Re: python client keyboard control

I was a bit quick and misunderstood the question, now I understand what you want to do :-) One issue is that you have to call the command command at least 2 times per second which I'm not sure you will be able to do using your code. I think that the event loop will lock until you press a key. Or? If...

Re: python client keyboard control

Hi! The script you are trying to use requires the Flow deck for velocity control. Are you using the Flow deck? If you just want to control the Crazyflie from a terminal using a joystick I would recommend using the headless client that is in the crazyflie-clients-python repository : $ bin/cfheadless ...

Re: 50 % more on my bill with shipping and taxes

Hi Jean-Claude, I am sorry that this caused problems for you. When you buy from the Bitcraze store the goods are sent from Hong Kong. This means that when it arrives in France it is subject to VAT plus potential import duties (as stated when ordering). Unfortunately the shipping for the Crazyflie 2....

Re: Crazyflie 2 battery charger

Nice build! We've never actually put the side-by-side before so thanks for the feedback on the width. I've added an issue for the hardware so if we make a new revision we will try to slim down the board.

Re: Crazyflie 2 battery charger

Hi,

I've just created a page on the wiki with the layout, schematic and a few pictures of the charger we built for our lab. Each charger will charge at most 500mA so if you can supply 5A you should be good. Don't forget to check the max rating of the connectors.

Let us know how it turn out!

Re: Hover implementation

Hi,

You can add multiple logging configurations and you can start and stop them. It's not possible to do "one-shot" logging, but you can set up a logging configuration and when you get the first value back stop it.

Re: LPS node failed to set dtr/rts

Since the DFU is working and the log from production shows output from the UART I think it's a firmware issue. It might be something wrong in the EEPROM, do you have the toolchain set up? If so then do one build where you call this function to write a default configuration to the EEPROM?

Re: Need Help to control crazyflie 2.0 polling pitch,yaw,roll

Yes, you can either call stop() on the log configuration or delete() on it. The difference is that if you call stop on the log configuration it is still present in the Crazyflie 2.0 but the data stop coming. If you call delete it is removed (and the data stopps coming). There's a limited amount of l...

Re: LPS node failed to set dtr/rts

One more thing. When Linux tries to check if the device is a modem it will send commands to it. Unfortunately some of these contain 1 and 0, which will reset the anchor address (I think the final state is 0). To make things easier you could disable this so you keep the correct anchor address and can...
