EasyD12_PC动态连接库和例子

//---------------------------------------------------------------------------
//软件名称：USB--I2C测试程序(For C++ Builder 5.0)
//开发时间：2002-4-10
//说明：本程序演示了如何在C++ Builder 5.0中静态调用动态链接库EasyD12.dll读写24WC系列E2ROM
//      其中在工程中静态加载动态链接库的步骤如下：
//      1、打开要调用EasyD12.dll 的工程；
//      2、在Project菜单中选择 “Add to Project...”，然后在弹出的对话框中
//         选择 easyd12forcb.lib 文件。点击确定。
//      3、在.cpp文件中声明
//           #include "EasyD12.h"
