Overview

The estimated power usage of the example application varies from 100-141 mW. This will vary based on component tolerances and any user added code and/or user added compile options.

Note that these are typical usage statistics for a representative run of the application on hardware. Core allocations may shift run-to-run in a scheduled RTOS. These statistics are generated by slicing the representative run into 10 ms chunks and calculating % time per chunk not spent in the FreeRTOS IDLE tasks. Therefore, the underlying distribution of these 10 ms bins should not be assumed to be Normal; this has implications on e.g. the interpretation of the Standard Deviation given here.
