5.2.4.2. Benefits to Application Developers

The HAL defines a set of functions that you use to initialize and access each class of device. The API is consistent, regardless of the underlying implementation of the device hardware. For example, to access character-mode devices and file subsystems, you can use the C standard library functions, such as printf() and fopen(). For application developers, you need not write low-level routines just to establish basic communication with the hardware for these classes of peripherals.
