工具效果如下如所示

下面简单介绍一下操作流程

1.打开PyCharm软件

2.创建一个工程

3.给该工程命名

4.在main.py里面黏贴如下的代码

# This is a sample Python script.
# Press Shift+F10 to execute it or replace it with your code.
# Press Double Shift to search everywhere for classes, files, tool windows, actions, and settings.

5.执行脚本

6.如果有提示“No module named 'serial”，需要安装 pyserial，在终端命令行输入：pip install pyserial，如下图所示：

7.在windows下安装一对虚拟串口，可以下载vspd安装，最终结果如下所示：

8.使用第三方工具进行数据互发测试

9.将该工具打包成exe可执行文件

在命令行终端输入：python -m pysimplegui-exemaker.pysimplegui-exemaker

最后点击“Make EXE”，生成如下所示的exe文件
