Let's put workarounds for too low resolution aside for now, please. External ADCs, 2-ton magnets, 13.7 deg potentiometers, epicyclic gearing... I would really appreciate if either of you could simply explain to me why. MMJoy2 takes a valuable resource which is the resolution of 1024 steps and wastes it by spreading it over 270 degrees of potentiometer rotation range. Why is that?

Especially that both the Allegro A-series as well as potentiometers are analog devices i.e. providing infinite resolution. The resultant resolution in an actual application is only limited by controller used.

But calibration only works by picking a part of the 1024 range, right? So for a potentiometer granted 1024 steps for the entire 270 deg I only put e.g. 400/450/500 (min/center/max) in the calibration fields.

I do know how ADCs work but not much beyond that.
