Multi Switch Shutdown Script!

AndersHP

Hi, I kind of hijacked another thread regarding Pegasus, but thought I would ask here instead.

I'm not using a RetroFlag unit, but a Kite Circuit Sword from Sudomod.com

I'm unsure if my shutdown script, the cs_shutdown.sh file in /opt/ folder, does something special that can harm the safe-shutdown process if not built into another script, e.g. your Multi Switch Script. My file looks like this (also mentions a shutdown file?):

#!/bin/bash

# Get ES pid
ES_PID=`pidof emulationstation`

if [[ $ES_PID != "" ]] ; then

  echo "ES_PID: $ES_PID"

  # Touch the shutdown file
  touch /tmp/es-shutdown
  chown pi:pi /tmp/es-shutdown

  # Tell ES to terminate
  kill -s SIGTERM $ES_PID

  echo "ES has been asked to shutdown"

else

  echo "Could not find ES PID ($ES_PID)"
  sudo shutdown -h now &

fi

Could I just delete this file, and install your Multi Switch Script with the modifications that @SinisterSpatula mentions? Or would I miss something? How much is this solely for RetroFlag builds?

For instance: The RetroFlag is a Pi Zero right? My Circuit Sword is a CM3+ module (not GPIO based, but basically a RPi 3+).

How can I tell if the script works as intended apart from the screen going black?

@AndersHP Try replacing

ES_PID=`pidof emulationstation`

with

ES_PID=`pidof pegasus-fe`

or what's the actual process name of the Pegasus front-end. The rest of the script should be the same.

AndersHP

@mitu OK thanks, but can I see somehow if everything is working as planned - apart from the obvious thing that Pegasus should quit?

mitu

@AndersHP The script you posted does nothing more than stopping Pegasus and shutting down, so if comment out the shuttind down part you can check by seeing if the front-end stops.

AndersHP

Did the pidof pegasus-fe trick and pegasus quits to terminal now.
But the machine doesn't power off now...?

cyperghost

@AndersHP your script will just close Pegasus and that's all. you should add a shutdown command to completly shutdown your system.

your (easy) script would more look like...

#!/bin/bash
PEGASUS_BIN="pegasus-fe"
if [[ -n $(pidof $PEGASUS_BIN) ]] ; then
    killall -w $PEGASUS_BIN
fi
sudo poweroff

Much cleaner and more generic than the original one.

If you want the proper exit of all emulators then use this script...

#!/bin/bash
PEGASUS_BIN="pegasus-fe"
if [[ -n $(pidof $PEGASUS_BIN) ]] ; then
    bash multi_switch.sh --closeemu
    killall -w $PEGASUS_BIN
fi
sudo poweroff

AndersHP

But the script literally powered off my Gameboy before I did the ES -> Pegasus change...?

cyperghost

@AndersHP But this script does behave like your original one. If you are in terminal and type sudo poweroff does then your mashine power off completly?

The difference between ES and Pegasus is, that ES uses a "helper" script for shutdown status, therefore the touch-thing.

I think you should be more specific for your setup, which additional scripts are running, how did you install them.....

AndersHP

I changed to the above mentioned script, and it does quit and then shutdown. Thanks for the help - will try the Multi Switch script next.

cyperghost

@AndersHP Don't forget to setup correct path to to script if you call bash multi_switch --closeemu - I know it's sometimes hard to remember doing the things correctly :)

@cyperghost Id like to use your multi shotdown script with my new argon one case because their script is much less functional than yours. Their argononed.py script looks like this:

