串口叫做串行接口，也称串行通信接口，按电气标准及协议来分包括RS-232-C、RS-422、RS485、USB等。 RS-232-C、RS-422与RS-485标准只对接口的电气特性做出规定，不涉及接插件、电缆或协议。USB是近几年发展起来的新型接口标准，主要应用于高速数据传输领域。
工作中，经常要用到串口来做数据的读写，今天我们来自己做一个串口工具，这一节，我们先把基础的框架先搭建好。
一.环境配置
1.这边我就直接使用的 Qt Designer 来设计串口界面的布局。
（1）先来制作我们串口的端口选择，以及波特率，串口的开关等：
这边用到了groupBox、label、comboBox、pushButton几个控件。
（2）接下来制作我们的串口高级设置部分：
（3）然后就是串口数据发送部分：
这边做了两种，ASCII、HEX类型。
（4）包括数据发送、接收文本框：
（6）工具栏制作：
包括了，文件、设置、帮助、退出四个功能。
（7）最终布局如下：
2.生成对应的 .py 文件
