eZ430-Chronos Software
3.1 Overview
This chapter describes the software that is included in the eZ430-Chronos kit. Different projects and PC
user interfaces are available:
1. eZ430-Chronos sports watch software
2. Control Center PC software for Windows and Linux
3. eZ430-Chronos watch data logger
4. Data logger PC software for Windows and Linux
Many features of the eZ430-Chronos kit are based on TI's SimpliciTI protocol stack. However, the eZ430-
Chronos watch can also be used as a heart rate monitor. For this purpose, the BlueRobin™ ultra-low-
power protocol stack can be used.⁽¹⁾ is implemented on the watch and USB access point. The protocol
stacks are selected automatically, depending on which feature is used.
3.2 eZ430-Chronos Sports Watch Software
The sports watch firmware (default) provides a broad set of features. Besides basic watch functions such
as time, date, alarm and stopwatch advanced sports watch features such as an altimeter, heart rate
monitor*, calorie*, vertical speed* and distance information* are available. The internal accelerometer
provides acceleration data on the watch LCD and allows controlling a PC by transferring the sensor's
measurements. The watch can also be used to control PowerPoint or other PC software with its buttons.
User concept:
The different features are either available in the top or bottom LCD line.
There are three user modes available: Modes such as Time or Date,... , Secondary Functions, which
allow (de-)activation of features (for example, to start or stop the stopwatch, enable/disable alarm, etc.),
and the Set Functions, which allow changing settings (setting time, date,...) or resetting the stopwatch for
example (see Figure 3-1).
• Modes: The different modes can be selected by using the button left of the corresponding LCD line.
Examples:
The "*" button allows selecting the top line mode
The "#" button allows changing the bottom line modes
• Secondary Functions: Secondary functions provide an extension to the selected mode and are
available through the button to the right of the corresponding LCD line.
Examples:
Toggling between time (HH:MM) and seconds (.SS) in time mode: push "UP" button to toggle between
modes.
Start/Stop in stopwatch mode: push "DOWN" to start or stop stopwatch
• Set Functions: Time, date and other options can be set by holding the button left of the corresponding
LCD line.
Examples:
Setting the time (shown in top LCD line): hold the "*" button to enter the time set menu.
Resetting the stopwatch (shown in bottom LCD line): hold the "#" button to reset.
