Description:
uVNC is a very small VNC server that can be run even on tiny 8-bit microcontrollers commonly found in small embedded devices. With uVNC, such devices can have a networked display without the need for any graphics hardware or a computer screen.

How'd this get started?:

Adam Dunkels: "It simply was a crazy idea: trying to see if I could squeeze a VNC server into a very, very small system. I already had my uIP TCP/IP stack for tiny embedded systems (http://www.sics.se/~adam/uip/) that would run with as little as a few hundred bytes of RAM (yes, hundred bytes). Being able to run VNC with something like a kilobyte of RAM seemed like a worthy challenge. After looking at the VNC protocol, it seemed to be possible to implement it using extremely small amounts of RAM. After a few days of coding, I had the first prototype working and released it on the website. I even had a demonstration server running on a colleagues Commodore 64.

About a month after the first release, I made a bugfix release and rebooted the demo server. Someone submitted a link to the Commodore 64 server to Slashdot, and the poor server was quite heavily loaded for a while. But it actually managed to survive the slashdotting, and ran happily for a week afterwards. I then had to turn off the server because I needed the hardware for other tasks."

What do you think are its best features?

"The best feature definitely is the small RAM requirements. I have been running the uVNC software, the uIP TCP/IP stack, the Contiki OS, a small GUI, a set of application programs, and device drivers, with as little as 2048 *bytes* of RAM. The desktop was very small - 120x56 pixels - but the important thing was that it worked! (See http://www.sics.se/~adam/contiki/ports/ for more information.)"
