Deckel Maho NC Integration

That's not how I would interpret the words into a circuit diagram.

Can you link to the original post? I can't find it.

That in the sketch is not what he is describing. It says to have 2 resistors in series between +3.3V and GND, use the middle of them as input/output.
Do that for both inputs ( total 4 resistors ).
I did not do the math, but it should be ok.

Like this:

Yup, that should do it.

And yep; you are correct! The circuit as show above is working fine.

Thanks for the help people.
