It used to be if you were developing embedded systems, you were a C programmer. Boy, have things changed. Arduino is a C++ environment, and Python is everywhere. More recently, the Rust programming language has grown in popularity to bring the total number of embedded programming languages to more than we can keep track of. […]

In this Learning Hour, Umesh Lokhande will: • Cover concepts like MQTT Broker, Publisher, Subscriber, etc. • Work on MQTT Protocols with QoS 0, 1, 2 • Review MQTT Clients: MQTTFx (Web), MyMQTT (Mobile) • Example project: Live Controlling and Monitoring sensor data

If you're a student, hobbyist, or serious embedded developer, you have had ample experience with UART. After all, it's the de facto serial communications protocol for connecting target development platforms to your development PC! But what about UART driver development? How versed in that are you? Regardless of the answer, in this week's Engineering Hour […]

In this lesson, DevHeads' embedded Linux experts will take us into fundamental concepts that form the backbone of Yocto, Poky, and OpenEmbedded. Understanding these differences is crucial for navigating the world of embedded systems development effectively. What is Yocto? Yocto is not just a single entity but rather a collection of tools and metadata used […]
