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.

1.2 Key Features

• MSP430 ultra-low-power FRAM technology based MSP430FR4133 16-bit MCU

• 20-pin LaunchPad standard that leverages the BoosterPack ecosystem

• eZ-FET, an open-source onboard debugger that features EnergyTrace technology

• On-board segmented LCD

• Two buttons and two LEDs for user interaction

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.

RTS >> Backchannel UART: Ready-To-Send, for hardware flow control. The target can use this to indicate whether it

is ready to receive data from the host PC. The arrows indicate the direction of the signal.

CTS << Backchannel UART: Clear-To-Send, for hardware flow control. The host PC (through the emulator) uses this

to indicate whether it is ready to receive data. The arrows indicate the direction of the signal.

RXD << Backchannel UART: The target FR4133 receives data through this signal. The arrows indicate the direction

of the signal.

TXD >> Backchannel UART: The target FR4133 sends data through this signal. The arrows indicate the direction of

the signal.

SBW RST Spy-Bi-Wire emulation: SBWTDIO data signal. This pin also functions as the RST signal (active low).

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).
