In summary, the eZ430-Chronos is a very flexible wireless development platform contained within a watch case. The Chronos is a low cost system that will enable the user to create innovative, wireless applications that can be controlled directly from the wrist. It includes all the hardware and software needed to create full blown systems with only a single kit. Open-source software is available that can be used as a foundation for an application or to inspire a creative idea. The Chronos is based on the CC430, a sub-1GHz RF system-on-chip microcontroller which directly controls the 96-segment LCD display. When buttons are pushed it is capable of beeping or sounding an alarm and includes a backlight for use at night. The Chronos is capable of acting as the hub for nearby wireless sensors. With the included USB-based wireless Access Point it is able to transfer data to a PC wirelessly. Chronos is available in three different frequency bands, 433, 868, and 915MHz, allowing it to work worldwide. It is important to note that Chronos is a development tool, not an end product. Because the user is allowed to modify the code running on the watch, it is not FCC certified; but it could pass FCC certification when loaded with the appropriate firmware. Real-time debugging and programming of the Chronos is possible using the eZ430 programmer by removing the inner electronics from the watch case and then connecting it to the programmer. It is also possible to load new programs wirelessly to the Chronos using the wireless update feature.
