How i upload web page from sd card of ethernet shield w5100 for control leds?I make it without sd card and library and work but for many leds ...for big site buffer is small and i want to upload from a sd card ....any idea?
#include <SPI.h>

byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
byte ip[] = {192,168,1,15};
const byte Port = 80;
Server server(Port);
int counter=0;
char c;
word xClicksProcessed=0;
char codeOK='0';//start Code is blank....

// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
server.begin();

//operation via serial monitor

digitalWrite(IR_PIN4,LOW);
