The source code for this project is installed by Chronos-setup.exe. By default, the source code is copied to C:\Program Files\Texas Instruments\eZ430-Chronos\Software Projects
The eZ430-Chronos can be used as a data logger. Heart rate, temperature, and altitude can be logged in user definable intervals of 1 to 255 seconds. 8kB of internal Flash memory is reserved for logging for 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 source code for this project is installed by Chronos-setup.
Lucid Scribe is a performance monitor for your Self, designed to detect REM sleep and trigger audio tracks. It has a plugin for the chronos, but more sleep research data is needed on the Lucid Scribe Project to complete the rapid eye movement detection algorithm.
The code examples are a series of ~100 sample programs written in C that demonstrate several ways to configure each of the peripherals on the CC430. Using CCS or IAR, each file can be downloaded directly to the device or snippets from each example can be combined to achieve your desired function.

Wireless Update (RF BSL)
The Wireless Update feature allows you to change the firmware on the Chronos wirelessly. There will be no need to open the enclosure to upgrade the program in use. Hardware debugging (setting breakpoints, single stepping, etc) is not possible over a BSL because physical access to the JTAG/Spy Bi-Wire is required for in-system programming.
All eZ430-Chronos produced after April 2010 will include this feature. The production code is found on the bottom of the box. However, earlier kits have to be manually updated to support the wireless Update.
How to update eZ430-Chronos to support the Wireless Update:
- Update your Chronos watch. Please download the eZ430-Chronos Firmware Update Tool from BM innovations at:
- Extract the files
- Open watch, remove battery and connect to emulator (see eZ430-Chronos user guide for details)
- Connect emulator to PC (Either Code Composer Studio or the IAR Embedded Workbench must be installed to obtain the drivers)
- Select script according to local frequency
- Click RUN
- Update the USB access point (requires the CC-Debugger and SmartRF programming interfaces) - Only necessary for kit built before April 2010:
- Solder 5 wires onto the RF access point as described in the Chronos user guide
- Download and install SmartRF Flash Programmer
- Connect access point to emulator and the emulator to PC
- Press "Reset" button on CC Debugger, LED will turn green
- Open .hex file in SmartRF Flash Programmer according to frequency
- Select option "Erase, Program and Verify" and click "Perform Action"
- Updating Software on the watch:
- Open Control Center
- Select "Wireless Update" tab
- Open .txt file e.g. Datalogger in directory: C:\Program Files\Texas Instruments\eZ430-Chronos\Recovery\Chronos Watch\Applications
- Only transfer flash images to the watch, which allow invoking the updater software on the
- watch. The file to be downloaded to the watch must be in TI-TXT format to work with this update
- procedure. This new firmware must reside within the main memory flash (0x8000-0xFFFF),
- otherwise the update procedure fails due to boundary checks on the watch side.
- Click "Update Watch"
- Push "#" on the watch until "rFbSL" is shown on the LCD
- Push "*" to activate update
The watch will show "RAM" for a short time. During that time, a part of the update software will be transferred to the RAM of the CC430 on the Chronos watch. Once this was finished, the actual code will be transferred, the progress will be shown in percent.
OpenChronos is a modular firmware for the EZ430-Chronos, primary designed to be compiled with the msp430-gcc. Features can be configured with "make config" to save space and add additional components.
These programs have been tested in Windows, Linux, and Mac OS X.
By default, the programs are setup to run in Windows. You must change the COM port number to the COM port your wireless access point is assigned to in the code for the programs to work correctly. The directions for this are in the source code, so see the source code for details.
To get the programs working in Linux both programs have a line in the code that says:
ser = serial.Serial(5,115200,timeout=1)
change that line to:
ser = serial.Serial("/dev/ttyACM0",115200,timeout=1)
If another USB device attached to the machine the device may be /dev/ttyACM1, /dev/ttyACM2, etc.
or in OSX: Get pySerial (http://sourceforge.net/projects/pyserial)
ser = serial.Serial("/dev/tty.usbmodem001",115200,timeout=1)
If you get this console error, it means the access point dongle is not plugged in. If everything was loaded successfully once, a more informative dialog box is popped up in this case.
bad option "-mode": should be one of -blocking, -buffering, -buffersize, -encoding, -eofchar, or -translation while executing
Once plugged in, you should get a dmesg log entry like this (Linux 2.6):

