STM32+EXTI.rar
- 本例展示了如何使用嵌套中断向量控制器（Nested Vectored Interrupt Controller）来设置IRQ通道。 把3个计时器（TIM2，3，4）设置为在每一个计数器更新事项（counter update event）产生中断。这三个计时器都与各自对应的更新IRQ通道联系起来，并设置他们的中断优先级，TIM2为0，TIM4为2。 在他们各自的中断中：TIM2每1秒翻转一次PC.06的状态；TIM3每2秒翻转一次PC.07的状态；TIM4每3秒翻转一次PC.08的状态
STM32+TIM.rar
- 本例展示了如何设置TIM工作在输出比较-非主动模式（Output Compare Inactive mode），并产生相应的中断。 TIM2时钟设置为36MHz，预分频设置为35999，TIM2计数器时钟可表达为： TIM2 counter clock = TIMxCLK / (Prescaler +1) = 1 KHz 设置TIM2_CCR1寄存器值为1000， CCR1寄存器值1000除以TIM2计数器时钟频率1KHz，为1000毫秒。因此，经过1000毫秒的时延，置PC.06
