我用 java 编写了一个代码来与我的 Arduino 板通信。它运作良好。我也可以使用串行监视器与 Arduino 板通信。

但是当我尝试打开串行监视器时，当 java 程序正在运行时（监听连接到你的板的端口，PORT 32），它没有说，

Serial port 'COM 32' already in use. Try quitting any programs that may be using it.

这是完整的消息（只是为了完整起见）

Binary sketch size: 3,994 bytes (of a 258,048 byte maximum)
processing.app.SerialException: Serial port 'COM32' already in use. Try quiting any programs that may be using it.

是的，我知道，它是我的 java 程序，它正在使用该端口。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。有可用于拆分串行端口或监控它们的软件解决方案，但我没有足够的经验来提供任何建议。
