stm32F103uart中断接收代码

以下是一个基本的STM32F103上使用UART中断接收数据的示例代码：

#include "stm32f10x.h"

#define BUFFER_SIZE 128

volatile uint8_t rx_buffer[BUFFER_SIZE];
volatile uint8_t rx_index = 0;

void USART1_IRQHandler(void)
{
    if (USART_GetITStatus(USART1, USART_IT_RXNE) != RESET)
    {
        rx_buffer[rx_index] = USART_ReceiveData(USART1);
        rx_index = (rx_index + 1) % BUFFER_SIZE;
    }
}

int main(void)
{
    // 初始化UART
    USART_InitTypeDef USART_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE);

    // 配置UART引脚
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 配置UART参数
    USART_InitStructure.USART_BaudRate = 9600;
    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_HardwareFlowControl_None;
    USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
    USART_Init(USART1, &USART_InitStructure);

    // 使能接收中断
    USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);

    // 配置中断优先级
    NVIC_InitStructure.NVIC_IRQChannel = USART1_IRQn;
    NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
    NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
    NVIC_Init(&NVIC_InitStructure);

    // 启动UART
    USART_Cmd(USART1, ENABLE);

    while (1)
    {
        // 在这里处理接收到的数据
    }
}

这是一个简单的示例，它初始化了UART1，并配置为接收中断模式。当接收到数据时，中断处理函数`USART1_IRQHandler`会被调用，将接收到的数据存储在缓冲区`rx_buffer`中。在主循环中，您可以处理接收到的数据。请根据您的需求在示例代码的基础上进行修改。
