# You can use any available GPIO pin on both a microcontroller and a Raspberry Pi.
# The following pins are simply a suggestion. If you use different pins, update
# the following code to use your chosen pins.

# To use with a Raspberry Pi:
coils = (
    digitalio.DigitalInOut(board.D18),  # A1
    digitalio.DigitalInOut(board.D17),  # A2
    digitalio.DigitalInOut(board.D27),  # B1
    digitalio.DigitalInOut(board.D22),  # B2
)

for coil in coils:
    coil.direction = digitalio.Direction.OUTPUT

motor = stepper.StepperMotor(coils[0], coils[1], coils[2], coils[3], microsteps=None)

for step in range(STEPS):
    motor.onestep()
    time.sleep(DELAY)

for step in range(STEPS):
    motor.onestep(direction=stepper.BACKWARD)
    time.sleep(DELAY)

for step in range(STEPS):
    motor.onestep(style=stepper.DOUBLE)
    time.sleep(DELAY)

for step in range(STEPS):
    motor.onestep(direction=stepper.BACKWARD, style=stepper.DOUBLE)
    time.sleep(DELAY)

for step in range(STEPS):
    motor.onestep(style=stepper.INTERLEAVE)
    time.sleep(DELAY)

for step in range(STEPS):
    motor.onestep(direction=stepper.BACKWARD, style=stepper.INTERLEAVE)
    time.sleep(DELAY)
