- Wed Jan 31, 2018 5:09 pm #73621 Ok, I added it, so now my pins are:

RX(serialRX) -> 270 ohm resistor -> Base
esp8266 Ground -> Emitter
Speaker (-) -> Collector
Speaker (+) -> +5V

And still i get:

When using this sketch:

Code: Select all#include <Arduino.h>
#include "AudioFileSourceSPIFFS.h"
#include "AudioGeneratorMP3.h"
#include "AudioOutputI2SNoDAC.h"

AudioGeneratorMP3 *mp3;
AudioFileSourceSPIFFS *file;
AudioOutputI2SNoDAC *out;
void setup()
{
  Serial.begin(115200);
  delay(1000);
  SPIFFS.begin();
  file = new AudioFileSourceSPIFFS("/ring1.wav");
  out = new AudioOutputI2SNoDAC();
  mp3 = new AudioGeneratorMP3();
  mp3->begin(file, out);
}

void loop()
{
  if (mp3->isRunning()) {
    if (!mp3->loop()) mp3->stop();
  } else {
    Serial.printf("MP3 done\n");
    delay(1000);
  }
}

- Wed Jan 31, 2018 6:28 pm #73624 What happens if you have the speaker disconnected?

- Wed Jan 31, 2018 6:58 pm #73625 Interestingly a similar error:

Note i . still have both my Serial wires to my programmer plugged into pins TX & RX when doing this. I doubt that's the issue though, wanted to note it.
