Re: Controlling crazyflie through firmware

Hi, Currently, the easiest way to get your code to run in the firmware is to make a deck driver. This is documented on our website and there is a short howto page that you can follow to get your code running in the Crazyflie. For an example of how to use the flow deck from inside the Crazyflie you c...

Re: CRTP Payload Size

Hi, Sorry for the confusion, this has been an historical problem. The payload capability of CRTP packets should be 31 bytes: Crazyradio can handle 32Bytes packets and CRTP is adding 1 byte header. There has been confusion early-on in the firmware development that has set 30 bytes payload limit (31 b...

Re: data from SLAM(ROS)

The ROS driver is setting up a log block for the Crazyflie position there: https://github.com/whoenig/crazyflie_ros/blob/master/crazyflie_driver/src/crazyflie_server.cpp#L517-L523 with a callback that publishes the pose as a ROS TF message: https://github.com/whoenig/crazyflie_ros/blob/master/crazyf...

Re: Communication with Crazyflie

You need to set the address from the client: https://www.bitcraze.io/docs/crazyflie-clients-python/master/userguide_client/#firmware-configuration. Technically it would be possible to set it from a script as well but there is no easy to use API for that, you can look at the client implementation if ...

Re: Cannot scan Crazyflir in client

I think the problem is that the address 0xE7E7E7E7 is 0x00E7E7E7E7 which is different from the default 0xE7E7E7E7E7 address. There should be 5 E7 in the address.

Re: LPS Node firmware update with debug adapter kit

Hi, Yes it is possible. You need to have OpenOCD as well as the required tools to compile firmware installed on your machine and the lps-node-firmware project. You can then compile the firmware with "make" and flash it using an St-Link V2 using "make flash". There is a bit of information about the b...

Re: Communication with Crazyflie

The multiramp example is using one radio to control multiple Crazyflie using low level APIs (ie. sending attitude set-points). If you look in the swarm folder you can find more examples connecting multiple Crazyflie with the same radio: https://github.com/bitcraze/crazyflie-lib-python/tree/master/ex...

Re: BigQuad deck ESC PWM signal not changing

Hi, There can be at least two reason I can think off for the output thrust to stay at 0% (like it is for you, 1ms pulse is 0% thrust): - The Crazyflie sensors are not calibrated. After POST the M1 LED blinks red slowly during sensor calibration, when the sensor are calibrated it starts blinking fast...

Re: EX ANT

EX ANT is a second antenna output from the Crazyflie's radio power amplifier. The intent is to use an external antenna instead of the integrated chip antenna, this could be used to achieve longer range or more directional radiation pattern for example. It is not something that is intended to be usef...

Re: i cannot install usb driver application

Hi,
Can you send a screenshot of the error you are seeing. Zadig should not need to be installed, just launched.

I just tested on a fresh Windows 10 with Zadig 2.4 and the driver installation worked well.
