3.1 Low-Power Application

This use case uses a megaAVR® device to introduce you to the Power Debugger. Using the tool with Atmel Studio and Data Visualizer, we learn how it can be used to measure, analyze, understand, and optimize the power consumption of a typical low-power application. We also look at an example of code instrumentation using the Data Gateway Interface.

Important: The Data Visualizer used in this use case should not be confused with the MPLAB Data Visualizer. These two applications have a similar feature set and the Power Debugger also works with the MPLAB Data Visualizer, but the user interface is totally different. The Data Visualizer referred to in this use case was originally named Atmel Data Visualizer.

The example makes use of the ATmega328PB Xplained Mini Board, but could very easily be adapted to suit any simple custom board.
