My favourite Annex as an adventure...

Had ever written a routine for this function but tried this and it works fine. easy piece now.
Don't forget the capacitors on the ports when using a cheap mechanical encoder.

Hidden software surprises are called Easter Eggs (if not bugs!), and Easter is not far away, so maybe we might find out...

As it relies on the HW PCNT counters, it can go very very fast (MHz)
