Hi guys!!
I’m stuck on a really simple webserver using the Webduino library.
Just a few words about it: This server turns ON and OFF a relay, with url commands like “192.168.x.x/R1=ON” or “192.168.x.x/R1=OFF”. and everything works fine. Then i tried to get some variables in the same way,setting up their name and their values in the URL and parsing it to store these variables . For example, i tried to store a variable with the value of a temperature setpoint, with the command “SETCOLD12” ( complete url : 192.168.x.x/SETCOLD12)
To do that, i used strings.By default, the sketch saves a string with the url parameter after the numeric address ( in the first examples url_param is “R1=ON”) , then i tried to ‘split’ this string to get a code (SETCOLD) and a value (12) using string.substring() method to split them, and string.toInt() to save the setpoint value in a variable.
Compilation is OK, but when i upload my sketch to arduino UNO + Ethernet , the servers drops down. 192.168.x.x is no more reachable ( everything was ok before implementing this strings) , and RX pin on ETH shield is continuosly lighted up.
When it works, user and pass to authenticate are : user=ciccio password=pino
Here’s my code:
#include <Ethernet.h>
#include <SPI.h>
#include <WebServer.h> //libreria webduino
//Mac address and IP address
static byte mac_Add[] = {0x05, 0xA3, 0xBB, 0xCC, 0xDE, 0x02 };
//my IP
static byte ip_Add[] = {192, 168, 1, 36 };
//creazione oggetto Webduino

Can someone help me getting reed of this problem?
