Getting Started With MSP-EXP430G2 LaunchPad
2.1
www.ti.com
Download the Required Software
There are different development software tools available for the MSP-EXP430G2 LaunchPad development
board. IAR Embedded Workbench KickStart and Code Composer Studio (CCS) are both available in a
free limited version. IAR Embedded Workbench allows 4kB of C-code compilation. CCS is limited to a
code size of 16kB. The software is available at www.ti.com/msp430 or the LaunchPad Wiki page
http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2). There are many other
compilers and integrated development environments (IDEs) for MSP430 including Rowley Crossworks and
MSPGCC available to use with the MSP-EXP430 LaunchPad. However, example projects have been
created using IAR Embedded Workbench KickStart and Code Composer Studio (CCS). For more
information on the supported software and the latest code examples visit the LaunchPad Wiki page.
2.2
Install the Software
Download one of the integrated development environments (IDEs). IAR KickStart and CCS offer the
required driver support to work with the MSP-EXP430 LaunchPad onboard emulation. Once installed, the
IDE should find the MSP-EXP430G2 LaunchPad as USB:HID debugging interface. Now all is set for
developing MSP430G2xx based application on the LaunchPad.
2.3
Install the Hardware
Connect the EXP430G2 LaunchPad socket board with the enclosed USB cable to a PC. The driver
installation starts automatically. If prompted for software, allow Windows to install the software
automatically. This is possible only if either IAR KickStart or Code Composer Studio is already installed
(see Section 2.2).

Getting Started With MSP-EXP430G2 LaunchPad
3.1
Getting Started
The first time the MSP-EXP430G2 LaunchPad Experimenter Board is used, a demo application
automatically starts as soon as the board is powered from the USB host. To start the demo, connect the
MSP-EXP430G2 LaunchPad with the included mini USB cable to a free USB port. The demo application
starts with an LED toggle to show the device is alive. More information about the Demo Application can be
found in Section 3.2.
3.2
Demo Application, Internal Temperature Measurement
The LaunchPad experimenter board includes a pre-programmed MSP430G2231 device already located in
the target socket. When LaunchPad is connected via USB, the demo starts with an LED toggle sequence.
The onboard emulation generates the supply voltage and all the signals necessary to start.
Pressing button P1.3 switches the application to a temperature measurement mode. A reference
temperature is taken at the beginning of this mode and the LEDs of the LaunchPad signal a rise or fall in
temperature by varying the brightness of the on-board red or green LED, respectively. The reference
temperature can also be re-calibrated with another button press on P1.3. The collected temperature data
is also communicated via back-channel UART through the USB emulation circuitry back to the PC. The
transmitted values representing the temperature measured with the MSP430G2231 internal temperature
sensor in Fahrenheit and can be displayed with any terminal application or the Temperature Sensor GUI
available on the MSP430 LaunchPad wiki page
http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2). The serial communication
port on the PC must configured with 2400bps, one stop bit, and no flow control to display the values
correctly.
The demo application uses the on-chip peripherals of the MSP430G2231 device such as the 10-bit ADC,
which samples the internal temperature sensor, and 16-bit timers, which drive the PWM to vary brightness
of the LEDs and enable software UART for communication with the PC. The source code for this
pre-loaded demo application is available for download in the Projects section of the MSP430 LaunchPad
wiki page. Further information on the Temperature Sensor application and other examples and
applications can be found on the MSP430 LaunchPad wiki page as well.

