没人用过tim1输入捕获吗，附上代码：
void TIM1_Init（void）
{
TIM1_PSCRH=0X00;
TIM1_PSCRL=0X00;
TIM1_ARRH=0XFF;
TIM1_ARRL=0XFF;
TIM1_CNTRH=0X00;
TIM1_CNTRL=0X00;
TIM1_CCER1&=0XEE;
TIM1_CCMR2=0X02;
TIM1_CCER1=0X15;
TIM1_IER=0X02;
TIM1_CR1=0X85;
}
#pragma vector=0x0E
__interrupt void TIM1_CAP_COM_IRQHandler(void)
{
if(TIM1_SR1&0X04==0x04) //代表上升沿到来？
{
TIM1_SR1=0X00;
}
CH1输出互补的pwm，我用CH2来捕获其上升沿
