A Mock QCanBusDevice for TDD
I am using TDD to implement a hardware-independent mock QCanBusDevice. We can use MockCanBusDevice in unit, integration and acceptance tests – without access to a… Read More »A Mock QCanBusDevice for TDD

Developing a QML Keypad with TDD
Although Qt comes with a unit-test framework QuickTest for QML code, hardly any QML GUIs are unit-tested, let alone developed with TDD (test-driven development). One… Read More »Developing a QML Keypad with TDD
My Talk “Hexagonal Architecture: The Standard for Qt Embedded Applications” at Meeting Embedded 2021
I gave a talk at Meeting Embedded 2021 on 4 November 2021. First, I introduced the hexagonal architecture (a.k.a. ports-and-adapters architecture) in general. Then, I showed a walking skeleton of the architecture for a harvester terminal.

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.

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.

Showing Wayland Compositor Fullscreen in Portrait Orientation
Our Qt embedded system is displayed on a monitor mounted in portrait orientation. The system runs the Wayland compositor Weston as a window manager. HMI applications are shown rotated by 90 degrees – in landscape orientation. The system toolbar of Weston is visible. How can we configure Weston so that the applications are shown in portrait orientation and so that the system toolbar is removed?
