示例

#include <Microduino_AudioPro.h>
#include <SD.h>

AudioPro_FilePlayer musicPlayer =  AudioPro_FilePlayer(SD);

uint8_t fileNum = 0;  //文件数量

void setup() {
  Serial.begin(115200);
  Serial.println(F("AudioPro(VS1053) Simple Test"));
  pinMode(SD_PIN_SEL, OUTPUT);    //先初始化AudioPro，所以先使能SD卡
  digitalWrite(SD_PIN_SEL, HIGH);
  delay(500);

  if (! musicPlayer.begin()) { // initialise the music player
    Serial.println(F("Couldn't find VS1053, do you have the right pins defined?"));
    while (1);
  }
  Serial.println(F("VS1053 found"));

  if (!SD.begin(SD_PIN_SEL)) {
    Serial.println(F("initialization failed!"));
    return;
  }
  Serial.println(F("initialization done."));

  musicPlayer.setVolume(96);  //left & right 0-127

  Serial.println(F("Enter Index of File to play"));
  fileNum = musicPlayer.getMusicNum();    //可以获取SD卡中曲目列表以及数量
  Serial.print(F("Music Files : "));
  Serial.println(fileNum);
  for (uint8_t a = 0; a < fileNum; a++) {
    Serial.print(F("\t File["));
    Serial.print(a);
    Serial.print(F("]: "));
    Serial.println(musicPlayer.getMusicName(a));   //在此获取对应序号歌曲的文件名
  }

  // If DREQ is on an interrupt pin, we can do background
  musicPlayer.useInterrupt(VS1053_PIN_DREQ);  // DREQ int
}
