1.1 Overview
The eZ430-Chronos software development tool is a highly integrated, wearable, wireless development
system that is based on the CC430F6137. It may be used as a reference platform for watch systems, a
personal display for personal area networks, or as a wireless sensor node for remote data collection.
Based on the CC430F6137 sub-1-GHz RF SoC, the eZ430-Chronos is a complete development system
featuring a 96-segment LCD display, an integrated pressure sensor, and a three-axis accelerometer for
motion sensitive control. The integrated wireless interface allows the eZ430-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 MSP430F5509 +
CC1101 (part of the new eZ430-Chronos kit with white PCBs) or CC1111 (part of the initial eZ430Chronos kit with black PCBs) wireless interface to a PC.
The eZ430-Chronos wrist module may be disassembled to be programmed with custom applications and
includes an eZ430 USB programming interface.

measurement are made in intervals of 1 second.
The implementation of the altitude algorithm is done according to the VTI's application report AN33 without
any additional low-power optimizations. Therefore, the altimeter is active only in altimeter mode. In
addition, a timeout deactivates the measurements after 60 minutes. Altitudes above sea level are
indicated with a small arrow pointing up in the upper LCD line, left of the altitude. Altitudes below sea level
are indicated with a small arrow pointing down.
The altimeter algorithm is based on the air pressure and the ambient temperature. Therefore, changes in
air pressure affect the altitude accuracy. For precise measurements, the altimeter must be calibrated
manually for weather changes.
eZ430-Chronos Demo Software
NOTE: For most accurate altitude measurement, the wrist module must be fully exposed to the
ambient temperature (that is, the wrist module should not be worn directly on the arm),
because temperature is part of the altitude measurement (see Section 3.2.1.3).
Secondary function: Re-activate altimeter after timeout
Set function: Altitude calibration
1. Hold * for three seconds until the altitude starts to flash.
2. Set the altitude by pushing the UP or DOWN button.

3.6.2 eZ430-Chronos Software Flow
The Chronos module software is structured according to the menu items. The source for each menu item
is stored in a separate source file (for example, "temperate.c" for the temperature menu and its functions).
Details can be found in the flow chart in Figure 3-12. The data logger application works in a very similar
way and, therefore, is not described separately.
Each menu item has at least the following functions:
• UP or DOWN button pushed
• * or # button is pressed for more than three seconds
The source code file "menu.c" contains two linked lists with menu items, one for the upper LCD line
(Line1), one for the lower LCD line (Line2). Each list entry contains the following pointers:
• Pointer to next menu item
• UP or DOWN button is pressed
• * or # button is pressed for more than three seconds
To support the various RF frequencies and compiler licenses, the following configurations are available:
RF Frequencies
• 915 MHz (USA)
• 868 MHz (Europe)
• 433 MHz (Other regions)
IDE Versions (CCS, IAR)
• Unrestricted IDE versions
• Free IDE versions (CCS Core Edition, IAR KickStart). To allow recompilation of the source code, parts
of the source code files have been embedded in libraries; for example, the SimpliciTI stack and most of
the hardware drivers.
Figure 3-12 shows the basic software flow of the demo application.

After a power-up reset, the hardware is initialized, the display memory is cleared and the radio is set to
sleep mode. The main loop waits for wake-up events, which can be either a scheduled event such as a
clock interrupt, or a button event.
Button events lead to the execution of either mx_functions or sx_functions.
If the LCD is updated with new data, the modules set a display flag, and LCD Line1, Line2, or both are
updated by calling the menu-specific display functions. Display updates have been reduced as much as
possible; for example, when the time changes from 10:22 to 10:23, only the last digit is updated.

3.6.3 eZ430-Chronos Wireless Update Feature
The wireless update feature allows to perform a firmware update of the eZ430-Chronos wrist module
wirelessly, that is the Chronos module does not need to be opened. The wireless update software should
be seen as an application and not as an universal BSL. It can only be invoked by the main application,
which needs to be created in a certain way (see Section 3.6.3.2). In addition it may must be modified to
comply local RF regulatory. The current consumption during the update process may be significant.
Considering the small battery capacity, the update software is intended to be used only occasionally.
NOTE: References in the software projects and the menu items of the Chronos module refer to it as
"RF BSL" and "WBSL" for simplicity reasons.
Whenever the wireless update is activated on the Chronos module, it returns to the main
application with a reset, wether or not an update was performed. Time, data, alarm, and
other RAM-based data are lost.
3.6.3.1 Overview and Components of the Wireless Update Feature
As described in Section 3.6.3, the wireless update feature allows wireless updates of the eZ430-Chronos
firmware. One of the requirements for the wireless update implementation is to use as little flash memory
as possible. Therefore, a lightweight radio protocol was developed, which resides in the BSL flash area of
the CC430. The software that handles the LCD progress information and the flash memory programming
is downloaded over the air and executed in RAM. Components of the wireless update software include:
• Radio protocol in BSL memory area of the CC430 (eZ430-Chronos wrist module)
• The "RAM-based update software" contains LCD and flash write routines (transferred from PC to RAM
of the wrist module)
• Radio protocol stack of the wireless update on RF access point (CC1111 or MSP430F5509 + CC1101)
• PC application supporting the update functionality
The update procedure works as follows:
1. Wireless update functionality is activated in the PC application, after a valid flash image is selected
2. RF access point is ready and awaits a request from a Chronos module
3. Wireless update is activated on the Chronos module
4. Chronos module downloads LCD and flash write routines (RAM-based update software) from the PC
into the RAM of the CC430. The Chronos module displays "rAN" (=RAM).
5. Chronos module executes the RAM-based update software. This starts the actual code (flash image)
download process. The LCD shows the progress.
6. A reset starts the new application on the Chronos module when the update is finished.
The FAQ in Appendix A also list common questions on the wireless update feature.
eZ430-Chronos Software Projects
3.6.3.2 Detailed Description of the Wireless Update Feature
To invoke the wireless update procedure, the main application must call the start of the wireless update
software, which is located at address 0x1000. Therefore, the demo and data logger projects contain an
extra menu item called "rFbSL". When activated, it determines if the battery level of the Chronos module is
sufficient to start a wireless update and then calls address 0x1000. At this time, the user application is no
longer running.
NOTE: Whenever the wireless update is activated on the Chronos module, it returns to the main
application with a reset, whether or not an update was performed. Time, data, alarm, and
other RAM-based data is lost.

