The Crazyflie PC client enables flashing and controlling the Crazyflie. It implements the user interface and high-level control (for example gamepad handling). The communication with Crazyflie and the implementation of the CRTP protocol to control the Crazflie is handled by the cflib project.
For more info see our wiki.
Running from source
The Crazyflie client requires cflib. If you want to develop with the lib too, follow the cflib readme to install it.
Running from source on Windows is tested using the official python build from python.org. The client works with python version >= 3.5. The procedure is tested with 32bit python. It should work with 64bit python but since it is not tested it can be broken (if so, do not hesitate to send a fix ;-).
To run the client you should install python, make sure to check the "add to path" checkbox during install. You should also have git installed and in your path. Use git to clone the crazyflie client project.
Open a command line window and move to the crazyflie clients folder (the exact command depends of where the project is cloned):
Download the SDL2.dll windows library:
Install the client in development mode:
pip install -e .[dev,qt5]
You can now run the clients with the following commands:
cfclient cfheadless cfloader cfzmq
NOTE: To use Crazyradio you will have to install the drivers
Working on the client with PyCharm
Pycharm is an IDE for python. Any Python IDE or development environment will work for the Crazyflie client. To work on the Crazyflie firmware with Pycharm, install pycharm community edition and open the Crazyflie client folder in it. Pycharm will automatically detect the python installation.
To run the client, open and run the file
You are now able to edit and debug the python code. you can edit the .ui files for the GUI with QtCreator. You can the Qt development kit from the Qt website and open the .ui files in QtCreator.
Creating Windows installer
When you are able to run from source, you can build the windows executable and installer.
First build the executable
python setup.py build
Now you can run the client with
To generate the installer you need nsis installed and in the path. If you
are a user of chocolatey you can install it with
choco install nsis.portable -version 2.50,
otherwise you can just download it and install it manually.
To create the installer:
python win32install\generate_nsis.py makensis win32install\cfclient.nsi
IMPORTANT NOTE: The following will use Homebrew and its own Python distribution. If you have a lot of other 3rd party python stuff already running on your system they might or might not be affected by this.
Install the brew bottles needed
brew install python3 sdl sdl2 sdl_image sdl_mixer sdl_ttf libusb portmidi pyqt5
Install the client
- If you only want to use the client to fly the Crazyflie and don't care about coding
pip3 install cfclient
- If you want to develop the client and play with the source code. From the source folder run
pip3 install -e .
If you want to develop on cflib as well, install cflib from https://github.com/bitcraze/crazyflie-lib-python
You now have all the dependencies needed to run the client. The client can now be started from any location by:
Launching the GUI application
If you want to develop with the lib, install cflib from https://github.com/bitcraze/crazyflie-lib-python
Cfclient requires Python3, pip and pyqt5 to be installed using the system package manager. For example on Ubuntu/Debian:
sudo apt-get install python3 python3-pip python3-pyqt5 python3-pyqt5.qtsvg
Install cfclient to run it from source. From the source folder run (to install
for your user only you can add
--user to the command):
pip3 install -e .
To launch the GUI application in the source folder type:
To launch the GUI after a systemwide installation, execute
The Crazyflie PC client has the following dependencies:
- Installed from system packages
- Python 3.4+
- A pyusb backend: libusb 0.X/1.X
- Installed from PyPI using PIP:
Setting udev permissions
Using Crazyradio on Linux requires that you set udev permissions. See the cflib readme for more information.
