Grove Serial MP3 Player

This library supports both KT403A and WT2003S.

Grove - Serial Player KT403A

Grove - Serial Player WT2003S

connection of the hardware

Connect MP3 Player to the serial port of the board. In this example, we use software serial as the serial port (D2, D3); If you have other hardware Serial ports on you board, you can also connect to it.

Software usage

• Install Seeed Grove Serial MP3 Player library to Arduino.

• Start a project.

• Verify the MP3 audio chip what you use, then construct an object.

  • If you want to use the functionality Shared by both wt2003 and KT403A.

  #include "SeeedGroveMP3.h"
  #include "KT403A_Player.h"
  #include "WT2003S_Player.h"
  
  // if you user Software Serial
  #include <SoftwareSerial.h>
  SoftwareSerial SSerial(2, 3); // RX, TX
  #define COMSerial SSerial
  #define ShowSerial Serial 
  
  // uncomment the chip what you choose
  //MP3Player<WT2003S<SoftwareSerial>> Mp3Player;
  MP3Player<KT403A<SoftwareSerial>> Mp3Player;
  
  // if you user the Hardware Serial.
  // uncomment the chip what you choose
  //MP3Player<WT2003S<HardwareSerial>> Mp3Player;
  MP3Player<KT403A<HardwareSerial>> Mp3Player;

  Then initialize MP3player in the setup function.

  Mp3Player.controller->init(COMSerial); //use Software Serial.
  Mp3Player.controller->init(Serial1);   //use Hardware Serial1.

  ​ Note: You need to use the controller of Mp3Player to perform the correct functions.

  • If you want to use more features on a specific chip, such as KT403A

  #include "KT403A_Player.h"
  #ifdef __AVR__
  #include <SoftwareSerial.h>
  SoftwareSerial SSerial(2, 3); // RX, TX
  #define COMSerial SSerial
  #define ShowSerial Serial 
  
  KT403A<SoftwareSerial> Mp3Player;
  #endif
  
  #ifdef ARDUINO_SAMD_VARIANT_COMPLIANCE
  #define COMSerial Serial1
  #define ShowSerial SerialUSB 
  
  KT403A<Uart> Mp3Player;
  #endif
  
  #ifdef ARDUINO_ARCH_STM32F4
  #define COMSerial Serial
  #define ShowSerial SerialUSB 
  
  KT403A<HardwareSerial> Mp3Player;
  #endif

  Then initialize MP3player in the setup function

  Mp3Player.init(COMSerial); //use Software Serial.
  Mp3Player.init(Serial1);   //use Hardware Serial1.

  Note: You dont't need to use the controller of Mp3Player to perform the correct functions.

Introduction of the API

KT403A

• No specified folder name or music file name, you can store MP3 files any where in microSD card.

  playSongIndex(index);

• Play music by specified folder and file index.

  playSongSpecify(folder, index);

  Folder and files' names rules:

  01/001***.mp3

  01/002***.mp3

  01/999***.mp3

  03/001***.mp3

  04/002***.mp3

• play music in MP3 folder.

  playSongMP3(index);

  Names rules:

  MP3/0001.mp3

  MP3/0002.mp3

  MP3/0003.mp3

  MP3/0004.mp3

WT2003S

• Play music in SD root.

  playSDRootSong(index);

• Specify the directory and music index to play in SD Card.

  playSDDirectorySong(dir, index) 

  playSDDirectorySong("MP3", 1); mean that play the song 1 in the folder "MP3

• Specify the music name to play in SD Card root.

  playSDSong(fileName)

  playSDDirectorySong("hello.mp3"); mean that play the song "hello.mp3" in the SD root.
