使用 easydriver 和 raspberry pi 控制步进电机

Question

我最近开始了我的 Rpi 项目。
我需要一些帮助或建议来调整我的代码。

我有一个（Pi，+ easydriver V4.4，+ nema 17 步进电机）
使用 BCM 布局

我需要一个无限嵌套循环，有一个区间@

# Do some steps.
for i in range(200):#800 == full rotation
stepper.step()

我希望我的步进器步进 200 步，然后停止 0.1 秒，然后再步进 200 步等（无限循环）

感觉自己像个傻瓜……在我睡觉的时候发生了异常！ 这就是我创建循环的方式：

loopinfinity = 1
# Do some steps.(800) full revolution
def step_motor():
  for i in range(120):
    stepper.step()

while loopinfinity > 0:
  try:
     step_motor()
     time.sleep(0.07) #this is in seconds
  except KeyboardInterrupt :
     loopinfinity -=1
     print("stopped")
