一、添加串口模块
cmake中添加:
#添加SerialPort模块 下面整句添加
qt5_use_modules(${PROJECT_NAME} Core SerialPort)
或者
find_package(Qt5Core COMPONENTS Qt5SerialPort REQUIRED)
二、遍历串口
#include <QtSerialPort/QSerialPort>//串口接口
#include <QtSerialPort/QSerialPortInfo>//串口接口信息
/**
* @brief枚举出所有的串口,并寻找出指定描述Description的串口,比如NDI导航头的serialPortDescription可以在设备管理器中查看
* NDI的serialPortDescription一般不会变,可用于自动识别串口
*
*/
std::string NDICAPI::getSerialPortName(std::string serialPortDescription)
{
std::string retPortName {};
foreach (const QSerialPortInfo &info, QSerialPortInfo::availablePorts())
{
//通常通过串口名称进行连接,例COM1,所以在此处获取串口名称
// qDebug() << "Name : " << info.portName();
// qDebug() << "Description : " << info.description();
// qDebug() << "Manufacturer: " << info.manufacturer();
// qDebug() << "Serial Number: " << info.serialNumber();
// qDebug() << "System Location: " << info.systemLocation()<<"\n";
if(serialPortDescription == info.description().toStdString())
{
#ifdef _WIN32 // Windows serial port implementation
retPortName = info.portName().toStdString();
#else // Mac/Linux serial port implementation
retPortName = info.systemLocation().toStdString();
#endif
}
}
if(retPortName == "")
{
qDebug() << "can not find SerialPortName,please check serialPortDescription";
std::cout << "Press Enter to continue...";
std::cin.ignore();
exit(-1);
}
return retPortName;
}

四、Linux串口配置
https://blog.csdn.net/liudsl/article/details/79266003
注意:串口数据/t-/n的转换
config.c_lflag &= ~(ICANON | ECHO | ECHOE | ISIG);
config.c_iflag &= ~(INLCR| ICRNL | IGNCR);
config.c_cc[VMIN] = 0; /* use constant, not interval timout */
config.c_cc[VTIME] =100/100; /* wait time is in 10ths of a second */
注意:清楚缓存区
tcflush(fdComm_, TCIOFLUSH);
tcflush(fdComm_, TCIFLUSH);
tcflush(fdComm_, TCOFLUSH); /* clear input/output buffers */
