@teastain Thank you - I had misunderstood what the Z was for. Because on the ky040 the middle pin is for the "switch" functionality (i.e. pushing down on the encoder) I assumed it was for this. I realise now that I need to treat that as a button and take it off to a different pin, which I know how to do.

Thanks for your help!

Hi all

I’ve successfully got a KY040 rotary encoder working with the m5Stack ext- encoder unit.

I can register rotations but the part I haven’t made work is the push button - which is a straightforward contact button

There is an input for it on the ext encoder marked as Z but I can’t find any documentation on how I read this button and there seem to be no functions in the class to handle it.

Does anyone have any idea how I handle this?

Thanks in advance
