Summary
In this chapter, we learned techniques that we can apply to create safer HAL code in C++. We covered the implementation of memory-mapped peripherals. The design utilizes templates and advanced techniques such as SFINAE, which we discovered in Chapter 8. We applied the knowledge from previous chapters in the embedded systems domain.
We also learned how to design classes that implement generic behavior and depend on traits classes to supply them with specific details. The code we developed is as efficient as a hand-coded (CMSIS-based) solution, thanks to the usage of templates and compile-time computations, enabling compiler optimizations.
In the next chapter, we will cover working with C libraries in C++.
