VFO Design with Adaptive Step Rate and Vernier Display

The encoder arrived today. The one I finally settled on is an optical encoder with push button. For the continuous tuning VFO I wanted an optical encoder without detent and push switch. This one is 64 ppr, which is in the range that should make the adaptive step control work smoothly without having to change the code too much.

It's not free spinning like a servo style incremental encoder, it has some rotational resistance so with the right size and weight knob it should be ok.

I purchased an ENS1J-B28 L00064 on Ebay a couple of weeks ago.
It was quite cheap, at least compared to new. And it was s'posed to be new old stock.
This one too is a 64PPR device. It has no detents or switch.
