After spending a lot of time calibrating the hall potentiometer, I cannot remove dead space at both ends of the lever travel.
Surprisingly, calibration by itself does not correct the fact that the pot does not truly provide a 0-5 V range.
Even if I try to "trick" the travel of the lever by not full moving from stop to stop during calibration, the dead zone still persist.
Is the solution only through gear ratio?
At this point I cannot say that a hall pot is a good solution for precise end to end throttle control.
Even changing resolution in mmjoy does not alter this phenomenon.
Hopefully, someone has a good calibration technique to overcome this issue.
