MSP430 RTC Temperature Compensation
William Hugh Molesworth, San Diego, California
Featured device: MSP430FG439

Description: This entry provides a solution to the frequently asked question, how do I make my clock more accurate? Of course, secondary requirements are that this accuracy is achieved using no additional power and for zero additional cost. The generic term is Real Time Clock (RTC). This example is based on the Retro Watch Development Kit, and can easily be ported.

Software correction is the way to go, since it costs nothing in hardware and can be designed to minimize additional power consumption by doing as little as possible as least often as possible. Code and data size are often also important issues, and not just power consumption, so a variety of solutions are shown.
