本历程实现了一个完整的层次状态机HSM，可根据UML方便的写出相应的状态机代码。特别适合复杂状态机的开发。(This process implements a complete hierarchical state machine (HSM), according to the UML state diagram convenient to write the corresponding state machine code. Especially for complex state machine development.)

完成mpu6050的姿态角解算，包括卡尔曼，一阶以及二阶滤波算法(caculate the angels of the mpu6050)

哈工大嵌入式实验，基于ARM写一个简单计算器的实验，(HIT the embedded experiment, based on the ARM write a simple calculator experimental)

stm32中准确延时用的文件,因为时钟速度过快且应用广，要实现ms的延迟是很困难的，所以用嘀嗒时钟。(make sure the delay time is just the time we wanted.)
