PIC单片机(Peripheral Interface Controller)是一种用来开发和控制外围设备的集成电路(IC)。一种具有分散作用(多任务)功能的CPU。与人类相比,大脑就是CPU,PIC 共享的部分相当于人的神经系统。

stm32每个IO口都可以作为中断,103系列有19个外部中断线,其中线0-15为外部通用中断。而单片机不止16个IO口。因此每个线表示每组IO的特定的IO口。例如line2对应GPIOA-G.2。外部中断的使用步骤:1)初始化 IO 口为输入。2)开启 IO 口复用时...
学习完定时器中断之后,学习如何通过一个定时器来产生一个PWM波。32的定时器除了TIM6和7,都可以用来产生PWM波。其中1和8是高级定时器,可以同时产生7路pwm输出。TIM1使用pwm波的步骤如下:(1)开启TIM时钟,配置输出IO口为复用推挽输出(2...
