Preface
This is a circuit module for the web need not be expensive to show this little project. A complete mini web server for about 35 €. In the microchipENC28J60 Ethernet Controller comes in conjunction with an ATmega32 or ATmega644 used. It comes from the circuit without SMD components. Thisensures that the mini web server can be reproduced by any hobbyist without further ado. As a replacement for a current PC or Network AttachedStorage (NAS), this server is not thought of. In principle, this would be possible, but it is not here faster than ISDN speed on the road. To view a 2-4-KBwebsite / homepage for shift and sway, but it goes forever.

Schematic
RS232 interface
The serial interface has the following settings (HyperTerminal):
On the board is a 9-pin connector that can not be replaced by a 9-pin connector. By default, Irecommend a 1:1 RS232 extension.
1:1 RS232 cable connector /
male null modem cable x TXD RXD
Create from the Web server source code Hexfile
With the installation of WinAVR a useful tool Programmers Notepad 2 is installed shortlyPN2. This program will open it on the taskbar.
Next, the project file of the project will open in PN2, the project files) have the fileextension (*. pnproj. Now we find the project under the Open Content (Standardinstallation) Mark on the left side in column (1) again. Now you should still a file from theproject which is tabulated in (1) appears to be opened. It is to be the best filemain.c. Double-clicking in the project overview (1) is sufficient to do so. The file will nowappear in a new window (2). Only now can be accessed 3) on the control bar on Tool /[WinAVR] Make All (. Make All created now a Hex file that can be flashed into the AVR.Flashing the Hexfiles may also be from the PN2.
In MAKEFILE CPU type and details are available for programming hardware. I use as aprogrammer always the STK200 to the LPT1, this is my cable which I have described underBaseKit (minimal solution for use with four resistors). In another programmer that has to bespecified in the makefile, should be programmed from the PN2. If the programming via anexternal tool such as PonyProg the definition of the programmer in makefife deleted.
