我原來是寫單片機程式的，由于要設計一個樹梅派的電路板，參考別人的一段程式，但是在安裝這個腳本的時候提示錯誤，SyntaxError: EOL while scanning string literal
，問題就在第一行的單引號和倒數第三行的單引號，幫忙看看這兩個單引號是不是語法錯誤，但這個腳本是已經量產的產品上用的：
echo 'import RPi.GPIO as GPIO
import os
import sys
import time
GPIO.setmode(GPIO.BCM)
pulseStart = 0.0
SHUTDOWN = 24 #pin 18
BOOT_OK = 23 #pin 16
REBOOTPULSEMINIMUM = 0.2 #reboot pulse signal should be at least this long
REBOOTPULSEMAXIMUM = 0.6 #reboot pulse signal should be at most this long
print ("\n=====================================\n")
print ("== ATX-PSU_startup: Initializing GPIO")
GPIO.setup(SHUTDOWN, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
GPIO.setup(BOOT_OK, GPIO.OUT, initial = GPIO.HIGH)
try:
while True:
print ("\n== Waiting for shutdown pulse\n")
GPIO.wait_for_edge(SHUTDOWN, GPIO.RISING)
print ("\nshutdown pulse received\n")
pulseValue = GPIO.input(SHUTDOWN)
pulseStart = time.time()
pinResult = GPIO.wait_for_edge(SHUTDOWN, GPIO.FALLING, timeout = 600)
if pinResult == None:
GPIO.output(BOOT_OK, GPIO.LOW)
os.system("sudo poweroff")
sys.exit()
elif time.time() - pulseStart >= REBOOTPULSEMINIMUM:
GPIO.output(BOOT_OK, GPIO.LOW)
os.system("sudo reboot")
sys.exit()
if GPIO.input(SHUTDOWN):
GPIO.wait_for_edge(SHUTDOWN, GPIO.FALLING)
except:
pass
finally:
GPIO.output(BOOT_OK, GPIO.LOW)
GPIO.cleanup()
