using M5.Speaker.playWav in void loop()
-
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); } void setup(void) { Serial.begin(19200); auto cfg = M5.config(); M5.begin(cfg); M5.Display.begin(); SPIFFS.begin();
