Texas Instruments eZ430-Chronos Wireless Watch
Introduction
From TI's EZ430-Chronos Wiki Page:
The eZ430-Chronos is a highly integrated, wearable wireless development system that comes in a sports watch. It may be used as a reference platform for watch systems, a personal display for personal area networks, as a wireless sensor node for remote data collection, or simply as a watch.
Based on the CC430F6137 <1 GHz RF SoC, the eZ430-Chronos is a complete CC430-based development system contained in a watch. This tool features a 96 segment LCD display and provides an integrated pressure sensor and 3-axis accelerometer for motion sensitive control. The integrated wireless feature allows the Chronos to act as a central hub for nearby wireless sensors such as pedometers and heart rate monitors. The eZ430-Chronos offers temperature and battery voltage measurement and is complete with a USB-based CC1111 wireless interface to a PC.
The eZ430-Chronos watch may be disassembled to be reprogrammed with a custom application and includes an eZ430 USB programming interface.
Purchasing
The eZ430-Chronos watch can be purchased directly from TI for $49. The watch works out of the box with this plugin and does not require any custom firmware or additional hardware.
Functionality
This plugin currently provides access to 3 of the watches hardware buttons: *, #, and UP (depicted with an upwards pointing arrow on the watch). Upon installation, the plugin defines a new device which displays the current status of the buttons:
Pressing one of the above 3 buttons on the watch toggles the device's corresponding button state. The button states can be directly used to trigger events:
The watch offers plenty more, including an integrated 3-axis accelerometer, temperature sensor, and pressure sensor. If there is enough interest, I may add support for these features in the plugin.
Installation
Hardware & Driver
Before setting up the plugin, a driver for the watch's USB dongle must be enabled.
- Locate the USB RF dongle supplied with the watch (the object in the lower right corner of the image above), and plug the dongle into one of the USB ports on your Vera device.
- If you have not already, enable SSH access to your Vera, and establish an SSH connection (see http://wiki.micasaverde.com/index.php/Advanced_Commands).
