Developer Environment and Client on a Raspberry Pi 3 with Jessie

Posted: Fri Apr 01, 2016 3:23 pm

I have set up the Crazyflie Development System and PC-Client on a Raspberry Pi 3 using the new Jessie operating system, following the Crazyflie VM as a guide.
I can access it both using VNC from my PC and on an attached "Pi Official Touchscreen Display" with a pannable larger virtual desktop.

This is how I set up the Crazyflie components,
I hope someone finds it useful!

Cool!
If you feel inclined, I think this would be a perfect write up for https://www.hackster.io/bitcraze/projects. Especially the client part. That makes an awesome portable client setup!

I found an error in: The script section

Add the Update All Projects script and desktop link

which advises you to use the script from bitcraze. This has a file structure with the user home 'bitcraze', whereas my installation has the user home 'pi'.
I have corrected the script in my original post to reflect the user home 'pi' being used.

Hi! First I should say that I am using Ubuntu Mate 16.04 on the rpi3. Your instructions went without a hitch, with everything installing smoothly. After the final reboot, I attempted to run the cfclient from the terminal, after which it promptly announced that it did not detect a pyqt5 installation. This contradicts apt-get, which shows python3-pyqt5 as being installed. Any ideas about how I can resolve this error? Thanks in advance, I want to make sure I can get this up and running before I purchase the happy hacker bundle

####UPDATE####

I tinkered around a little bit without much headway, and then used

sudo apt-get purge python3-pyqt5 -y && sudo apt-get autoremove -y && sudo apt-get update -y && sudo apt-get install python3-pyqt5 -y

and voila, the client is up and running, and i can even run it remotely through ssh with X11 forwarding.

Now to scrape together some cash for the bundle.

Did you install the client with "pip3"? what you are describing could be because you are running the client with python2 instead of python3.

That was a strange thing about it, while trying to get it to work after the final reboot I tried installing with pip3, but it would throw errors,

sudo -H pip3 install PyQt5
and
sudo -H pip3 install python-qt5

both failed, reinstalling with apt-get got the user interface up and running. Now I just need to get the drone and test it out.

Other than that, we now know that the installation instructions work for both Raspbian and Ubuntu Mate

Thanks for the update. Good to know that the instruction works on Raspberry pi too.

The fact that installing pyqt5 with pip does not work is not surprising since this is a binary package and it is only compiled for x86_64 (https://pypi.python.org/pypi/PyQt5/5.8.2).

It is interesting that the modified solution works with Ubuntu Mate. But then Raspbian and Ubuntu are from the same stable.

In coming to the original solution I had to resolve problems with python versions and java versions (for Eclipse).
With python it was a matter of checking as two versions are in use at the same time.
With java the following commands were very useful in identifying the versions present and permitting one to be identified as the default.

Check Java versions:

Code: Select all

apt-cache search oracle-java

Found 1.7 and 1.8

Select chosen java version from those installed

Code: Select all

sudo update-alternatives --config java

Chose v 1.8 WORKS

I hope this helps if those problems should arise.

Thanks for the update.

How is eclipse working in the raspberry pi? I would expect it to run out of memory very quickly.
