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.

Until now my newsletter went out on the last day of the month. From now on, I’ll send out the newsletter on the first Monday of the month. On the Friday before, I’ll announce the contents of the newsletter on my blog (this post). This gives me at least one weekend to write the newsletter...
Using Qt 5.15 and Qt 6 under LGPLv3
Nearly exactly 5 years ago, I wrote my first article about Using Qt 5.6 and Later under LGPL. The trigger then was the switch from LGPLv2.1 to LGPLv3 with Qt 5.6. The trigger now is the switch from Qt 5 to Qt 6. All the Qt modules under LGPLv3 5 years ago are still available...

How to Set Up QtCreator for Cross-Compilation with CMake in 5 Minutes
Setting up QtCreator for cross-compilation with CMake took me 15-20 hours the first two or three times. The next half a dozen times took me 4 hours on average. The last two times took me 5 minutes – using the script presented in this post. I can cross-compile the Qt application for my embedded device...
