The Crazyflie PC utilities are developed using Python 2.7. The Crazyflie library is used from the command line tools as well as a graphical user interface. For install instructions of PC side software please see this page.

The Crazyflie library can be used to easily integrate control and communication with the Crazyflie quadcopter into an application. Currently the only implementation is done in Python and can be found here.

The Crazyflie control UI is used to pilot the Crazyflie using a graphical user interface. A userguide for the GUI application can be found here. Normally this is started from the start menu (or similar) if you have used an installer. There's also the option of starting it from the command line:

usage: cfclient [-h] [--debug DEBUG]

cfclient - Crazyflie graphical control client

optional arguments:
  -h, --help            show this help message and exit
  --debug DEBUG, -d DEBUG
                        set debug level [minimal, info, debug, debugfile]

The Crazyflie headless client is intended to be run on the Raspberry Pi (see this page for more info), but can also be used from a normal PC.

usage: cfheadless [-h] [-u URI] [-i INPUT] [-d] [-c CONTROLLER]
                  [--controllers]

optional arguments:
  -h, --help            show this help message and exit
  -u URI, --uri URI     URI to use for connection to the Crazyradio dongle,
                        defaults to radio://0/10/250K
  -i INPUT, --input INPUT
                        Input mapping to use for the controller, defaults to
                        PS3_Mode_1
  -d, --debug           Enable debug output
  -c CONTROLLER, --controller CONTROLLER
                        Use controller with specified id, id defaults to 0
  --controllers         Only display available controllers and exit
