WPF制作简易串口调试助手（上位机部分）

实验环境：vs2013 参考文档：https://docs.microsoft.com/zh-cn/dotnet/api/system.io.ports?view=netframework-4.7.2

下位机部分：https://blog.csdn.net/weixin_42462552/article/details/85937289

一、窗体程序制作：

（一）UI界面

1.首先我们参照网上的串口调试助手将UI界面的大体框架完成

2.其中数据发送区域的文本需要实现自动换行功能，根据网上资料，需要设置TextWrapping的属性为"Wrap"。 3.接下来是对串口号、波特率、校验位等的一些内容设置，其中较复杂的是串口号的设置，需要根据电脑的端口实际情况来确定串口数量，不能同设置波特率属性一般，直接在程序里指定唯一值。
