#if defined(EXAMPLE_SPEEDMONITOR)    //这些宏定义是在哪定义的
  void speedmonitor_start(void);
#endif
#if defined(EXAMPLE_POTENTIOMETER)
void potentiometer_start(void);  
#endif   
#if defined(EXAMPLE_RAMP)
  void ramp_start(void);
#endif   
#if defined(EXAMPLE_PI)
  void NewPIval_start(void);
#endif   
#if defined(EXAMPLE_CONTROLMODE)
void TqSpeedMode_start(void);
#endif
上边是STM32电机库一个工程的部分程序，使用了很多的#if defined()
以#if defined(EXAMPLE_SPEEDMONITOR)    //这些宏定义是在哪定义的
  void speedmonitor_start(void);
#endif
为例  EXAMPLE_SPEEDMONITOR是在呢定义的，
或者是说怎么 使  void speedmonitor_start(void);这一句有效，难道需要自己添加对应的宏定义？


那么 下边类似的使用方法，这些宏 也需要自己定义？？？

typedef struct CMCI_t *CMCI;
从上边这个语句中 应该有一个结构体struct CMCI_t 但是这个结构体在哪？它的定义没找到？？
