ABSTRACT
The MSP430 family of low-power microcontrollers are ideal for low-power smart-sensor applications. This application report describes a method for interfacing an accelerometer to an MSP430F2012, creating a microcontroller-based dual-axis tilt sensor. Using efficient hardware and software design practices, the MSP430 directly interfaces with an accelerometer and drives 12 LEDs with 6 port pins to illuminate the LED oriented at the highest point when the board is tilted.
