Contec 사의 GPIB 카드 (GP-IB(PCI)F) 제어를 위한 Class (C#)
Software/C#2023. 1. 19. 13:53
반응형
일본 Contec 사의 GPIB 통신 카드인 GP-IB(PCI)F 를 사용하기 위한 Class 입니다. C++ 로 제작되어서 제공되는 DLL 라이브러리를 사용합니다. Contec 사에서는 C#을 위한 별도의 라이브러리는 제공을 안하고 DLL을 사용한 예제 코드만 제공합니다.
DLL 파일은 올려둔 파일을 사용하시거나 제공받은 CD에서 드라이버를 설치하시면 찾을 수 있습니다.
여기서는 통신에 꼭 필요한 기능만 멤버 함수로 만들었습니다. 필요한 부분은 더 추가하셔서 만들어 쓰시면 되겠습니다.
