Java串口通信,如何获取并使用源码?
Java串口通信可以使用RXTX库。以下是一个简单的示例:,,“java,import gnu.io.CommPort;,import gnu.io.CommPortIdentifier;,import gnu.io.SerialPort;,,import java.io.IOException;,import java.io.InputStream;,import java.io.OutputStream;,,public class SerialExample {, public static void main(String[] args) {, try {, CommPortIdentifier portId = CommPortIdentifier.getPortIdentifier(“COM1”);, CommPort commPort = portId.open(“SerialExample”, 2000);, SerialPort serialPort = (SerialPort) commPort;, serialPort.setSerialPortParams(9600, SerialPort.DATABITS_8, SerialPort.STOPBITS_1, SerialPort.PARITY_NONE);,, InputStream in = serialPort.getInputStream();, OutputStream out = serialPort.getOutputStream();,, out.write(“Hello, Serial!”.getBytes());,, byte[] buffer = new byte[1024];, int len = in.read(buffer);, System.out.println(new String(buffer, 0, len));,, in.close();, out.close();, commPort.close();, } catch (Exception e) {, e.printStackTrace();, }, },},“,,这段代码使用RXTX库实现了一个简单的Java串口通信示例,通过串口发送”Hello, Serial!”字符串,并接收串口返回的数据。
