| ...if (ether.begin(sizeof Ethernet::buffer, mymac, 53) == 0) { Serial.println(P("Failed to access Ethernet controller")); } else { Serial.println(P("Ethernet is fine and up")); }... |
Pentru a functiona, in loc de litera P trebuie pus F.
De asemenea, si in libraria Ethercard se mentioneaza acest lucru si prezinta comanda de trecerea a pinului 8 in 53:
VCC - 3.3V
GND - GND
SCK - Pin 52
SO - Pin 50
SI - Pin 51
CS - Pin 53 # Selectable with the ether.begin() function
# The default CS pin defaults to 8, so you have to set it on a mega:
ether.begin(sizeof Ethernet::buffer, mymac, 53)
Din pacate, la teste nu reuseam sa-l fac functional si renuntasem... dar Luci, un coleg mai rabdator, a cautat si el pe net si a dat de filmuletul Arduino EthernetShield ENC28J60 Configuration - Parte1

La adresa locala data de mine, 192.168.0.199 gasim 2 situatii:
In montaj eu am mai pus si pinul de RESET...
