Thread: Mouse + Encoder Troubles (detent num. difference)

Hi! I've been lurking here and reading about rotary encoders, so I decided to try and build a custom knob with one. It kinda worked, so here I am asking for help!

I got an old Microsoft PS/2 wheel mouse (with ball) and attached an alps encoder from a broken monitor I had (it had a wheel that could be turned and pushed to configure it).
After replacing the scroll wheel encoder with the one from the monitor, it was recognized, and I was able to use it like a regular scroll wheel...almost.
The problem is that the encoder only works properly if I don't move it too fast.
Moving it at a reasonably quick rate results in a sort of jittering -- like if I was moving the wheel up and down quickly. Sometimes it goes backwards, too

(edit: I now know that the term is called 'backspin')

I think this has something to do with the resolution of the new encoder being much greater than the old one (many more detents).

How do I fix it? Is there any way to only have it read every other click or something like that?

Help is appreciated


EDIT:
Clarification: Switching the wires won't work, I tried. The encoder functions perfectly as long as I turn it relatively slowly.
