yep...think this is what I was looking for...thanks!! "M. Adam Davis" wrote: I have some amount of rotary encoder info here: http://www.ubasics.com/adam/electronics/doc/rotryenc.shtml It covers very simple decoding (treat A as direction, B as step), then gives an overview of typical state machine decoding. It also covers the different types of encoders, and quotes a few people talking about some interesting absolute encoders. It's not likely the same discussion you remember but perhaps it has the information you need. And if not - ask away! The piclist can never have too many discussions on rotary encoders! -Adam On 9/27/07, alan smith wrote: > I know I have it someplace...stored under something obvious at the time....but there was some posts dealing with rotary encoder interfaces, and now of course I need to recall what was said.... > > anyone remember? > > > --------------------------------- > Yahoo! oneSearch: Finally, mobile search that gives answers, not web links. > -- > http://www.piclist.com PIC/SX FAQ & list archive > View/change your membership options at > http://mailman.mit.edu/mailman/listinfo/piclist > -- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Moving in southeast Michigan?
