Arm Cortex-M processors offer versatile interrupt priority management but the multiple priority numbering conventions can lead to bugs. I explain the subject and cut through the confusion.

What exactly is rapid prototyping ?Sometimes we get some great ideas; some ideas are forgotten due to it took too long to build other ideas.But if we could just build our circuits as quickly as they came…

The subject of digital filtering is vast but the basics can be understood fairly easily. In this post we cover this subject to help your understanding of the topic.

There are 10 easy steps that can be followed to ensure that the right choice is made for a microcontroller. See the full list in this post.

In the last few months we have passed an important milestone for DSP and a smaller but for some no less important announcement of tools that can help build DSP systems. In some small way I’ve been involved…

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…

If you have a large source code and want to compile it frequently you can use a cross-compiler. In this post we discuss how this method can be done.

Recently, I wrote an article called “Navigating the Cortex Maze” (Navigating the Cortex Maze) That was intended as an easy way-in to the ARM processor range, covering Cortex-A (architecture…

Hi,Just noticed jacobbeningo's excellent post (10 Tips for Maximizing Battery Life)  in Embedded on Maximizing Battery Life. Some really good advice which any designer should take note of. Thanks…

Portable, battery powered devices are sweeping through society like wild fire.  Mobile computing and sensor devices are springing up everywhere providing engineers with not only a plethora of data but…

ARM architecture is supported by all popular RTOS vendors in embedded. Here is a table showing the RTOS companies, their products, and an indication of which ARM processors they support.

A couple of weeks ago Atmel launched the SAM D20 family of products with a comprehensive roll-out of product information, including one of the most impressive of uses that I have seen in a while of all…

Stack buffer overflows are an all too common failure mode in embedded systems where a program accidentally, or maliciously, overwrites fixed-length buffers on the call stack resulting in loss of system…

Chinese Version 中文版：CoreMark 和编译器性能CoreMark is quickly gaining traction as the de facto benchmark for CPU performance. It is freely available, easy to compile and run, and returns a single value result…

This is an exciting time for consumers as they anticipate a further step change in their mobile computing experience, and in the supporting infrastructure. To support the launch of the new ARM® Cortex…
