Push button to start playing a playlist/stream sample code

[sassen]

Hi, is it possible to have a few dedicated push buttons for the most used playlists/streams on top of having the RFID card functionallity?

I only find instructions for GPIO buttons for play/stop, skip song, volume etc but nothing for playback of playlist/web radio stream.

That could be hacked in. For one specific playlist. You would need to execute a bash script which imcludes the folder name. See top of this script for examples:
https://github.com/MiczFlor/RPi-Jukebox-RFID/blob/master/scripts/rfid_trigger_play.sh
Use double quotes for a folder name with whitespaces
Looking forward to your working prototype. Please post it here.
All the best, micz

Hallo Micz, i´m not good in coding, so i don`t know exactly which solution you prefer but i would try a workaround:

• I track a playlist with a card
• than i would add the following code in gpio-buttons.py
  def def_play1(): check_call("./rfid_trigger_play.sh --cardid=1234567890", shell=True) play1 = Button(4,pull_up_True) play1.when_pressed = def_play1

I try it out when i bulid my next Box. Maybe someone think about my solution and give me a feedback.
Thank you so much for JukeBox4Kids!

Ok. It works. A my idea ist quiet simple and has the advantage that i can easily change the assignment to the button.

Here the again which i add to gpio-buttons.py:

`def def_raab():
check_call("./scripts/rfid_trigger_play.sh --cardid=0005238085", shell=True)
def def_fsam():
check_call("./scripts/rfid_trigger_play.sh --cardid=0005222302", shell=True)
def def_bobo():
check_call("./scripts/rfid_trigger_play.sh --cardid=0005256911", shell=True)

raab = Button(17,pull_up=True)
fsam = Button(27,pull_up=True)
bobo = Button(22,pull_up=True)

raab.when_pressed = def_raab
fsam.when_pressed = def_fsam
bobo.when_pressed = def_bobo`

Perfect - great someone did it. And a good solution for non-coders like me.
Going to try it the next days.
Thanks!

Hi @Bartman83
thanks for the code example. This is roughly what I had in mind with no time to write it :) If you could add this to the wiki, I would be very happy. Otherwise, I'll try to add it some time soon.
All the best, micz

Hi @Bartman83
I added your example to the wiki:

thanks for the contribution!

I've been able to get the jukebox controls working with the GPIO buttons, but I'm having trouble implementing the playlist controls. Here's what I have in my gpio-buttons.py:

I've tripled checked the GPIO connections are correct, and they are. I've even tried changing the buttons. No luck.

Lol. Everytime I post an issue, my problem seems to magically get resolved. I rebooted it a couple times and it works now. 🤷🏽‍♂️
