Learn to debug msp430 chips using IAR

If you haven’t done any debugging with microcontroller programs [Kphlight] posted a follow-along guide for debugging MSP430 chips. You can see above that he’s using the TI Launchpad and has chosen the free (but code limited) IAR Embedded Workbench that is one of the IDE’s that TI provides for the kit. The example builds a Pomodoro timer with just five LEDs and one resistor. You’ll flash the code to the chip, step through each line of the firmware, and learn how to manipulate register data during code execution.

It’s a great primer for the uninitiated, and we’d love to see one using open-source tools like DDD and GDB. If you do write one, don’t forget to send us a tip about it. If you want to give open source a try with this hardware check out our own tutorial.

    Loving the picture with the paper clip!

    yea, i’m glad i’m not the only one who uses paperclips when prototyping :)

    I prefer CCS over IAR. Kphlight, have you used both? If so, I’m wondering why you prefer IAR? I’m not saying CCS is better. I’m just wondering if I should give IAR another look.

    more and more IAR seems to be AIR intentionally misspelled

  5. Reminds me, I probably should take my TI launchpad out of its box and use it for something.

    Oh good timing, a couple weeks ago I ordered two Launchpads for my first ever foray into microcontroller programming. Debugging resources are a plus!
