Hello Arduino Forum, I'm looking for Information on how to hook up an ethernet shield to an Atmega328 Chip without the Arduino Board. Also I'm asking you to excuse my bad english :)
I'd like to water my Plants over the Internet and I don't want to waste my beloved Arduino Board to the system. The Problem as I see it is that the ICSP header, according to the Arduino uno schematics, is connected to an Atmega8U2-MU (which i'm guessing is part of the Arduino board) and i don't have this chip in my barebone-project.
Googling the subject brought me to http://zaujimave.info/arduino-nano-ethernet-shield-wo-sd/index-en.htm but i'm not sure if that works with an atmega328 too and i'm afraid that i will kill my board while experimenting. I tried to hook up the ICSP pins of the Shield like this: 1: D12; 2: +5V; 3: D13; 4: D11; 5: (nothing because i guessed i wouldn't need another reset button); 6: GND. The shield got power and also the LEDs indicated that there is an internet connection but i couldn't get a ping signal. Is there anything i did wrong?
I've read that Pin 4 and 10 somehow activate or deactivate the SD/Ethernet function - do i have to hook those up to the Shield? It also said something about setting them to output and HIGH to deactivate the corresponding feature but the information was ambiguous. Can somebody set this right for me please? (i'm not planing on using the sd slot) So does anybody know how to hook up the ethernet shield directly to the atmega328 the right way?
I got the shield for cheap on a flea market and i don't think it's an official arduino product - there's no prduct name written on it. All i can say is that it looks like this: http://kll.engineering-news.org/kllfusion01/downloads/ArduinoEthernetShield.jpg just without the Arduino TM logo on the upper left corner - cheap chinaware i guess so it maybe wasn't that good of a price as i was thinking while buying it :(
Thanks in advance!
