3.RCC相关函数
3.1.函数RCC_APB2PeriphClockCmd
3.2.函数RCC_APB1PeriphClockCmd
3.3.函数RCC_AHBPeriphClockCmd
3.4.函数RCC_ADCCLKConfig
4.SysTick函数——SysTick_Config
3.0版以后的STM32固件库在标准外设库中移除了SysTick的驱动，因此用户必须调用CMSIS定义的函数。
注意：
SysTick_Config()是有返回值的，当设置的计数值（即括号内的值，如“SystemCoreClock / 1000”）不符合要求时（例如设置值超过24位时，就会返回1）就返回1，否则返回0.所以：
if (SysTick_Config(SystemCoreClock / 1000))
{
/* Capture error */
while (1);
}
上面这种写法是种容错手段。若是SysTick_Config()设置正确，那就可以继续执行下面的语句，否则的话就陷入死循环，不再继续执行。
5.NVIC相关函数
5.1.函数NVIC_Init
全部中断名称如下：
注意：先占优先级又叫抢占优先级，只有该优先级比较高才能打断当前中断服务程序。从优先级又叫响应优先级，该优先级比较高只是针对同时发出中断请求时，优先相应从优先级高的中断。
示例：
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_4); //设置中断优先级组
NVIC_InitStructure.NVIC_IRQChannel=EXTI4_IRQn; //外部中断4初始化
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority=0;
NVIC_InitStructure.NVIC_IRQChannelSubPriority=0;
NVIC_InitStructure.NVIC_IRQChannelCmd=ENABLE;
NVIC_Init(&NVIC_InitStructure);
NVIC_InitStructure.NVIC_IRQChannel=EXTI15_10_IRQn; //中断10初始化
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority=1;
NVIC_InitStructure.NVIC_IRQChannelSubPriority=6;
NVIC_Init(&NVIC_InitStructure);
5.2.函数NVIC_PriorityGroupConfig
5.3.函数NVIC_SetPriority
此函数用于设置中断优先级。调用格式如下：
NVIC_SetPriority(SysTick_IRQn, n);
其中，第一个参数为中断类型。第二个参数为优先级（0-15，0最高，15最低）。
NVIC_SetPriority(SysTick_IRQn,7); //设置SysTick_IRQn抢占优先级为7
6.EXTI相关函数
6.1.函数GPIO_EXTILineConfig
注：设置外部中断时，需要开启端口的AFIO复用时钟。
6.2.函数EXIT_Init
6.3.函数EXTI_GetITStatus
用在刚进入中断服务程序确定中断是否发生。为SET表示该中断确实发生，为RESET表示中断没有发生。
6.4.函数EXTI_ClearITPendingBit
注意：该函数在退出中断服务程序前必须使用，用于清除中断标志位。

注意：说明一点，就是除了串口1的时钟使能在APB2ENR寄存器，其他串口的时钟使能位都在APB1ENR。
7.1.函数USART_Init
USART初始化函数USART_Init指向结构体USART_InitTypeDef，其成员定义如下：USART_BaudRate：设置波特率，如9600,115200等。
USART_WordLength：设置数据长度。
具体值：USART_WordLength_8b或USART_WordLength_9b
