I would just like to take a moment to let MSP430 users know about a blog post and white paper I've written about unit testing with the MSP430. I've been developing with the platform for about 2 years now, and all of my development has been test-driven, where a continuous build system runs unit testing upon every commit.
I've found it extremely useful to develop in this manner, and with a few tricks, unit testing interrupts and timers can be accomplished within a desktop environment.
The link can be found here: e2e.ti.com/.../unit-testing-the-msp430-within-a-desktop-environment
Please don't hesitate to ask any questions within this thread or the blog post.
