Arduino Uno + enc28j60 - still not working
hello everyone,
i'm trying connect arduino uno enc28j60 ethernet module. wiring seems right (it made this:
the red , green led on ethernet module on, yellow led blinking
the router use d-link dir-300, standard firmware, ethernet cable enc plugged 1 of lan ports of router.
the library used ethercard, test sketch "backsoon" taken 1 of tutorials (so problem must not in code):
the device ip adress set 192.168.0.200 there's no other device ip, mac taken 1 of sketches (there must no devices such mac in network). gateway set same ip adress use open router control panel (is right?).
the result is, after [backsoon] serial monitor shows nothing, ends "dhcp failed". if use static ip (#define static 1), in serial monitor ip, gw , mac shown, same i've set previously, going ip browser (or pinging it) pc gives no result.
can me such issue? have read lot, , still haven't found useful case.
ps ide i've tried use 1.0.4 , 1.0
thanks.
paul.

do have link on router? (that's led on router showing there physical connection between 2 devices).
you don't need gateway if you're connecting lan.
