Code Development Tools, Compilers, Debuggers & PC-side drivers

MSPGCC Toolchain [edit]

MSPGCC SourceForge 

The GNU C Compiler is an open source compiler and tool chain for compiling C code written in any coding environment into MSP430 machine code. Includes Binutils (as, ld) and tools for debugging and downloading the code (GDB, JTAG, BSL). GCC now supports MSP430 20-bit CPUx cores for firmware larger than 64kB (Beta)


MSPDEBUG SourceForge

MSPDebug is a free debugger for use with MSP430 MCUs. It supports FET430UIF, eZ430, RF2500 and Olimex MSP430-JTAG-TINY programmers, as well as many other compatible devices. It can be used as a proxy for gdb or as an independent debugger with support for programming, disassembly and reverse engineering. MSPDEBUG leverages the Open Source MSP Debug Stack (DDLv3).

Energia - Open source development environment[edit]

Energia github  |  Energia forums

Energia is branch of a popular open-source IDE & API framework that supports select MSP430 devices (MSP430G2553, MSP430G2452 & MSP430G2231 as of July 2012).

Energia runs on Windows, Mac OS X and Linux.

embedXcode - Unofficial Arduino Branch for MSP430 [edit]

GitHub  |  Website  |  Forum

embedXcode is a template for Xcode 4 and 5. It relies on the Processing-based Wiring-derived Arduino-like Energia IDE for the chain-tool and the core libraries. Because embedXcode is based on a modular set of makefiles, they can be used with other IDEs. I tested them on NetBeans successfully.

Latest release (115 onwards) includes external debugging, leveraging the LaunchPads' built-in hardware debugger: breakpoints are defined in Xcode and the debugging session runs on a Terminal window.

embedXcode requires Xcode 4 on Mac OS X 10.7 Lion and 10.8 Mountain Lion or Xcode 5 on Mac OS X 10.8 'Mountain Lion and 10.9 Mavericks.

InventorTown web-based code editor  [edit]  |  InventorTown forums

InventorTown is a web-based code editing tool that that allows you to edit the source code inside the web browser, and press a link to download the compiled binary firmware to your computer.

This editor is simpler than an installed development environment like CCS or IAR, but does not (yet) allow for debugging and similar advanced features. The editor is based on the Editarea component and MSPGCC.

MSP430 Flasher  [edit]

MSP430 Flasher is an open-source, shell-based interface for programming MSP430 devices through a FET programmer or eZ430 via JTAG or Spy Bi-Wire (SBW). MSP430 Flasher can be used to download binary files (.txt/.hex) files directly to the MSP430 Flash without the need of an IDE like CCS or IAR. It can also be used to extract firmware directly from a device, blow the JTAG fuse, and set hardware breakpoints.

MSP430 Flasher can run from any directory location and doesn't need to be installed. This makes it easy to provide an update option for new firmware.

The MSP430 Flasher itself is under BSD license, however the package also includes MSP430.dll and HIL.dll which are under "TI Proprietary"

MSPBSL Library [edit]

MSPBSL github  |  MSPBSL wiki

The MSPBSL Library is a project that is designed to allow developers to create PC-side Applications for Windows, Mac OS, and Linux without having to focus on lower level communication layers.This library is focused at developers who already have a degree of familiarity with the MSP430 Bootstrap Loader (BSL). For more information, on the MSP430 BSL, please visit our MSP430 BSL Wiki Page. This MSPBSL Library provides:

  • Cross-platform: Linux, MacOS, Windows compatible
  • Object Oriented C++
  • Able to support all 5xx devices currently, with an architecture able to support 1/2/4xx and 432 BSLs
  • Extensible to support future USB to UART/SPI/I2C bridges

This project was originally created in Microsoft Visual Studio Express 2010. This project is dependent on the following projects:


EasyMSP Google code repo | 43Oh Forum section

The EasyMSP project aims to enable "Fast, Easy, And affordable MSP430 Development". The project provides a C based framework that allows complete system abstraction and provides peripherals module libraries and drivers. As of August 2012, EasyMSP supports F2 Series, F5 Series and Value line devices.

EasyMSP currently only supports the CCS IDE.


The 4E4th-IDE for Windows is a totally Integrated Development Environment for 4E4th, including the 4E4th binary source, TI's LaunchPad_Driver.exe, MSP430Flasher.exe, TI's DLL's to establish 4E4th on the MSP430 LaunchPad, and a special Terminal emulation to correspond with 4E4th via a PC com port or virtual USB com port.

An Editor function is integrated to allow immediate incremental programming for one or more LaunchPad Projects. First Steps with 4E4th contain a brief description how to start programming from scratch, right out of the box.

