Please read first this Article:

Getting started with Arduino and WIZ820io http://wiki.mcselec.com/Getting_started_with_Arduino_and_WIZ820io


It uses the same source code exept we use here an Wiznet W5100 Chip intead of W5200 so only config TCPIP needs to be changed.

The usage of Easy TCP/IP in combination with that example is also the same.


The used Ethernet Shield is this here: http://arduino.cc/en/Guide/ArduinoEthernetShield


Another difference is that in this example we do not use the Bascom-AVR bootloader. We use here the existing Arduino bootloader.

To get started with this see here:  http://wiki.mcselec.com/Getting_started_with_Arduino_UNO

Source Code:

The difference is only this part in the Bascom source code:


'Here you need MAC address, the ip address you like to use, subnet mask, gateway and localport
 Config Tcpip = Noint , _
 Mac = 1.1.94.127.1.255 , _

 Submask = 255.255.255.0 , _
