SPI读取MPU9250 9轴加速度，陀螺仪，磁力计，对于MPU9250而言，除了加速度、陀螺仪外，新增了磁力计模块，但是磁力计模块只支持I2C的读写，
为了能够利用起SPI的优势。作者花了一些功夫，仔细研读了MPU9250 datasheet 整理出SPI读取MPU9250全套工程源码

采用ADIS16405集成IMU组件实现惯性导航，该IMU组件包含了磁传感器，示例程序给出了数据采集代码。集成电路介绍：The ADIS16405 iSensor® product is a complete inertial system
that includes a triaxal gyroscope, a triaxial accelerometer, and a
triaxial magnetometer. The ADIS16405 combines the Analog
Devices, Inc., proprietary iMEMS® technology with signal
conditioning that optimizes dynamic performance. The factory
calibration characterizes each sensor for sensitivity, bias, alignment,
and linear acceleration (gyroscope bias). As a result, each sensor
has its own dynamic compensation for correction formulas that
provide accurate sensor measurements over a temperature range of
−40°C to +85°C. The magnetometers employ a self correction
function to provide accurate bias performance over temperature
as well.
