说明

这是一个课程设计内容，需要配合一个温度传感器进行使用，难点是串口的使用。

在本程序中，还需要懂得IEEE 754标准下的浮点数在计算机中的存储方式，否则无法将读取到的二进制数正确的转换为十进制数字。

步骤

Mysql的安装与使用

Codeblocks的安装与使用

codeblocks下使用mysql见我的这篇文章http://blog.csdn.net/celte/article/details/9908877

打开codeblocks后，文件——新建——项目——Win32 GUI Project——FrameBased——下一步——完成，即可编程。

注意

本程序中需要使用ini格式的配置文件，文件如下，还需要使用Mysql数据库，数据库中只需要建立temperature一张表，表中两个字段time（datetime），value（double）

config.ini

[DataBase]
IP=127.0.0.1
DB=sensor
User=root
Pass=1324354657
[Interval]
Time=3000
[GraphOnShow]
OnShow=false
[StartPoint]
Date=2013-09-17
Time=19:37:46

mark.ini

[2013-09-17-19:12:21]
Wrong=37.8
Right=37.9
