5.2.3. Applications versus Drivers

Application developers are responsible for writing the system’s main() routine, among other routines. Applications interact with system resources either through the C standard library, or through the HAL API. Device driver developers are responsible for making device resources available to application developers. Device drivers communicate directly with hardware through low-level hardware access macros.

For further details about the HAL, refer to the "Developing Programs Using the Hardware Abstraction Layer" and "Developing Device Drivers for the Hardware Abstraction Layer" chapters.