4.1
Developing an Application
The integrated development environments (IDEs) shown in Section 2 offer support for the whole
MSP430G2xx Value Line. The MSP-EXP430G2 LaunchPad needs only a connection to the USB of the
Host PC—there is no external hardware required. The power supply and the Spy-Bi-Wire JTAG signals
TEST and RST must be connected with jumper J3 to allow the onboard emulation connection to the
device, as shown in Section 5. Now the favored device can be plugged into the DIP target socket of the
LaunchPad experimenter board (see Figure 2). Both PDIP14 and PDIP20 devices of the MSP430G2xx
Value Line and the MSP430F20xx family can be inserted into the DIP socket aligned to pin 1. A complete
list of supported devices can be found in Section 4.7.
Figure 2. Insert Device Into Target Socket
The following example for Code Composer Studio v4 shows how to download and debug the demo
application described in Section 3.2.
4.2
Program and Debug the Temperature Measurement Demo Application
The source code of the demo application can be downloaded from the MSP430 LaunchPad wiki page.
Download the project folder and unpack it to a location of your choice. For this demo, Code Composer
Studio v4 or newer must be installed.
The demo application can be loaded to the CCS workspaces by clicking File→Import. Select the location
of the extracted project files and import Existing projects into Workspace. Now the
MSP-EXP430G2-Launchpad project appears inside the CCS workspace. The project must be marked as
the active project to start programming and debugging the device.
Connect the LaunchPad with an inserted MSP430G2231 device to the host PC and click the Debug button
on the CCS Toolbar. The MSP-EXP430G2 LaunchPad is initialized and the download of the compiled
demo application starts. The CCS view switches to a debugging interface once the download is completed
and the application is ready to start. Figure 3 shows Code Composer Studio v4 with the MSP-EXP430G2
LaunchPad demo application in debug view.

Disconnect Emulator From Target With Jumper J3
The connection between the MSP-EXP430G2 emulator and the attached target device can be opened
with the jumper array J3. This can be useful to access an attached eZ430 target board by disconnecting
the Spi-Bi-Wire JTAG lines RST and TEST or if the JTAG lines are used for other application purposes.
The jumper array can also be used to measure the power consumption of the LaunchPad application. For
this intention, all connections except VCC must be opened, and a multi meter can used on VCC to
measure the power consumption of the MSP-EXP430G2 target device and its peripherals. The jumper 5
VCC also must be opened if the LaunchPad board is powered with an external power supply over J6.
Table 1 shows the jumpers in between the MSP-EXP430G2 emulator and the target device.

watch module, or the eZ430-F2012T/F2013T. To connect one of the ez430 targets, connector J4 must be
populated with a 0.050-in (1.27-mm) pitch male header, as shown in Figure 4, to connect the target
boards.

Figure 4. MSP-EXP430G2 LaunchPad With Attached eZ430-RF2500 Target Board
To program the attached target without interfering with the LaunchPad socket board, jumper connections
TEST and RST of J3 must be open. The interface to the eZ430 target board is always connected to the
MSP-EXP430G2 emulator, so the programming and debugging of a connected LaunchPad target device
is possible only if the eZ430 target is not connected on the same time. The application UART, on the other
hand, is connected directly to the LaunchPad target device, and jumper J3 can be closed to monitor the
transmission from the LaunchPad target to the attached eZ430. This way both possible connections, from
the device to the PC and from the device to the eZ430, can be established without changing the direction
of the UART pins.

Connecting a Crystal Oscillator
The MSP-EXP430G2 LaunchPad offers a footprint for a variety of crystal oscillators. The XIN and XOUT
signals of the LFXT1 oscillator can support low-frequency oscillators like a watch crystals of 32768 Hz or a
standard crystal with a range defined in the associated datasheet. The signal lines XIN and XOUT can
also be used as multipurpose I/Os or as a digital frequency input. More information on the possibilities of
the low-frequency oscillator and the possible crystal selection can be found in the MSP430x2xx Family
User's Guide (SLAU144) or the device-specific data sheet.
The oscillator signals are connected to connecter J2 to use the signals on an attached application board.
In case of signal distortion of the oscillator signals that leads to a fault indication at the basic clock module,
resistors R29 and R28 can be used to disconnect the pin header J2 from the oscillating lines.

