生成一段通过stm32f103rct6串口助手给串口1发送数据，并且在串口助手上显示串口接收的数据的代码

以下是一段通过stm32f103rct6串口助手给串口1发送数据，并且在串口助手上显示串口接收的数据的代码：

#include "stm32f10x.h"
#include <stdio.h>

void USART1_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    USART_InitTypeDef USART_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1 | RCC_APB2Periph_GPIOA, ENABLE);

    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);

    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_HardwareFlowControl_None;
    USART_InitStructure.USART_Mode = USART_Mode_Rx | USART_Mode_Tx;
    USART_Init(USART1, &USART_InitStructure);

    USART_Cmd(USART1, ENABLE);
}

int main(void)
{
    char data[100];
    USART1_Init();

    while (1)
    {
        if (USART_GetFlagStatus(USART1, USART_FLAG_RXNE) == SET)
        {
            char c = USART_ReceiveData(USART1);
            sprintf(data, "Received: %c\n", c);
            USART_SendData(USART1, c);
            USART_SendData(USART1, '\n');
            while (USART_GetFlagStatus(USART1, USART_FLAG_TXE) == RESET)
                ;
            printf(data);
        }
    }
}

希望对您有帮助！
