实验室智能管理系统（2）——Arm+QT部分（一）

来源：互联网发布：python 实现http接口编辑：程序博客网时间：2024/06/07 03:38

由于QT本身不自带arm的串口函数，用了别人写的串口函数添加到QT工程中。从网上下载qextserialport-1.2win-alpha.zip
将posix_qextserialport.h、qextserialbase.h两个头文件添加到工程

这里写图片描述

图中的按键变色效果：改变样式表 QPushButton { background-color: rgb(0, 170, 255); border-radius: 3px; color: rgb(255, 255, 255); } QPushButton:hover { background-color: rgb(245, 69, 234); }
