RT-Thread Complementary Filter (STM32 + 6-axis IMU)

Author: wuhanstudio Original link: https://zhuanlan.zhihu.com/p/611568999 Recently, I have been looking at the Prediction section of unmanned driving. EKF (Extended Kalman Filter) can be used to fuse data from different sensors, such as IMU, Lidar and GNSS, to give more accurate state predictions. I happened to have a 6-axis IMU on the development board at hand. […]

Complementary functions and strings ~ Go

Supplement the use of closures, recursion, anonymous functions, callback functions, strings packages, and strconv packages. Closure The go language supports functional programming: It supports using a function as a parameter of another function, and also supports using a function as a return value of another function. closure (closure): In an outer function, there is an […]
