飞凌FCU1104嵌入式控制单元JAVA读取串口
作者:互联网
系统为Ubuntu
尝试用RXTX-JAVA读取,发现ARM32系统需要编译驱动。
于是尝试用google的JSSC类库,能读取数据
//读不出扩展版 串口 String[] ttys = SerialPortList.getPortNames(); System.out.println(Arrays.toString(ttys)); //指定串口设备读取 String[] baseTTy = new String[]{"/dev/ttymxc1","/dev/ttymxc2","/dev/ttymxc3","/dev/ttymxc4","/dev/ttyXRUSB0","/dev/ttyXRUSB1","/dev/ttyXRUSB2","/dev/ttyXRUSB3"}; for (String tty : baseTTy) { //开启线程 new Thread(new Runnable() { @Override public void run() { //设置串口 SerialPort serialPort = new SerialPort(tty); try { System.out.println("open " + tty); //Open port serialPort.openPort(); //We expose the settings. You can also use this line - serialPort.setParams(9600, 8, 1, 0); serialPort.setParams(9600,8,1,0); while (true){ try { byte[] readData = serialPort.readBytes(); System.out.println(tty + " Rec: " + HexUtil.encodeHexStr(readData).toUpperCase()); // 往串口写入数据 // serialPort.writeBytes(); }catch (Exception e){ try { Thread.sleep(20); } catch (InterruptedException ex) { ex.printStackTrace(); } continue; } } } catch (SerialPortException e) { e.printStackTrace(); try { serialPort.closePort(); } catch (SerialPortException ex) { ex.printStackTrace(); } } } } ).start();
maven配置
