标签：Tkinter text self send tk 串口 font recv 调试
2020年元旦，武汉出现了不明原因肺炎，搞得人心惶惶，只好宅在家里。闲着也是闲着，于是把很久之前用python写的一个串口调试助手再修改一下。
简单说明一下：
- 以前是准备在debian系统里调试单片机用的，基于python 2.6，GUI是用自带Tkinter做的，不用安装第三方库。
- 修改了之后，可以跨linux、windows平台（我没有MacOS系统，只能放弃），python 2.6/2.7/3.7都简单测试了一下，暂时只能说都可以用。
- 只实现了基本功能，没有自动发送、发送文件、保存等功能，这些以后有时间再增加。
- 需要第三方pyserial库，请“pip install pyserial”自行安装。
先上一个截图
下面是代码，供大家参考（我比较懒，没添加注释）。
