前段时间在WIN10系统+VS2017环境下安装了USB开发的驱动环境(详见我的博客【如何在win10+VS2017环境下安装USB驱动开发套件WDK】),今天介绍一下如何建立一个简单的HID设备枚举工程。文中的工程使用VS2017社区版建立和编译,文中对整个工程的建立、配置、编码过程进行了详细的介绍,大家可以参照自己执行。如果觉得麻烦,也可以点击此处【CSDN下载压缩包】直接下载我编辑好的整个工程,或者直接去我的码云克隆,地址是【https://gitee.com/leon1741/MyFirstHIDTest】。不过建议大家去码云里克隆,因为这里的代码我会随时保持更新,而CSDN上的压缩包则是最早的版本。
新建一个空白项目即可。工程名称我输入的是MyFirstHIDTest,大家可以自定义修改。
工程建好之后,新建一个cpp源码文件:
源码文件名我输入的也是MyFirstHIDTest.cpp,大家可以自定义修改。
工程建好之后,要对工程进行一些设置:
1、设置工程的字符集为多字节字符集,以免后面编译代码时出现问题。
2、添加必要的依赖库(hid.lib;setupapi.lib):
输入以下代码:
#include

#include

/*********************************************************************************************************************/
// 模块宏定义
