windows编程之资源的编译和使用

这里将我写的STC12C5A60S2单片机控制气压海拔测量模块BMP180的程序共享一下，是为了让前辈给予斧正。

更新：2014/04/17 10:22

(也可以用官网封装好的函数BMP180_API  ：http://www.general-files.org/download/gs64624bfeh32i0/bmp180_api.zip.html)

（补充：只需要修改bmp180.h文件中含有 “选择” 字样的部分，就可以达到复用的效果，只需注意中文注释部分）

(提示：因为其中的宏较多，建议source insight查看代码)

对于LCD2004模块，请参考我的另一篇文章《单片机控制2004A液晶屏之模块化编程》http://blog.csdn.net/yagnruinihao/article/details/19999551
