Hi Jay,

I tried many ways, also interrupts. But only on the described solution I get always good results.
Also its very fast (only some CJNE).

Also it make no sense to increase the resolution:
Yes, you can hold the knob in an intermediate state, but if you remove your fingers, the knob flips to the nearest full step.
Its fully different to rotary encoders on machines. But then I suggest such with optical sensors, since then no debouncing was needed.
