I can't figure out how to clear audio buffer. An i tried serial.flush it wont work.
Is there any other way?
Which "audio buffer" ?
I can't explain here is the begining of the code. I have more than one file that i want to play in seperate times. The first one plays fine, but the next ones, is slow and not smooth.
I think it's becous the buffer fills up. Or something like that.
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);

return;