Connecting a Satellite Board
The LaunchPad is the perfect experimenter board to start hardware development with the MSP430G2xx
Value Line. Connectors J1/J2 and the power supply at J6 are aligned in a 0.1-in (2.54-mm) grid to allow
an easy and cheap development of a breadboard extension module. These satellite boards can access all
the signals of the LaunchPad target device. So the satellites can hold their own device and use the
LaunchPad as a pure programming interface or work with the device plugged into the LaunchPad socket.
The alignment of the connectors and the pin out can be found in Section 5. The MSP-EXP430G2
LaunchPad kit includes four 10-pin PCB connectors (two male and two female) to get started with the first
extension board right away.

Suggested Reading
The primary sources of MSP430 information are the device-specific data sheets and user's guides. The
most up-to-date versions of those documents can be found at the Texas Instruments MSP430 page or the
MSP430 LaunchPad wiki.
www.ti.com/msp430, http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2)
To get an inside view of the supporting IDEs like CCS and IAR, download the latest version from the web
pages above and read the included user's guides and documentation inside the installation folder.
Documents describing the IAR tools (Workbench/C-SPY, the assembler, the C compiler, the linker, and
the library) are located in common\doc and 430\doc. All necessary CCS documents can be found inside
the msp430\doc inside the CCS installation path. The FET user's guide also includes detailed information
on how to set up a project for the MSP430 using IAR or CCS, and it is included in most of the IDE
releases and on the TI MSP430 side.

Requently Asked Questions (FAQ)
1. Does the MSP-EXP430G2 support fuse blow?
The MSP-EXP430G2 LaunchPad experimenter board onboard debugging interface lacks the JTAG
security fuse-blow capability. To ensure firmware security on devices going to production, the USB
Flash Emulation Tool or the Gang Production Programmer, which support the fuse-blow feature, are
recommended.
2. Can other programming tools like the MSP-FET430UIF interface the MSP-EXP430G2 LaunchPad
socket device?
The LaunchPad experimenter board works with any programming tool supporting the 2-wire
Spy-Bi-Wire interface. Both the MSP430 USB FET (MSP-FET430UIF) and the Gang Programmer
(MSP-GANG430) support these devices, but the connection must be made directly to the dedicated
Spy-Bi-Wire ports. See MSP-FET430 Flash Emulation Tool User's Guide (SLAU138) for details on
using MSP430 USB FET and the Gang Programmer for a 2-wire Spy-Bi-Wire interface. Don't try to
connect the standard JTAG connector to the MSP-EXP430G2 pinheads, as this could result in damage
to the attached hardware.
3. What versions of IAR Embedded Workbench and Code Composer Studio are supported?
The MSP-EXP430 LaunchPad hardware is supported by IAR Embedded Workbench KickStart Version
6.00 and Code Composer Studio v4 or higher. To download the software and for more information on
the supported software visit the LaunchPad Wiki page.
http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2)
4. What are the part numbers for the connectors between the LaunchPad emulator board and the other
eZ430 target boards?
Header: Mill-Max 850-10-006-20-001000
Socket: Mill-Max 851-93-006-20-001000
5. I am not able to select the MSP430 Application UART and cannot receive data.
Ensure that the Application UART driver is correctly installed. This is done by installing either IAR
Embedded Workbench or Code Composer Studio v4.
To determine if the driver is correctly installed:
a. Plug in the MSP-EXP430G2 LaunchPad with the included Mini USB cable.
b. Right click My Computer and select Properties.
c. Select the Hardware tab and click on Device Manager.
d. Under Ports (COM & LPT) should be an entry for "MSP430 Application UART (COM xx)".
If the entry is there, but no characters are received, reconnect the LaunchPad to the PC and restart the
application to reload the drivers. If the Application UART is not listed, install the driver by following the
instructions in Section 2.2.
6. The device is not answering to any communication, JTAG or UART.
If you are experiencing difficulties in communicating to the attached MSP430 target device, even
though all the communication drivers for the MSP-EXP430G2 are loaded correctly, the emulator is
probably set to a wrong communication state. This can be fixed by reconnecting the LaunchPad
Experimenter Board and restarting the communicating application.
