Multi Switch Shutdown Script!

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 :)

BiZzAr721

I never did get to learn how to compile like I wanted to. Is there something in a gpio-halt script that can manually edit after it is installed? I'm not even fully understanding how to change the call to script before compiling. Sorry for being a bother.

cyperghost

@BiZzAr721 You just change the line

(void)system("shutdown -h now");

to annother call. I would use annother script.

(void)system("/home/pi/RetroPie/shutdown.sh");

Then you create annother script /home/pi/RetroPie/shutdown.sh and make it executable with chmod +x /home/pi/RetroPie/shutdown.sh. Then you can nest any command as you like inside this. After this code change you compile as Adafruit descripes. I'm sure you do not need to stick to this specific C-program. The same can be achived in python.

Imho you can use multi_switch.sh --generic powerbtn=21 call to achive same funtion. But I can't test this. Please use sudo apt raspi-gpio before.

BiZzAr721

I created a fork of Adafruit-GPIO-Halt. I made the change to (void)system("/home/pi/RetroPie/shutdown.sh");

I'm confident I can compile it from there. Should I put a call to multi_switch.sh --generic powerbtn=21 in the script or should I call to it directly before compiling?
There is a call in rc.local to /usr/local/bin/gpio-halt 6 & (6 being the gpio pin used, which can be changed)
If I set it to gpio 2 SDA or gpio 3 SCL, arcade controls will not work. Maybe that explains why raspi-gpio causes loss of controls. (Is it possible to get raspi-gpio to not monitor those pins?)

cyperghost

@BiZzAr721 I think it works with multi_switch.sh --generic powerbtn=21 and you do not need the Adafruit-GPIO-Halt.

If you compile the source code now with your changes you can add ANY command to the script you've created. Then you can just add path/to/multi_switch.sh --es-poweroff

BiZzAr721

@cyperghost Looking forward to giving it a try this evening. I'll edit this post with the results.

EDIT:
I recompiled GPIO-Halt, and pointed the script to your script. It worked great!
@cyperghost I appreciate all I have learned from you since the OpenBOR days lol What you do here for the community is a beacon of your character. Not only are you always willing to help, but you also take the time to explain and help others improve their skills.

It may not be much, but I thought it to be rewarding to fork the Adafruit Gpio-halt git, and compile it (and have it work!).

Thanks!

cyperghost

@BiZzAr721 Thanks you for your kindly words but I also asked question regarding coding in the beginning and @meleu helped me a lot, too.

BiZzAr721

@cyperghost Is always great to have a community of likeminded people who share a common interest, be it skydiving, retro gaming, or whatever. You end up with a diverse group of people with various skills all sharing ideas & talents, which usually transcends beyond political or religious differences.
