• Unable to schedule a timer Error in Waveform Example

  in ESP8266 • 8 years, 4 months

  

  Firstly, I saw the PWM does not work. Code exists but doesn't work. in the ESP8266 reference.
  But when I tried the simple example ( analogWrite(D12, 0.5)) , I measured the voltage half of 3.3V at the D12 pin. So I thought that PWM is running. And then,

  I tried Waveform example but I can not run this example on ESP8266.

  var s = atob("f4GBgoODh5GtnmgkE1m435g/MobgzYJbd41YHkHD/7UoEZPysyscl/K5PSqLy5tLToqdfHGdrXI1V7vUeiVIqceEUG2kmWVfj6qIWFuKpZFpXXiXknNthZB9cH6LgG5vgJKSdWF7oZVoXHuRioJ8c3iJjHtweomLf3JygpCHdHOCiYJ8fYCBg4ODgn53d4CGiIZ8cHGAjo1+dn6Jh3pzeoWHfXd8hYd8d3+Gg3t1e4F9d36KiHp0fYZ+cneLlol3cnyEgXt8g4WBeXV8hoqDdnOCjoNxc4aRhnd3f4J6cXmNlIJxd4mKeXJ5iI2Denh9fX1/f4B/g4N2bnuSlYJzdoOIgXp7g4V+dnmDhoF9gIF+eHqDioJyb3+Oi3xzeIOHgXp7gIB+fH+DgHt8hIh/cnOEjoVzb32Mi3pxeYeLf3N2hIqBdXaBhoB7fYSGfXZ7hYeAeXl9goJ9e36BgYGCgoF8e4GDgHp6f4ODgHo=");
  var w = new Waveform(s.length);
  w.buffer.set(s);
  BUZZER = D12
  analogWrite(BUZZER, 0.5, {freq:20000}); 
  w.startOutput(BUZZER,4000);
  

  I got WARNING:Unable to schedule a timer. error.

  How can I fix it ? or Is the PWM does not run yet on ESP8266?
