Free & Downloadable Compilers/Debuggers (IDEs)
There are many other compilers and integrated development environments (IDEs) for MSP430 including Rowley Crossworks and MSPGCC. However, example projects have been created using IAR Embedded Workbench KickStart and Code Composer Studio (CCS). Both IAR and CCS have free, code-limited versions, which are available for download. These IDEs will run full-featured on the available MSP430 Value Line devices, as these devices will not encounter the 4kB size limit of IAR, or the 16kB size limit of CCS.
- Code Composer Studio (CCS) | Download Now (Requires TI Login)
- IAR Embedded Workbench KickStart | Download Now
The links above direct to free, code-limited versions. IAR Embedded Workbench KickStart is a free 4kB code-limited version and CCS v4 offers a free 16kB code-limited version. As MSP430 Value Line devices are below this limit, the free versions of each IDE will run full-featured on MSP430 Value Line devices.
IMPORTANT NOTICE FOR IAR-USERS GETTING STARTED: It's mandatory to set the target platform to your used MSP430Gxxx after creating a new project and to set the Debugger interface. To approach this follow these two steps: 1. Create a Project, then go to Project->Options->General Options->Target and choose the device you are using. 2. Go to Project->Options->Debugger and choose "FET Debugger" instead of "Simulator". Afterwards, everything should work fine and you'll be able to download and debug with IAR.
Linux Support
There is currently no official support for the Linux operating system. IAR Embedded Workbench does work under WINE in Ubuntu 10.04 but the LaunchPad itself doesn't map to a /dev/ttyUSB* port but rather to /dev/ACM0. Linking com1 under WINE to ACM0 doesn't allow for a debug connection through the IDE.
- Check out this detailed article from our friends @ Hack-a-Day! - How-to: LaunchPad programming with Linux
- Ramblings and Broken Code has an msp430-gcc tutorial that is geared toward Arch Linux users.
- eclecticc has a guide for Ubuntu users (you'll need to follow the instructions from MyLightSwitch on compiling mspgcc and mspdebug from source first).
- naken430asm is an open-source cross-platform assembler / disassembler / simulator that compiles and runs on Linux, MacOSX, and other OS's.

Pre-programmed Demo Application - Internal Temperature Measurement
[
LaunchPad includes a pre-programmed MSP430G2231 device. Once LaunchPad is connected via USB, the demo will start an LED toggle sequence. Pressing button P1.3 will start the Temperature Measurement mode.
A reference temperature is measured at the beginning of this mode, and can be re-calibrated with another button press on P1.3. LaunchPad signals a rising or falling temperature by varying the brightness of the on-board red or green LED, respectively. Temperature data is also communicated via back-channel UART through USB to the PC, which can be displayed using the provided GUI or a terminal on the PC.
This demo application is using the on-chip peripherals of the MSP430G2231 device, such as the 10-bit ADC to sample the internal temperature sensor and 16-bit timers, which drive the PWM to vary brightness of the LEDs and enable a software UART for communication with the PC.
The source code for this pre-loaded demo application is available for download in the #Complete_Projects section of the wiki. Also available are the executable and source files for a GUI, which displays the data that is being communicated back to the PC from the LaunchPad board.

Free & Downloadable Compilers/Debuggers (IDEs)
There are many other compilers and integrated development environments (IDEs) for MSP430 including Rowley Crossworks and MSPGCC. However, example projects have been created using IAR Embedded Workbench KickStart and Code Composer Studio (CCS). Both IAR and CCS have free, code-limited versions, which are available for download. These IDEs will run full-featured on the available MSP430 Value Line devices, as these devices will not encounter the 4kB size limit of IAR, or the 16kB size limit of CCS.
- Code Composer Studio (CCS) | Download Now (Requires TI Login)
- IAR Embedded Workbench KickStart | Download Now
The links above direct to free, code-limited versions. IAR Embedded Workbench KickStart is a free 4kB code-limited version and CCS v4 offers a free 16kB code-limited version. As MSP430 Value Line devices are below this limit, the free versions of each IDE will run full-featured on MSP430 Value Line devices.
IMPORTANT NOTICE FOR IAR-USERS GETTING STARTED: It's mandatory to set the target platform to your used MSP430Gxxx after creating a new project and to set the Debugger interface. To approach this follow these two steps: 1. Create a Project, then go to Project->Options->General Options->Target and choose the device you are using. 2. Go to Project->Options->Debugger and choose "FET Debugger" instead of "Simulator". Afterwards, everything should work fine and you'll be able to download and debug with IAR.
Linux Support
There is currently no official support for the Linux operating system. IAR Embedded Workbench does work under WINE in Ubuntu 10.04 but the LaunchPad itself doesn't map to a /dev/ttyUSB* port but rather to /dev/ACM0. Linking com1 under WINE to ACM0 doesn't allow for a debug connection through the IDE.
- Check out this detailed article from our friends @ Hack-a-Day! - How-to: LaunchPad programming with Linux
- Ramblings and Broken Code has an msp430-gcc tutorial that is geared toward Arch Linux users.
- eclecticc has a guide for Ubuntu users (you'll need to follow the instructions from MyLightSwitch on compiling mspgcc and mspdebug from source first).
- naken430asm is an open-source cross-platform assembler / disassembler / simulator that compiles and runs on Linux, MacOSX, and other OS's.

Pre-programmed Demo Application - Internal Temperature Measurement
[LaunchPad includes a pre-programmed MSP430G2231 device. Once LaunchPad is connected via USB, the demo will start an LED toggle sequence. Pressing button P1.3 will start the Temperature Measurement mode.
A reference temperature is measured at the beginning of this mode, and can be re-calibrated with another button press on P1.3. LaunchPad signals a rising or falling temperature by varying the brightness of the on-board red or green LED, respectively. Temperature data is also communicated via back-channel UART through USB to the PC, which can be displayed using the provided GUI or a terminal on the PC.
This demo application is using the on-chip peripherals of the MSP430G2231 device, such as the 10-bit ADC to sample the internal temperature sensor and 16-bit timers, which drive the PWM to vary brightness of the LEDs and enable a software UART for communication with the PC.
The source code for this pre-loaded demo application is available for download in the #Complete_Projects section of the wiki. Also available are the executable and source files for a GUI, which displays the data that is being communicated back to the PC from the LaunchPad board.
