这不是那么容易，但作为开始你应该使用我们的计步器（MotionPM）或计步器用于腕式设备（MotionPW）库
http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-packages/x-cube-mems1.html
这些库能够根据加速度数据计算步数，然后你可以将步数乘以平均步长并得到不动，类似于速度。

package.These libraries are able to count steps based on accleration data, then you can multiply the step count by average step lenght and get disctance, similarly the speed.
