This application report describes a low-power pedometer example application that uses an MSP430F5229 microcontroller and the TI Pedometer firmware algorithm. This application was developed and targeted for the health and fitness markets. Fitness monitors typically measure both a person's amount and rate of exercise (traveled distanced and pace) as well as effort expended (calories burned in the process through the number of steps taken). Stored data such as steps and calories can be downloaded to a computer via USB or a wireless USB dongle. All parts of the system require ultra-low power embedded controllers and low-power RF for communications. An MSP430™ microcontroller implementing the TI pedometer firmware combined with a low-power 3-axis MEMS accelerometer provides a low-power pedometer solution.
