Microsoft Windows Embedded CE 6.0 Exam Preparation KitRegardless of hardware specifics, all CE stream drivers expose the stream interface functions to the operating system so the Device Manager of Windows Embedded CE can load and manage these drivers. As the name implies, stream drivers are suitable for I/O devices that act as sources or sinks of streams of data, such as integrated hardware components and peripheral devices. It is also possible for a stream driver to access other drivers to provide applications with more convenient access to the underlying hardware. In any case, you need to know the stream interface functions and how to implement them if you want to develop a fully functional and reliable stream driver. After this lesson, you will be able to: в– В Understand the purpose of Device Manager. в– В Identify stream driver requirements. в– В Implement and use a stream driver. Estimated lesson time: 40 minutes. Device Manager The Windows Embedded CE Device Manager is the OS component that manages the stream device drivers on the system. The OAL (Oal.exe) loads the kernel (Kernel.dll), and the kernel loads Device Manager during the boot process ...» |
