3-phase motor such as common HDD or FDD motor
Note: tie common wire LOW, or invert control signals and tie common to +V

interrupt() method allows external user code to interrupt long-running otherwise-blocking while() loop in
void Stepper::step(int steps_to_move)

yield() in same while loop avoids WDT-timeout crashes on some controllers, such as Heltec's wifi kit 32

-------------------------------[ outline future example ]---------------------------------

  • Example for three-phase motor, using these changes to follow, by simplification of
    this code which currently also uses OLED display on wifi kit 32.
  • Button-press interrupt handler calls Stepper::interrupt() which sets flag that will stop
    the long-running while() loop in Stepper::step()
  • Note: images.h contains my xbm logo, displayed on OLED initialization

Added example 3-phase pot-adjustable-speed, interruptible stepper in folder
"stepper_3ph_knob_interrupt_oneRevolution"