eZ430-Chronos Software Projects
After invoking the wireless update (rFbSL), the Chronos module tries to link to a listening RF access point
and start the update procedure. If the link is successful, the Chronos module downloads the RAM-based
update software into the RAM of the CC430. Once finished, this software then tries to link again with the
RF access point to download the actual update image. If this link is successful, a mass flash erase is
performed, which erases all the main memory flash (0x8000 to 0xFFFF). The Chronos module then starts
to receive all of the data packets and writes them to flash, checking if each word was written successfully.
If the link is not successful, the Chronos module generates a reset to restart the user application. During
the download of the update image, a percentage indicator appears on the Chronos module. When
download is complete, "dOnE" is shown on the LCD, and a reset is generated to start the new user
application that has just been written to flash.
A detailed flow of the update software on the Chronos module and the USB access point can be found in
Figure 3-13 and Figure 3-14.

3.6.3.3 Error Handling
The wireless update software is designed to be fail safe. The radio protocol contains limited error handling
due to its small footprint, but the update software provides recovery if the update process fails. Upon
communication failures, the Chronos module is put in low-power mode (LPM4) and the LCD is turned off.
The update process can be restarted by pushing the DOWN button after the update process is restarted
on the PC.

3.6.3.4.2 eZ430-Chronos Wrist Module Update
The update of the eZ430-Chronos wrist module needs to be done in two stages. First, the wireless update
software needs to be written to the BSL area of the flash memory of the CC430. Afterwards, the main
application must be loaded onto the wrist module. The easiest and fasted way is using BM innovations'
Firmware Update Tool. It writes the wireless update software into the BSL memory of the wrist module
and programs the corresponding demo firmware according to the latest eZ430-Chronos software release
(recommended).
Alternatively, the wireless update software may be loaded onto the wrist module using the included IAR
Embedded Workbench (free KickStart version is sufficient). Moreover, the .txt image may be written to the
device by using 3rd party tools such as the free FET-Pro430 Lite software from Elprotronic.

3.6.5 eZ430-Chronos GUI Sources
Full sources of the eZ430-Chronos Control Center and eZ430-Chronos Data Logger are available in the
eZ430-Chronos software packages for Windows SLAC341 and Linux SLAC388. The sources are copied
to the PC during the software installation. The graphical user interfaces are based on TCL/Tk.
www.ti.com
3.6.5.1 eZ430-Chronos GUI for Windows
The eZ430-Chronos PC software consists of a TCL/Tk executable and a DLL, which handles the
communication with the RF access Point. Download TCL/Tk for Windows for free from
http://www.activestate.com/activetcl. Once TCL/Tk was installed on the computer, a double-click on a TCL
script (*.tcl) starts the interpreter and executes the script. Alternatively, start the TCL interpreter wish.exe
and execute the script with the "source" command. If the script filename contains blanks, put it into quotes.
The sources files are located in C:\Program Files\Texas Instruments\eZ430-Chronos\Control Center\GUI
Sources
3.6.5.1.1 TCL/TK Handling
A wrapping tool is needed to compile all TCL/Tk components into standalone applications. The freeware
tool Freewrap http://freewrap.sourceforge.net may be used for that purpose.
1. Open Command Prompt
2. Navigate to the Freewrap directory; for example, C:\Tcl\freewrap
3. Start Freewrap with the complete path to the TCL script to be wrapped; for example, freewrap.exe
C:\Program Files\Texas Instruments\eZ430-Chronos\Control Center\eZ430-Chronos Control
Center\eZ430-Chronos CC 1_2.tcl
A standalone application, which only requires the corresponding Windows DLL is generated. It can be
used on every PC, TCL/Tk must not be installed.

