EXTI(Extern Interrupt)外部中断 EXTI可以监测指定GPIO口的电平信号,当其指定的GPIO口产生电平变化时,EXTI将立即向NVIC发出中断申请,经过NVIC裁决后即可中断CPU主程序,使CPU执行EXTI对应的中断程序 支持的触发方式:上升沿/下降沿/双边沿/软件触发 支持的GPIO口:所有GPIO口,但相同的Pin不能同时触发中断 通道数:16个GPIO...
We can use external interrupt pins in various situations ranging from simple notification when a PIR sensor detects the motion of somebody in a room. And up to doing some measurement stuff and calculations like measuring the frequency of a digital sensor such as an “Optical Encoder” to measure...

that is managed by the library. The user has no interrupt interface, and no interrupts are generated on each pulse. Interrupts arrive when the 16 bit counter buffer overflows, so this library has a tiny interrupt footprint while providing support for up to 8 simultaneous quadrature encoders. ...
