  各位大佬，能否帮忙看下这个GPIO 输入问题。
  from periphery import GPIO
  import time
  
  Write_Pin = 55
  Read_Pin = 54
  
  Write_GPIO = GPIO(Write_Pin, "out")
  Read_GPIO = GPIO(Read_Pin, "in")
  
  i = 1
  try:
  while True:
  try:
  #Write_GPIO.write(True)
  #pin_state = Read_GPIO.read()
  #print(f"Pin state: {pin_state}")
  
  #Write_GPIO.write(False)
  pin_state = Read_GPIO.read()
  print(f"i=%d Pin state: {pin_state}"%i)
  
  time.sleep(1)
  
  i = i+1
  
  except KeyboardInterrupt:
  Write_GPIO.write(False)
  break
  
  except IOError:
  print("Error")
  
  finally:
  Write_GPIO.close()
  Read_GPIO.close()
