本笔记采用VS2010中的C#语言开发上位机，通过USB接口与助学板进行通信。
项目功能：
1、温度采集：通过DS18B20进行温度采集，采集结果上传到上位机显示
2、温度报警：上位机设置报警温度，下位机设置定时器查询DS18B20采集到的温度与设置的温度比较，室温>=设置温度时启动峰鸣器进行报警。（目前只能实现整数温度的报警，如果想更精确请自行修改程序）
3、LED灯控制：通过上位机发送相应指令给下位机，下位机执行开关灯操作，并返回结果。
4、扩展功能：可以给任意的管脚做 DrvGPIO_ClrBit 和 DrvGPIO_SetBit 操作

更多功能自己去发现吧！

很多功能都是以最简单方式写的，比如定时器只用了9行代码（不包括回调函数）

有不明白的地方可以直接问我，QQ：PHP兼职者

友情提示：如果没有VS2010环境的网友，上位机可以直接运行 UsbApp\bin\Debug\UsbApp.exe 看效果
