Re: Individual control of the motors on the crazyflie

In principle what you are doing should make the Crazyflie roll 20 degree. Though, I think I might be missing an important information because from what I understand there is no way you manage to get your Crazyflie to " stands still in the air" with open loop control like this code seems to to. A cou...

Re: Accessing raw thrust channel values in firmware (PS4 controller)

The buttons values are not sent to the Crazyflie. I do not think these button in particular sends messages to the Crazyflie (the Crazyflie has a "stop" message that could be used for kill-switch but I think the current client implementation will "just" stop sending packets when this button is presse...

Re: Deviation issue

Usually you can find out what is happening by connecting a debugger yes. You have to be careful to not reset the CPU when starting debugging though: usually I am doing that by starting gdb from the console manually since IDEs will often start by resetting the CPU. For local variables, they should be...

Re: Deviation issue

Are you running in debug mode and what LED are solid RED, both or just one? If it is both RED LED and you are running debug mode, it looks like a hard-fault or an assert. This can happen for many reason. The best would be to attach a debugger to it to see why the Crazyflie has stopped. If you are no...

Re: Do I need a crazyFlie if I have the bolt?

The Crazyflie bolt implements brushless motor driver output independently of the expansion deck port, this means that the deck port is completly free to attach any deck while the bigquad deck uses quite a lot IO on the deck port. Bolt is also a single-board solution versus the CF2+bigquad two board ...

Re: Hovering scripts

It seems that you are having a state estimation or control issue then. Your modification and the python scripts only operates on setpoints which will only work if the state estimation and control is working correctly. I just spin-up ROS in a VM to test and as I expected, take-off sleep land is worki...

Re: Lighting Condition for Optical Flow Breakout Board

Hi, I have not observed this exact problem before. The flow sensor has an auto exposure mechanism, so this is what might be happening there. There is two things I can think about: - The flow deck does not require high level of illumination. So one things to try would be to reduce the strength of the...

Re: a question about Crazyflie2.0 take off

Hi, After the discussion you have had by mail with Kimberly, it seems that your flow deck is not detected by the Crazyflie since its identification memory is not programmed. The quickest way to solve this problem would be to program the memory yourself, since you seem to have a python development en...

Re: Downloading firmware

No, the compiler do not come with eclipse unless you have installed a special embedded distribution of eclipse. One way to find out for sure is to type the command "which arm-none-eabi-gcc". If it returns something in "/usr/bin/..." you have installed the compiler with apt-get and you need to remove...
