Wiimote Library
Wiimote Library 내용을 알아야 응용프로그램을 만들 수 있기 때문에 라이브러리 내용을 살펴보도록 하겠다.
위모트 라이브러리는 C#으로 작성되어 있고, Wiimote.cs, HIDImports.cs, Events.cs, DataTypes.cs 네가지 파일로 구성된다.
Wiimote.cs는 wiimote class가 있고 위모트를 연결하고 동작하기 위한 Method 들을 포함하고 있어서 , 윈도우프로그램에서 초기화와 데이터입출력을 처리하는 부분이 된다.
HIDImports.cs는 인식된 위모트를 연결해주는 역할을 하고, Events.cs는 이벤트 처리에 해당하는 부분이고, DataTypes.cs는 데이터처리에 필요한 구조체들을 정의하고 있다.
각 해당 파일에 대한 클래스와 메소드를 정리해 보았다.
