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

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
