Hey there, I'm trying to get this little rotary encoder to not be so glitchy and I'm at a loss. I've had the "best" luck through basic wiring (only pullup resistors on A/B), but it's still pretty finicky getting it to land on a number you want. Has anyone had any luck with them and what method did …

If you can dedicate two interrupts to be used by the rotary-encoder you can use the NewEncoder-library from user gfvalvo My experience so far: 100% reliable even with the bounciest mechanical switches rotary-encoders. [image] GitHub - gfvalvo/NewEncoder: Rotary Encoder Library Rotary E…

Thank you, very enlightening. That run time discrepancy may explain why I would get better results when I isolate the encoder code and it glitches again when I try and insert the same code back in my project code. I did try your code and wasn't able to get it working: (RIGHT TURN)-2, -1, 0, -1, 0,…

I tried your demo code and library on this encoder and I got the same terrible results: -1, 0, -1, -2, -3, -4, -3, -2, -3, -2, -1, 0, -1, 0, -1, 0, -1, -2, -1, -2, -3, -4, -3, -4, -3, -4, -5, -6, -5, -6, -5, -4, -5, -6, -7, -8, -9, -10, -11, -12, -13, -12, -11, -12, -13, -14, -13, -14, -13, -14, -1…

[image] jugglebug00: I'm thinking, between my apparent poor choice in hardware It would be very interesting to know which exact type of microcontroller you are using. Me personally those cheap KY-40 RE work pretty good with the "standard"encoder.h-library if the code is running on Arduino Un…

I have pretty good luck with just putting 0.1uF ceramic caps from the A, B and SW terminals to ground to do hardware debounce. Wire the commons to ground and the A,B and SW terminals to inputs set to pinMode INPUT_PULLUP.

[image] StefanL38: But very unreliable on faster microcontrollers like the ESP8266, ESP32 or teensy I found that using the Raspberry Pi Pico, than a simple 0.1uF (ceramic) to ground on all three signal wires was enough to get them to work reliably. But using an interrupt is a must. The KY-40…

Do keep in mind that the purpose of the tutorial was to illustrate that you don't need to debounce a rotary encoder. The code illustrates what I wanted to show but it is imperfect. The issue is you can get close to1kHz from a rotary encoder without much difficulty if you turn it fast enough. I think…

It's possible your encoders are so bad that they won't work well with anything. The state table method generally works very well, even with encoders that bounce a lot. But if the switches in the encoder continue to bounce long after they should have settled down, there may be no way to produce goo…
