libreELEC python script
« on: August 03, 2017, 10:17:16 AM »
The "Raspberry Pi Tools" addon is required.

Place this script in /storage/.config/shutdownirq.py
Modify the GPIO pins to your own needs
chmod 755 /storage/.config/shutdownirq.py

Code: [Select]
#!/usr/bin/python
# ATXRaspi interrupt based shutdown/reboot script
# Script based on Tony Pottier, Felix Rusu
# modified by Juergen Schweighoer
import sys
sys.path.append("/storage/.kodi/addons/virtual.rpi-tools/lib")
import RPi.GPIO as GPIO
import os
import time

GPIO.setmode(GPIO.BCM)

pulseStart = 0.0
REBOOTPULSEMINIMUM = 0.2 #reboot pulse signal should be at least this long (seconds)
REBOOTPULSEMAXIMUM = 1.0 #reboot pulse signal should be at most this long (seconds)
SHUTDOWN = 6 #GPIO used for shutdown signal
BOOT = 5 #GPIO used for boot signal

# Set up GPIO 5 and write that the PI has booted up
GPIO.setup(BOOT, GPIO.OUT, initial=GPIO.HIGH)

# Set up GPIO 6  as interrupt for the shutdown signal to go HIGH
GPIO.setup(SHUTDOWN, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)

print "\n=========================================================================================="
print "   ATXRaspi shutdown IRQ script started: asserted pins (",SHUTDOWN, "=input,LOW; ",BOOT,"=output,HIGH)"
print "   Waiting for GPIO", SHUTDOWN, "to become HIGH (short HIGH pulse=REBOOT, long HIGH=SHUTDOWN)..."
print "=========================================================================================="
try:
while True:
GPIO.wait_for_edge(SHUTDOWN, GPIO.RISING)
shutdownSignal = GPIO.input(SHUTDOWN)
pulseStart = time.time() #register time at which the button was pressed
while shutdownSignal:
time.sleep(0.2)
if(time.time() - pulseStart >= REBOOTPULSEMAXIMUM):
print "\n====================================================================================="
print "            SHUTDOWN request from GPIO", SHUTDOWN, ", halting Rpi ..."
print "====================================================================================="
os.system("poweroff")
sys.exit()
shutdownSignal = GPIO.input(SHUTDOWN)
if time.time() - pulseStart >= REBOOTPULSEMINIMUM:
print "\n====================================================================================="
print "            REBOOT request from GPIO", SHUTDOWN, ", recycling Rpi ..."
print "====================================================================================="
os.system("reboot")
sys.exit()
if GPIO.input(SHUTDOWN): #before looping we must make sure the shutdown signal went low
GPIO.wait_for_edge(SHUTDOWN, GPIO.FALLING)
except:
pass
finally:
GPIO.cleanup()


Place this script in /storage/.config/autostart.sh
chmod 644 /storage/.config/shutdownirq.py

#!/bin/bash
