Problema Libreria Ethernet

alsky89 · June 23, 2015, 11:16am

Ciao a tutti, spero di far giusto.
io sto cercando di creare un programma per la gestione di tutta la casa via arduino.. una delle cose che mi sta facendo diventare matto è un errore della libreria Ethernet.h. ho provato a caricare anche uno sketch dell'esempio della libreria ma l'errore rimane. è questo:

/Users/Alberto/Documents/Arduino/libraries/Ethernet/Ethernet.cpp: In member function 'void EthernetClass::begin(uint8_t*, IPAddress, IPAddress, IPAddress, IPAddress)':

Qualcuno sa come risolverlo? vi ringrazio intanto.

Se non metti il codice che stai usando ... sarà difficile diagnosticare qualsiasi cosa ... :

Mi raccomando ... racchiuso negli appositi tag CODE come descritto al punto 7 del regolamento (il bottone è il primo a sinistra, quello fatto così : </>).

Ciao Guglielmo, ecco qui uno sketch che mi da l'errore.. tutti gli sketch ethernet mi danno lo stesso errore...

spero che riesci a darmi una risposta..
intanto ti ringrazio.

Che IDE usi? La libreria ethernet ufficiale è già nel core dell'IDE e quindi il percorso che si vede nell'errore che ti da è errato. In pratica questo: /Users/Alberto/Documents/Arduino/libraries/Ethernet/
Prova a togliere la cartella Ethernet da li (se non vuoi eliminarla del tutto, la sposti momentaneamente sul desktop) poi ricompili lo sketch e ti dovrebbe prendere quella che hai nel core... Se neanche così funziona riscarica l'IDE da capo.

alsky89 · June 24, 2015, 8:07am

ciao Marinaio67, ho provato ma lo stesso.. mi continua a dare gli stessi errori.. ho provato a cancellare le librerie ethernet, ricaricarla e copiarla di nuovo ma continua l'errore..

marinaio67 · June 24, 2015, 8:31am

Non devi copiarla di nuovo... è già nell'IDE... devi togliere la cartella di nome Ethernet che hai in /Users/Alberto/Documents/Arduino/libraries/

alsky89 · June 24, 2015, 8:46am

ma se la tolgo mi da questo:

sketch_jun24b.ino:6:22: fatal error: Ethernet.h: No such file or directory
compilation terminated.

quindi vuol dire che non c'è la libreria.

ora ho riscaricato arduino, riprovato a far partire lo sketch ma mi dice questo:

Sono punto a capo..

nid69ita · June 24, 2015, 9:08am

Più info.
Quale Arduino hai ?
Quale IDE hai scaricato ? Quale sistema operativo, windows, linux, mac ?

Domanda ovvia, ma... nell'IDE hai selezionata la board giusta ?
Appena provato con IDE 1.6.2 in ufficio da me e il codice che hai postato sopra mi compila (Win XP)

alsky89 · June 24, 2015, 9:11am

Risolto. Il problema era nella libreria SPI. cancellata quella ha cominciato a funzionare!
Vi ringrazio tantissimo!!!!!!

Ps. nid69ita arduino uno, 1.6.5 con sistema mac.

gpb01 · June 24, 2015, 9:52am

Spero che ora tu abbia capito che le librerie di SISTEMA non le devi aggiungere nella tua cartella delle librerie.

In quella cartella vanno SOLO librerie NON di sistema.

Per inciso, quelle di sistema (e che non devi toccare) sono quelle che trovi nelle due cartelle interne all'IDE :

/Applications/Arduino.app/Contents/Java/libraries
/Applications/Arduino.app/Contents/Java/hardware/arduino/avr/libraries
