你不打开比较中断有什么可能会中断？
TIM_ITConfig(TIM1, TIM_IT_CC1,ENABLE);//使能或者失能指定的TIM中断
这个没打开吧？

试过其它pwm模式，都是无法进入中断，无法更改比较值和溢出值，即arr和ccr值，在slave模式下是不是还要做一些其它命令设定或是修改，忘大佬解答

单步运行下看寄存器的值是否正常，计数器到后状态位是否有变化

的确，不能中断，就要看中断是否打开，如果被mark掉，是不会进入中断的。

RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1 , ENABLE);
好像只打开TIM1，TIM3未启动。
