1.1 Introduction

The MSP-EXP430FR6989 LaunchPad Development Kit is an easy-to-use Evaluation Module (EVM) for

the MSP40FR6989 microcontroller (MCU). It contains everything needed to start developing on the ultra-

low-power MSP430FRx FRAM microcontroller 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 as well as a Liquid Crystal Display (LCD) display which showcases

the integrated driver that can drive up to 320 segments. It also offers direct access to the Extended Scan

Interface, which is a dual analog front-end (AFE) created for low-power rotation detection. The

MSP430FR6989 device features ultra-low power consumption, 128KB of embedded ferroelectric random

access memory (FRAM), a nonvolatile memory known for its ultra-low power, high endurance, and high-

speed write access.

Rapid prototyping is simplified by the 40-pin BoosterPack™ Plug-in Module headers, which support a wide

range of available BoosterPack modules. 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.

The out-of-box provided with the MSP-EXP430FR6989 LaunchPad features the on-board segmented

display and offers two operating modes. Stopwatch Mode can run a timer for up to 24 hours, or

alternatively operate split time, where the display can be frozen and the stopwatch continues running in

the background. The second mode provides a simple thermometer application using the on-chip

temperature sensor. The temperature is displayed on the LCD and can be shown in degrees Fahrenheit or

Celsius.

Free software development tools are also available, such as TI's Eclipse-based Code Composer Studio

(CCS) and IAR Embedded Workbench. Both of these IDEs support EnergyTrace++™ technology for real-

time power profiling and debugging when paired with the MSP430FR6989 LaunchPad. More information

about the LaunchPad, the supported BoosterPack modules and available resources can be found at TI's

LaunchPad portal.

1.4 First Steps: Out-of-Box Experience

An easy way to get familiar with the EVM is by using its preprogrammed out-of-box code. This code

demonstrates some key features from a user level.

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. TI recommends installing these driver by installing an

IDE such as TI's CCS or IAR EW430. Drivers are also available at http://www.ti.com/MSPdrivers.

1.4.2 Running the Out-of-Box Demo

When connected to your 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. See Section 3 for

detailed explanations of each mode.

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 4 for available IDEs and

where to download them.

The quickest way to get started using the LaunchPad is to use TI's Cloud Development Tools,

http://dev.ti.com. The cloud-based Resource Explorer provides access to all of the examples and

resources in MSPWare. Code Composer Studio Cloud is a simple Cloud-based IDE that enables

developing and running applications on the LaunchPad.

The out-of-box source code and more code examples are provided for download at

http://www.ti.com/tool/msp-exp430fr6989. Code is licensed under BSD, and TI encourages reuse and

modifications to fit specific needs.

Section 3 describes all functions in detail and provides a 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-EXP430FR6989 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-EXP430FR6989 LaunchPad features full EnergyTrace++ technology. The EnergyTrace

functionality varies across the MSP portfolio, shown in Table 1.

Table 1. EnergyTrace Technology

Features EnergyTrace™ Technology EnergyTrace++™ Technology

Current Monitoring Yes Yes

CPU State No Yes

Peripheral and System State No Yes

Devices Supported All MSP430 MCUs MSP430FR59xx and FR69xx 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.

In Figure 5, the dotted line through J101 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 MSP-EXP430FR6989

Hardware Design Files. The software and more information about the debugger can be found on the eZ-

FET wiki.

2.2.3 Emulator Connection: Isolation Jumper Block

The isolation jumper block at jumper J101 connects or disconnects signals that cross from the eZ-FET

domain into the MSP430FR6989 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.

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 very 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.

Figure 7 shows the pathway of the backchannel UART. The backchannel UART is the UART on

eUSCI_A1. This UART channel is separate from the UART on the 20-pin BoosterPack connector

(eUSCI_A0).

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.
