bn999,
Again, thank you for your reply, as a model aircraft enthusiast, i am deeply attracted by autoquad not only because it is open source but also it's good performance, what's more, there are so many skilled people like you who are so kind to give suggestions. I would like to learn more about it.
Now I have got another problem, i have bought a STM32f3 DISCOVERY board(with sensors LSM303 and L3GD20) and added a MS5611 to it, with the existing parameters, i can't get a good attitude. When i refer to the github, i noticed that benzeng published a version of AutoQuad for PX4/Pixhawk(the sensors used in Pixhawk are similar to mine), however the parameters he offered are still the existing parameters without any change, i think that there should be many differences between the two sets of parameters, could you offer me the set of parameters for Pixhawk if you have? my Gmail is

If you don't have the parameters right now , would you please to show me the name of the algorithm used in calculating the parameters?
