有没有大神指导一下基于库3.5的nvic怎么配置？

我之前一直用老版本的固件库使用手册，来学习固件库3.5的使用。之前一些外设感觉还好，虽然有些小不同但还是稍微改改就行了。现在学中断，发现变化好多，之前那么多功能函数只剩下5个了，而且我也不知道他们有什么用，请问这个该怎么搞？？

例程比较多呀    随便一个看看就知道了吧好像

我是这么弄得，参考正点原子和野火的例程：

void NVIC_Configuration(void)
{
      NVIC_InitTypeDef NVIC_InitStructure;
      NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
      
      NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
      
      NVIC_InitStructure.NVIC_IRQChannel = USART3_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
      
      NVIC_InitStructure.NVIC_IRQChannel = SPI2_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
      
      NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
      
      NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
      
      NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
      
      NVIC_InitStructure.NVIC_IRQChannel = EXTI4_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
      
      NVIC_InitStructure.NVIC_IRQChannel = EXTI9_5_IRQn;
      NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
      NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
      NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
      NVIC_Init(&NVIC_InitStructure);
}
只用到了你贴图里的函数中的前两个。
后三个函数，暂时还未用到过。

用CUBE吧，大部分的函数知道是干嘛的就行了
