你注意到底是触发中断还是捕捉中断；
另外 你到底是哪个STM32型号，注意启动文件的一致性；

ssyx1234 发表于 2016-9-22 08:15:58

触发中断，我用TIM2可以，TIM1就不行，不知道哪里出问题了。。。

先用TIM1调调定时中断能进去不，先保证配置什么没有问题。

ssyx1234 发表于 2016-9-22 10:49:09

进不去啊！

hjl2832 发表于 2016-9-22 13:45:55

:L,你上面的代码不是把TIMER1配置成了PWM模式了吗？

hjl2832 发表于 2016-9-22 13:46:58

既不是定时模式，也不是计数模式，更不是输入捕获。

看看函数名与.S的对的起不
