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：

1. void NVIC_Configuration(void)
   
2. {
   
3.         NVIC_InitTypeDef NVIC_InitStructure;
   
4.         NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
   
5.         
   
6.         NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
   
7.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
   
8.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
   
9.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
   
10.         NVIC_Init(&NVIC_InitStructure);
    
11.         
    
12.         NVIC_InitStructure.NVIC_IRQChannel = USART3_IRQn;
    
13.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
    
14.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    
15.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    
16.         NVIC_Init(&NVIC_InitStructure);
    
17.         
    
18.         NVIC_InitStructure.NVIC_IRQChannel = SPI2_IRQn;
    
19.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    
20.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    
21.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    
22.         NVIC_Init(&NVIC_InitStructure);
    
23.         
    
24.         NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn;
    
25.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
    
26.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
    
27.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    
28.         NVIC_Init(&NVIC_InitStructure);
    
29.         
    
30.         NVIC_InitStructure.NVIC_IRQChannel = TIM3_IRQn;
    
31.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
    
32.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2;
    
33.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    
34.         NVIC_Init(&NVIC_InitStructure);
    
35.         
    
36.         NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQn;
    
37.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 2;
    
38.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;
    
39.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    
40.         NVIC_Init(&NVIC_InitStructure);
    
41.         
    
42.         NVIC_InitStructure.NVIC_IRQChannel = EXTI4_IRQn;
    
43.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
    
44.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
    
45.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    
46.         NVIC_Init(&NVIC_InitStructure);
    
47.         
    
48.         NVIC_InitStructure.NVIC_IRQChannel = EXTI9_5_IRQn;
    
49.         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
    
50.         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    
51.         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    
52.         NVIC_Init(&NVIC_InitStructure);
    
53. }

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
