hallo,
ich benutze ein arduino mega board 2560 und ethernet shield arduino.
ich hab im software alles richtig eingegeben: feste ip adresse, mac vom shield, und vom server:
byte ip[] = { 141, 100, , };
byte subnet[] = { 255, 255, 255, 0 };
byte gateway[] = { 141, 100, 102, 254 }
initialisiert mit...Ethernet.begin(mac, ip, gateway, subnet);
die verbindung wird aber trozdem nicht hergestellt.
die leds link, 100M, FULLD. leuchten immer.
led RX leuchtet auch.
led TX leuchtet aber nie.
Frage: woran kann es liegen?
ich freue mich auf Feedback.
Gruß

Du hast keine MAC-Adresse angegeben!
Code:
byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
Schreib das noch vor die IP, dann sollte es gehen. Hab jetzt nur auf die schnelle ma geschaut. Müsstes aber sein
