It really looks very beautiful and stylish.
I would like to ask you about OLED display.
I really like this display too and I try to use it in my designs.
As far as I know there are several projects with this display,
256x64 Oled (ssd1322 SPI), 4 Buttons, Rotary - Interface
by Maschine2501.
Unfortunately, this project was shut down by its founder. I was never able to launch it.
Another project, apparently based on the first one, is
[BETA RELEASE] Quadify Plugin – OLED Display, Buttons, IR + CAVA Spectrum Visualiser
by matt.theshepherd
This is a working project on both 3 and 4 volumio, but this is still a beta release and the founder is not very active in supporting it.
Your display looks similar to these projects.
Could you please tell if it is possible, do you used these projects as is, or changed anything in these plugins?
I’m don’t know much about programming, so I can’t fix anything myself.
Regards
