Introduction

This tutorial describes how to install and configure mspgcc, mspDebug and Eclipse to program and debug MSP430 microcontrollers on Windows.

What is needed?

  • Windows XP, Vista, 7 or later.
  • MSP430 USB FET Programmer

Step 1: Download

  • download Eclipse CDT for C/C++ developers from here
  • download the msp430 toolchain from here

Step 2: Install

  • Unzip eclipse file into some folder you like eclipse to be.e.g C:\eclipse
  • Open the zip file of msp430-toolchain and unzip the contents to C:\msp430-toolchain
  • Open eclipse and go to Help->Install New Software
    • add the following repository to eclipse: http://eclipse.xpg.dk
    • Install the MSP430 plugin and restart eclipse

Step 3: Configure Eclipse

  • Configure the toolchain in eclipse. Click the menu MSP430->Tool Manager
  • Add the toolchain which is installed in c:\msp430-toolchain or the folder you decided to use.
  • Click add and browse to the desired folder. After click Activate

Step 4: Compiling some code

  • In order to  use the MSP430 features, you have to create a new C or C/C++ project and choose "Empty Project" from the "MSP430 Cross Target Application" group.
  • Right click on the project and go to Properties
  • Select the MSP430 tab. Configure your msp430 platform (in my case msp430f2618 as Gina mote uses that uC)
  • Select tilib driver


  • To create a new source file click on the project folder and select new -> Source file. Name the file e.g main.c

  • Copy some testing code on it:

    sample code
    #include <io.h>
#include <stdint.h>
#include "msp430x26x.h" //use your msp430 configuration!

int main() {                    // The main function
    volatile uint8_t i = 0;
    WDTCTL = WDTPW + WDTHOLD;
    P2DIR |= 0x0F;
    // do forever:
    while (1) {
        i++;
        if (i == 0) {
            //toggle red led in gina
            P2OUT ^= 0x08;
        }
    }
}
  • In order to compile go to Project -> Build All or press Ctrl+B
  • To program the device go to MSP430 tab and select Upload to Target

Step 5: Debugging

  • To Debug with Eclipse click the Debug arrow near the Debug "bug – symbol" on the toolbar

  • Click Debug  button and wait the debugger to start. The code will stop at your main.

    NOTE: Make sure to Program the device before debugging using the MSP430 tab and Upload to Target option

Known Issues

  • If linker complains about the size of the code that is larger than the available ROM, use -Os compiler optimization flag.
