Hello, I was looking at this ULR: http://en.nanotec.com/steppermotor_animation.html
And I wonder if the library uses the microstep or the other principle for 4-way stepper motor control?
Can anyone explain to me which way the library uses please? The microstep way seems a lot more advanced and I suspect it is more efficient.
Regards,

Micro stepping (beyond half stepping that is) is a function of the hardware driver not the software. This is because it has to give a varying current into the coils, this varies over a full step cycle.
