Using Wio Terminal as a Mouse
This wiki introduces how to use the Wio Terminal as a simple mouse. This can be used to simulate mouse movements such as up,down,left and right. Furthermore left /right mouse button clicks, up/ down rolls can be implemented as well.
Installing Libraries
This example also requires an additional Arduino mouse library:
Visit the Arduino Mouse Library repository and download the entire repo to your local drive.
Now, the library can be installed to the Arduino IDE. Open the Arduino IDE, and click
sketch->Include Library->Add .ZIP Library, and choose theMouse-masterfile that you have just downloaded.
Complete Code
Please check the following code or from github here. Also, for more functionality, please refer to the official mouse functions from Arduino.

* 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.
