Hi, I'm using the Arduino Support Package for Simulink Toolbox. My goal is to make a counter that counts up when it rotates clockwise and counts down when it rotates counterclockwise by using KY-040 Encoder. I can read all values appropriately. (Encoder has 2 output pins, OutA and OutB, and they produce digital signals.) My problem is to take the values I read from the OutA pin and compare them with the new values. Which blocks should I use for this?
