Helly everybody,
I searched a lot about my problem and while I was searching i learned a lot but I still have a small problem. I am using an Arduino Leonardo with CTS288 rotary encoders (2bit gray code). First the sketch only noticed every fourth "click" of the encoder. After hours of testing and searching the internet I made it to a point where the sketch reads every second click of the encoder. So I'm thinking we are in HALF_STEP now reading 1-1 and 0-0 positions of the encoder. Can someoene pls have a look on my code and tell me how it is possible to read all the clicks of my rotary? I am absolutely new to Arduino. The Sketch is for a buttonbox, 10 buttons, 2 rotaries.
