Arduino: PCM Audio Play

Install TMRpcm library

cd ~/Arduino/libraries/
wget https://github.com/TMRh20/TMRpcm/archive/master.zip
unzip master.zip
mv TMRpcm-master/ TMRpcm

Edit

cd ~/Arduino/libraries/TMRpcm
vi pcmConfig.h

Pastikan,

#define DISABLE_SPEAKER2

Code

#include "SD.h"
#define SD_ChipSelectPin 4
#include "TMRpcm.h"
#include "SPI.h"

TMRpcm tmrpcm;

void setup(){
tmrpcm.speakerPin = 9;
Serial.begin(9600);
if (!SD.begin(SD_ChipSelectPin)) {
  Serial.println("SD fail");
  return;
  }

tmrpcm.quality(1);
tmrpcm.setVolume(2);
tmrpcm.play("morat.wav");
}

void loop(){ 
  if( tmrpcm.isPlaying()==1 ) Serial.println("is playing");
  }

Fungsi TMPpcm

TMRpcm audio;
audio.play("filename");    plays a file
audio.play("filename",30); plays a file starting at 30 seconds into the track
audio.speakerPin = 11;     set to 5,6,11 or 46 for Mega, 9 for Uno, Nano, etc.
audio.disable();           disables the timer on output pin and stops the music
audio.stopPlayback();      stops the music, but leaves the timer running
audio.isPlaying();         returns 1 if music playing, 0 if not
audio.pause();             pauses/unpauses playback
audio.quality(1);          Set 1 for 2x oversampling
audio.volume(0);           1(up) or 0(down) to control volume
audio.setVolume(0);        0 to 7. Set volume level
audio.loop(1);             0 or 1. Can be changed during playback for full control of looping.

Pada saat lagu dimainkan aplikasi loop akan jalan terus.
