Many embedded applications have reached a complexity level that requires them to use a real-time operating system (RTOS) to manage task timing, memory and many other activities within the application. Using an RTOS can be a welcome component to help simplify development but at the same time, an RTOS can add complexity and the potential … Continue reading Simplify Debugging using RTOS Aware Debugging

5 RTOS Best Practices for Designing RTOS-Based Applications
I often see developers struggling to properly write applications that use an RTOS. These struggles range from properly determining how many tasks to have in their system, how to set their priorities, coordinate task behavior, avoid common pitfalls and sometimes just making the application work! Nearly two-thirds of all embedded systems use an RTOS today … Continue reading 5 RTOS Best Practices for Designing RTOS-Based Applications
The Big Tech Cloud Wars Ramifications on the Embedded Industry
Several years ago, Amazon acquired the open source operating system FreeRTOS(TM) and with it, launched a new operating system named Amazon FreeRTOS(TM)? which provides developers working on IoT devices an integrated path to connect with Amazon Web Services (AWS). The idea seems simple, provide developers with a free method to connect to the cloud and … Continue reading The Big Tech Cloud Wars Ramifications on the Embedded Industry
7 Tips for Getting Started with Amazon FreeRTOS
Nearly every company at this moment is rushing to connect their products to the internet. The IoT has become the modern-day gold rush only the gold is data. Companies are discovering that by connecting their devices, they aren’t only able to change to a subscription-based business model but can innovate their products in ways they … Continue reading 7 Tips for Getting Started with Amazon FreeRTOS
Tools – Real-time Application Visualization Using Tracealyzer 4.2
It has often been said that a picture is worth a thousand words. When it comes to debugging embedded software, a picture is worth a hundred thousand lines of code. For most of my career, I’ve always felt apprehensive about running code on a target and verifying a few external features to say that the … Continue reading Tools – Real-time Application Visualization Using Tracealyzer 4.2
3 Ways to Perform a Worst-Case Stack Analysis
Figuring out how to size the stack for an embedded application and the tasks within it can be challenging. In many cases, developers will pick a value that they feel should be enough. These estimates are sometimes a little short, most of the time a gross estimation and rarely spot on. While I always encourage … Continue reading 3 Ways to Perform a Worst-Case Stack Analysis
Amazon FreeRTOS: Behind the Scenes
I recently wrote an article for embedded.com entitled “A Peek Inside Amazon FreeRTOS” where I started to analyze the high-level behavior that the Amazon FreeRTOS application exhibits while running on an STM32F475 IoT Discovery Node. In this post, I will continue the analysis by demonstrating how a developer can follow the communication flow and examine … Continue reading Amazon FreeRTOS: Behind the Scenes
CEC – Connecting Edge Devices to the IoT using Amazon FreeRTOS
Amazon FreeRTOS is a new operating system designed help embedded software developers easily connect their devices to Amazon Web Services (AWS). Amazon FreeRTOS is based on the popular open source FreeRTOS kernel but extends those capabilities by providing developers with connectivity libraries such as MQTT, TLS, device provisioning and even firmware updates. In this course, … Continue reading CEC – Connecting Edge Devices to the IoT using Amazon FreeRTOS

Successfully creating an IoT device requires developers to master their RTOS and debugging techniques in addition to learning about internet connectivity. In this webinar, attendees will learn about advanced … Continue reading Designing and Debugging RTOS based IoT Applications
Embedded Basics – 7 Tips for Managing RTOS Memory Performance and Usage
There are two excuses that I typically hear from developers on why they refuse to use a RTOS: • An RTOS memory footprint is too big • The RTOS has too much overhead These excuses might have had some merit five years ago but today they hold no weight. A typical RTOS will load the … Continue reading Embedded Basics – 7 Tips for Managing RTOS Memory Performance and Usage
