  //example #1
  var step = 0;
  function encFun(){
  var a = digitalRead(C6);
  var b = digitalRead(C8);
  //  print('a', a);
  //  print('b', b);
     if (a == HIGH && b == LOW){
       step ++;
       print(step);
  return;
  }
  else if (a == HIGH && b == HIGH){
         step --;
         print(step);
  return;
  }
  }
  setWatch(encFun, C6, true);

  Hi. I am new in Espruino and JS.
  I have linear encoder with 0.005mm step.
  When I move encoder slow. It is about 1Khz for channel.
  All is fine. Program make count.
  But I need more faster works. It is about 200Hhz for channel. It will 1000mm/sec.
  Program don`t see steps when move with 1000mm/sec.
  Can you give advice?

  I try save(); dont work.
  Bottom is ok.
  It is code for example.
  var on = false;
  setInterval(function() {
  on = !on;
  LED1.write(on);
  }, 2000);
  save();
