Among other things, if you build a software state machine to track the
changes, debouncing will be automatic. Sure, you may bobble between A
is high, B is high back and forth with A is low, B is high (or A is
high, B is low) (in other words both sides of the transition) but it
doesn't matter because only one line is changing states - you wont go
from A is high, B is high to A is low, B is low.
You aren't transitioning far enough to upset the count or miss a
detent position. But you can detect the difference between increase
and decrease.

Yes, even I managed to make the software for a encoder of this type work, and that says something!
Good thinking really that quadrature stuff...
