Скачать или смотреть #96 Rotary Encoder Update - Stepless & Software Debounced

A couple of recent comments on a previous video #19 (Rotary Encoders) made me think and ponder. So here's an update that looks at both the original sketch and stepped Rotary Encoder and also at a newer detentless (stepless) one, with the problems it potentially presents.

We also consider how best to debounce the signal in software and what happens if you change the way I originally did it with a Real World example of my car radio - yes, really!

I've included a link to a GitHub repository with the simple test sketches I used just so you can grab them and play about with them yourself, along with links to the stepless Rotary Encoder (rather more than I'd want to pay but it was supplied by a local supplier rather than a Far Eastern warehouse so would be more, of course).

NOTE: The PEC-016 part number convention is that the second digit determines whether it is stepped or not.
Eg: PEC16-4020F-N0024 - it's the 4020F that is important - the second digit here (0) means STEPLESS
The next part, N0024 determine whether a SWITCH pin is included (N=NO, S=YES) and the 24 shows how many steps per revolution
