首先，对不起我的英语，这不是我的母语。
我正在尝试与RxTx库建立Java接口以与串行端口通信。我使用Jigloo创建了我的界面（对我很羞耻），因为我的Java知识非常有限。
我现在要做的是通过在Java界面中推送JButton将数据从Java发送到我的电子板。但这是问题，我真的不知道该怎么做。我读到我必须使用InputStream和OutputStream，但我应该把它放在哪里？我应该创建另一个类还是类？
以下是我的Java UI的代码：

答案 0 :(得分：0)
我想您可以查看以下链接中的RXTX示例，以了解此库的工作原理：
http://rxtx.qbang.org/wiki/index.php/Two_way_communcation_with_the_serial_port
别担心，不是那么困难。你需要：
一个处理串口连接的类：TwoWaySerialComm，
另一个写入串口的人：SerialWriter，
最后（这不是严格必要但强烈建议）另一个类在GUI和串口编写器之间建立桥梁（换句话说，Controller模型中的MVC）。
因此，每当您按下JButton时，您都应该调用一些Controller方法，而这个方法应该弄明白该怎么办。
