This article explains how we wrote data to flash during program execution when developing the batteryless energy harvesting remote control. This remote control used an MCU from the Freescale KL25z series…

This blog post is concerned with how we got the MCU in the Batteryless Energy Harvesting Remote Control to go into a Low Leakage Mode. It is also concerned with the Low Leakage Wake Up Unit (LLWU) and…

The Batteryless Energy Harvesting Remote Control can be taught Infra-red codes and then repeat them. This post explains the way in which this was achieved.Learning Infrared codesThe circuit uses an Infra…

This post is concerned with the techniques used to harvest and regulate energy for the Energy Harvesting Remote Control.Sources of Energy Harvested:The main source of energy harvested in the remote control…

The Concept:The batteryless energy harvesting remote control was a project undertaken to demonstrate the low power of the ARM Cortex-M0+ processor. We wanted to create an extremely low power remote control…

Analysing PerformanceWhen we talk about optimizing performance, we could mean a number of different things. The first thought that comes to most people’s minds in the context of a gaming application is…

Size mattersHow much does it take to increment a number? One instruction? Two? It is not as simple a question as you might imagine. And, believe me, this is one case where size matters.On an ARM processor…

I particularly like this case study that I found over on edn.com for two reasons; 1) it is nice and detailed and explains the underlying science of a heart monitor that I'd never read before, and 2) I…

Part 4 in a four part blog describes a more systematic approach to measuring and validating the system performance of these types of systems and introduces new tools to make this systematic approach practically…
