This equipment is intended for use in a laboratory test environment only. It generates, uses, and can
radiate radio frequency energy and has not been tested for compliance with the limits of computing
devices pursuant to subpart J of part 15 of FCC rules, which are designed to provide reasonable
protection against radio frequency interference. Operation of this equipment in other environments may
cause interference with radio communications, in which case the user at his own expense will be required
to take whatever measures may be required to correct this interference.

1.1 MSP-EXP430F5438 Experimenter Board Introduction
The MSP-EXP430F5438 Experimenter Board is an evaluation board meant to evaluate the capabilities of
the MSP430F5438A family of microcontrollers. Built to complement the MSP430's high degree of
mixed-signal integration, the Experimenter Board showcases external peripherals such as a dot-matrix
LCD, two-axis accelerometer, microphone, audio output, a serial USB connection, and RF add-ons.
Delivered with an example software project to help firmware designers understand how to program the
new peripherals of the MSP430F5xx family of devices, there is no better way to learn how to use the
MSP430F5438A than with the MSP-EXP430F5438 Experimenter Board. This document details the
hardware, its use, and the example software.

Tools Requirements
1.3 Tools Requirements
1.3.1 Hardware
An MSP430 Flash Emulation Tool (MSP-FET430UIF) or equivalent programming tool is required to
download code and debug the MSP430F5438A. The JTAG programmer is connected to the
MSP-EXP430F5438 Experimenter Board via the JTAG header located in the top center of the board. The
MSP430F5438A utilizes the standard 4-wire JTAG connection. For more details on the installation and
usage of the Flash Emulation Tool, see the MSP430 Hardware Tools User's Guide (SLAU278). [3]
1.3.2 Software
Texas Instruments' Code Composer Studio (CCS) is an MSP430 integrated development environment
(IDE) designed specifically to develop applications and program MSP430 devices. CCS, CCS Core
Edition, and IAR Embedded Workbench can all be used to evaluate the example software for the
Experimenter Board. The compiler limitation of 4 KB prevents IAR KickStart from being able to be used for
the evaluation of the example software.
The example software, titled "User Experience," is available online as MSP-EXP430F5438(A) Example
Software (SLAC227). The User Experience application must be loaded onto the MSP430F5438A that
comes with the kit and is documented in Chapter 5. When compiled and run using an IDE, the APIs that
have been included in the example software can be used to develop unique applications with the
Experimenter Board. The APIs can serve as interfaces to the internal hardware modules of the
MSP430F5438A (for example, ADC12 or UCS) as well as external peripherals and components (for
example, buttons or an LCD). Chapter 5 describes the steps required to compile and run the example
software using Code Composer Studio.
