Karl Zweimüller / mRotaryEncoder

Class mRotaryEncoder for mechanical incremental rotary encoders with pushbuttons. Use debouncing and callback-functions for rotation and pressing of button. This version is for old mbed. New version for mbed-os see https://os.mbed.com/users/charly/code/mRotaryEncoder-os/
