Type of Raspberry Pi

PiZero W

Linux Kernel version

Linux raspberrypi 5.10.63+ #1459 Wed Oct 6 16:40:27 BST 2021 armv6l GNU/Linux

Expected behaviour

I would expect python3 to not terminate when I run the command

from luma.led_matrix.device import max7219

Actual behaviour

pi@raspberrypi:~/luma.led_matrix/examples $ python3
Python 3.9.2 (default, Mar 12 2021, 04:06:34)
[GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from luma.led_matrix.device import max7219
Illegal instruction
pi@raspberrypi:~/luma.led_matrix/examples $ echo $?

When running from PIL import Image I get the same error

Can you try installing an older version of Pillow, e.g. pip install "Pillow==8.4.0"?

ianglennon commented

I'm going to hold this until #271 gets resolved. If I can't install and run it on a 3B+ then I pretty much have no hope of getting it going on the ZeroW

thijstriemstra commented

Let me ask again; Can you try installing an older version of Pillow, e.g. pip install "Pillow==8.4.0"? And please don't open so many tickets, not needed at all.

ianglennon commented

THIS IS NOT THE SAME ERROR! IT IS NOT EVEN THE SAME RPI!

I'm done.

hey, im trying to help you. no need to get upset!

ianglennon commented

Yeah, I know, sorry for the unnecessary all-caps response. I have quite literally been trying to get this going all day and have had zero luck. I have tried everything that has been suggested on the other tickets, all resulting in some kind of failure. I have simply lost patience with it. This was supposed to be the final and easiest step in designing and building my own device, starting off with a simple 7-digit display with a MAX7219 driver. I had my own PCB fabricated, I spent the morning soldering components to it, and I even got to see it light up. After that, nothing else has gone right.

I'm not bothered about the Pi Zero not working, I only used it because my 3B+ was busy doing something else. Now that it's available I want to focus on that instead. That's the other ticket, btw... #270

I'll re-open that one (I honestly didn't realise I could re-open a ticket) and we'll try again.

ianglennon commented

I foolishly re-opened this one instead of #270. I'm an idiot 🤣

I observed the same error that @ianglennon described so well. I ran pip install "Pillow==8.4.0" as suggested. This fixes the problem. 👍
