cassyarduino 0:e3fb1267e3c3 2 * UIPEthernet TcpClient example.
cassyarduino 0:e3fb1267e3c3 3 *
cassyarduino 0:e3fb1267e3c3 4 * UIPEthernet is a TCP/IP stack that can be used with a enc28j60 based
cassyarduino 0:e3fb1267e3c3 5 * Ethernet-shield.
cassyarduino 0:e3fb1267e3c3 6 *
cassyarduino 0:e3fb1267e3c3 7 * UIPEthernet uses the fine uIP stack by Adam Dunkels <adam@sics.se>

cassyarduino 0:e3fb1267e3c3 9 * -----------------
cassyarduino 0:e3fb1267e3c3 10 *
cassyarduino 0:e3fb1267e3c3 11 * This TcpClient example gets its local ip-address via dhcp and sets
cassyarduino 0:e3fb1267e3c3 12 * up a tcp socket-connection to 192.168.0.1 port 5000 every 5 Seconds.
cassyarduino 0:e3fb1267e3c3 13 * After sending a message it waits for a response. After receiving the
cassyarduino 0:e3fb1267e3c3 14 * response the client disconnects and tries to reconnect after 5 seconds.
