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’...

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....

Migrating a Harvester HMI from Qt 5.12 to Qt 6.0
December 2020 saw the launch of Qt 6 – the first new major version since 2012. I wanted to find out how fit Qt 6.0 is for Qt embedded systems. I took the driver terminal of the ROPA sugar beet harvesters and migrated it from Qt 5.12 to Qt 6.0 as a side project....

Architecture of Qt Embedded Systems: Getting Started
Which system-on-chip is best suited for your Qt embedded system? Should you build a custom Linux system with Yocto, use a container OS or a desktop Linux? Should you use Qt Commercial or Qt LGPLv3? How will the system be updated? What are the operating conditions of the system? How does the system communicate...
