python开发串⼝通信界⾯_对Python简单串⼝收发GUI界⾯的
实例详解
忙活了三个多⼩时，连学带做，总算是搞出来了⼀个具有基本功能的串⼝通信PC机的GUI界⾯，Tkinter在python中确实很好⽤，⽽且代码量确实也很少，不⾜的是Tkinter不⾃带combox，但是幸运的是我下载的2.7版本⾃带了包含有combox的ttk模块，于是乎问题就顺利解决了。
下⾯是源代码，⼀些错误提⽰功能还没有做，⽬前只是简单地实现了下位机与PC的通信界⾯，下位机还是⽤的STM32F103

root.title("Serial GUI")python怎么读取串口数据
#ry("3000x4000")
app = GUI(root)
root.mainloop()
