Problemi misura di Temperatura con sonda DS18B20

[davrigo]

Ciao a tutti, sto cercando di leggere da una sonda DS18B20 in valore di temperatura, per poi scriverlo su di una pagina web.
Fino alla lettura tutto ok, la vedo sulla seriale, ma quando cerco di aggiungere le componenti ethernet allo scketch (Ethernet.begin(mac, ip) sulla seriale mi compare la scritta "NO MORE ADRESSES"

Mi sapete per cortesia dare una mano non so piu dove sbattere la testa.

Grazie

Sketch, schema e indirizzo dove mandarti un tecnico...

Ciao posto solo un parte del codice xk è troppo grande, comunque l'errore risiede nella prima parte

Non si capisce niente.
Se hai la Ethernet non devi usare i pin 10, 11, 12, 13 e possibilmente neanche il 4.
Questo su Arduino UNO. Con altre schede bisogna verificare caso per caso.

Grazie gentilissimo, appena riesco provo a cambiare ingresso.
