**首先**搜索jSSC 并下载jssc包

[http://www.mvnjar.com/org.scream3r/jssc/2.8.0/detail.html][http_www.mvnjar.com_org.scream3r_jssc_2.8.0_detail.html]

或者

https://download.csdn.net/download/xiatiancc/10519259

**然后**把该包加入到Eclipse 项目中（通过*file->build path->configure build path->java build path->Libraries->add external jars)*

*![70][]*

*![70 1][]*

引用jssc.jar文件。

import jssc.SerialPort;  
import jssc.SerialPortException;  
   
public class SerialRecieveData\{  
   
    public static void main(String\[\] args) throws InterruptedException\{  
    new Thread(new Runnable()\{                                                            //开启线程  
@Override

// TODO Auto-generated method stub  
SerialPort serialPort = new SerialPort("/dev/ttyACM2");     //设置串口  
       try \{  
           //Open port  
           serialPort.openPort();  
                              //We expose the settings. You can also use this line - serialPort.setParams(9600, 8, 1, 0);  
           serialPort.setParams(SerialPort.BAUDRATE\_9600,   
                                SerialPort.DATABITS\_8,  
                                SerialPort.STOPBITS\_1,  
                                SerialPort.PARITY\_NONE);  
           String buffer = serialPort.readString(5);                  //从串口读取5字符字符串  
           System.out.println(buffer);  
           if(buffer.trim().equals("Hello"))\{  
            System.out.println("start write");  
            serialPort.writeBytes("1".getBytes());                 // 往串口写入数据  
           \}else\{  
            System.out.println("failed");  
           \}  
           //Closing the port  
           serialPort.closePort();  
       \}  
       catch (SerialPortException ex) \{  
           System.out.println(ex);  
       \}  
\}\}  
    ).start();  
    \}  
  
\}
