我用 PlatformIO 下载了最新版本的 VS Code，我还从 PlatformIO 库管理器下载了库 Mouse.h，即便如此，在我将代码上传到我的 Micro Pro 后，鼠标对操纵杆没有响应！但是当我通过 Arduino IDE 上传时，同样的代码可以工作！
我将 .platformio/lib 中的 Mouse.h 与 program files\Arduino\libraries 中的 Mouse.h 进行了比较 我将 .platformio/lib 中的 Mouse.cpp 与 program files\Arduino\libraries 中的 Mouse.cpp 进行了比较
他们有完全相同的代码！
这是我的 MICRO PRO 32u4 5v 的代码：

This is very simplistic code that allows you to turn the
SparkFun Thumb Joystick (http://www.sparkfun.com/products/9032)
into an HID Mouse. The select button on the joystick is set up
as the mouse left click.
