Question

第一篇文章。我有一个搜索周围，没有找到很多关于此的信息，希望有人在这里可以提供帮助。

对于背景，我正在建立一个进站计时系统，以便在比赛期间使用他们的轮枪/反应来辅助机械师。 PIt Stop Rig。希望你能在图片中看到，有四个轴，每个都有一个LED，每个都切换。

我正在编写一个脚本来运行一个基本的反应计时器，使用Rpi，Piface Digital 2并用Python驱动它。我有第一次迭代工作，因为它读取数字输入，并驱动数字输出。我现在想做到这一点，它通过5次运行scriput，读取数字输入并将它们存储在变量中。如果有人可以使用Python，我会非常感激。

    # Pit Stop Reaction Timer

    from time import sleep
    from timeit import default_timer as timer
    import random
    from random import randrange, uniform
    import pifacedigitalio as pifacedigital
    import sys

    pifacedigital.init()
    leds = [1, 2, 3, 4]
    randomNumber1 = [0, 3 , 2, 1, 1, 2, 3, 0, 0, 2, 3, 1, 1, 3, 0, 2]
    randomNumber2 = [2, 4, 6, 8, 4, 3, 8, 12, 10, 11, 9, 8, 6, 7, 10, 5]
    randomLED = random.choice(randomNumber1)
    randomFlash = random.choice(randomNumber2)

    sleepTime = 0.1  # the time in seconds
    rounds = 8
    button4 = 0
    button5 = 1
    button6 = 2
    button7 = 3



   def ledFlash(times, interval):
       i = 0
       # repeat times times ...
       while i < times:
           # turn on LED 1 to 4
           for led in leds:
           pifacedigital.digital_write(0, 0)
           pifacedigital.digital_write(1, 0)
           pifacedigital.digital_write(2, 0)
           pifacedigital.digital_write(3, 0)
           sleep(interval)

          # turn off LED 0 to 4 one at a time with interval intervals ...
           for led in leds:
           pifacedigital.digital_write(0, 1)
           pifacedigital.digital_write(1, 1)
           pifacedigital.digital_write(2, 1)
           pifacedigital.digital_write(3, 1)
           sleep(interval)

       i += 1


     print("Menu:")
     print("=====")
     print("External Button: Start Pit Stop Sim")
     print()
     print("Select the correct hub with the gun to stop the timer")

     while True:
       if pifacedigital.digital_read(0):
       ledFlash(randomFlash, sleepTime)
       pifacedigital.digital_write(randomLED, 0)
       start = timer()
       print("Random LED result", randomLED)
       print("Random number of LED flashes result", randomFlash)
    elif pifacedigital.digital_read(4) and button4 == randomLED:
       end = timer()
       print(end-start)
       sys.exit()
    elif pifacedigital.digital_read(5) and button5 == randomLED:
       end = timer()
       print(end-start)
       sys.exit()
    elif pifacedigital.digital_read(6) and button6 == randomLED:
       end = timer()
       print(end-start)
       sys.exit()
    elif pifacedigital.digital_read(7) and button7 == randomLED:
       end = timer()
       print(end-start)
       sys.exit()

任何关于使用循环来使其迭代5次的指针，以便我可以测量并取平均值。

非常感谢

乔。
