Hello! I am currently using ethernet shield enc28j60. I am using the web client example of UIPEthernet.h library. I have tweaked the example and have successfully send data from my arduino into a database in the internet. However, i have trouble in making a sketch that can serve as an ethernet shield functioning as a web client and as a web server at the same time. I need to retrieve a value from my database so I can control a led in my arduino. I found a working sketch i can use to control a led over the internet, the code is below
#include <UIPEthernet.h>
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte ip[] = {
192,168,254,113
};
EthernetServer server(2222);
int LED = 6; //
void setup()
{
Ethernet.begin(mac, ip);
server.begin();
pinMode(LED, OUTPUT);
}
#define BUFSIZ 100 //Buffer size for getting data
char clientline[BUFSIZ]; //string that will contain command data
int index = 0; //clientline index
void loop()
{
index=0; //reset the clientline index
EthernetClient client = server.available();
if (client) {
boolean currentLineIsBlank = true;
while (client.connected()) {
if (client.available()) {
char c = client.read();
if(index<BUFSIZ) //Only add data if the buffer isn't full.
{
clientline[index]=c;
index++;
}
if (c == '\n' && currentLineIsBlank)
{
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println();
client.println("<h1><center>LED Control</h1></center>
<center><form method=get action=/?><input type=radio name=L1 value=1>On
<input type=radio name=L1 value=0>Off
<input type=submit value=submit></form></center>");
break;
}
if (c == '\n') {
currentLineIsBlank = true;
}
else if (c != '\r') {
currentLineIsBlank = false;
}
if(strstr(clientline,"/?L1=1")!=0) { //look for the command to turn the led on
digitalWrite(LED, 1); //turn the led on
} else if(strstr(clientline,"/?L1=0")!=0) { //look for command to turn led off. Note: If led is on, it will stay on until command is given to turn it off, even if multiple computers are on the site
digitalWrite(LED, 0); //turn led off
}
}
}
delay(1);
client.stop();
}
}
Is it possible to modify this UIPEthernet.h library's example so i can make my ethernet shield to work as a web client and as a web server at the same time?
