eZ430-Chronos Watch Data Logger

3.4 eZ430-Chronos Watch Data Logger

Besides the sports watch software, the eZ430-Chronos kit comes with an additional software project that

turns the watch into a data logger. Heart rate,

(5)

temperature, and altitude can be logged in user definable

intervals of 1 to 255 seconds. 8KB of flash memory is reserved for logging several hours up to days,

depending on the settings. The stored data can be transferred to a PC (in CSV format) and used for

further analysis. The data logger provides fewer features compared to the sports watch software as

memory is freed for data storage. Most importantly, no Set Functions are available (that is, the watch

cannot be set or calibrated standalone); however, this can be done conveniently by using the

eZ430-Chronos Data Logger PC software. The software project for CCS can be found in C:\Program

Files\Texas Instruments\eZ430-Chronos\Software Projects\CCS\Data Logger and for IAR in C:\Program

Files\Texas Instruments\eZ430-Chronos\Software Projects\IAR\Data Logger.

Available features:

• Time, Date

• Temperature

• Altitude

• Heart rate

• Sync

• Wireless firmware update

• Data logger

• Battery monitoring

NOTE: No Set Functions are available in this software. All settings can be done using the

eZ430-Chronos Data Logger PC software.

User concept:

The user concept and the modes remain the same as in the sports watch software except for the Set

Functions (see Section 2.1).

Heart rate can be generated by eZ430-Chronos Control Center. Optional heart-rate monitor is available from BM innovations at
