利用C++实现嵌入式系统的实时通信功能

#include <iostream>
#include <serial/serial.h> // 串口库

int main()
{
    // 创建串口对象
    serial::Serial serial_port("/dev/ttyS0", 115200, serial::Timeout::simpleTimeout(1000));
    
    // 打开串口

        std::cout << "Serial port opened successfully!" << std::endl;
    }
    
    // 发送数据
    std::string send_data = "Hello, serial communication!";

    // 接收数据
    std::string receive_data = serial_port.read(20);
    std::cout << "Received data: " << receive_data << std::endl;
    
    // 关闭串口
    serial_port.close();
    
    return 0;

#include <iostream>
#include <sys/socket.h> // socket库

int main()
