Linux 步进电机驱动代码示例

很抱歉，根据您提供的引用内容，似乎与Linux步进电机驱动代码示例无关。但是，我可以为您提供一个Python步进电机驱动代码示例。

步进电机驱动代码示例：

import RPi.GPIO as GPIO
import time

# 设置GPIO模式为BCM
GPIO.setmode(GPIO.BCM)

# 定义引脚
IN1 = 17
IN2 = 18
IN3 = 27
IN4 = 22

# 设置引脚为输出
GPIO.setup(IN1, GPIO.OUT)
GPIO.setup(IN2, GPIO.OUT)
GPIO.setup(IN3, GPIO.OUT)
GPIO.setup(IN4, GPIO.OUT)

# 步进电机正转函数
def forward(delay, steps):
    for i in range(0, steps):
        setStep(1, 0, 0, 1)
        time.sleep(delay)
        setStep(0, 1, 0, 1)
        time.sleep(delay)
        setStep(0, 1, 1, 0)
        time.sleep(delay)
        setStep(1, 0, 1, 0)
        time.sleep(delay)

# 步进电机反转函数
def backward(delay, steps):
    for i in range(0, steps):
        setStep(1, 0, 1, 0)
        time.sleep(delay)
        setStep(0, 1, 1, 0)
        time.sleep(delay)
        setStep(0, 1, 0, 1)
        time.sleep(delay)
        setStep(1, 0, 0, 1)
        time.sleep(delay)

# 步进电机控制函数
def setStep(w1, w2, w3, w4):
    GPIO.output(IN1, w1)
    GPIO.output(IN2, w2)
    GPIO.output(IN3, w3)
    GPIO.output(IN4, w4)

# 步进电机正转
forward(0.005, 512)

# 步进电机反转
backward(0.005, 512)

# 清理GPIO引脚
GPIO.cleanup()
