Development

Copy music to Audio shield

• Insert memory card into Audio shield

• Stack Audio shield and Audio and connect them to your computer via a USB cable. And you'll see a disk on the computer.

• Copy songs to the disk.

Thumbwheel 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
• 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: " audio.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 " audio.h " based on the core modules you use.

//#define AUDIO_PORT Serial1    
#define AUDIO_PORT mySerial

2. Initialize Audio module and select play mode.

#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

• 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.

• 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.

• 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.

• Operation Description:
  • Press down the thumbwheel to play or pause.
  • Toggle right or left to change songs.
  • Keep toggling to the right or left to adjust the volume.
