这是主文件：

#include "derivative.h"      /* derivative-specific definitions */
void ECT_Init (void)                  //输入捕捉初始化函数
{
   ECT_TSCR1=0x90;                        //主定时器使能，快速清除标志
   ECT_TSCR2=0x07;                        //分频因子为128
   ECT_ICSYS = 0x02;                      //IC缓冲使能
   ECT_TIOS_IOS0=0;                       //通道0为输入捕捉
   ECT_TIOS_IOS1=0;                       //通道1为输入捕捉
   ECT_TCTL4_EDG0A=1;                     //捕捉通道0上升沿

   ECT_TIE_C0I=1;                         //通道0中断使能
   ECT_TIE_C1I=1;                         //通道1中断使能
   ECT_TFLG1=0xFF;                        //清中断标志位
}

#pragma CODE_SEG NON_BANKED

void interrupt VectorNumber_Vectch0 Int_TimerCapture_C0(void) {

   DisableInterrupts;
   ECT_TFLG1_C0F = 1;   //中断标志清除

   EnableInterrupts;
}
void interrupt VectorNumber_Vectch1 Int_TimerCapture_C1(void){

   DisableInterrupts;
   ECT_TFLG1_C1F = 1;   //中断标志清除
   EnableInterrupts;
}
#pragma CODE_SEG DEFAULT

void main(void) {
/* put your own code here */

ECT_Init();
    EnableInterrupts;

for(;;) {
    _FEED_COP(); /* feeds the dog */
} /* loop forever */
/* please make sure that you never leave main */
}
