我一直在努力使用一个脚本,将Pi的BCM引脚17,27和10打开1秒,然后关闭1秒,依次100次.当我运行脚本时,LED1将打开,然后它会关闭,程序会因此错误而关闭:

RuntimeError: Please set pin numbering mode using     GPIO.setmode(GPIO.BOARD) or GPIO.setmode(GPIO.BCM)

import RPi.GPIO as GPIO
import time

LED1 = 17
LED2 = 27
LED3 = 10

GPIO.setmode(GPIO.BCM)

def LED1Blink():
        GPIO.setup(LED1, GPIO.OUT)
        GPIO.output(LED1,True) 
        time.sleep(1)  
        GPIO.output(LED1,False)
        time.sleep(1)
        GPIO.cleanup()
