Arduino and mp3

Ebay's YX5300

A very cheap 4.5 USD serial module on eBay. Bought 2 and very happy! Fast and efficient. Ok, you have to know a few things and fining doc is a bit hazardous but doable.

Some gentelman share his experience (in Polish)

For the doc search for Catalex if you're lucky or see below:

YX5300 Serial MP3 Player v1.0 Manual.pdf and YX5300-24SS Datasheet V1.0.pdf

#include 
 
SoftwareSerial mp3(8, 9);
 
static uint8_t cmdbuf[8] = {0};
 
void command(int8_t cmd, int16_t dat)
{
  delay(20);
 
  cmdbuf[0] = 0x7e;  bajt startu
  cmdbuf[1] = 0xFF;  wersja
  cmdbuf[2] = 0x06;  liczba bajtow polecenia
  cmdbuf[3] = cmd;   polecenie
  cmdbuf[4] = 0x00;  0x00 = no feedback, 0x01 = feedback
  cmdbuf[5] = (int8_t)(dat >> 8);  parametr DAT1
  cmdbuf[6] = (int8_t)(dat);   parametr DAT2
  cmdbuf[7] = 0xef;  bajt konczacy
 
  for (uint8_t i = 0; i < 8; i++)
  {
    mp3.write(cmdbuf[i]);
  }
}

void setup()
{
  Serial.begin(9600);
  mp3.begin(9600);
 
  delay(500);  Czekamy 500ms na inicjalizacje  
 
  command(0x09, 0x0002);  Wybieramy karte SD jako zrodlo
  delay(200);  Czekamu 200ms na inicjalizacje
 
  command(0x06, 15);  Ustaw glosnosc na 30
  command(0x03, 0x0001); // Otwarzamy pierwszy utwor (kolejnosc nieposortowana)
}
 
void loop() { 
  if (Serial.available() > 0){
     byte c = Serial.read();
     
     switch (c){
       case 'n':
         command(0x01, 0x0000);
         Serial.println("Next!");
     }
  }
}
