Re: Lighthousedeck LED stay off

You can check in the console log (in the python client). You should get some log entries that it locked to LH V1 and after a while that it received calibration data

Re: Lighthousedeck LED stay off

The correct LED sequence when booting (as of 11/8 2020) is
1. blue + red
2. blue + red + yellow
3. blue

The blue LED should stay on

Re: Setting LH Origin Position Automatically

The script that calculates the basestation geometry is based on the opencv function solvePnP (https://docs.opencv.org/2.4/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html). I don't know much about the implementation or the resource requirements for that function, but assuming that i...

Re: Decoding Incoming Data Using Python

I'm not sure the decoding scripts are fully functional, but it should not be too far away. I don't remember what the output is (they were changed around a few times), but you probably have to dig in to them and find a good place to print the actual sweep angles. Lighthouse 2 uses two light planes th...

Re: I want to assign the thrust in the firmware

Hi! Not sure if you want to do this from a PC or in the firmware: If you want to set the thrust from the PC, you should use the pyton lib (https://github.com/bitcraze/crazyflie-lib-python). You can take a look at the https://github.com/bitcraze/crazyflie-lib-python/blob/0.1.11/examples/ramp.py examp...

Re: Cflib

The flow deck uses an optical flow sensor that outputs relative motion in x and y, and absolute distance in z. The Crazyflie will calculate an absolute position based on the relative motion data it gets, but it will accumulate errors over time. The coordinate system will be based on the starting pos...

Re: [cfclient] PySDL version missmatch on macOS

Hi!

It seems as 0.9.6 is hard coded in setup.py. I created an github issue for this https://github.com/bitcraze/crazyflie-c ... issues/425

Until it is fixed you can either downgrade pysdl2 to 0.9.6 or modify setup.py to 0.9.7 (if you are running from source code)

Re: I have some questions of crazyfile2.0 can you help me Thanks

Hi! The Crazyflie has no real notion of its position in space, the on board sensors (accelerometers and gyros) can be used to give a rough idea of its movements but lacks the accuracy for long term position awareness. To be able to hover at a spot without user interaction (autonomous flight) the Cra...

Not sure what the problem is, but if you want to check out how we install gcc in our official docker builder image you can find it here https://github.com/bitcraze/docker-builder/blob/master/src/Dockerfile#L17-L18 If you don't want to install the compiler locally you can use the toolbelt instead, se...
