Re: micro-SD deck log only zeros for PID controller commands

Another important evidence to this case is that when I log the data over the radio (using the python client) all these signals are logged well. Attached is an example over the radio at 50Hz that illustrates what I am saying. The limitations now are, as you may know, that it is impossible to log all ...

Re: micro-SD deck log only zeros for PID controller commands

The strange thing is that the sensors signals are being gathered at 500Hz just fine, but the signals sent to the controller most are lost... I am attaching a .csv that contains all the results for you to take a look. Consider the signals and the config.txt as in the first post in this thread. Notice...

Re: micro-SD deck log only zeros for PID controller commands

I took the Flow Deck but I still have problems trying to log the PID controller signals at 500Hz :( . I figured out by trial and error that it is not possible to have buffers bigger than 100 or so. The problem is that I fly for about 2 or 3 minutes, trying to log at 500Hz, but when I decode the file...

Re: micro-SD deck log only zeros for PID controller commands

I have just tested the same configuration using this time only 50Hz and it worked. So it seems to me that I can not log these control signals using 500Hz. Why is that? Is it because of the resources competing problem (could work without Flow deck) or is there another kind of conceptual problem in tr...

micro-SD deck log only zeros for PID controller commands

Hello guys, I have been trying to log some custom variables in the PID controller: controller.cmd_thrust controller.cmd_roll controller.cmd_pitch controller.cmd_yaw controller. r_roll controller.r_pitch controller.r_yaw, controller.accelz You can see what they mean in the branch https://github.com/a...

Re: Fly Crazyflie 2.1 inside a 200mm pipe

Hi, Kimberly. What would be the correct way to add a new possibility of a controller to be chosen by the user in the firmware? I believe there is an implementation of a different possible controller already (Mellinger) so maybe there is already an interface to add new controllers. If you can point m...

Re: Fly Crazyflie 2.1 inside a 200mm pipe

Hi, Kimberly. Thank you for your help! :) I have talked to Dr. Ewoud Smeur and he is willing to collaborate in the implementation of an INDI controller for the Crazyfle. I will try to do something under his guidance, and he might have some of his own student on it as well. What would be the best app...

Re: Fly Crazyflie 2.1 inside a 200mm pipe

Hi, Kimberly. Thank your very much for your answer. Yes, I had considered the problems you mentioned before thinking about looking into the low level controller. Sorry for not making that clear. Take a look at the following presentations with charts and video so you can take a look at the experiment...

Fly Crazyflie 2.1 inside a 200mm pipe

Hi, guys! Call me crazy, but I want to fly the Crazyflie 2.1 inside 300mm pipes! I have built a mockup pipeline to start experimenting with. First attempt was with what I have out of the box, including the Flow deck and the Multiranger deck, controlling with the joystick (through cfclient) and I fai...
