Re: [SOLVED] Firmware not support Magnetometer on 9-axis MPU

Until recently the only Git command I have run was clone. So you have probably quadrupled my Git skills now :)

Info is much appreciated.
thanks

Re: Firmware does not support Magnetometer on 9-axis MPU9250

Thanks Tobias,

It makes sense now. I cloned what I thought was the CF2 firmware but my Git skills are lacking and did not add -b crazyflie2 to the clone command :D


eg

Code: Select all

git clone -b crazyflie2 https://github.com/bitcraze/crazyflie-firmware.git
Thanks

Re: Part No for Power Switch. Crayflie2

Thanks Chad - I think I have more chance of hiring fairies to switch it on and off for me than getting my fat fingers to do it :)

I think I will try the top actuated switch next.
Thanks

CF2.0 Debug Adapter How to question.

Hi I would like to set my self up to be able to debug the firmware. I've done a bit of research, but I don't have clear picture on how it all fits together and what i can actually do with it in addition to being an easy way to perform a low level flash. To set myself up, would I be correct in assumi...

[SOLVED] Part No for Power Switch. Crazyflie2

hi,
The power switch on my CF2.0 is faulty. What is the correct part No or equivalent? Are there possibly 'top' actuated button replacements I could use, because side actuated does not work well with my 'fat fingers' :)
tks

[SOLVED] Firmware not support Magnetometer on 9-axis MPU9250

The latest Crazyflie firmware appears to use Honeywell HMC5883L driver hmc5883l.c to get the Magnetometer x,y,z data. The MPU9250 contains an AK8963 chip not a HMC5893L chip. I thought perhaps the register addressing and control are the same but they are not. For example hmc5883l uses address 05h &a...

Re: Crazyflie 2.0 feedback

The power button is driving me crazy , it's too small, I really struggle to switch it on. Trying to get the CF2 into dfu mode with the USB is almost impossible for me. It's really annoying :( EDIT. Confirmed the On/Off button is now broken , probably because I pushed too hard. I am now using a wire ...

Re: Calculating Compass Bearing - using Honeywell Formula.

I cannot make any sense of the mag data being returned. I have applied the Honeywell formula to the data , yet i see no rotation or changes in the mag data if I rotate the CF2 in 360 degree turns. Do I potentially have hardware issue? I have been scoping through the firmware of the magnetometer code...

Calculating Compass Bearing - using Honeywell Formula.

Playing with mag parameters and I was researching how to calculate the Compass Bearing based on the mag.(x,y,z) values and I noticed that the firmware seems to be re-using the MPU-6050 code and could not see anything specific for MPU-9250. The MPU-9250 spec sheet refers the magnetometer specs as AK8...

Re: CF2: Where can I find a list of Variable and parameter n

Hi Marcus, Thanks the video was very informative. I had only looked at the Python API not the CF2 firmware. An easy way to publish the list might be to look at using Doxygen to document the source and then add a document publish step at build time. I believe doxygen supports C/C++/Python and runs on...
