It does work:

Stepper Driver with Quadrature from Stepper.h or Encoder

A STEP+DIR stepper driver can be driven with the quadrature signal from an encoder, or with the quadrature signal from the Arduino Stepper.h library Based on the discussion in Change stepper dir according to predifined analog input value - #22 by DaveX I wired a quadrature encoder directly to a stepper driver to drive a stepper motor in this Wokwi simulation: [image] It uses no real code because 2 square waves in quadrature from the encoder works fine to drive a STEP+DIR stepper driver: /…

But it is 1/4 the speed/4x the steps, since you have to cycle all the way through a quadrature cycle for every step.

There are much better options than Stepper.h.
