Design Kits and Evaluation Modules

    3-Phase Electronic Watt-Hour EVM for Metering (EVM430-F6779)

    This EVM430-F6779 is a three-phase electricity meter evaluation module based on the MSP430F6779A device. The E-meter has inputs for three voltages and three currents, as well as an additional connection to demonstrate antitampering. The EVM lets you test the new F677x, F674x, F676x, F677x1, F674x1, F676x1 series and see the accuracy results, wide dynamic range achieved, and ease of calibration. The easy-to-use Energy Library provides metrology software for fast startup with this EVM. The software is also programmable for any user’s needs.

    Three-Phase Metrology With Enhanced ESD Protection and Tamper Detection Reference Design

    This design implements an ANSI/IEC Class 0.2 three-phase energy meter with enhanced ESD protection. The design also features tamper detection to limit the feasibility of energy theft and communications through ZigBee connectivity. The e-meter SoC is used to perform all metrology functions and sends active power results to the CC2530EM add-on board. Developers can use the companion In Home Display TI Design (TIDM-LOWEND-IHD) to display results remotely.

Software

    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 MSP 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.

    Energy Measurement Design Center for MSP430 MCUs

    The Energy Measurement Design Center is a rapid development tool that enables energy measurement using TI MSP430i20xx and MSP430F67xx flash-based microcontrollers (MCUs). It includes a graphical user interface (GUI), documentation, software library, and examples that can simplify development and accelerate designs in a wide range of power monitoring and energy measurement applications, including smart grid and building automation. Using the Design Center, you can configure, calibrate, and view results without writing a single line of code.

    MSP Driver Library

    The abstracted API of MSP Driver Library provides easy-to-use function calls that free you from directly manipulating the bits and bytes of the MSP430 hardware. 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 energy profile of the application 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 use 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 help minimize the energy consumption of your application. At build time, ULP Advisor provides notifications and remarks to highlight areas of your code that can be further optimized for lower power.

    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 provides MSPMATHLIB. Leveraging the intelligent peripherals of our devices, this floating-point math library of scalar functions that are up to 26 times faster than the standard MSP430 math functions. 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 (CCS) integrated development environment (IDE) supports all MSP microcontroller devices. CCS 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.

    Command-Line Programmer

    MSP Flasher is an open-source shell-based interface for programming MSP microcontrollers through a FET programmer or eZ430 using JTAG or Spy-Bi-Wire (SBW) communication. MSP Flasher can download binary files (.txt or .hex) directly to the MSP microcontroller without an IDE.

    MSP MCU Programmer and Debugger

    The MSP-FET is a powerful emulation development tool – often called a debug probe – which lets users quickly begin application development on MSP low-power MCUs. Creating MCU software usually requires downloading the resulting binary program to the MSP device for validation and debugging.

    MSP-GANG Production Programmer

    The MSP Gang Programmer is an MSP430 or MSP432 device programmer that 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 let the user fully customize the process.
