Design Kits and Evaluation Modules

MSP430FR2476 LaunchPad™ development kit

The LP-MSP430FR2476 LaunchPad development kit is an easy-to-use evaluation module (EVM) based on the MSP430FR2476 value line sensing microcontroller (MCU). It contains everything needed to start developing on the ultra-low-power MSP430FR2x value line sensing MCU platform, including on-board debug probe for programming, debugging and energy measurements.

Target development board for MSP430FR2476 MCU

The MSP-TS430PT48A microcontroller development board is a standalone ZIF socket target board used to program and debug the MSP430 in-system through the JTAG interface or the Spy Bi-Wire (2-wire JTAG) protocol. This development board supports the MSP430FR2476 FRAM devices in a 48-pin QFP package (TI package code: PT).


MSP430Ware™ Software

MSP430Ware software is a collection of code examples, data sheets, and other design resources for all MSP430 devices delivered in a convenient package. In addition to providing a complete collection of existing MSP430 design resources, MSP430Ware software also includes a high-level API called MSP430 Driver Library. This library makes it easy to program MSP430 hardware. MSP430Ware software is available as a component of CCS or as a stand-alone package.

MSP430FR267x, MSP430FR247x Code Examples

C code examples that configure each of the integrated peripherals for various application needs.

MSP Driver Library

The driver library's abstracted API keeps you above the bits and bytes of the MSP430 hardware by providing easy-to-use function calls. Thorough documentation is delivered through a helpful API guide, which includes details on each function call and the recognized parameters. Developers can use driver library functions to write complete projects with minimal overhead.

MSP EnergyTrace™ Technology

EnergyTrace technology for MSP430 microcontrollers is an energy-based code analysis tool that measures and displays the application’s energy profile and helps to optimize it for ultra-low-power consumption.

ULP (Ultra-Low Power) Advisor

ULP Advisor™ software is a tool for guiding developers to write more efficient code to fully utilize the unique ultra-low power features of MSP and MSP432 microcontrollers. Aimed at both experienced and new microcontroller developers, ULP Advisor checks your code against a thorough ULP checklist to squeeze every last nano amp out of your application. At build time, ULP Advisor will provide notifications and remarks to highlight areas of your code that can be further optimized for lower power.

FRAM Embedded Software Utilities for MSP Ultra-Low-Power Microcontrollers

The FRAM Utilities is designed to grow as a collection of embedded software utilities that leverage the ultra-low-power and virtually unlimited write endurance of FRAM. The utilities are available for MSP430FRxx FRAM microcontrollers and provide example code to help start application development. Included utilities include Compute Through Power Loss (CTPL). CTPL is utility API set that enables ease of use with LPMx.5 low-power modes and a powerful shutdown mode that allows an application to save and restore critical system components when a power loss is detected.

IEC60730 Software Package

The IEC60730 MSP430 software package helps you comply with IEC 60730-1:2010 (Automatic Electrical Controls for Household and Similar Use – Part 1: General Requirements) for up to Class B products, which includes home appliances, arc detectors, power converters, power tools, e-bikes, and many others. The IEC60730 MSP430 software package can be embedded in applications that run on MSP430 MCUs to help simplify the certification efforts of functional safety compliant consumer devices to IEC 60730-1:2010 Class B.

Fixed-Point Math Library for MSP

The MSP IQmath and Qmath Libraries are a collection of highly optimized and high-precision mathematical functions for C programmers to seamlessly port a floating-point algorithm into fixed-point code on MSP430 and MSP432 devices. These routines are typically used in computationally intensive real-time applications where optimal execution speed, high accuracy, and ultra-low energy are critical. By using the IQmath and Qmath libraries, it is possible to achieve execution speeds considerably faster and energy consumption considerably lower than equivalent code written using floating-point math.

Floating-Point Math Library for MSP430

Continuing to innovate in the low power and low cost microcontroller space, TI brings you MSPMATHLIB. Leveraging the intelligent peripherals of our devices, this floating point math library of scalar functions brings you up to 26x better performance. Mathlib is easy to integrate into your designs. This library is free and is integrated in both Code Composer Studio IDE and IAR Embedded Workbench IDE.

Development Tools

Code Composer Studio™ Integrated Development Environment for MSP Microcontrollers

Code Composer Studio integrated development environment (IDE) supports all MSP microcontroller devices. Code Composer Studio IDE comprises a suite of embedded software utilities used to develop and debug embedded applications. It includes an optimizing C/C++ compiler, source code editor, project build environment, debugger, profiler, and many other features.

IAR Embedded Workbench® IDE

IAR Embedded Workbench IDE for MSP430 MCUs is a complete C/C++ compiler toolchain for building and debugging embedded applications based on MSP430 microcontrollers. The debugger can be used for source and disassembly code with support for complex code and data breakpoints. It also provides a hardware simulator that allows debugging without a physical target connected.

Uniflash Standalone Flash Tool

CCS Uniflash is a stand-alone tool used to program on-chip flash memory on TI MCUs. Uniflash has a GUI, command line, and scripting interface. Uniflash is a software tool available by TI Cloud Tools or desktop application download from the TI web page.

MSP MCU Programmer and Debugger

The MSP-FET is a powerful emulation development tool – often called a debug probe – that lets users quickly begin application development on MSP low-power microcontrollers (MCU). Creating MCU software usually requires downloading the resulting binary program to the MSP device for validation and debugging. The MSP-FET provides a debug communication pathway between a host computer and the target MSP. Furthermore, the MSP-FET also provides a backchannel UART connection between the computer's USB interface and the MSP UART. This affords the MSP programmer a convenient method for communicating serially between the MSP and a terminal running on the computer.

MSP-GANG Production Programmer

The MSP Gang Programmer can program up to eight identical MSP430 or MSP432 flash or FRAM devices at the same time. The MSP Gang Programmer connects to a host PC using a standard RS-232 or USB connection and provides flexible programming options that allow the user to fully customize the process. The MSP Gang Programmer is provided with an expansion board, called the Gang Splitter, that implements the interconnections between the MSP Gang Programmer and multiple target devices.

TIREX Resource Explorer (TIRex)

An online portal to examples, libraries, executables, and documentation for your device and development board. TIRex can be accessed directly in Code Composer Studio IDE or in TI Cloud Tools.
