1 Getting Started
1.1 Introduction
The MSP-EXP430FR4133 LaunchPad™ Development Kit is an easy-to-use Evaluation Module (EVM) for
the MSP430FR4133 microcontroller (see Figure 1). It contains everything needed to start developing on
the MSP430™ ultra-low-power (ULP) FRAM-based microcontroller (MCU) platform, including on-board
emulation for programming, debugging, and energy measurements. The board features on-board buttons
and LEDs for quick integration of a simple user interface and a liquid crystal display (LCD) that showcases
the integrated driver with flexible software-configurable pins. The MSP430FR4133 device features
embedded FRAM (ferroelectric random access memory), a nonvolatile memory known for its ultra-low
power, high endurance, and high-speed write access.
Rapid prototyping is simplified by the 20-pin BoosterPack™ Plug-in Module headers, which support a wide
range of available BoosterPacks. You can quickly add features like wireless connectivity, graphical
displays, environmental sensing, and much more. Design your own BoosterPack or choose among many
already available from TI and third-party developers.
Free software development tools are also available, including TI's Eclipse-based Code Composer
Studio™ (CCSTUDIO) and IAR Embedded Workbench®IAR-KICKSTART. Both of these integrated
development environments (IDEs) support EnergyTrace™ technology when paired with the
MSP430FR4133 LaunchPad. More information about the LaunchPad, the supported BoosterPacks, and
available resources can be found at TI's LaunchPad portal.

1.4.1 Connecting to the Computer
Connect the LaunchPad using the included USB cable to a computer. A green power LED should
illuminate. For proper operation, drivers are needed. It is recommended to get drivers by installing an IDE
such as TI's CCS or IAR EW430. Drivers are also available at www.ti.com/MSPdrivers.
1.4.2 Running the Out-of-Box Demo
When connected to the computer, the LaunchPad powers up and displays a greeting message on the
LCD. Press and hold the S1 and S2 buttons simultaneously to select a new mode. A more detailed
explanation of each mode can be found in Section 3.4.
1.4.2.1 Stopwatch Mode
This mode provides a simple stopwatch application. It supports split time, where the display freezes while
the stopwatch continues running in the background.
Timer Stopped:
S1: Start time
S2: Reset time
Timer Running:
S1: Stop time
S2: Split time (lap time)
1.4.2.2 Temperature Mode
This mode provides a simple thermometer application. Using the on-chip temperature sensor, the
temperature is displayed on the LCD.
S1: Pause current temperature
S2: Toggle temperature between °F and °C
1.5 Next Steps: Looking Into the Provided Code
After the EVM features have been explored, the fun can begin. It's time to open an integrated
development environment and start editing the code examples. Refer to Section 3.3 for more information
on IDEs and where to download them.
The out-of-box source code and more code examples are provided for download at
http://www.ti.com/tool/msp-exp430fr4133. Code is licensed under BSD, and TI encourages reuse and
modifications to fit specific needs.
Section 3 describes all of the functions in detail and describes the project structure to help familiarize you
with the code.
With the onboard eZ-FET emulator debugging and downloading new code is simple. A USB connection
between the EVM and a PC through the provided USB cable is all that is needed.

2.2.2 eZ-FET Onboard Emulator With EnergyTrace™ Technology
To keep development easy and cost effective, TI's LaunchPad Development Kits integrate an onboard
emulator, which eliminates the need for expensive programmers. The MSP-EXP430FR4133 has the eZ-
FET emulator (see Figure 5), which is a simple and low-cost debugger that supports all MSP430 device
derivatives.
Figure 5. eZ-FET Emulator
The MSP-EXP430FR4133 LaunchPad features EnergyTrace technology but does not have support for
EnergyTrace++™ technology. The EnergyTrace functionality varies across the MSP portfolio (see
Table 1).

Devices Supported All MSP430 MCUs MSP430FR59xx and
MSP430FR69xx MCUs
Development Tool Required MSP-FET or eZ-FET MSP-FET or eZ-FET
The eZ-FET also provides a "backchannel" UART-over-USB connection with the host, which can be very
useful during debugging and for easy communication with a PC. The provided UART supports hardware
flow control (RTS and CTS), although by default these signals are not connected to the target.
The dotted line through J101 shown in Figure 5 divides the eZ-FET emulator from the target area. The
signals that cross this line can be disconnected by jumpers on J101, the isolation jumper block. More
details on the isolation jumper block are in Section 2.2.3.
The eZ-FET hardware can be found in the schematics in Section 6 and in the accompanying MSP-
EXP430FR4133 Hardware Design Files. The software and more information about the debugger can be
found on the eZ-FET lite wiki.

2.2.3 Emulator Connection: Isolation Jumper Block
The isolation jumper block at jumper J101 allows the user to connect or disconnect signals that cross from
the eZ-FET domain into the MSP430FR4133 target domain. This includes eZ-FET Spy-Bi-Wire signals,
application UART signals, and 3.3-V and 5-V power (see Table 2 and Figure 6).
Reasons to open these connections:
• To remove any and all influence from the eZ-FET emulator for high accuracy target power
measurements
• To control 3-V and 5-V power flow between the eZ-FET and target domains
• To expose the target MCU pins for other use than onboard debugging and application UART
communication
• To expose the programming and UART interface of the eZ-FET so that it can be used for devices other
than the onboard MCU.

of the signal.

2.2.4 Application (or "Backchannel") UART
The backchannel UART allows communication with the USB host that is not part of the target application's
main functionality. This is useful during development and also provides a communication channel to the
PC host side. This can be used to create graphical user interfaces (GUIs) and other programs on the PC
that communicate with the LaunchPad.
The pathway of the backchannel UART is shown in Figure 6. The backchannel UART is the UART on
eUSCI_A0. Because of USCI limitations, this UART channel is shared with the UART on the 20-pin
BoosterPack connector (eUSCI_A0). This UART channel is also shared with the red LED on P1.0. This is
a lot of sharing, but all 64 pins of the device are used and this was done out of necessity. The P1.0 pin
serves more functions than any other.
On the host side, a virtual COM port for the application backchannel UART is generated when the
LaunchPad enumerates on the host. You can use any PC application that interfaces with COM ports,
including terminal applications like Hyperterminal or Docklight, to open this port and communicate with the
target application. You need to identify the COM port for the backchannel. On Windows PCs, Device
Manager can assist (see Figure 7).
