Hello I am using Arduino IDE 2.3.3 and a M5stack core 2.
I have found that M5.Speaker.playWav will work for me when I call on it within void setup() but I am unable to use the same M5.Speaker.playWav function in void loop().
Is there a work around or another option for me that would get my wav file to play during the point in the loop I would like it to ?
void playSuccessChirp(){
Serial.println("Success Tone Activated");
M5.Speaker.tone(420,1000);
delay(1000);
// Load audio files and write to buffers
success_chirp = LittleFS.open("/success_chirp.wav", "r");
success_chirp_fileSize = success_chirp.size();
success_chirp_Buffer = (uint8_t*)malloc(success_chirp_fileSize);
success_chirp.read(success_chirp_Buffer, success_chirp_fileSize);
success_chirp.close();
Serial.println("Tone Chirp Activated");
M5.Speaker.playWav(success_chirp_Buffer);
delay(2000);
