| The web pages you are watching are served by a <a |
| href="http://dunkels.com/adam/contiki/apps/webserver.html">web |
| server</a> running under the <a |
| href="http://dunkels.com/adam/contiki/">Contiki operating system</a> |
| on a small <a |
| href="http://www.inf.fu-berlin.de/inst/ag-tech/esb/english/">sensor |
| board</a> developed by <a |
| href="http://www.inf.fu-berlin.de/inst/ag-tech/">the CST group</a> at |
| <a href="http://www.fu-berlin.de">FU Berlin</a>. The sensor board is |
| equipped with a TI MSP430 micrcontroller with 2048 bytes of RAM and 60 |
| kilobytes of flash ROM, as well as a number of sensors. The sensors |
| can measure vibration, temperature, IR-light, sound, tilt and motion. |
| </p> |
| |
| <h2>Internet connectivity</h2> |
| <p> |
| The sensor board is directly connected to the Internet through the |
| RS232 interface on the board, and is running the <a |
| href="http://dunkels.com/adam/uip/">uIP TCP/IP stack</a> on which |
| Contiki is based. |
| </p> |
| |
| <h2>Memory usage</h2> |
| <p> |
| The entire Contiki MSP430 system uses only about 1800 bytes RAM, of |
| which 280 bytes is used for the virtual screen and 300 bytes for |
| network buffers. All code and web pages are stored in the |
| microcontroller's on-chip flash ROM. |
