Re: Source code for Bookshelf application ?

AFAICT it's not (yet) available on the RPF/RPT github repos.
You can download the source with 'apt source' (after un-commenting the appropriate line in sources.list).
Or download the current version directly: http://archive.raspberrypi.org/debian/p ... 0.4.tar.xz

Re: Problem with Function? Maybe

First of all you need to post code in a code block, like below. The problem with your code is that the cleanup on the last line is inside the while loop. You're resetting the GPiO settings and then trying to use the GPIO again. Removing the indentation of the cleanup one should resolve the problem i...

If you're using Virtualbox you're using an x86 version of the OS.

Re: sudo python3 No module named 'cv2'

You probably installed the cv module locally (just for user pi).
If you used pip / pip3 you have to install it globally with 'sudo' e.g.

Code: Select all

sudo pip3 install opencv
using the correct module name of course.

If you have a fully updated / upgraded Raspbian Buster then it's the same OS. It's only a name change.

I think this is a misleading message. It is way to technical of a message for an end user and doesn't even explain why. A simple message that says "This platform does not have a PCI bus" would be way better.
