예제의 아이피찾는 코드 업로딩 후, 코드확인 했고 cmd ping으로 체크도 해봤는데 이상이 없었습니다.

하지만 예제에 입력했을때

byte mac[] = {  0x74, 0x69, 0x69, 0x2D, 0x30, 0x5};

IPAddress ip("192,168,35,94");

// IP 주소는 " XXX,XXX,XXX,XXX " ',' 주의해주세요.

// 이더넷 라이브러리 초기화

// 사용할 IP 주소 와 포트 입력

// ('port 80' 은 HTTP 의 기본 값 입니다.):

EthernetServer server(80);

이 부분에서 컴파일 오류가 발생합니다.

이런식의 코드가 발생하는데, 글자수가 일치하지 않는다는 것 같은데 어떤 식으로 수정하면 될까요.
