안녕하세요.
WIZ550web 모듈은 SD card의 file을 관리하고 제어하기 위해 open library인 FatFs - FAT file system - 를 탑재하고 있습니다.
때문에 아래 링크의 [Application interface - File access] 부분을 참조하셔서 file의 create / open 및 read / write를 수행하시면 될 것으로 생각됩니다.
제품의 web server 동작 시, client(web browser)로부터 SD card에 저장된 web resource에 대한 요청을 수신하면 f_open 및 f_read를 수행하도록 구성되어 있습니다. 구현 시, 공개된 WIZ550web source code의 해당 부분을 참고하시면 좋을 것 같습니다.
