Stepper_UNIPOLAR

This class provides a generic driver for use with any center-tapped unipolar stepper motor. Requires the use of a driver board that can convert the low-voltage/low-current digital signals from 4 pins on the ESP32 to higher-voltage/higher-current outputs suitable for direct connection to the two phases (A and B) of each coil (1 and 2) in the stepper motor.

The Stepper_UNIPOLAR class includes the following constructors:

  • Stepper_UNIPOLAR(int coil1A, int coil1B, int coil2A, int coil2B)

    • controls the driver board using only 4 digital pins from the ESP32, where the parameters specify the pin numbers. Supports the following step type modes:

      • FULL_STEP_ONE_PHASE
      • FULL_STEP_TWO_PHASE
      • HALF_STEP

❗Note: This class does not support a short brake state. Calls to the brake() method, as well as setting the endAction parameter in the move() and moveTo() methods to StepperControl::BRAKE have no effect on the motor driver.
