METADATA not saving - Favorites will never remain tagged

cyperghost

@julenvitoria Thanks for the headup. As I wrote this is just a basic script! meleu is the RegEx wizard out here. I changed codebox.... please try again.
I added emupid="$(pgrep -f "$emucall" | tr '\n' ' ')" pkill -P "$(echo $emupid | tr ' ' ',')"
PS: That are the outfindings of @meleu

I'm working on annother emulator detection - Shutdown script some input for better emulator detection

The errors @Semper-5 descripes are caused because these "empty" lines contain Carriage Return (CR) character (0x0D, \r) ... Windows uses linefeed (LF) and carrige return (CR) for creating a new line.

Hi! I tried your new code but don't work with pifba nor mame4 all. However it worked with pcsx-rearmed emulator. I tried kill -9 "$emupid" and then it works. I dont know if it is advisable or not to do this. If you know any other way I would appreciate it.

Thanks!

Really don't know why this is happening. I just copied some text parts.
But you may test this script here, please?
All you have to do is to copy from textbox into a bashfile. Maybe emu_shutdown.sh, make it executable with chmod +x emu_shutdown.sh and execute it via SSH if an emulator is running?

Maybe you will get better results then? It will only terminate emulators, not more not less.

julenvitoria

@cyperghost Hi, I tried your emulator detector too and the result was the same more or less. There were some emulators that dont stop... If you prefer I could write you throug the other thread.

cyperghost

@julenvitoria Thanks! You are right the signal levels are ignored by some emulators.
I would suggest to use kill -9 <PID>

I will update both scripts. So you see - once again something new explored .... ;)

Ok, so no errors to report. But the power switch doesn't work now.
I temporarily took out the entry in autostart.sh just to see what would happen in putty. and like I said, no errors. but when i press the power button (off) it does nothing

julenvitoria

@cyperghost wow! It’s perfect!! I’ll try the other script later

Thanks!

cyperghost

@semper-5 Please do so as you wrote. Take auto entry from autostart.sh!
and do a manuel start via SSH to see error messages. I need the routine how the POLOLU acts with the switch.

Please use sudo /path/to/switch.sh & command with the latest script version.

@julenvitoria You are welcome! Thank you for testing. The other script is also working! I tested several times.

Semper 5

@cyperghost it doesn't output any errors.

I enter: sudo bash /home/pi/RetroPie/scripts/switch.sh &
output: [1] 10921

I think it s working to some extent because if I try to run it again it will tell line 18 & 20 write protection due to device being busy

cyperghost

@semper-5 That's okay ... this [10921] thing is the process number.
So what happens if you press the power button? With the script in background running?

You should see a message like:
Switch press 0 - Switchtype 1
ES-PID: 1232

Semper 5

@cyperghost no message, no activity, no error. nothing :/

cyperghost

@semper-5 What is the output of
cat /sys/class/gpio/gpio24/value

if the power button is pressed, and then if the power button is released?
It should be 1 if pressed and 0 if released

The script must be active for this ;)

Semper 5

@cyperghost it's 0 on both being pressed and released

cyperghost

@semper-5 That's the error here ... but tell me why? That's not possible! The python scripts are working?

Maybe @Yahmez knows the answer?
If we watch for input of GPIO24 (=power button), why there is no change in input value?

Semper 5

@cyperghost I know! Our frustration is real. I mean it works as it should with Yahmez's script. And just to be sure I am following your instructions immaculately, yours is the ONLY script I'm running on this fresh image.

Geez it was embarrassing you guys telling me to use Notepad++ and how to invoke the script LOL. but I do appreciate all your efforts to walk me through it. I'm just thinking you guys must be getting as frustrated with me as I'm getting frustrated with this not working - I'm yelling at this damn box like "you're making an idiot out of me in front of the community, damn you!" haha

Yahmez

@cyperghost
I am late to the game here but if my script works as intended (minus saving metadata which was never implemented) and cypherghost's script is not seeing the button presses then the logical thing would be to compare the two scripts and see how they are being handled differently.

cyperghost

@yahmez ;)
Thank you for stepping in my friend.
So let's compare ;)

#!/usr/bin/python
 
import RPi.GPIO as GPIO
import os, time
 
GPIO.setmode(GPIO.BCM)
GPIO.setup(23, GPIO.IN, pull_up_down=GPIO.PUD_UP)   #Reset switch
GPIO.setup(24, GPIO.IN, pull_up_down=GPIO.PUD_UP)   #Power switch
GPIO.setup(25, GPIO.OUT)                            #ON control
GPIO.output(25, GPIO.HIGH)
 
while True:
  if (GPIO.input(24)):
    time.sleep(0.25)
  else:
    print ("Shutting down...")
    os.system("sudo shutdown -h now")
    break
  if (GPIO.input(23)):
    time.sleep(0.25)
  else:
    print ("Resetting...")
    os.system("sudo reboot now")
    break

and

script version from here
I did not implent reset handling here ;)

mitu

@cyperghost Maybe the wires are connected to other pins ?

cyperghost

@mitu This can only be answered by @Semper-5 but I assume not!
As I remeber he told me, that the python scripts are working ;)

Yahmez

If it just cuts power upon turning off the power switch it means that the on control pin is not going high on boot.
