BM shield]], two loudspeakers and two cells of battery; 
*Code example download: [[File:Music Text.zip|Music Text]]
*Connect CoreUSB to your computer, start Arduino IDE and open example program. 
*Click and upload program. When you see "Uploaded", it means the program has been uploaded to CoreUSB successfully. 
Program description: " arduino.h " is audio file control, responsible for sending control instruction to Audio module.
1. Under default serial port, you can select communication serial port from " arduino.h " based on the core modules you use. 
<source lang="cpp">
//#define AUDIO_PORT Serial1    
#define AUDIO_PORT mySerial 
</source>

2. Initialize Audio module and select play mode. 
<source lang="cpp">
#define MODE_loopAll 0  //Loop all the time 
#define MODE_loopOne 1  //Loop once 
#define MODE_One_STOP 2 //Single cycle 
#define MODE_One_END  4 //Play once 
</source>

*Insert TF card to Audio Sheild slot.

*Stack AudioSheild and Audio, connect the Audio to your computer, and then you can save songs to TF card. Here we can save nine songs.
*Connect loudspeaker to the interface of Amplifier. 
[[file:mCookie-Audio-speck.JPG|thumb|400px|center]]
*Stack Amplifier, Audio and AudioSheild. (Only these three modules need to be connected together. Not for the other modules.)

*Connect the battery pack to the BM module. 
[[file:mCookie-Audio-speck.JPG|thumb|400px|center]]
*Stack the other modules and connect them to BM shield. Then you can system power supply. 
**'''Audio must be powered through BM and it cannot powered by computer via CoreUSB, otherwise, it may cause system breakdown.