Interval Training Application Example Using State Machine Design
This application example implements interval training utilities on the TI Chronos Watch using IAR visualSTATE and IAR Embedded Workbench for MSP430. It monitors heart rate and manages work and rest intervals. The application consists of an IAR visualSTATE project and an integrated IAR Embedded Workbench project. The projects can be built using code size and state limited versions of the tools available for free from IAR Systems website, still leaving enough room for modifications and additions to the source.
Battery Monitoring and Low Voltage Level Handling Application Example
This application example builds on the Interval Training example but is slightly more complex and adds battery monitoring and low voltage handling functionality. It also introduces the concept of parallel regions in the state machine.Watch the video!.

Compatible RF Development Boards
- AMB8423 eZ430 868/915MHZ target board based on CC1101 and MSP430F2274
- EM430F6137RF900 CC430 Wireless Development Board
- CC1101EMK433 CC1101 433 MHz Evaluation Module
- CC1111EMK868-915 CC1111 868/915 MHz Evaluation Module. This is similar to the USB Chronos Access Point except for minor differences in the schematic. It also includes additional headers and for reprogramming using the CC Debugger.
- CC1110DK-MINI-868 CC1110 Mini Development kit
- MSP430-CCRF Olimex MSP430-CCRF (should work, I've ordered the board and will test soon) 868/915MHz
- EZ430-F2013 Is exactly the same as the FET (programmer stick) that comes with the watch (except for the case). So the EZ430-T2012 can be programmed, debugged, flashed ect. as wel, have tested it.This is interesting for the 433MHz watch, 433MHz RF modules are very cheap like TX433N, RX433N less than 10 euro, and easy to connect to a EZ430-T2012 Since 433MHz is not highly supported by TI and BM its very highly supported elsewhere and its the cheapest. Indoor/outdoor weather stationa, wireless doorbells.. ect.. almost always use 433MHz.The 433MHz version is the best choice for students and hobbyist I think (for experimenting).
- panStamps are small Arduino modules with a CC1101 RF frontend for the 868/915MHz ISM bands. panStamps share the same protocol (SWAP) as OpenChronos-NG so the chronos watch (with OpenChronos-NG) can be used to read panStamp sensors and control panStamp actuators.
There are several options to get support for the Chronos:
433, 868 & 915 MHz Frequency Differences
There are 3 different versions of the eZ430-Chronos kit available, the eZ430-Chronos-433, -868, and -915. The only difference between each version is the RF operating frequency that is supported out-of-the-box. Having multiple operating frequencies available allows for the Chronos to comply with regional RF regulations worldwide. If you're debating on which version is best, it's recommended that you purchase the version that was designed for your specific region.
Theoretically, the biggest impact of changing the radio frequency is range. In general, radio frequency is inversely proportional to range. Low frequency signals travel a greater distance and penetrate through and around objects better than high frequency signals. On the other hand, lower frequencies require larger antennas due to the longer wavelength. In the case of the Chronos, the 868 and 915MHz version will have similar RF performance. Evaluation on the 433 MHz version is on-going, but the range is likely to be shorter as a 433MHz antenna can't be much bigger inside the watch housing compared to the other versions. More information will follow once results are available.
Because each version is based on the CC430F6137, most of the other RF performance features are functionally the same on each version. Power consumption, bandwidth, data rate will be identical for each version. The data rate is independent of the radio frequency so it's possible to achieve the max data rate of 500 kbps using any Chronos version.
The 868-MHz and 915-MHz watch hardware are physically identical and the radio frequency is software selectable so it's possible to switch frequency if necessary. However, the RF Access Points for the two respective kits are slightly different. The 868-MHz Access Point has a 0Ω resistor next to the antenna and the 915-MHz version does not. The 433-MHz kit is different than the other versions in both software and hardware.