Flash Emulation Tools & firmware


MSP Debug Stack [edit]

MSP Debug Stack wiki

The MSP debug stack (MSPDS) for all MSP430 devices is called MSP430.DLL. It consists of a dynamic link library as well as embedded firmware that runs on the MSP-FET430UIF or the eZ430 emulators. It is the bridging element between all PC software and all MSP430 microcontroller derivatives and handles tasks such as code download, stepping through code, break point handling and so forth. Examples that use the DLLv3 are IDEs such as Code Composer Studio (CCS), IAR's Embedded Workbench or others. Also other TI tools like Smart RF Studio or Elprotronic's FlashPro430 are using the MSP430.DLL.

Moreover, we're introducing a new USB protocol (CDC) for the MSP-FET430UIF debuggers, which will improve stability significantly and doesn't require any drivers except for an .inf file.

The latest MSP430.DLLv3 is an Open Source Package that has been created and tested on Windows and Linux and is available for for download.

Release notes and documentation are included in the DLL Open Source Package (SLAC460). This release supports the MSP-FET430UIF debugger, support for eZ430 emulators (i.e. MSP-EXP430G2 LaunchPad) is on the roadmap for a later point in time. MSP-FET430PIF emulators are not supported.

Open source MSP430 LaunchPad-based UART BSL interface[edit]

LaunchPad-based UART BSL Interface Application Note

This application report describes an open source implementation of the low cost, MSP-EXP430G2 LaunchPad-based MSP430 UART bootstrap loader (BSL) interface. The goal of the implementation is to deploy the MSP430 Value Line devices that have less than two serial interface modules as the bridge between the BSL Scripter software tool and the MSP430 target device.

Open MSP430 BSL Programmer [edit]

Open MSP430 BSL Programmer Project Info

Designed to work with the cross platform MSPGCC toolchain, the FCD-PRG01 provides an open source, cross platform alternative to platform dependent development tools for the MSP430 microprocessor.

The FCD-PRG01 integrates a USB-to-serial converter and on board regulated power supply into a small USB dongle, allowing programming and test capability over a single interface. It exposes a standard 6 pin, 0.1" header which can be used to interface to the target board via a device specific cable harness. This modular approach provides designers with the flexibility to select the optimal physical programming interface for the unique design constraints of each target platform.

Python BSL Module[edit]

Python Module for Flashing MSP430

This Python project is designed to facilitate programming the msp430 across many platforms. The input to the module is a TI-TXT that can be generated from CCS, IAR, or MSPGCC. The Flashing interfaces supported are HID BSL (F5x, F6x), UART BSL (Flash Based Devices), BSL (Rom Based Devices), and JTAG. This super lightweight package relies on the hidraw driver within linux which is compiled in by default in Ubuntu. This package can very easily be ported to the BeagleBone with a re-compile of the kernel in 5.06. As long as you have python installed, you can program, dump, erase, or calibrate any MSP430 from Unix, Linux, OSX, and Windows.

The MSP430 Graphics Library is a royalty-free set of graphics primitives for creating graphical user interfaces on MSP430 microcontroller-based boards that have a graphical display. The graphical library consists of two building layers of functionality: the display driver layer, specific to the display in use; and the graphics primitives layer, which draws points, lines, rectangles, circles, text, and bitmap images. The library is under a free BSD license and is available for royalty-free use

  • Note that the Image Reformer Utility component is not open source due to it's dependency on JRE.

BTStack - A portable open source bluetooth stack [edit]

MSP430 port BTStack

The aim of this project is to support devices for which the OS either does not provide a Bluetooth Stack or the available stack is severely limited (e.g., on the iPhone - more than 2.5 million installations). In addition, BTstack is well suited for small, resource-constraint devices such as 8 or 16 bit embedded systems as it is highly configurable and comes with an ultra small memory footprint. A minimal configuration for an SPP server on a MSP430 can run in 32 kB FLASH and only 4 kB of RAM.

MSP430 Core USB Stack[edit]

The USB Developers Package for MSP430 contains all necessary source code and example applications needed to create USB applications for HID, MSC, and CDC class devices. This package supports all F5xx and F6xx class MSP430's with integrated USB peripheral.
As of the 3.20.00 release, the core USB stack has been re-licensed with an open source BSD license. Please note the graphical Descriptor Tool is still under a TI-commercial license.

Egel project for MSP430 on Launchpad[edit]

MSP430 Egel project pages

The 'Egel project' consists of about 50 elementary examples of hardware control with the MSP430 in 
the language forth. In each example you find a file with forth code, documentation and links to 
more information on the internet.  

It is our aim to lower the hurdles that beginners with the MSP430 MPU find on their way to write programs using the MSP430 hardware.
With the many examples in the Egel project we hope to make it easier to understand the Texas Instruments documentation and to make good use of this elegant controller.

Examples of: I2C master & slave, SPI master & slave, Timer interrupts, Use of low power modes, 
and so on. Applications: From  a simple wireless datalogger, to using MSP430G2553 as BSL programmer, 
or walking biped, and so forth. Three new chapters were added recently, a walking hexapod, 128x64 
OLED screen driver & three lettersets finally a superior US-100 ultrasonic distance meter.
