Hi All,
I am using Atmega128RFA1 and its evaluation kit STK 600 and trying to interface it to wiz811MJ ethernet network module which include w5100 ethernet controller.
I have to configure Atmega as master and the ethernet controller module as slave using SPI interface .
My doubts:
How to I power Up the ethernet module ?? is 3.6 v battery fine?? or i need to connect an external volatage regulator of 3.3 v ??
Anything else i need to check ?? or external components ??
after this is done I wil program intiialize the w5100 chip and its registers.
