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 – Building Your Own Internet Connected PLC

Programmable Logic Controllers (PLC’s) are the foundation for manufacturing and the industrial IoT. Developers are probably used to purchasing off-the-shelf PLC controllers, but it is possible to build a simple low-cost PLC controller using microcontroller components. In this course, we will explore PLC fundamentals and how we can create our own internet connected PLC controller … Continue reading CEC – Building Your Own Internet Connected PLC

Know thy compiler toolchain

An embedded systems engineer is only as good as their knowledge of the tools they use. Using the right tool for the job can drastically speed up development but doesn’t necessarily ensure success. The developer needs to understand the intricacies of the tool in order to be successful. Take for example an apparently simple task … Continue reading Know thy compiler toolchain

Tools – The Otii Arc, a Smart Power Supply for Optimizing Embedded Systems

The ability to optimize an embedded system for how much energy it uses can have profound benefits. For example, a deployed IoT device may not require maintainers to visit the site for an additional 6 months or the development team may be able to decrease the size and weight of the battery which could product … Continue reading Tools – The Otii Arc, a Smart Power Supply for Optimizing Embedded Systems

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

5 Trends from Embedded World 2018

Last week, I attended the 2018 Embedded World conference in Nuremberg Germany (February 27 – March 1). As usual, companies from around the world descended on Nuremberg to show off their latest and greatest embedded technologies. While I was there giving several talks, networking with colleagues and walking the conference floor, I started to see … Continue reading 5 Trends from Embedded World 2018
