Optimize MCU Code for Low Energy Operation

December 2, 2011 3:55 am | by Rasmus Christian Larsen, Energy Micro, www.energymicro.com | Articles | Comments

Once you’ve selected the right low power microcontroller, how important is your application code in achieving energy saving and efficiency goals? And how do you go about optimizing it for ultra low power operation? Answering such questions has always been difficult, since correlating current consumption with software code has traditionally been a somewhat inexact and cumbersome task.
