Encoder trouble makes FM hard to control

MIDIbox FM
1

Hi guys, after 2 years i found some spare time and motivation to finish my FM.

Now i’ve a problem with the encoders. They are from AVI Showtech and are 24 step detented encoders. They seems to be glitchy and every step modify the counter of 4 steps or more. Even movin the knob up and down without doing another step makes the counter up or down.

Attacched there is a photo of the encoder and a video of the trouble.

Can you suggest me something to solve the problem?

Kisses

Well, the obvious would be: get another encoder!

Actually, I sometimes have similar problems with the sammichFM such that I have wondered if it was a software thing?

No, it’s now SW issue.

But this can happen if you swapped the connections between the 3 encoder pins!

Some encoders have ground at the middle pin, some others at the left pin.

Just try it! :slight_smile:
