一、实现功能
将Ubeeto物联网开发板通过USB线连接电脑后，每隔5秒开发板会模拟如下的一系列按键动作：
- win+r，唤出“运行”对话框
- n o t e p a d ，输入”notepad”并回车，唤出记事本文本
- h e l l o w o r l d . . ，在记事本输入”hello word..”文本。
二、完整代码
注意： 如果你的项目中同时用到Ble蓝牙功能时，一定要先初始化Ble蓝牙之后，再调用LIB_UsbConfig函数初始化USB功能。
--先配置USB口以USB键盘模式工作
LIB_UsbConfig("KBD")
--开始大循环
while(GC(1) == true)
do
LIB_DelayMs(5000)
--模拟键盘组合按键WIN+R调出运行界面效果
combine_tab = {"GUI","R"}
LIB_UsbKbdSend("COMBINE", combine_tab)LIB_DelayMs(200)
--模拟键盘输入notepad和回车键效果，来创建记事本文本文件
single_tab = {"N","O","T","E","P","A","D","ENTER"}
LIB_UsbKbdSend("SINGLE", single_tab)
LIB_DelayMs(500)
--模拟键盘在记事本文件上打出hello world..效果
single_tab = {"H","E","L","L","O","SPACEBAR","W","O","R","L","D","DOT","DOT"}
LIB_UsbKbdSend("SINGLE", single_tab)
end
如果感兴趣，上面代码中出现的LIB开头的库函数可以在API文档中通过Ctrl+F查询。
如果你想查询电脑的CapsLock和NumLock指示灯状态，可以通过函数LIB_UsbKbdCapsLockAndNumLockQuery()来查询
