Q：在程序make阶段，出现了串口库库文件缺失导致的函数定义未被实现的报错：

A：安装相关串口库，以下是相关文件

libserial-dev_1.0.0-4_arm64.deb

libserial1_1.0.0-4_arm64.deb

gcc-10-base_10-20200411-0ubuntu1_arm64.deb

libgcc-s1_10-20200411-0ubuntu1_arm64.deb

libc6_2.27-3ubuntu1_arm64.deb

libgccjit-7-dev_7.5.0-6ubuntu2_arm64.deb

gcc-7-base_7.5.0-6ubuntu2_arm64.deb

libgcc-7-dev_7.5.0-6ubuntu2_arm64.deb

libasan4_7.5.0-6ubuntu2_arm64.deb

libubsan0_7.5.0-6ubuntu2_arm64.deb

以上文件存在依赖关系，顺序已经忘了，请自行尝试。

并修改CMakeList.txt文件，加入：

set(SERIAL_LIBRARY “/usr/lib/${CMAKE_LIBRARY_ARCHITECTURE}/libserial.so”)
set(SERIAL_INCLUDE_DIR “/usr/include/serial”)

include_directories(${SERIAL_INCLUDE_DIR})

Q：CH340插上后无法识别出/dev/ttyUSB0

A：请使用/dev/ttyPS1，通过串口直接发送数据

例如：

driver = std::make_shared<Driver>("/dev/ttyPS1", BaudRate::BAUD_115200);
if (driver == nullptr) {
    std::cout << "Create Uart-Driver Error!" << std::endl;
    return -1;
}
// 串口初始化，打开串口设备及配置串口数据格式
int ret = driver->open();
if (ret != 0) {
    std::cout << "Uart Open failed!" << std::endl;
    return -1;
}
string str = "1234";
for(auto& c:str){
    driver->senddata(c);
}

unsigned char ch;
driver->recvdata(ch,(size_t)10000);
for(int i=0;i<10;i++){
    driver->senddata(ch);
}
