Not working with latest Raspberry Pi OS 64bit

[bobster316]

I have never had any issues with ledshim working with raspberry pi os 32 bit.

I just upgraded my raspberry pi 4 to the latest raspberry pi os 64bit.

When i try to run the install script i get the following error, can you please help to advise/

pi@raspberrypi:~ $ sudo curl https://get.pimoroni.com/ledshim | bash % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 38790 100 38790 0 0 180k 0 --:--:-- --:--:-- --:--:-- 180k

This script will install everything needed to use LED SHIM

Always be careful when running scripts and commands copied from the internet. Ensure they are from a trusted source.

If you want to see what this script does before running it, you should run: 'curl https://get.pimoroni.com/ledshim'

This hardware is not supported, sorry! Config files have been left untouched

I think 64bit Raspbian is identifying as "debian" and breaking our creaky old installer scripts, what do you see when you run lsb_release -a?

These install scripts can be largely ignored if you just python3 -m pip install ledshim and grab the examples from here.

Hi Philip

Please see below based on your email

@.:~ $ lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 11 (bullseye) Release: 11 Codename: bullseye @.:~ $

@.:~ $ python3 -m pip install ledshim Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple Collecting ledshim Downloading https://www.piwheels.org/simple/ledshim/ledshim-0.0.2-py3-none-any.whl (8.3 kB) Installing collected packages: ledshim Successfully installed ledshim-0.0.2 @.:~ $

What do i do next?

I have updated the installer so it should now forge ahead instead of throwing the unsupported message.

[4lxAnd3r]

so did you get it working? i just cannot get it running in any way :/ would appreciate every bit of help thx

[Gadgetoid]

@4lxAnd3r are you encountering any specific errors?

[EpicallyJess]

I’m trying to use it on a Pi5 with the 64-bit Bookworm release and I can’t get it working. It doesn’t even download the examples. (Reminder to myself to post the output of the install text when I’m back at home on my computer). Can anyone help?

[Gadgetoid]

Hopefully this will be fixed by https://github.com/pimoroni/led-shim/pull/15

I can't for the life of me find an LED Shim to test with- I think mine's soldered to a Pi Zero somewhere.

[EpicallyJess]

I have 2 unsoldered. I live in Ontario Canada; wish i could send to you to test. I'm an uneducated pleb when it comes to coding and even the structure for following updates on a forum like this. Is there anything I can do to help? Would happily follow instructions to test for you.

Thank you, and no worries- I'm sure one will turn up in the office. I think it's been out of production a while and I am not the most organised!

You should be able to hopefully - and easily... famous last words - install the software like so-

git clone https://github.com/pimoroni/led-shim -b repackage
cd led-shim
./install.sh --unstable

This should work on Bookworm since it sets up a virtual environment for you. Or it should, anyway!

Once installed you may need to activate the virtual environment (sigh) for the Python examples to work-

source ~/.virtualenvs/pimoroni/bin/activate

Let me know if you have trouble at any point- these are supposed to be easy(ish) to install, so you'll probably catch problems I've overlooked.

[Gadgetoid]

Oh wait hold up, I have totally flubbed the repackaging and it wont work!

[EpicallyJess]

Two separate code snippets...

@.***:~/led-shim $ source ~/.virtualenvs/pimoroni/bin/activate

-bash: /home/epicallyjess/.virtualenvs/pimoroni/bin/activate: No such file or directory

@.***:~/led-shim/examples $ python cpu_temp.py

Traceback (most recent call last):

File "/home/epicallyjess/led-shim/examples/cpu_temp.py", line 6, in

import ledshim

ModuleNotFoundError: No module named 'ledshim'

So, another noob question... how do I roll back the installation?

[Gadgetoid]

It should be working now.

Basically the installation when it works properly is entirely self contained within the ~/.virtualenvs/pimoroni virtual environment. This is just a folder that, by means of some whacky PATH manipulation, just appears to Python as the Python/modules location for your system.

You activate an environment with source ~/.virtualenvs/<the directory it lives in>/bin/activate and deactivate it by typing deactivate.

I've opted to use the pimoroni environment across all of our installers, but you can:

1. Uninstall everything by just removing that virtual env folder
2. Uninstall a specific module by activating it, and using pip uninstall X

Since the installer is currently too broken to really do anything with system Python, you probably won't have anything to roll back yet.

Note: I've written more than anyone would care to know about virtual environments here - https://github.com/pimoroni/boilerplate-python/pull/13

I also started, but didn't get anywhere much with, this: https://pimoroni.github.io/venv-python/

It's easier (if we take liberties with the word easy), generally, just to:

sudo apt install virtualenvwrapper python3-virtualenvwrapper

And then add /usr/share/virtualenvwrapper/virtualenvwrapper.sh to your ~/.bashrc.

This makes the command for switching to a particular virtual environment just:

workon <virtual env name>

And is what I use generally for not going mad while developing.

[EpicallyJess]

I'm thinking this is way over my head. I'm not sure how to do what you're saying,.

[EpicallyJess]

Still having difficulty with this. I think I'm gonna give up.

There should not be any need to roll it back. Just running the latest installer should, in theory, give you an environment with the library installed and ready to go.

You do need to make sure you've activated that new environment, though, which you can normally do - for our software - by typing the following into a command-line:

source ~/.virtualenvs/pimoroni/bin/activate

This will activate the environment once for your current user session in the terminal into which you typed it. This means you'll need to run scripts from this command line in order for them to work.

(Currently Thonny will also not see any library installed via pip using this method, for bonus frustration.)

Yes this is convoluted and frustrating and tedious and difficult to explain and a brick wall to beginners who just expect to be able to install things and have them work. I'm stuck just trying to figure out better ways to work around it.

[EpicallyJess]

I never did get anywhere with this. I'm wondering if I should just go to the 32-bit OS so there's no issues. Oh well.
