RTEMS C User's Guide
Device drivers consist of control software for special peripheral devices and provide a logical interface for the application developer. The RTEMS I/O manager provides directives which allow applications to access these device drivers in a consistent fashion. A Board Support Package may include device drivers to access the hardware on the target platform. These devices typically include serial and parallel ports, counter/timer peripherals, real-time clocks, disk interfaces, and network controllers.
For more information on device drivers, refer to the I/O Manager chapter.
