User's Guide SLAU318C – July 2010 – Revised August 2012 MSP-EXP430G2 LaunchPad Experimenter Board 1 MSP-EXP430G2 LaunchPad Overview 1.1 Overview The MSP-EXP430G2 low-cost experimenter board called LaunchPad is a complete development solution for the Texas Instruments MSP430G2xx Value Line series. The integrated USB-based emulator offers all the hardware and software necessary to develop applications for all MSP430G2xx series devices.
MSP-EXP430G2 LaunchPad Overview www.ti.com Figure 1. MSP-EXP430G2 LaunchPad Overview For latest information on the MSP-EXP430G2 LaunchPad and all the necessary files, visit the MSP430 LaunchPad Wiki page http://processors.wiki.ti.com/index.php/MSP430_LaunchPad_(MSP-EXP430G2). There you can find software examples, more details on the supported software, and where to order the MSP-EXP430G2 LaunchPad. 1.
Installation www.ti.com 1.3 Revisions The first production revision of the LaunchPad in 2010 was 1.3. In 2012 the LaunchPad board revision changed from 1.4 to 1.5 to align with the new release of Value Line devices. The differences in the schematic and the kit contents are: • Layout and Schematic: – Voltage feedback in the emulator changed to increase startup stability (Rev 1.3 to Rev 1.
Getting Started With MSP-EXP430G2 LaunchPad 3 Getting Started With MSP-EXP430G2 LaunchPad 3.1 Getting Started www.ti.com 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 active.

Code Composer Studio™ v4 in Debugging Mode 4.3 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.
Develop an Application With the MSP-EXP430G2 LaunchPad www.ti.com 4.4 Program Connected eZ430 Target Boards The MSP-EXP430G2 LaunchPad can program the eZ430-RF2500T target boards, the eZ430-Chronos 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. Figure 4.
Develop an Application With the MSP-EXP430G2 LaunchPad 4.6 www.ti.com Connecting a Satellite Board The LaunchPad is the perfect experimenter board to start hardware development with the MSP430G2xx Value Line. Connectors J1 and J2 and the power supply at J6 are aligned in a 0.1-in (2.54-mm) grid to allow an easy and inexpensive development of a breadboard extension module. These satellite boards can access all the signals of the LaunchPad target device.
