如何使用TIM5的CH4进行捕获？

maninman1981

各位：
      为何没有TIM_TS_TI4FP4的定义？
      如果硬件不行连接到了TIM5——CH4，用于测量一个转速信号，
      即测量脉冲频率，又该如何配置？
      谢谢！

   
  #define TIM_TS_ITR0                        ((uint16_t)0x0000)
#define TIM_TS_ITR1                        ((uint16_t)0x0010)
#define TIM_TS_ITR2                        ((uint16_t)0x0020)
#define TIM_TS_ITR3                        ((uint16_t)0x0030)
#define TIM_TS_TI1F_ED                     ((uint16_t)0x0040)
#define TIM_TS_TI1FP1                      ((uint16_t)0x0050)
#define TIM_TS_TI2FP2                      ((uint16_t)0x0060)
#define TIM_TS_ETRF                        ((uint16_t)0x0070)

 

 

正点原子

肯定可以了，不过我用寄存器的，木有你这个问题。。。
TIMx寄存器组结构体：
