In contrast to the native drivers, the stream interface drivers all share a common interface composed of 10 functions, or entry points, within each driver.

The three-letter prefix can be any combination of uppercase letters, but it must be unique on a given platform.When an application opens a file that follows this convention, the file system module recognizes that a driver is being accessed and re-routes subsequent file system calls to the specific driver. Valid names are COM1:, COM2:, BCR1:, and so on.

To be easily identified, stream interface drivers follow a unique file naming convention, which is composed of a three-letter prefix (such as CAM for camera or BCR for bar code reader), a digit that identifies a specific device when multiple instances are available, and a colon. Consequently, stream interface drivers have been designed to expose a device's capabilities to the applications by presenting the device as a special file, which can be opened, read from, written, closed, and so on. Microsoft chose to re-use an existing API (specifically, the file API) to enable the applications to access those drivers, instead of creating a new one. For instance, upon connecting a GPS device to the platform, the user will start a GPS-enabled application that will access and use the device. Stream interface drivers that control installable devices are typically accessed by applications.

They are mostly used for controlling installable devices (a scanner, for example), but a few are used with built-in devices, such as the serial port device driver, because the stream interface is better suited for those devices. Stream interface drivers all share a common interface. Native drivers are always loaded at boot time. Native drivers are built as dynamic-link libraries, with two exceptions: the battery and the LED drivers are built as static libraries (linked with the GWES module when a CE image is built) because of their small size. Suffice it to say at this point that none of these interfaces can be changed by OEMs and that native drivers must fully support them. These interfaces are explained in more detail later. Hence, each native driver must conform to a specific, well-defined interface called the device driver interface (DDI). As one might expect, these functions are different from those required in the battery driver. For example, the graphics, windowing, and events subsystem (GWES) module calls specific functions in the display device driver to render images at runtime. These devices are controlled by native drivers, which are intimately linked to Windows CE's core components. Windows CE has been designed to directly use built-in devices. Furthermore, CE drivers are implemented as either static libraries (.lib files) or dynamic-link libraries (.dll files). It is important to mention that this driver model is unique to CE Windows 9x/NT/2000 drivers are not supported. Each type is described in the following paragraphs. Windows CE supports four driver types: native, stream interface, USB, and NDIS. Those drivers can be installed at any time (in the object store, which is non-volatile RAM, for instance). Third-party vendors (who manufacture the installable devices) provide the device drivers. For instance, a bar code reader can be connected to a Windows CE device by means of a cable that connects to the built-in serial port. Installable devices are third-party peripherals that can be connected and detached from the platform at any time by the end user. The development of the related drivers takes place during the development of the platform itself (by the OEM), and the drivers are integrated into the final CE image, which is stored in ROM or flash.

Devices that fall in this category include the display, touch panel, audio, serial port, printer, keyboard, LED, battery, and PC card socket. This article presents Windows CE's device driver model, which is unique throughout the Windows family.īefore exploring the details of the device drivers supported by Windows CE, let's review the two types of devices that are used on Windows CE platforms: built-in devices and installable devices.īuilt-in describes those devices that are integrated into the platform. Microsoft Windows CE is a modular and scalable operating system that supports a variety of devices. Here's a quick tour of the Windows CE rulebook. Every operating system places requirements on device drivers.
