The ISA-Ctrl PCB
Build your own simple and cheap webserver!

 

The ISA-Ctrl-PCB is a Mini-Webserver based on AVR-MEGA32.
With the webserver you can get access to the AVR-Controller by an Internet-Browser.
Now you can control external peripherals from the internet.
Or see the status of different sensors of your house from anywhere in the world!

You just need our PCB and the (inexpensive) parts and an old network card.

It is related to a project of Ulrich Radig (http://www.ulrichradig.de).
(if you use the source of Ulrichs page, you have to set the ISA_CTRL compiler switch)


Ready compiled HEX-Files for the webserver are available in the
Download-Section.....

In the mikrocontroller.net-Forum is a big thread (in German): Here...

The ISA-Ctrl PCB contains an ISA-Slot to connect a NE2000-compatible Network-card.

Supported are Networkcards with Realtec RTL8019 or 3COM (3C5x9) chip-sets.
(If you use a 3Com-Card see Details here...)


The homepage files can be stored directly in the ATMEGA32 or on SD-/MMC-Cards.

Here are screenshots of a Webserver page...

 

The LED is switchable now :

Access your webserver from the Internet!

You want to access your webserver from the Internet, but you don't have a fixed IP-Address?

--> Use a DynDNS-Service

Than your Webserver can have an address like:

http://mywebserver.dyndns.org

And you have to tell your router, where to route the port 80 (http) --> to the IP of your webserver e.g. 192.168.1.66

Finished!

Assembled PCB
