Re: Error while "make all"

Hi,

I do not recognize this error.

Code: Select all

make clean
make mrproper
git pull
git checkout master
git submodule update --init
make

Re: Control of two Crazyflies

Unfortunately cfzmq was not designed to control more than one Crazyflie and it has never been updated to do so. If keeping matlab is a hard requirement for you I can see 4 solutions to go forward: - Running a second cfzmq client on different ports using a different Crazyradio. To use a second Crazyr...

Re: which controller used for velocity setpoint?

When using the PID controller, the velocity setpoints are handled in position_controller_pid.c to calculate acceleration setpoints: https://github.com/bitcraze/crazyflie-firmware/blob/57b0ea1/src/modules/src/position_controller_pid.c#L196. The acceleration setpoints are then handled in controller_pi...

Re: GITHUB downloading problem

This error is odd, this dependency is supposed to be optional. The best is to clean up your tree and try to compile again:

Code: Select all

make clean
make mrproper

Hi, The lighthouse setup is not happening in the client. You should follow the instructions from the wiki: https://wiki.bitcraze.io/doc:lighthouse:setup At the end of the setup phase, you should have lighthouse geometry data that you can copy-paste in the Crazyflie firmware code and flash the modifi...

Re: Multiranger deck

No you cannot use this board with 5V system, you should not connect it to a 5V I2C bus (ie. an I2C bus with 5V pull-up), if you do so you risk damaging the sensors (and the Crazyflie is you are connect to it). As I mentioned, you can power VCOM with 5V, but you should use a 3.3V I2C bus connected to...
