Summary
In this chapter, we delved into the core of bare-metal programming, emphasizing the direct interaction with microcontroller registers. This gave us insight into some of the key registers of our microcontroller and the structure of those registers.
We began by exploring various firmware development approaches, each offering a distinct level of abstraction. These approaches included the HAL, LL, Bare-Metal C programming, and the assembly language. This exploration helped us understand the trade-offs and applications of each approach in firmware development.
We spent a significant part of the chapter defining addresses of some peripherals using the official documentation. This step was important in creating addresses for various registers within those peripherals. It involved gathering specific memory addresses, typecasting them for register access, and creating aliases for bits in the registers.
The chapter culminated in a practical application where we configured PA5...
