What does it take to run basic web server. Actually not much – Ethernet controller, MCU and some code. Rob has posted his webserver project based on MSP430 microcontroller and WIZnet W5200 Ethernet controller IC. This controller has hardware TCP/IP stack and other necessary support so that controlling it becomes pretty easy task.
This tiny web server can do a lot. For instance as a simple demo it dumps MSP430 memory in to webpage. If you interested in more serious functionality there are also couple handy features allowing to read data from pins and control devices over the net. The total cost of this device is about $10 – ideal solution for low budget ideas.
