Rotary support request

[tuomas]

Hi Dirk!

Basically it seems like the "Knitter" encoding happens to work for some weird reason for me, and for Claudio, the "ALPS" mode seems to do it.

What seems to happen is that the encoder sends +-++-++-++... which, when you sum them up, makes "+++" - just a lot of back-and-forth moving.

The Knitter mode with a phase-shifted rotary seems to work a lot better here - good enough that I plan on using them (no jerking at all), I am very surprised. Maybe it is some strange timing that just happens to go right here, but I wired a panasonic "phase shifted" rotary and configured it as "knitter" and hooked it to the QNH knob - and it works very well.

I am kind of surprised that it accidentally works..

Maybe the thing could be made to work by just filtering out the certain "++-++-++-" -pattern? Havent got a scope so I dont know exactly what happens, but it is pretty funny that it works.

I understand the issues for decoding them, so I trust what you say, I dont know much about this stuff anyway - and there's the "REDEC" circuit anyway which is told to work.
