EXTI就是External interrupt/event controller, 外部事件和中断控制器, 包含21条边沿检测线. 每条线可以独立设置触发事件(上升沿, 下降沿或两者同时). 一个等待寄存器维护中断请求的状态. 当动作发生(例如按键按下)时, 如果电平状态由低变高, 会在输入线产生一个上升沿信号, 这个信号到达边沿检测电路后, 会被上升...
1 外部中断概述 EXTI(External interrupt/event controller)—外部中断/事件控制器,和在STM32NVIC中断优先级管理(中断向量表)中讲述的CM3内核的外部中断不同。特指的是,在中断向量表中的EXTI的外部中断。STM32的每个IO都可以作为外部中断输入。EXTI管理了控制器的 20个中断/事件线。每个中断/事件线都对应有一个边沿...
