Encoder problem #1

Closed buelldozer closed 4 years ago

buelldozer commented 4 years ago

First of all, superb project! When connecting an encoder as describe in documentation, buttons are pressed every two encoder steps and not every step.

Hi, please specify which encoder do you use. Some types of encoders have 1 pulse for 2 detents (for example PEC11R-4220F-S0012 has 12 pulses for 24 detents)

Hi, I use Alps EC11B encoder (https://www.mouser.fr/datasheet/2/15/alps_alps-s-a0008379064-1-1733314.pdf)

According to this documentation your encoder has 1 pulse per 2 detents as i mentioned before. If you need 1 pulse per detent you have to use another encoder

OK, thanks for your fast reply! Could be nice to have the feature to manage rotary encoders with twice detents, because most of low PPR encoders ( like 8) have always twice detents.

vostrenkov commented 4 years ago

You mean encoders with 2 or 4 pulses per detention?

buelldozer commented 4 years ago

yes, at least encoders with 2 pulses per detention, as they are more common

vostrenkov commented 4 years ago

This is possible

vostrenkov commented 4 years ago

v1.6.0 added new modes for encoders, so you can select encoder reading resolution
