Welcome to Episode 4 of my newsletter on Qt Embedded Systems. I hope this episode finds you alive and kicking despite the COVID-19 pandemic. Bavaria has been under curfew for 11 days and will be for at least another 19
In my recent post Benefits of a Relocatable Qt, I explained how to relocate Qt from a build server to a developer PC and from the PC to an embedded system. Qt is installed in three different locations. My solution
Welcome to Episode 3 of my newsletter on Qt Embedded Systems. I lead this episode with my thoughts about a better pricing model for Qt. What price would you be willing to pay for Qt and why? I am keen
Bob builds Qt for the development team on a fast compute server. He packs Qt into a tarball and hands the tarball to his teammates. Alice installs the Qt tarball on her PC in a directory that differs from the
From Qt 5.15, The Qt Company make their offering a bit more inconvenient for FOSS users. They announced three changes: * A Qt account is mandatory to download binary Qt packages. The offline installer is not available to FOSS users
Welcome to my newsletter on Qt Embedded Systems. In my monthly newsletters, I cover a large spectrum of topics needed to build Qt applications on embedded systems. Topics include UI design, QML, Qt, C++, Yocto, system-on-chips, system architecture, agile practices
Two years ago, I spent three days to figure out why the driver terminal of a sugar beet harvester crashed (see my original post). The crash happened after going through the same six-step interaction at least four times. The reason
In the early days of controller area networks (CAN), every device manufacturer interpreted CAN frames in its own proprietary way. When you changed the engine of a harvester from Volvo to MAN, you would have to reimplement the communication with
The little known KDE Free Qt Foundation makes sure that Qt stays free and open-source. It guarantees that all Qt modules currently licensed under LGPLv3 must continue to be available under LGPLv3 in the future. This covers all modules from
