STM32F103C8T6与移远EC600N串口通信代码

以下是STM32F103C8T6与移远EC600N串口通信的基本代码：

#include "stm32f10x.h"
#include "stdio.h"

#define USART1_DR_Base 0x40013804

int fputc(int ch, FILE *f)
{
    USART_SendData(USART1, (uint8_t) ch);
    while (!(USART1->SR & USART_SR_TXE));
    return ch;
}

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_Speed = GPIO_Speed_50MHz;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    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 recvByte;
    USART1_Init();

    while (1) {
        if (USART_GetFlagStatus(USART1, USART_FLAG_RXNE) == SET) {
            recvByte = USART_ReceiveData(USART1);
            printf("Recv Data: %c\n", recvByte);
        }
    }
}

其中，使用的是USART1串口通信，串口波特率为115200。在主函数中，通过`USART_GetFlagStatus()`判断是否有数据接收，并通过`printf()`函数输出接收到的数据。你可以根据需要修改代码以满足你的具体应用需求。
