Rotary Encoder On Rpi Pico Moderators: adafruit_support_bill, adafruit

[Jnorris03]

It looks like the rotaryio module isn't included in the Pico port? Is there any easy way to import it? What is the best way to implement an encoder without it? I've tried bringing the pulses in as normal inputs, but I don't think I can process them fast enough because the state changes seem to be erratic.

I believe it has been added to the newest build, but beware not everything maybe stable.

Hmm... Ok I'll check that when I get home. I thought I had the latest version, but maybe not.

So now I get the error "pull masks conflict with direction masks" but I can't find any documentation on that error. I assume it because I was using the pins for something else already and they need to be released?

Edit: I got it working with two other pins; so it must be something with certain pins on the Pico port.

Which two pins failed originally? We may have a math error internally.

I was originally trying to us GP14 and GP15. I got it working on GP16 and GP17.

I had the same issue with the RC0 build. I was also using GP14 & GP15.

I'll try moving the pins later.

I have just tried this with the 6.2 release version of CircuitPython and the code fails with an error on GP14 & GP15. It does run on GP16 and GP17 but does not work.

Time to have a look at what the hardware is doing.

GP15 is not recommended for use - it can interfere with USB, just use any other pins :)

How about changing the exception to something meaningful. The message pull masks conflict with direction masks is really not very helpful.
