playout_controls.sh not found

[empydempy]

Hi all,

this project is great. I am pretty new to linux and I guess this won't be too tough to handle.
But I haven't found an answer by searching google...or I didn't get it ;-)

Here is what I get when pressing on volU button which I changed to GPIO 5 because I am using hifiberry miniamp. I think the issue I have is just in the beginning where it says playout_controls.sh not found

python3 /home/pi/RPi-Jukebox-RFID/scripts/gpio-buttons.py
/bin/sh: 1: ./scripts/playout_controls.sh: not found

Thanks in advance for your help.

Hi @empydempy,

do other buttons work, which control the behavior of the phoniebox?
Have you altered the script?
It seems that the script is found at a different place:

File "/home/pi/RPi-Jukebox-RFID/scripts/gpio-buttons.py", line 26, in def_volU
check_call("./scripts/playout_controls.sh -c=volumeup", shell=True)

Hi Miczflor,

thanks for the quick answer.
None of the other buttons work.

Acutally, I installed Rasbian (buster) and ran the Jukebox script on another SD-Card to check if it would work then.
Python and I hope all other tools are installed.

Then I copied the GPIO-buttons script from the samples to the script folder using this command:
"sudo cp /home/pi/RPi-Jukebox-RFID/misc/sampleconfigs/gpio-buttons.py.sample /home/pi/RPi-Jukebox-RFID/scripts/gpio-buttons.py"

After that I chmod +x the GPIO buttons script (sudo chmod +x /home/pi/RPi-Jukebox-RFID/scripts/gpio-buttons.py)

and then ran it without alternating anything. (python3 /home/pi/RPi-Jukebox-RFID/scripts/gpio-buttons.py)

I attached the button to GPIO 26 ("next") -> Unfortunately I get the same result :-(
It does recognize the button and starts the script. But then, at least to me, it can't start/find the playout_controls.sh (which is in the directory: /home/pi/RPi-Jukebox-RFID/scripts)

You are saying that the script seems to be found in another place. Here is a listing of my script folder:
pi@raspberrypi:~/RPi-Jukebox-RFID/scripts $ ls
activate-amplifier.py playlist_recursive_by_folder.php
daemon_mqtt_client.py playout_controls.sh
daemon_rfid_reader.py python-phoniebox
gpio-buttons.py Reader.py
helperscripts Reader.py.experimental
idle-watchdog-countdown.sh Reader.py.kkmoonRFIDreader
idle-watchdog.sh RegisterDevice.py
inc.readArgsFromCommandLine.sh resume_play.sh
inc.settingsFolderSpecific.sh rfid_trigger_play.sh
inc.writeFolderConfig.sh rotary_encoder_base.py
inc.writeGlobalConfig.sh rotary-encoder.py
installscripts shuffle_play.sh
MFRC522.py single_play.sh
pirc522 userscripts

Should I copy the script or the playout_conrtols somewhere else?
Can it have something to do with buster, instead of stretch?
Do I have to "chmod +x" anything else?

thanks once more :-)

Hi all,

it seems that I solved the problem. As soon as I am sure I will post the result.

[empydempy]

Its working for all buttons tested yet. Next, Vol Up/down....so I guess it will work for the other too.

At the moment I commented shutdown out since I am using an oled.

I will close this Issue and hope it helps others running into this problem.
@MiczFlor once again thanks for you help! And yet once more thanks for the great project! ;-)

Here is the modified script which hopefully avoids any trouble with the hifiberry and the oled:

#!/usr/bin/python3
from gpiozero import Button
from signal import pause
from subprocess import check_call

This script will block any I2S DAC e.g. from Hifiberry, Justboom, ES9023, PCM5102A

due to the assignment of GPIO 19 and 21 to a buttons

Added the function on holding volume + - buttons to change the volume in 0.3s interval

2018-10-15

this script has the pull_up=True for all pins. See the following link for additional info:

#259 (comment)

2017-12-12

This script was copied from the following RPi forum post:

https://forum-raspberrypi.de/forum/thread/13144-projekt-jukebox4kids-jukebox-fuer-kinder/?postID=312257#post312257

I have not yet had the time to test is, so I placed it in the misc folder.

If anybody has ideas or tests or experience regarding this solution, please create pull requests or contact me.
