STMicroelectronics provides the Reference Manual (RM0008) and Datasheet for free. While denser than a textbook, these are the primary sources the textbook is based on.
The text uses a systematic, step-by-step approach to teach programming for the popular , specifically focusing on its implementation on the affordable "Blue Pill" development board . Unlike many modern guides that rely heavily on abstraction layers (like HAL), this book emphasizes understanding the hardware at a lower level .
