1、串口自发自收设定串口时钟设定引脚功能中断优先级设定串口 Main文件#include "stm32f10x.h"void RCC_Configuration(void);void GPIO_Configuration(void);void USART_Configuration(void);void NVIC_Configuration(void);int main(void){  RCC_Configuration();  GPIO_Configuration();  NVIC_Configuration();  USART_Configuration(); 

2、  while(1);}void RCC_Configuration(void){      RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);}void GPIO_Configuration(void){  GPIO_InitTypeDef GPIO_InitStructure;  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;  GPIO_Init(GPI

3、OA, &GPIO_InitStructure);    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;  GPIO_Init(GPIOA, &GPIO_InitStructure);}void USART_Configuration(void){  USART_InitTypeDef USART_InitStructure;  

4、USART_InitStructure.USART_BaudRate = 115200;  USART_InitStructure.USART_WordLength = USART_WordLength_8b;  USART_InitStructure.USART_StopBits = USART_StopBits_1;  USART_InitStructure.USART_Parity = USART_Parity_No;  USART_InitStructure.USART_HardwareFlowControl = USART_HardwareFlowCo

5、ntrol_None;  USART_InitStructure.USART_Mode = USART_Mode_Tx 

6、 USART_Mode_Rx;  USART_Init(USART1 , &USART_InitStructure);  USART_Cmd(USART1, ENABLE);  USART_ITConfig(USART1, USART_IT_RXNE, ENABLE); /*接收中断使能*/}void NVIC_Configuration(void) {   NVIC_InitTypeDef NVIC_InitStructure;  NVIC

7、_PriorityGroupConfig(NVIC_PriorityGroup_0);   NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;   /*3.4的库不是使用USART1_IRQChannel，看stm32f10x.h吧*/  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;   NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;   NVIC_Init(&NVIC_InitStructure); }Stm3

8、2f10x_it.c加入void USART1_IRQHandler(void) {     unsigned int i;     if(USART_GetFlagStatus(USART1,USART_IT_RXNE)==SET)     {                       i = USART_ReceiveData(USART1);         USART_SendData(USART1,i);         while(USART_GetFlagStatus(USART1, USART_FLAG_TC) == RESET) ;
