Hi guys,
This is exactly what I’ve been looking for - great job!
Where can I get this OLED module and is there an instruction how to add it to the RPI4?
Is there already a suitable case for the OLED available?
Cheers
Robert

Many thanks guys!
i was looking for a OLED plugin that is working with OTA, especially for my DACBERRY boards (easy OLED integration)
Will the plugin selectable in plugins management in future?
@Josh2000 thanks. I will check your work and come back later 
Thanks again.

Hi Robert
I’m glad you like it 
I got my OLED from eBay and paid about £4. You can get them on AliExpress too. The type of I2C display to get and instructions are all on the GitHub page <https://github.com/supercrab/volumio-p plugins/tree/master/plugins/miscellanea/mpd_oled>
If you google mpd_oled you should see lots of projects other people have made and get some ideas from them. There is nothing official at the moment.

Hi @judydudi
You’re welcome!
The plugin isn’t official yet and isn’t part of Volumio. I don’t know if the team plan to make it official yet, maybe you could ask them? I’m still waiting on one last thing before I make a pull request for my changes so the team won’t know anything about the plugin until I do that first…
Cheers
Mase
Well done ! I think it will help a lot of users.
But for me, the biggest thing concern mpd.conf
This solution will not work with service that not use mpd (Spotify, Spotify connect etc).
In a near future, Volumio based on buster will be out. It will provide a new alsa pipeline that allows to easily use a specific asound.conf. so I think the good way is to use this mechanism to make a universal plugin. This is not documented yet though… .
We already have plugin working that way. let us know 
And once again z good job!

I tried on volumio buster, it does not work
the issue is related to this command in your build script
PLAYER=VOLUMIO make
on buster-based systems, it should be changed to
PLAYER=MPD LDLIBS="-li2c" make

I think he is already aware, the correct command comes from his readme

Thanks @balbuze
The solution does work with non mpd players but it’s a bit of a faff. Lots of users want to see the visualiser work with Spotify, etc. There are currently 2 options to get around this: change alsa config in asound.conf to route the audio using loopback (hard to get right) or use mic in as the audio source but not all soundcards have mic in.
Mpd_oled uses a program called CAVA which takes mpd's FIFO output. I don’t know enough about Volumio, MPD, Buster, CAVA or linux to suggest how it would work, but I’m sure that are more intelligent people who can help!

@Darmur ah right, I’ve updated my instal.sh to fix this so should be sorted now.

I hope so @Darmur - I haven’t tested it fully but it should work. It’s a great issue to find because everything else has been tested and this is something I never thought of testing!
Hi,
I just checked my german translation and found it is looking kind of ugly on smaller displays because of too long text.
I will rework it and upload a better version soon -

Hi Mase,
I’ve found it on Alibaba and will order it:
Thanks
Robert
That’s the one! There’s also a 2.4 inchhversion too - if you like bigger screens but they cost about $20.
Hope it come soon!
Cheers
