Re: More compact Linux client's presentation for copter

Hi
I fear that there is a bug somewhere, because I had a "segmentation fault" in the client. I am looking for, but it's not easy...

Re: Client freeze

New: something like the discontinuities of the roll rate appears when cf2 is on the back after a crash. But it differs from my graph because it stops as soon as cf2 is put back on its feet...

Re: Client freeze

I don't like to reproduce this behaviour because it appears after hard crashes... I will investigate stabilizer.c

Altitude formula in crazyflie-firmware

Hi, I am not satisfied with the values of altitude above sea level that I can see on the Crazyflie python client. Sensor seems to be really unprecise and a look at the firmware shows a very costly formula, using pow function. Furthermore, I am not sure that the formula is correct and I replace "...

Client freeze

Hi, I mentionned somewhere, and I read other posts considering the freezing of the crazyflie python client after a crash. I discover a reason of this freezing: the controller output shows hard oscillations of roll rate: P_20171216_164934_r.jpg Thus the commands of the joypad are absolutely inactive....

Re: More compact Linux client's presentation for copter

Yes, it should be! I added a parameter "analog" in the config.json file, set to "true" if you are sure that the joypad is correctly configured. I lost a copter due to a PS3 joystick whose thrust command was only 0 or full stroke! Best is to put in main config.json, in src/cfclien...
