将Wio Terminal用作鼠标
本 wiki 介绍了如何将Wio Terminal用作简单的鼠标。可以使用它来模拟鼠标的上下左右移动，以及左/右鼠标按钮点击和滚动。
安装库
此示例还需要一个额外的Arduino鼠标库：
访问 Arduino 鼠标库 存储库，并将整个存储库下载到本地驱动器上。
现在，可以将库安装到Arduino IDE中。打开Arduino IDE，点击
sketch->Include Library->Add .ZIP Library, 然后选择刚刚下载的Mouse-master文件。
完整代码
请查看以下代码或从 此处的GitHub获取， 此外，要获取更多功能，请参考Arduino官方的 鼠标函数。
/*
* A demo for Wio Terminal to simulate mouse by buttons.
* Such as Mouse Up, Mouse Down, Mouse Left, Mouse Right,
* Click the left mouse button, Click the right mouse button,
* Up roll, Down roll and etc.

*
* Usage(in Wio Terminal):
* Press the WIO_5S_UP --------------------> Mouse Up
* Press the WIO_5S_DOWN --------------------> Mouse Down
* Press the WIO_5S_LEFT --------------------> Mouse Left
* Press the WIO_5S_RIGHT --------------------> Mouse Right
* Press the BUTTON_3 ------------------------> Click the left mouse button
* Press the BUTTON_2 ------------------------> Click the right mouse button
* Press the WIO_5S_PRESS and WIO_5S_UP ----> Up roll
* Press the WIO_5S_PRESS and WIO_5S_DOWN ----> Down roll
*
* Some tips:
* 1. If your PC unables to recognize USB device leading the Wio Terminal can’t work.
* You can solve this problem through updating your ArduinoCore.