import smbus
import RPi.GPIO as GPIO
import os
import time
from threading import Thread
rev = GPIO.RPI_REVISION
if rev == 2 or rev == 3:
	bus = smbus.SMBus(1)
else:
	bus = smbus.SMBus(0)
GPIO.setwarnings(False)
GPIO.setmode(GPIO.BCM)
shutdown_pin=4
GPIO.setup(shutdown_pin, GPIO.IN,  pull_up_down=GPIO.PUD_DOWN)
def shutdown_check():
	while True:
		pulsetime = 1
		GPIO.wait_for_edge(shutdown_pin, GPIO.RISING)
		time.sleep(0.01)
		while GPIO.input(shutdown_pin) == GPIO.HIGH:
			time.sleep(0.01)
			pulsetime += 1
		if pulsetime >=2 and pulsetime <=3:
			os.system("reboot")
		elif pulsetime >=4 and pulsetime <=5:
			os.system("shutdown now -h")
def get_fanspeed(tempval, configlist):
	for curconfig in configlist:
		curpair = curconfig.split("=")
		tempcfg = float(curpair[0])
		fancfg = int(float(curpair[1]))
		if tempval >= tempcfg:
			return fancfg
	return 0
def load_config(fname):
	newconfig = []
	try:
		with open(fname, "r") as fp:
			for curline in fp:
				if not curline:
					continue
				tmpline = curline.strip()
				if not tmpline:
					continue
				if tmpline[0] == "#":
					continue
				tmppair = tmpline.split("=")
				if len(tmppair) != 2:
					continue
				tempval = 0
				fanval = 0
				try:
					tempval = float(tmppair[0])
					if tempval < 0 or tempval > 100:
						continue
				except:
					continue
				try:
					fanval = int(float(tmppair[1]))
					if fanval < 0 or fanval > 100:
						continue
				except:
					continue
				newconfig.append( "{:5.1f}={}".format(tempval,fanval))
		if len(newconfig) > 0:
			newconfig.sort(reverse=True)
	except:
		return []
	return newconfig
def temp_check():
	fanconfig = ["65=100", "60=55", "55=10"]
	tmpconfig = load_config("/etc/argononed.conf")
	if len(tmpconfig) > 0:
		fanconfig = tmpconfig
	address=0x1a
	prevblock=0
	while True:
		temp = os.popen("vcgencmd measure_temp").readline()
		temp = temp.replace("temp=","")
		val = float(temp.replace("'C",""))
		block = get_fanspeed(val, fanconfig)
		if block < prevblock:
			time.sleep(30)
		prevblock = block
		try:
			bus.write_byte(address,block)
		except IOError:
			temp=""
		time.sleep(30)
try:
	t1 = Thread(target = shutdown_check)
	t2 = Thread(target = temp_check)
	t1.start()
	t2.start()
except:
	t1.stop()
	t2.stop()
	GPIO.cleanup()

I tried changing the os.system to os.system("bash /path/to/multi_switch/multi_switch.sh --es-poweroff")like you suggested an earlier time that you helped me but then the reboot and shutdown dont seem to work anymore (I did use the correct path). Obviously I am missing something. I appreciate any guidance you could provide.

@quicksilver It should work with the commands you've posted .... but you've to take care about python idents. Is there an error output?

if true:
print "This won't work"

if true:
    print "This will work"

quicksilver

@cyperghost Since you said it should work it made me think of what I might have messed up. Looks like I forgot to give proper permissions to the multi_switch.sh file. Metadata is now saving properly. Thanks for your assistance!

cyperghost

I see no reason for a downvote here.
Maybe the the one who downvoted @quicksilver can explain?

quicksilver

@cyperghost It's cool, it could have been accidental. And if not, I'm not one who cares much about fake internet points. I'm just happy I got it working. I now have your script setup on 3 different style cases!

AndersHP

I upvoted the post, so now it's back to 0 ;-)

Rion

@cyperghost Is it possible to make this work with the Argon One case?

quicksilver

@Rion scroll up a few posts ;)

Hello @cyperghost! Hope all has been well, or as well as it can be with this COVID-19 paranoia. I decided to make a mini arcade using an AdaFruit Arcade Bonnet and a Raspberry Pi 3 B+. I am using a generic momentary pushbutton. I can not get the shutdown script AND the arcade bonnet controls to work at the same time. It seems having raspi-gpio installed blocks the controller inputs (which are mapped to keyboard buttons). Key presses work on a keyboard but not while passing through the arcade bonnet.

The arcade bonnet has breakouts to gpio pins. I tried GPIO 3, which is used by the arcade hat, but I also tried other GPIO pins that are not used by the hat. Here is a link to info and pictures of the board.

During install there is an option to install a gpio-halt utility. I've tried both with and without to no avail. I uploaded the contents of the arcadebonnet.pyand rc.local files. Here is the Adafruit-GPIO-Halt git.
arcadebonnet.py
rc.local

I am wondering if it could be possible to redirect gpio-halt to your shutdown script. I just flashed an SD card with a clean retropie image, so I can start again with a new install.
Thanks, and stay well.

cyperghost

@BiZzAr721 Yes ...
https://github.com/adafruit/Adafruit-GPIO-Halt/blob/master/gpio-halt.c#L261
change here the call to script and then compile.

All is well, thank you :)
