89C51单片机精确定时详解-89C51 Elaborates on precision timing

9轴姿态传感器MPU9250的姿态解算程序，利用了9250的磁场传感器信息，比六轴更精确-9-axis attitude sensor MPU9250 gesture solver using a magnetic field sensor information 9250, more percise than 6-axis

MPU9520 DMP解算 说出来角度精确-MPU9520 DMP calculating

MPU6050-DMP，用于解算姿态角，四轴控制，如欧拉角等等。DMP有校准模块，读取数据更精确，排除干扰。另，市面有硬件DMP，可参考选用。(Used to solve the attitude angle, four axis control, such as Euler angle, and so on. DMP has a calibration module that reads data more precisely and eliminates interference. In a
