ESP32 Forum

I work on a project which is supposed to use 3 standard EC11 rotary encoders. I tried couple available libraries however encoders skip the steps or don't recognize rotation properly.
What is the best way to automate and simplify rot. encoding so there is no issues as above?
Is there maybe external circuit translating multiple encoders or some tricky wiring that works best?

Thanks

The ESP32 has a pulse counter, which can be configured to do up/down counting in the way you'd expect when using a rotary encoder.

Looks like a very good api ! I will try it
Great thanks!

Just a small update - tested pcnt example from idf and it works amazingly well with normal EC11 encoder even without changing the parameters in the example. It is very convenient tool and saves a lot lot of coding work )
It has built in thresholds, direction and even events triggered at certain counter values!

Hi,
Here there is a project that can solve your problem: https://hackaday.io/project/27611-i2c-encoder

Hi! Where did you find this example?
