Windows Driver Development Course (5 Days)

Course Introduction:

The Windows Driver Foundation (WDF) is the latest standard for creating Windows drivers, and is the preferred way to implement most new drivers for Windows.

This workshop is designed for engineers who need to understand how to design, develop, and test Windows drivers using the WDF Kernel Mode Driver Framework (KMDF). The seminar specifically focuses on providing practical experience in developing KMDF software drivers. Once an attendee understands these concepts, creating KMDF drivers for other classes.

Engineers who need to understand how to design, develop, and test Windows drivers using the Windows Driver Foundation's (WDF) Kernel Mode Driver Framework (KMDF).

Prerequisites:

Students attending this seminar must have solid knowledge of general operating systems concepts (user mode versus kernel mode, virtual memory concepts, concurrency issues), device concepts (registers, interrupts), and the basics of Windows O/S Architecture. Previous experience developing device drivers (on any operating system) will definitely be an advantage.

Due to the hands-on orientation of this seminar, attendees will be assumed to be able to use Windows at a user level, including using Microsoft's Developer's Studio (VC++). Working knowledge of the C programming language, and how to read and write to a file using Win32 (CreateFile, ReadFile, WriteFile) are also assumed. Some familiarity with Windows OS configuration (Registry, System Administration Tools and System Directories etc) is required.
