Using new Inky Phat Yellow.
It’s running on a 4GB Pi4 using Buster
Calendar = OK
Weather = OK
Name badge though, does nothing. No errors, no Inky display change. Nothing. Nada. Zilch.
My thought was perhaps the fonts haven’t installed, but the code isn’t failing on the code import step.
Any ideas, please?
(Also tried again later on Pi Zero W, with the same results.)
Trying again on a daisy fresh OS.
There’re are still lots of error messages - e.g.
python-wikiquotes is required
Installing python-wikiquotes...
E: Unable to locate package python-wikiquotes
Apt failed to install python-wikiquotes!
Falling back on pypi...
Could any of that be the cause of the issue?

This isn’t very well tested prior to sale, is it?

BUT STILL NO BADGE ON THE INKY PHAT!!!
Some packages could not be installed, review the output for details!
pi@raspberrypi:~ $
Which packages?
Is this why BADGE doesn’t work?
Hi Richard,
Sorry to see that, it’ll be changes to Raspbian as it’s upgraded that’ll be causing errors, I’ll give our team a heads up.
It looks like it’s the correct library for the new version, but we’d need to see the full output of the install script to know which packages they were installed. I’d recommend trying both:
sudo pip install inky
and
sudo pip3 install inky
so you can try both python 2.7 and python 3 to see if that makes a difference.
Also please could you confirm you have the SPI interface enabled in raspi-config?
Cheers,
Matt
Hi Matt,
How, why then do CALENDAR and WEATHER work?
SPI is enabled

Of course, no improvement. :(
Any changes to the error messages at all?
Did smbus2 install properly? Does installing it with pip as well as pip3 help anything?
Any output from the name-badge commands?
Which error messages Matt?
SMBUS installed OK, yes. (Calendar and Weather work OK remember!).
pip/pip3 doesn’t seem to have changed anything.
No, nothing from the name-badge commands.
In Thonny, open name-badge.py
Comment-out line 22, # parser.add_argument('--name', '-n', type=str, required=True, help="Your name")
Comment-out line 69, # name = args.name
Add new line 70, name = 'Hello World!'
Execute code.
Success!
Looks like it’s something to do with the name string, but quite what, I don’t know.
We’re suspecting it’s different versions of Pythons used at the command line and in whichever Python utility you’re using (you’ve mentioned Thonny, are you also using IDLE3?)
Might be worth trying:
sudo python3 -m pip install smbus2
That should install smbus2 specifically for the version of python3 that’s run when you use it at the Pi command line.
It’s already happy there with smbus2

Idle3 unavailable, so installed that.

Name badge doesn’t ask for the name, it just crashes.

You’ll want to run it from the “Terminal” so that you can pass your name as a parameter. I don’t think you can pass parameters running the script from Idle3.
Bangs head on wall, sobs quietly into first available cushion…
That’s the first thing I tried Tomm. See first post in this thread.
Apologies, joined the thread a bit late.
Is there any difference if you run the script with python or python3?
No, tried that!

I’m having the same issue on my new pi. Just bought a new pi and an e-ink board. Just put it all together, but can’t get any example to run (except what the manufacturer included in their example bits)