3.6.5.1.2 Control Center DLL
The sources for the DLL are available in the eZ430-Chronos Windows package and can be found in
C:\Program Files\Texas Instruments\eZ430-Chronos\Control Center\GUI Sources\DLL.
The eZ430-Chronos Windows DLL has been developed using Microsoft Visual C++ 2008 Express Edition.
In order to rebuild the DLL file the Microsoft Visual Studio must be installed, since the registry enumeration
code uses MFC functions. If Microsoft Visual Studio is not present, it is still possible to rebuild the DLL, but
the "enumser" source code part needs to be removed from the project. Therefore, the BM_GetCOM()
function won’t work anymore.
The DLL has two interface sections, one that exports standard C functions, and a second one exporting
TCL-compliant functions. These TCL-compliant functions are used by the graphical user interface. Hence,
when compiling the DLL, TCL needs to be present in the default directory (C:\Tcl); otherwise, the
reference to the TCL libraries (tcl85.lib, tclstub85.lib) is invalid. If the DLL is compiled without the TCL
interface, the respective source code file and the references to the TCL libraries must be deleted.
COM Port Management
1. Opening the COM port
Prior to any communication, the COM port where the RF access point is connected must be opened.
The hardware is powered up immediately after the unit is connected. Some parts of the hardware
require a startup time of several hundred milliseconds. As a result, any access to the hardware should
not be done within one second after connecting the device.
NOTE: To address COM ports higher than COM9 in Windows, precede the "COMxx" string with the
sequence "\\.\".
eZ430-Chronos Software Projects
The COM port is opened with the following function:
bool BM_OpenCOM( char * strPortName,
DWORD dwBaudrate = 115200,
WORD wTimeout = 30,
bool bRTS = false,
bool bDTR = false);
Parameters
strPortName
Name of the COM port (for example, "\\.\COM11").
wTimeout
Time in milliseconds a reply to a command is expected; default value is 30 ms, should not be
changed
dwBaudrate
Baudrate for the serial interface; default is 115200 Baud, should not be changed
bRTS
State of RTS line during normal operation; default is false (=GND), should not be changed
bDTR
State of DTR line during normal operation; default is false (=GND), should not be changed
Return Value
Returns true if COM port could be opened, otherwise returns false.
2. Closing the COM port
A successfully opened COM port must be closed when quitting the application to release all allocated
memory and the port itself.
The COM port is closed with the following function:
void BM_CloseCOM(void);

4.3 Functional Description of the eZ430-Chronos RF Access Point
The RF access point allows wireless communication with the eZ430-Chronos directly from the PC to
download data, sync information, or control programs running on the PC (see Figure 4-10).
4.3.1 Access Point With Black PCB
This access point is based on the CC1111F32 controller, which features an integrated USB controller in
addition to a <1-GHz radio.
Figure 4-10. eZ430-Chronos RF Access Point
NOTE: The access point is this kit comes in a small production-ready design. Therefore, it does not
include a JTAG connector. However, the bottom side provides pads that allow soldering
cables to connect the CC1111 to the CC Debugger. TI also offers the professional
CC1111EMK868-915 development kit including connectors and a push button.
www.ti.com
To program the RF access point, a debug interface connector cable must be soldered to the CC1111
access point as shown in Figure 4-11.

4.3.2 Access Point With White PCB
This access point consists of an MSP430F5509 microcontroller connected to a <1-GHz transceiver
(CC1101) (see Figure 4-12).
Figure 4-12. Access Point With White PCB
As shown in Figure 3-15, the RF access point can be reprogrammed by connecting the eZ430 USB
emulator to the access point. First of all, solder the 4-pin debugger connector (provided with the kit) onto
the access point.

Functional Description of the eZ430-Chronos Debug Interface
4.4 Functional Description of the eZ430-Chronos Debug Interface
The eZ430-Chronos kit includes an USB emulator that provides full programming and debugging features
using its Spy-Bi-Wire (2-wire) interface. It features a back channel MSP430 application UART that may be
used independently of a debug session.
NOTE: The eZ430 USB emulator with white or black PCB are identical from a hardware perspective.
Despite the fact that the Chronos module is equipped with a 6-pin connector, there is no
UART connection from the Chronos module to the emulator as all pins of the CC430 are
already used for other purposes.
Supported devices:
• CC430F51xx
• CC430F61xx
• MSP430F20xx
• MSP430F21x2
• MSP430F22xx
• MSP430F41x2
• MSP430F54xx
• MSP430F54xxA
• MSP430F55xx
Connector J1 on the emulator (starting on top with pin 1) (see Figure 4-14).
• UART TX (from emulator to target)
• 3.6-V supply for target
• TEST/SBWTCK
• RST/SBWTDIO
• GND
• UART RX (from target to emulator)

4.4.1 MSP430 Application UART
The eZ430-Chronos emulator includes a back channel MSP430 Application UART that may be used
independently of a debug session. This allows the user to transfer serial data to a terminal window at a
fixed rate of 9600 bps with no flow control. Check the Device Manager for COM port assignment of the
MSP430 Application UART (for more details, see Section B.2).
