We change the code of our Qt application in QtCreator and press the Run button to try the changes on an embedded device. QtCreator cross-compiles the application, deploys it to the device and runs it on the device. QtCreator

Welcome to Episode 10 of my newsletter on Qt Embedded Systems! The newsletter goes out to more than 200 people for the very first, actually more than 215. Your amazing interest keeps me going. Thank you so much 🙏🙏🙏 The centre
A fairly common anti-pattern found in Qt applications is to derive a class MyApplication from QApplication and to have it hand out pointers to a dozen or more major components of the application. Similar to Qt's qApp
Welcome to Episode 9 of my newsletter on Qt Embedded Systems! In August, I evaluated the C++ dependency analyser CppDepend. I hoped that the tool would help me to find structural problems in the code of my current project. It
I evaluated the dependency analyser CppDepend on a real-life embedded application. My goal was to find all dependency cycles between classes in the application. I know that the application contains 50+ dependency cycles. CppDepend only found less than 10%
Welcome to Episode 8 of my newsletter on Qt Embedded Systems! On my current project, I am re-designing and re-implementing a core part of an embedded system with a pretty high spaghetti factor. So, I decided to re-
Welcome to Episode 7 of my newsletter on Qt Embedded Systems. This newsletter goes out now to over 150 people 🙏 Don't miss out on my webinar on 8 July 2020 about cross-building Qt application from QtCreator using
