Yes, admittedly, I did get a few problems with jitter at first (though
it was surprisingly usable "as is"), so I added an external bounce
eliminator, as specified in the encoder datasheet (an MC4490).
Okay it uses board space and is quite costly, but it has 6 channels so I
could use it for other switches as well, and since the project is pretty
much a one off for my own use, cost wasn't a problem. YMMV...
