Device Driver Writing Guide Quick Start

Conceptual information that a developer should know before creating a device driver.

A device driver is a program that controls a particular type of device that is attached to a base port. Writing a device driver requires an in-depth understanding of how the hardware and the software of a given platform function. The Device Driver writing guide tells you what you need and how to create a device driver.

  • For information about high-level implementation designs for your device driver, see Design Options.

  • For information about how device drivers are implemented as logical device drivers (LDDs) and physical device drivers (PDDs), see The LDD/PDD Model.

  • For information about organizing memory, managing data transfer across memory boundaries and the data transfer between LDD and PDD, see Memory Management.

  • For information about how device drivers use interrupts, see Interrupts .
