Tim, I used only simple encoder, which encodes 2 exclusive bits -)), alias 2 switches triggered by turning with small shaft. It is without electronic, its really like parallel buttons in different mechanical realization. Something like http://www.voti.nl/winkel/catalog.html?M- SW-ROT - datasheet schematics. There are some documents for inspiration as well. I think i need some de-bouncing (thank you for right EN expression).
