1 Getting Started

1.1 Introduction

The MSP-EXP430FR5994 LaunchPad development kit is an easy-to-use evaluation module (EVM) for the

MSP430FR5994 microcontroller (MCU). The LaunchPad development kit contains everything needed to

start developing on the ultra-low-power MSP430FRx FRAM microcontroller platform, including onboard

debug probe for programming, debugging and energy measurements. The board features onboard buttons

and LEDs for quick integration of a simple user interface, a microSD card port to interface with microSD

cards, and a super capacitor (super cap) to enable stand-alone applications without an external power

supply.

The MSP430FR5994 MCU features 256KB of embedded FRAM (Ferroelectric Random Access Memory),

a nonvolatile memory known for its ultra-low power, high endurance, and high speed write access. The

device also features 8 KB of SRAM, supports CPU speeds of up to 16 MHz and has integrated

peripherals for communication, ADC, timers, AES encryption, low-energy accelerator (LEA) (a new

hardware module for the FRAM family that is designed for fast, efficient, and low-power vector math), and

more–plenty to get you started in your development.

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

range of available BoosterPack modules. Quickly add features like wireless connectivity, graphical

displays, environmental sensing, and much more. Design your own BoosterPack plug-in module or

choose among many already available from TI and third-party developers.

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

Studio™ IDE (CCS) and the IAR Embedded Workbench®for MSP430™ IDE (EW430). Both of these IDEs

support EnergyTrace++™ technology for real-time power profiling and debugging when paired with the

MSP430FR5994 LaunchPad kit.

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. It demonstrates

some key features from a user level.

1.4.1 Connecting to the Computer

Connect the LaunchPad development kit using the included USB cable to a computer. A green power LED

should illuminate. For proper operation, drivers are needed. TI recommends installing the drivers by

installing an IDE such as TI CCS or IAR EW430. Drivers are also available at ti.com/MSPdrivers.

1.4.2 Running the Out-of-Box Demo

When connected to the computer, the LaunchPad development kit powers up. Press and hold the S1 and

S2 buttons simultaneously to select a new mode. See Section 3.1 for a detailed explanation of each

mode.

1.4.2.1 Live Temperature Mode

This mode provides live temperature data streaming to the PC GUI. You can influence the temperature of

the device and see changes on the GUI.

1.4.2.2 FRAM Data Log Mode

This mode shows the FRAM data logging capabilities of the MSP430FR5994. After starting this mode, the

LaunchPad development kit wakes up every five seconds from sleep mode (indicated by LED blink) to log

both temperature and input voltage values. After reconnecting to the GUI, these values can be uploaded

and graphed in the GUI.

1.4.2.3 SD Card Data Log Mode

This mode shows the data logging capabilities of the MSP430FR5994 while interfacing with an SD card.

After starting this mode, the LaunchPad development kit wakes up every five seconds from sleep mode

(indicated by LED blink) to log both temperature and input voltage values. After reconnecting to the GUI,

these values can be uploaded and graphed in the GUI.

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. See Section 4 for available IDEs and

where to download them.

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

Tools. 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 development kit.

The out-of-box source code and more code examples are provided and available on the download page.

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 debug probe 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 Debug Probe With EnergyTrace++ Technology

To keep development easy and cost effective, TI's LaunchPad development kits integrate an onboard

debug probe, which eliminates the need for expensive programmers. The MSP-EXP430FR5994 has the

eZ-FET debug probe (see Figure 5), which is a simple and low-cost debugger that supports all MSP430

device derivatives.

Figure 5. eZ-FET Debug Probe

The MSP-EXP430FR5994 LaunchPad development kit features full EnergyTrace++ technology. The

EnergyTrace™ functionality varies across the MSP portfolio (see Table 1).

Devices Supported All MSP430 MCUs FR59 and FR69 MCUs

Development Tool Required MSP-FET or eZ-FET MSP-FET or eZ-FET

In Figure 5, the dotted line through J101 divides the eZ-FET debug probe from the target area. The

signals that cross this line can be disconnected by jumpers on J101, the isolation jumper block. For more

details on the isolation jumper block, see Section 2.2.3.

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. For more details, see Section 2.2.4.

Details of the eZ-FET hardware can be found in the schematics in Section 6 and in the hardware design

files download page. The software and more information about the debugger can be found on the eZ-FET

wiki.

2.2.3 Debug Probe Connection: Isolation Jumper Block

The isolation jumper block at jumper J101 can connect or disconnect signals that cross from the eZ-FET

domain into the MSP430FR5994 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 debug probe 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 development kit.

Figure 6 shows the pathway of the backchannel UART. The backchannel UART is the UART on

eUSCI_A0. This UART channel is separate from the UART on the 40-pin BoosterPack plug-in module

connector (eUSCI_A3).

On the host side, a virtual COM port for the application backchannel UART is generated when the

LaunchPad development kit 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).
