Hands-On Embedded Programming with C++17

Summary

In this chapter, we looked at OS-based embedded systems, exploring the many operating systems available to us, with the most significant differences, especially those of real-time operating systems. We also saw how one would integrate an RTC peripheral into an SBC-based Linux system and explored user space- and kernel space-based driver modules, along with their advantages and disadvantages.

Along with the example project in this chapter, the reader should now have a good idea of how to translate a set of requirements into a functioning OS-based embedded system. The reader will know how to add external peripherals and use them from the OS.

In the next chapter, we will be looking at developing for resource-restricted embedded systems, ...
