For systems programming, particularly in driver development using C, it's crucial to have comprehensive documentation on both the hardware and the operating system. Recommended resources include the O'Reilly book on Linux Drivers and the Windows Driver Development Kit (DDK), which provides essential guidance. Beginners are advised to start with simpler devices like joysticks and mice, utilizing standard API calls for interaction. Additionally, for embedded systems, the BASIC Stamp kit offers a practical starting point for interfacing with hardware. Overall, acquiring foundational knowledge through books is beneficial before exploring online resources.
