大家从F1或其它系列stm32芯片向F0迁移时,会遇到一个问题,在F0中找不到NVIC_PriorityGroupConfig()函数,其实是因为F0固定了中断优先级配置,没有了抢占式优先级与子优先级的组合配置,统一只有0到3四个优先级选择,在 NVIC_InitStructure.NVIC_IRQChannelPriority中配置...

1.在复位期间及复位刚刚完成后,复用功能尚未激活时,IO 端口会被配置为输入浮空模式。 2.输入数据寄存器 (GPIOx_IDR) 每隔 1 个 AHB1 时钟周期捕获一次 IO 引脚的数据。 复用(Alternate functions) MCU的外设引脚与GPIO口共用,默认作为IO口,但可配置作为多种外设用途。这种配置GPIO口为特定外设功能引脚的操作就叫...
