Crazyflie 2.0, MAC OS X, Python3 Diagnostics Request

Post by silku62 smitha » Sun Sep 13, 2015 5:57 am

I am using MAC OS X yosmite version and python 3.4.3

when I start the python3 bin/cflient, I see the window pop-up and able to see the control panel. But these are error messages on terminal being printed. In addition, I am able to connect over USB - but I cant tell whether I am talking to the crazyflie (one blue, one read is blinking and 1 LED is solid blue).

3 questions:
1) how can I tell I am talking to the copter over USB - the following messages appear on the terminal. (looking for devices never stops).
2) when I connect the radio, I am not sure it is connecting. what is wrong with radio? or how can I diagnose whether it is a setup problem or radio problem? or copter problem.
3) Is there a command to say "Spin motor blade 1, 2, 3, 4" - so I can see the visual effect of running a command and confirm that the USB connection is working or may be radio link is also working.

also, when I physically lift the copter by hand the "Flight Data" area is reflecting that I am moving the copter and changes the pitch/roll/yaw fields also. But at the bottom of the screen it says, "No input-device found, insert one to fly" - See the attached image.

Please advice. Thanks. (See screen shot of control Panel also)

Those messages you see reflect that the python client is looking for a controller. That is, to use the python GUI client, it expects you also have a PS3, PS4, Xbox, or other similar controller plugged in. If you are seeing flight data coming in and the artificial horizon on the GUI is matching your motions, then the Crazyflie is communicating with the GUI client.

As far as "commands" to spin the rotors, please have a look at the files in crazyflie-clients-python/bin. Specifically the ramp.py example. That contains what your are looking for. They do not use the GUI however, they are simply python script examples to operate the Crazyflie.

Hope this helps!
