Can’t get this to work. Seems there is a conflict between bullseye and bookworm python libraries. python3-spidev can’t be installed.

Hi @David41202. Good to have you on the forums. 🙂

Are you using a package manager like PIP or apt-get to install spidev?  
If so, would you mind pasting the command and error below?

### what’s going on?

Ah that’s super weird. That would suggest to me that the Raspberry PI foundations index’s are unaware of spidev and Python 3.9 in the distro you’re using.  
You totally nailed it when you were talking about Bullseye and Bookworm having a conflict. 🔥

[I found this post online that explains the problem well.](https://dietpi.com/forum/t/installing-spidev/17779/4)

> `python3-spidev` is pulled from `https://archive.raspberrypi.org/` Bullseye repository, while `python3` is pulled from `http://raspbian.raspberrypi.org/` Bookworm repository. This is causing a conflict between versions now. Unfortunately there is still no Bookworm repository available from `https://archive.raspberrypi.org/`

It gets more interesting.  
Just last night at 4:35pm [Bullseye was updated in the Raspberry PI Index.](https://archive.raspberrypi.org/debian/dists/)  
This is wild, but it might be that running `sudo apt update` magics your problem away. Unlikely, but give it a go?

### downgrading to python 3.7

`Depends: python3 (< 3.8)` implies that if the version of python on the system is 3.7 the installer would be chill. You could install it here 🙂 =\> [Python Release Python 3.7.0 | Python.org](https://www.python.org/downloads/release/python-370/)

### using pip

Python’s personal package manager, pip, doesn’t query the Raspberry Pi Archives, instead querying it’s own rainbow tables of packages. It’s frustrating that the apt-get indexing isn’t working as intended, but if you [use Pypi on this occasion](https://pypi.org/project/spidev/) you might find Spidev comes down without a problem.  
`pip install spidev`

You are correct. Using pip install spidev worked.  
Now I have a picture of a cat on the screen, but I need to make it do what I want it to, which is to display some information which is written for an adafruit display hat. It is also st7789 so I hope I can tweak the code to get it working.  
Thanks,  
David

Hi David,

Glad to hear Pix got you all sorted out!  
Keen to see what you make with the screen 😃

We’ll get these amazing notes added to the product page

Well I did get it working as a display for a DigiPi APRS node/decoder, but it was too unstable. Seemed to be a physical problem with the display.

Where can I find more information about this display. Is there a source of instructions to use all its features?

In the end I ordered some Adafruit screens which are known to work without code change.

Thanks for that. The instability was related to the buttons. The application was using the same GPIO pins that the board uses for buttons and RGB LED, for other purposes. It is working again, but it doesn’t use the standard ST7789 python instruction set, so had to change a few words in the python file. Looks pretty on the pizero2W though!

Further to this, the buttons would trigger when my hands came near them, so had to add a command to tie them high rather than floating. All stable now. The graphics commands are different in Bookworm, so have to stick to Bullseye.

Hi @David41202,

Thanks for keeping us updated with the progress for getting this working Stabley.

UPDATE: The Python st7789 and DisplayHATMini libraries have been updated and now work with Trixie. Have to install in a venv but it all is working again. Still one of the nicest displays for the size and price.
