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-EXTI-and-Key
- STM32 用外部中断做的键盘，使用外部中断线0 13和15，而且键盘具有优先级，功能较全面-STM32 to do with the external keyboard interrupt, external interrupt lines 013 and 15, and the keyboard has a priority, features a more comprehensive

- This example shows how to configure an external interrupt line-THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS * WITH CODING INFORMATION REGARDING THEIR PRODUCTS IN ORDER FOR THEM TO SAVE TIME. * AS A RESULT, STMICROEL

- ARM中断方式LED灯显示程序源代码，调用函数库，很好的例程-The ARM interrupt LED lights to show programming source code, call the library, a good routine
IR_RS232
- 红外遥控代码,需要重新配置SysTick的中断优先级为最高，要不然SysTick延时中断抢占不了IO EXTI中断,或者当你用其他定时器做延时的时候，要配置定时器的优先级高于IO EXTI中断的优先级.(Reconfiguration of SysTick interrupts the highest priority, otherwise SysTick delay interrupts cannot preempt IO EXTI interrupts * because the defa
