MAC address help!

Hey guys!

please help! i have an ethernet shield connected to my Arduino 1:
the sticker for the MAC address reads: “90-A2-DA-0D-A8-AF”

in this code, what do i put for the mac address? i get
“DhcpAddressPrinter.ino:22:24: error: invalid suffix “D” on integer constant” error and other
“hcpAddressPrinter:22: error: ‘DA’ was not declared in this scope” errors if i put “90,A2,DA,0D,A8,AF” for the MAC address???

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = {  
  0x00, 0xAA, 0xBB, 0xCC, 0xDE, 0x02 };


You need to type it like it is in the example:

byte mac[] = {  0x90, 0xA2, 0xDA, 0x0D, 0xAF, 0xAF };

The MAC address is a set of 6 bytes (8 bit numbers between 0 and 255). The notation used is called hexadecimal/base 16 ( It's commonly used because each hexadecimal digit is represented by 4 bits, so a 8 bit byte is two hex digits, e.g. A2 which is 10*16+2*1=162.

ok, thank you!! :)
