##Arduino TCP/IP SOCKET I had to create a project with TCP/IP socket connection. All other projects I found was a connection to Web sites, but the link was dropped after the connection. I added the ability to keep the connection open, but I didn't tried to connect to WEB pages (I don't need it).

##About the ENC28J60 ENC28J60 Ethernet Module utilizes the new Microchip ENC28J60 Stand-Alone Ethernet Controller IC featuring a host of features to handle most of the network protocol requirements. The board connects directly to most microcontrollers with a standard SPI interface with a transfer speed of up to 20MHz.

##What we have? We can do the following:

1. Open socket connection to socket server from arduino.
2. Send UDP packets
3. Listen to UDP.
4. Get NTP.
5. Connect with DHCP.
6. Connect to server with DNS name.

##How to use ###Set the ethernet you need to set MAC address: static uint8_t mymac[6] = {0x54,0x55,0x58,0x10,0x00,0x24};

###Set the socket: static uint16_t my_port = 11200; // client port

static uint16_t server_port = 1000; // server port

static uint8_t dest_ip[4]={192,168,1,105}; //server IP

###Start socket - in setup net.socketSetup(tcpSerialPrint,my_port,dest_ip,server_port);

the tcpSerialPrint is callback function on receiving data.

while (!net.connect()) {}

Serial.println("socket connected");

keep the socket alive - in the loop

net.process();

net.available()

##Next steps

1. Add the ability to connect web sits.
2. keep alive connection.
3. Re-transmission packets.
4. Connect to network with static address.
