  Hi guys!
  I'm trying to use Encoder lib to get rotation direction from my wheels encoders (https://wiki.dfrobot.com/Micro_DC_Motor_with_Encoder-SJ01_SKU__FIT0450).
  At small speed it's okay and returns correct value. But when I'm trying to rotate wheel a little bit faster Encoder lib starting to print an opposite direction sign.
  What am I doing wrong? Please, help me figure it out.

  const ENCODER = require('Encoder');
  ENCODER.connect(P3,P2,function (direction) {
    print(direction);
  });
  

  Looks like this at slow speed
  1
  1
  1
  1
  1
  1

  And this at higher speed
  -1
  -1
  1
  -1
  1
  -1
  -1
