Instruction Guide LCD/OLED display using pydPiper

What went wrong is that we're in a weird interregnum period where the Debian folks have changed over to bullseye from buster (thus bullseye is now the "stable" distro and buster is the "oldstable" distro) but the current Raspbian is still based on Buster.

Try this

Code:
sudo apt-get update --allow-releaseinfo-change

then repeat the install_docker.sh script.

Note: I'm uncertain what state your player is in now that the install failed. If you see a message like "Warning: the "docker" command appears to already exist on this system" when you rerun the script then I'd suggest you let it proceed anyway but it's remotely possible it will cause trouble.


I've tested the update step on a fresh moOde player and it allowed the pydPiper/docker installation to proceed without error.

Kent

Works like a charm! Thanks.

Hi,
is there someone running pydpiper on moode 7.4.1?
After the installation of pydpiper the test works fine, but after the final installation of the pydpiper.service the docker installation will not start properly.
It dies after a few seconds or the systemctl status pydpiper returns
● pydpiper.service - pydPiper

I tried a clean installation of moode, then I added "deb https://archive.raspberrypi.org/debian/ bullseye main" to sources.list and did an update and at last, I used "sudo apt-get update --allow-releaseinfo-change" and repeated the install_docker.sh script.

Nothing worked for me.

Any idea?

PS - don't mix up bullseye and buster repos.

Hello,

I know this Topic was already brought up in this thread, but I am not sure about the Conclusion:

Are there any plans to enable pydPiper to show Song data when the Spotify render is playing?

Thank you for update!

Remy,
I have been using pydPiper now for a couple of years and have an intermittent issue that I am not sure is hardware or software related.  After some time the display blanks.  I have assumed up to now that this is a hardware issue, rebooting the system always brings the display back.
Today for the first time only the second line disappeared - so I stopped pydPiper and restarted it - and the display cam back on both lines.  What could cause one line to disappear?
I have speculated that there may be electrical noise getting onto the data but could this only affect one line of the display?

Running 7.6.1
Pi3B+
pydPiper v0.3-alpha
Winstar WEH001602A

Any thoughts?

Maybe contact. I have the same problem with Oled with spectrum software. Changed the cable and no more problems.

That was my assumption. I turned on debug logging so if it happens again I will hopefully be able to see if an error is logged.

Can we use wide IPS display 1920 x 480 resolution with Moode similar Volumio project ? I like to use Moode and like the wide screen also and tried to search and seem no one use Moode with wide screen.
