How to understand the principles of Crazyflie working
Posted: Tue Oct 22, 2019 3:07 pm
Hi guys, I am new to the drone area. I would like to understand the principles of Crazyflie flying like the controller and some state estimation's source code. I found all the building source code are in there https://github.com/bitcraze/crazyflie-firmware
. But it's to0 much for me. I would like to focus on the control and state estimation's part. Does anyone can send me the sepcific part of this? Thanks a lot!

The core of the Crazyflie control happens in the stabilizer loop: https://github.com/bitcraze/crazyflie-f ... zer.c#L245
and generally speaking the control algorithms (sensor, estimator, controller, ...) are in the module source folder: https://github.com/bitcraze/crazyflie-f ... odules/src
Unfortunatly there is no up-to-date high-level docuementation of the code architecture. The next best things is then to read the source code and to already have a basic understanding of how a quadrotor is controlled. For you a good starting point is the stabilizer loop.
