java - 通过串口监视器和Java同时读取Arduino

Question

我用 java 编写了一段代码来与我的 Arduino 板进行通信。效果很好。我还可以使用串行监视器与 Arduino 板进行通信。

但是当我尝试打开串行监视器时，当java程序正在运行时(监听连接到主板的端口，PORT 32)，它失败了，

串行端口“COM 32”已在使用中。尝试退出任何可能正在使用它的程序。

这是完整的消息(只是为了完整性)

是的，我知道，它是我的 java 程序正在使用该端口。但这是否意味着我不能同时使用这两个程序来访问 PORT32？

希望有人能告诉我解决这个问题的方法。任何帮助是极大的赞赏。谢谢!

您的观察是正确的，串行端口一次只能由一个应用程序打开。有一些软件解决方案可用于拆分串行端口或监视它们，但我对这些解决方案的经验不足，无法给出任何建议。
