Can I connect the enviro phat to a raspberry pi 4 instead of the rpi zero?
Yes, it should work on any Pi with a 40 pin GPIO Header.
Thx. Is there a way to find the code i wrote in the old sd card that was on the rpi0 and move it over to the rpi4? Im looking thru the sdcard but all i can see are the regular boot files for the rpi0. all i see are the bcm files (broadcom i think, the cmdline and config txts, bootcode and COPYING, the fixups and the kernels and starts plus the overlays folder. I dont see any code files. I did this a while back so Im not even sure where the file would be but I know i used it to log sensor data to a cloud service so i would prefer to just use that code instead of writing it again.
What device are you trying to look at the card on? The boot partition is Fat 32 but the other partition is I think ext3? It’s a Linux Partition which won’t be viewable on a Windows PC.
im on a macbook and ive inserted the sd card into a card reader.
That’s probably not going to work. Do you see both partitions or only just the Boot partition?
i only see the boot partition. How else could i see it?
Plugging into a Linux PC will let you see it. If you have a USB Card Reader, you could just plug it into the Pi 4 via USB.
yeay! thx. I was able to access my files on the desktop. ok so i can copy them over to the rpi using the mv command i guess…
One more thing. Since what im copying is a python file for the envirophat, i also have to install the envirophat library which I tried using this command here:
curl https://get.pimoroni.com/envirophat | bash
from here: Getting started with Enviro pHAT
but i get these errors towards the end:

Any idea how to fix this? Because I tried running:
from envirophat import light
and it fails with:
>>> from envirophat import light
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named envirophat
because the module isnt imported…
so i found this sources edit:
deb http://legacy.raspbian.org/raspbian/ jessie main contrib non-free rpi
but now I get this python 3 error which is sending me back here to the forums :-)

I see jessie referenced in the error messages, are you running Jessie?
I do believe jessie has been archived / removed from main stream etc. What the installer is looking for isn’t there anymore, it’s been moved.
ok so can I upgrade it via the cli or do i need to burn a new image on the sd card?
the reason i ask is I do have some impt files on the rpi…
I. tried this but. get the same errors as before:
as soon as I do these:

and I get a permission denied when doing this cmd:

Here is my. sources:
deb **http://mirrordirector.raspbian.org/raspbian/** **stretch** **main contrib non-free rpi**
I think sudo apt dist-upgrade -y will do it? Might want to research it a bit before you do it?
This is what I get when I run it:

Im trying different mirrors but they. all fail:
If it was me, I’d re flash the SD card. And if you want to avoid the Bookworm Python Virtual Environment hassle, install Pi OS Legacy.
ok, which pi os legacy do you recommend? bullseye 32 bit legacy?
If you want to play it safe go 32 bit. I’ve been using 64 bit with no issues with installers etc.
ive done 32 and 64 bit legacy for rpi3 and i get the rainbow screen for some reason. Any suggestions?
The Rainbow screen is normal, you can disable it if you want.
just add disable_splash=1 to the config.txt.
That being said, it should continue on after you see the rainbow screen to the desktop, does yours?
No it doesn’t, that’s the odd part. It started up fine on Jessie.
I was burning the image with ssh and other settings so I just tried without any settings at all but still it’s been hanging on that rainbow screen for over 5 minutes now.
