PID自动调节直流电机的速度。认为规定直流转多少转，通过PID算法自动控制稳定在规定的转速内！-PID automatic adjustment of the speed of DC motor. DC to consider the number of provisions to, through the PID algorithm for automatic control of speed and stability within the required!

关于GPIO学习的例子，非常经典-GPIO study on the example of a very classic

优化级别必需为s,其他优化级别也不会导致编译时出错，但会导致运行时出错。原因涉及局部变量分配堆栈处理方式不同，也就是OS_CPU_A.c那个文件中的移植部分。还有就是其他优化涉及的中断自动保存寄存器的数量有所出入。-Necessary to optimize the level of s, other optimization levels will not lead to compile-time error, but it will result in run-time error. Reasons relating to the allocation of local variables, stack processing in different ways, that is, OS_CPU_A.c that the transplanted parts of the file. There are other optimization related to the interruption of the number of registers saved automatically have access to.
