Planeptunia's questions

我有一个运行基于 Debian 的 Linux 发行版的微控制器。
我有一个 Nextion 屏幕，通过 /dev/ttyMOD1 端口上的 UART 连接到它。我有一个脚本，它使用 stty，并使用 cat 从屏幕获取数据并将其输出到 mqtt 主题。当我从 shell 运行脚本，或者在系统启动后重启服务时，我能够通过 ssh 连接，它运行正常。但是，当系统启动时，服务内部的 cat 任务由于某种原因无法运行，只有在服务重启后才能运行。
脚本和服务文件对用户具有 +x 权限。我需要帮助来解决 cat 在启动时无法运行的问题。

脚本和服务的文本：

我正在开发一个用于修改游戏的工具，我想将自定义类型重新制作为 C# 类。此类型有 1 个必需属性和许多其他可选属性。我从 XML 文件中获取自定义类的所有数据，那么有什么方法可以改进这个构造函数吗？

    public class Item(
         string identifier,
         string? nameIdentifier = null,

            }

            return newItem;
        }
    }
}

我想到过两种可能实现的方法，即将属性作为字典或包含所有可用属性的新自定义类型传递，但我不确定它们是否会更好。
