Hi,
I am making a board for toggling relay remotely with enc28j60.
The relay is connected to Contactor for handling more current, The relay is connected to mcu(Atxmega64a3) with optoocouple and transistor.
I had a problem which after some toggle I see enc28j60 wont reply anymore, I put a _delay_ms(x) after each toggle which seems help on this device , but when I put two device the second one has this problem when the first one toggle ports.
I think some spike or ... making this problem but don't know how to prevent it.
Thanks in advance
