帮我写一个步进电机控制带动皮带xy移动的代码

好的，以下是步进电机控制带动皮带xy移动的代码：

import RPi.GPIO as GPIO
import time
 
# 设置GPIO模式为BCM模式
GPIO.setmode(GPIO.BCM)
 
# 定义步进电机引脚
motor_pins = [17, 18, 27, 22]
 
# 定义步进电机驱动顺序
motor_seq = [[1,0,0,1],
             [1,0,0,0],
             [1,1,0,0],
             [0,1,0,0],
             [0,1,1,0],
             [0,0,1,0],
             [0,0,1,1],
             [0,0,0,1]]
 
# 设置引脚为输出，并初始化为LOW
for pin in motor_pins:
    GPIO.setup(pin,GPIO.OUT)
    GPIO.output(pin, 0)
 
# 定义步进电机前进和后退函数
def motor_forward(delay, steps):
    for i in range(steps):
        for j in range(8):
            for pin in range(4):
                GPIO.output(motor_pins[pin], motor_seq[j][pin])
            time.sleep(delay)
     
def motor_backward(delay, steps):
    for i in range(steps):
        for j in reversed(range(8)):
            for pin in range(4):
                GPIO.output(motor_pins[pin], motor_seq[j][pin])
            time.sleep(delay)
 
# 定义控制皮带移动函数
def move_xy(x_steps, y_steps, delay):
    # x轴步进电机前进
    motor_forward(delay, x_steps)
    time.sleep(0.5)
    # y轴步进电机前进
    motor_forward(delay, y_steps)
 
# 控制皮带移动
move_xy(100, 100, 0.01)
 
# 释放引脚
GPIO.cleanup()

注意：这段代码仅供参考，需要根据具体的硬件电路进行调整和修改。
