I have about 25 audi files. I only opet one at a time. When the first one opens it's fine it goes smoothly, but when the second opens the sound is not smooth It's like stoping ever half seconds. I don't know how to explain it better.
I'm running it on arduino due, my code is a bit long, becaus it's not only audio, but the audio is at the begining ithe first 100 lines. I'll upload it as a sketch.
Here are the problematic lines:
int volume = 1024;
const int M = 1024;
short buffer[M];
const int chipSelect = 52;
File myFile;
int TacniOdgovori = 0;
int NeTacniOdgovori = 0;
int x = 1;
File audioFile;
File audioFile2;
void show_tft(void)
{
tft.begin(identifier);
tft.setRotation(3);
tft.setCursor((tft.width() - 36) / 24, (tft.height() * 1) / 4);
tft.setTextSize(2);
tft.fillScreen(BLACK);
tft.setTextColor(CYAN);
tft.println("Zdravo ja sam Limeni.");
tft.println("");
tft.println("Ako zelite da zapocnete kviz pritisnite '#'");
tft.println("");
tft.println("Ako zelite da zpocnet anketu pritisnite '*'");
}
void setup() {
Serial.begin(9600);
Serial.print("Initializing SD card...");
pinMode(SS, OUTPUT);
if (!SD.begin(chipSelect)) {
Serial.println("initialization failed!");
return;
}
Serial.println("initialization done.");
char y = ' ';
Audio.begin(88200, 100);
}
void loop() {
show_tft();
File audioFile = SD.open("zdravo.wav");
while (audioFile.available()) {
Serial.print("Radi");
audioFile.read(buffer, sizeof(buffer));
Audio.prepare(buffer, M, volume);
Audio.write(buffer, M);
}
audioFile.close();
buffer[M];
volume = 1024;
delay(100);
char y = ' ';
while (y == ' ') {
char customKey = customKeypad.getKey();
if (customKey) {
y = customKey;
if (y == '#'){}
if (y == '*'){
goto bailoutB1;
}
}
}
