In this chapter, we looked at the myriad ways in which the Qt framework can be used to develop for embedded systems. We briefly looked at how it compares with other frameworks and how Qt is optimized for these embedded platforms, before working through an example of a QML-based GUI that could be added to the infotainment system we previously created.

You should now be able to create basic Qt applications, both purely command line-based and with a GUI. You should also have a clear idea of which options Qt offers to develop GUIs with.

In the next chapter, we will be taking a look at the next evolution of embedded platforms, using field-programmable gate arrays (FPGAs) to add custom, hardware-based functionality to speed up embedded platforms.
