使用jSerialComm 函示庫
<dependency> <groupId>com.fazecast</groupId> <artifactId>jSerialComm</artifactId> <version>2.6.2</version> </dependency>
利用 SerialPort.getCommPorts()
找到接micro:bit的com
SerialPort com = SerialPort.getCommPorts()[0];
com.setComPortParameters(115200,8,1,10);
com.setComPortTimeouts(SerialPort.TIMEOUT_SCANNER,0,0);
com.openPort();
InputStream in = com.getInputStream();
byte[] buffer = new byte[com.bytesAvailable()];
String message = "";
for (int i = 0; i < 30; i++) {
int len = in.read(buffer);
if (len > 0) {
message = new String(buffer);
System.out.println(message);
}
Thread.sleep(1000);
len = 0;
}
in.close();
com.closePort();
}
結果
1131431441461491501491491491491501491491491501501501511511511501501511511511521511521511521521511521511511511511521511531521521521521531511521511521501511521531521511521531521531531511531521521521511521511501521521531521521521511521521511511521521531521531531531531 5215215315315215215215215215215115215215315315215215115115215315215215215215215315315415315215315115115215315315215215315315415315315415415315415415415315315415415515315315315415415415415415415415415415415415515315415415415415415415415615415515515415415415515515415 51551551541541541541541551551<DAPLink:Overflow> 1121431441461491501491491491491501491491491501501501511511511501501511511511521511521511521521511521511511511511521511531521521521521531511521511521501511521531521511521531521531531511531521521521511521511501521521531521521521511521521511511521521531521531531531531 5215215315315215215215215215215115215215315315215215115115215315215215215215215315315415315215315115115215315315215215315315415315315415415315415415415315315415415515315315315415415415415415415415415415415415515315415415415415415415415615415515515415415415515515415 51551551541541541541541551551<DAPLink:Overflow> 1131431441461491501491491491491501491491491501501501511511511501501511511511521511521511521521511521511511511511521511531521521521521531511521511521501511521531521511521531521531531511531521521521511521511501521521531521521521511521521511511521521531521531531531531 5215215315315215215215215215215115215215315315215215115115215315215215215215215315315415315215315115115215315315215215315315415315315415415315415415415315315415415515315315315415415415415415415415415415415415515315415415415415415415415615415515515415415415515515415 51551551541541541541541551551<DAPLink:Overflow>
