didnt work for me…obliviously i changed the pin numbers
This work! You should press for 3 seconds the button to shutdown the system
import RPi.GPIO as GPIO
import time
import os
stopcount = settingcount = 0
GPIO.setmode(GPIO.BCM)
GPIO.setup(10, GPIO.IN,pull_up_down=GPIO.PUD_UP)
while True:
#print GPIO.input(10)
if (GPIO.input(10) == False):
stopcount = stopcount + 1
#print stopcount
if stopcount == 30: # 3 secondi di pressione e si spegne
#print 'reboot'
os.system("sudo shutdown -h now")
else: # means GPIO10 == True
#print 'stopcount reset'
stopcount = settingcount = 0
time.sleep(0.1) # is sleep(1) ok or does it need to be shorter. for example sleep(0.1)I might have missed something, I didn’t post the whole code, I just pulled out part on my code dealing with shutdown and made one edit to simplify it. The edit is likely what messed it up. The full file is as follows and the shut down works. It’s delayed until the end of my message. I think you’ll see why I didn’t post the full file, there is a lot going on.
