Using Argon One case with fan and powerbutton together with piCorePlayer?

[Aldoszx]

The gpio-shutdown script from the tweaks page will be deleted when I set this to "No"?
I am only asking because the shutdown button is still shutting down so that the USB drives are not cleanly dismounted.

I think you only should uninstall the extension.
The shutdown button must be ON, in order to define the GPIO pin for shutdown.

Paul, it is correct ?

Yes, the fan is loud ! I intend to replace it with another one more silent.
Mine is set to start at 40 degrees, at 10% speed.
Usually the temp stays below 40.

The shutdown button must be ON, in order to define the GPIO pin for shutdown.

If I look into the script, I find the following line:

GPIO.setup(shutdown_pin, GPIO.IN,  pull_up_down=GPIO.PUD_DOWN)

So I think the correct setting should be used.

But I saw the following reaction to the pressed button. Regardless how long I press it, the reaction is always a shutdown.
Although in the code I see that from 2 to 3 seconds (pulses) there should be a reboot happen and from 4 to 5 seconds there should be a shutdown happen. But there is no difference between pressing long or short.

Yes, remove the shutdown overlay and the shutdown monitor extension.

The python script should call “pcp rb” for a reboot. Or “pcp sd” for shutdown.

Drives should be unmounted, but exfat is an odd file system. It doesn’t have direct kernel support.

Thank you !
There is another way to load the i2c-dev module besides user commands?
Could be done automatically via auto start script?

[carsten_h]

Yes, remove the shutdown overlay and the shutdown monitor extension.

What is the correct ist way to do it? Only switching to „No“.?

Correct.

[carsten_h]

Correct.

Ok. That is easy.

The LMS is running now without any problem and the Pi 4 runs at 45°C, which is Ok I think. Even if I build the database new the temperature stays at this value.

The last two times the file systems are clean after switching off via powerbutton.
Regarding the switching off via the powerbutton. Is it possible to see online without a display attached to see if "pcb rb" or "pcp sd" is executed? Maybe via tail -f xxxx.log?

Today I got a Micro HDMI to HDMI cable and could test the output of piCorePlayer. So I can say that always a "pcp sd" is executed, also when I press longer. But that is Ok for me, I only need switching off. I will only start a reboot via the webpage. But now it is clear that the command is executed and that is the great part!

Now I saw the following:

Finished piCorePlayer v6.0.0-b7 startup.

To setup piCorePlayer, use the web interface via a browser:
 - http://192.168.178.109

Press [Enter] to access console.

In the background, ntpd is syncing time between piCorePlayer and the internet.
A large offset between 1970 and now is normal.
/bin/sh: vcgencmd: not found

It seems that the first time the command to get the actual temperature is not working. But I think that this is no real problem.

[Aldoszx]

If I am not mistaken, reboot could be done by double tapping the power button.
It worked for me, at least.

[carsten_h]

If I am not mistaken

Yes, that works! Thank you!

[carsten_h]

The script has to run with root permissions, as it make a call to vcgencmd, which requires it.

I changed the second user script to "sudo python3 /home/tc/argononed.py", but I am still getting the message that vcgencmd is not found.
Should I change the call:

temp = os.popen("vcgencmd measure_temp").readline()

into

temp = os.popen("sudo vcgencmd measure_temp").readline()

?

Have you tried to chmod 775 the argononed.py script?

[carsten_h]

Have you tried to chmod 775 the argononed.py script?

Yes, I did this when creating it.

I tried vcgencmd on the shell and also with sudo and I always get "not found". So there must be something missing. I will search which part includes vcgencmd.

You probably have to install rpi-vc.tcz


PCP web interface/Main/Extensions/Available

install it

If you then try to run it directly you will get an error
VCHI initialization failed

However, if you run it with sudo then you will get something like
temp=46.7'C

and then reboot to make sure everything has been backed up.

IGNORE THIS BIT ... I think it does not apply to pCP
If you can find a way to add the user tc to the group "video" then I think it will not need sudo.
(usermod not in pCP)

Yes, I found it two minutes ago.
This package was under uninstalled packages, but I don't know why? When I first tried the script it has been working, so something has uninstalled it.
The only thing I changed was the gpio-handler for shutdown. Maybe when disabling this, rpi-vc was also disabled?

I had to delete it, reboot, install it, reboot and now it works and it works without sudo.
