Python驱动tb6600

以下是Python驱动tb6600的示例代码，需要使用RPi.GPIO库和time库：

import RPi.GPIO as GPIO
import time

# 定义引脚
DIR = 20   # 方向引脚
STEP = 21  # 步进引脚
CW = 1     # 顺时针方向
CCW = 0    # 逆时针方向
SPR = 200  # 步数/转

# 设置GPIO模式
GPIO.setmode(GPIO.BCM)
GPIO.setup(DIR, GPIO.OUT)
GPIO.setup(STEP, GPIO.OUT)

# 设置电机方向
def set_direction(direction):
    if direction == CW:
        GPIO.output(DIR, GPIO.HIGH)
    elif direction == CCW:
        GPIO.output(DIR, GPIO.LOW)

# 步进电机旋转
def step(step_count, delay, direction):
    set_direction(direction)
    for i in range(step_count):
        GPIO.output(STEP, GPIO.HIGH)
        time.sleep(delay)
        GPIO.output(STEP, GPIO.LOW)
        time.sleep(delay)

# 旋转指定角度
def rotate_degree(degree, direction):
    step_count = SPR * degree / 360
    delay = 0.005
    step(step_count, delay, direction)

# 旋转指定步数
def rotate_step(step_count, direction):
    delay = 0.005
    step(step_count, delay, direction)

# 释放GPIO资源
def cleanup():
    GPIO.cleanup()

# 示例：顺时针旋转90度
rotate_degree(90, CW)

# 释放GPIO资源
cleanup()
