NVIC_IRQChannelSubPriority:定义这个中断的子优先级别。 NVIC_IRQChannelCmd:该中断是否使能。 比如我们要使能串口 1 的中断,同时设置抢占优先级为 1,子优先级位 2,初始化的方法是: NVIC_InitTypeDef NVIC_InitStructure; NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;//串口 1 中断 NVIC_InitStructure.NVIC_IRQ...

NVIC_IRQChannel有很多位（19？），每一位标志着一个设备的中断向量的开启。这句话大致就是开启串口的中断向量。我知道的就这些了。
