[How to do instruction] LCD/OLED display using pydPiper

[TheOldPresbyope]

may be pydpiper have some sort of incompatibility with bullseye?

mean time i am running moode v8 with oled @ adrii (install guide), lirc for remote with out any issues

I see one error in your configuration. The time zone should be Asia/Calcutta, not ASIA/Calcutta. That's what is causing the traceback and ultimately the message

Code:

ValueError: First argument to to_local() should be a universal time.

As for the rest of your configuration, I don't see a problem, but I'm neither a user of these displays nor an expert on Docker and containerization.

If I read through dhrone's python code, I see that this initial message

Code:

root@moode:/app# python pydPiper.py
GPIO not installed

gets generated in display-related routines when the python RPi.GPIO module hasn't been loaded. There are various places in the same routines requesting this module be loaded. Running pip in the container to list all available modules, I see RPi.GPIO among them, so I don't know why it isn't loaded in your case.

If occurred to me that I might not be triggering these display-related routines in my test so I went back and reconfigured. I selected the same display as you did, yada, yada, yada, and restarted. I get exceptions because there is no display physically present to drive the i2C lines but I still don't get the "not installed" message you do.

Aside: Python2 officially sunset three years ago this month. The debian bullseye distro on which moOde is built has only python3.9 installed (and the RPi.GPIO module is present) whereas the docker container which we are loading has python2.7 installed. AFAIK, this doesn't matter since pydPiper (which is written in python2 dialect) is running within the container, but I thought I'd mention it. Like I said, I'm not an expert in containerization. I thought naively it would insulate one from differences in debian distros (at least within the same architecture family such as arm vs x86).

Perhaps one of the other users who have posted to this thread in the past would care to comment about pydPiper and moOde 8.
