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()
