Re: Cannot find a Crazyradio Dongle

Just for your information: Yesterday I looked again at this situation and I figured out what the problem was. On my old system "import usb.core" failed. Therefore pyusb1 was set to False. On my new system pyusb1 was set to True since there is a usb.core module. My files are indeed not up to date. It...

Re: Cannot find a Crazyradio Dongle

Well, it's not up to date. But I don't think that this is the problem. I use the same code on my old laptop and there it's working. I don't know if that is a clue but if I try to flash the firmware with the radio NOT plugged in, then my two laptops don't show exactly the same information in the buil...

Re: Cannot find a Crazyradio Dongle

yes and yes.

For the libcflie I need the udev rules too and it's working. The Crazyradio is available by using "lsusb"

[SOLVED] Cannot find a Crazyradio Dongle

Hi! I got a new laptop so I copied all my crazyflie projects from my old system (Ubuntu 14.10) to my new system (Ubuntu 15.10). I managed that everything is working but the crazyradio to update the firmware on the crazyflie. I'm using the libcflie library. This library works and I'm able to access t...

Re: Delay in logged data?

I want to track the crazyflie with 2 cameras. With the resulting 3d-coordinates I want to realise: - LQ-regulator for the 12 dimensional quad-dynamics (position, velocity, euler, gyro) - regulator based on model predictive control (12 dim) For the mpc approach I need an optimal control problem solve...

Re: Delay in logged data?

Update: Calculating the motorratios on the crazyflie with 6ms old sensor data results in a little bit better result than calculating the motorratios on my pc with logged (actual) sensor data. But still: in fact you can't fly with it. You can only use it to take off... Even with 2ms old data the craz...

Re: Delay in logged data?

Update: Now I'm sending the motorratios and an ID to the copter. Additionally I log this ID on the crazyflie. Then I meassure the duration from "sending an ID" to "this ID is back on my pc by logging it". The average duration is about 6ms. So my logged sensor data are in average at most 6ms old. To ...

Re: How to customize response CRTPpackets?

Hi, thanks for the reply. I've already used the logging system but for some reasons my regulator doesn't work. At the moment I think, that the logged data are not "up to date". See also my other thread: https://forum.bitcraze.io/viewtopic.php?f=6&t=1708 I'll try the suggestion with the callbacks. Th...

How to customize response CRTPpackets?

Hi, I want to calculate the motorratios on the client. Therefor I have to get the gyro data and euler-angles. Ideally I send the motorratios to the crazyflie and the response (I think there is one?) contains the data I'm interested in. But I'm not sure where I have to make the adjustments. So can yo...
