Ajuda - Código MP3

[Tiago Gomes 0]

Amigos Bom Dia.

Comprei um Arduino para aprender a brincar um pouco e estou tendo dificuldade em criar um array para rodar as musicas de forma aleatória e não repetir.. alguém poderia me dar uma luz rs.

 

Este é o código teste...

const int clockPin = 6; // the pin number of the clock pin

const int dataPin = 9; // the pin number of the dataPin pin

const int resetPin = 3; // the pin number of the reset pin

const int botao = 7;

const unsigned int VOLUME_0 = 0xFFF0;

const unsigned int VOLUME_1 = 0xFFF1;

const unsigned int VOLUME_2 = 0xFFF2;

const unsigned int VOLUME_3 = 0xFFF3;

const unsigned int VOLUME_4 = 0xFFF4;

const unsigned int VOLUME_5 = 0xFFF5;

const unsigned int VOLUME_6 = 0xFFF6;

const unsigned int VOLUME_7 = 0xFFF7;

const unsigned int PLAY_PAUSE = 0xFFFE;

const unsigned int STOP = 0xFFFF;

int count;

int ok;

void setup() {

Serial.begin(115200);

delay(500);

pinMode(clockPin, OUTPUT);

pinMode(dataPin, OUTPUT);

pinMode(resetPin, OUTPUT);

pinMode(botao, INPUT);

delay(100);

digitalWrite(clockPin, HIGH);

digitalWrite(dataPin, LOW);

delay(100);

// reset the module

digitalWrite(resetPin, HIGH);

delay(100);

digitalWrite(resetPin, LOW);

delay(10);

digitalWrite(resetPin, HIGH);

delay(600);

digitalWrite(botao, HIGH);

delay(600);

sendCommand(VOLUME_7);

count = -1;

ok = 0;

}

void loop() {

int r = digitalRead(botao);

//delay(1000);

if (!r)

{

ok = 1;

count++;

delay(150);

}

// play fisrt file, hexadecimal parameter

// Aqui iniciaria a primeira musica a partir de um comando de um botão.

if (count == 0 && ok)

{

ok = 0;

sendCommand(0x0000);

while(digitalRead(botao))

{

Serial.println("Arduino rodando com musica tocando!");

delay(100);

}

}

else if (count == 1 && ok)

{

ok = 0;

sendCommand(0x0001);

while(digitalRead(botao)) delay(100);

}

else if (count == 2 && ok)

{

ok = 0;

sendCommand(0x0002);

while(digitalRead(botao)) delay(100);

}

else if (count == 3 && ok)

{

ok = 0;

sendCommand(0x0003);

while(digitalRead(botao)) delay(100);

}

else

{

ok = 0;

// stop playing

sendCommand(STOP);

count = -1;

}

delay(100);

}

void sendCommand(int addr) {

digitalWrite(clockPin, LOW);

delay(2);

for (int i=15; i>=0; i--)

{

delayMicroseconds(50);

if((addr>>i)&0x0001 >0)

{

digitalWrite(dataPin, HIGH);

//Serial.print(1);

}

else

{

digitalWrite(dataPin, LOW);

// Serial.print(0);

}

delayMicroseconds(50);

digitalWrite(clockPin, HIGH);

delayMicroseconds(50);

if(i>0)

digitalWrite(dataPin, LOW);

else

digitalWrite(dataPin, HIGH);

delayMicroseconds(50);

if(i>0)

digitalWrite(clockPin, LOW);

else

digitalWrite(clockPin, HIGH);

}

delay(20);
