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).
