Kas makes the setup of a Yocto build environment super simple and super fast. We call kas with a project configuration file: kas-container build ./eu-terminal-distro.yml. Kas starts a Docker container, clones the layer repositories, initialises the Yocto configuration files (local.conf and bblayers.conf), and starts building the embedded Linux system. Most Linux BSP providers don’t make...
Is the Header Included from extern “C” Compiled as C or C++?
It depends! If a C++ source file includes the header inside an extern "C" section, the header is compiled as C++. If a C source file includes the header, the header is compiled as C. Hence, the header file should be both valid C and valid C++.

My Talk “A Successful Architecture for Qt Embedded Systems” at Qt Day Italy 2021
Creating an architecture means answering many questions about the ecosystem, in which the Qt embedded system operates. While the questions are very similar for all Qt embedded systems, the answers and their priorities differ. So, you should be able to transfer the questions and answers from my running example, a harvester terminal, to your system.

Burkhard on Qt Embedded Systems: No. 18
My May newsletter is all about system design and architecture. The trigger for my binge was the inspiring Software Architecture Workshop held by Ruth Malan and Dana Bredemeyer. I wrote two posts about the architecture of Qt embedded systems (more to come) and read the relevant parts of five books to understand the authors’ unique...
Architecture of Qt Embedded Systems: Single vs. Multiple GUI Applications
Our quest for a successful architecture of a harvester terminal continues. In this episode, we discuss when a system with a single application is good enough and when a system with multiple applications and a window manager is the better choice. Sometimes, a single-application system with a window manager is just the right choice.
Architecture of Qt Embedded Systems: Operating Conditions
Operator conditions like light, temperature, water, dust and vibration are a rich source for constraints and qualities of a system architecture. They affect the SoC, display and connector selection, the touch gesture recognition, the communication between system components, the cabling, the use of a window manager and more.
