Language (Programming) - Tylor's auxiliary storage

Libusb 를 Delphi에서 사용하기위해 usb.h 를 Delphi 용 코드로 변환을 완료하였습니다.

ADC 의 Eagle 칩에서 uClinux 를 사용할 때 U-Boot 와 uClinux(ADC 포팅버전)에서 USB를 통해 파일을 전송하는 USB Downloader 프로그램 대체하여 생산공정에 최적화된 소프트웨어를 만들었고, 테스트 결과 정상 동작하였습니다.

USB Downloader 를 대체할 수 있는 코드는 정리하여 연휴가 끝난 뒤 포스트하도록 하겠습니다.

추가로 이 코드를 사용하기 위해서는 libusb0.dll 이 필요합니다.
libusb-win32 는 http://libusb-win32.sourceforge.net/ 에서 받으시면 되고, 예제는 libusb-win32 내에 예제를 참고하시면 됩니다.
