This MSP430 Reference is managed by Peter Johansson. I am primarily a software engineer, but I have dabbled in hardware on and off over the years going all the way back to elementary school. In years past I have done small projects using PICs and AVRs. I recently started a project to build a small, inexpensive, apogee detection device for my model rockets. Both the apogee detector as well as the rocketry project in general are sub-parts of a much larger project, and in this realm I believe the MSP430 to be a better solution than PIC or AVR.
This is not intended to be a definitive listing of all material about the MSP, merely a collection of the bits I feel most useful and/or important.
