A quick search in the Web reveals that the number of the books that are related to Windows Device drivers can be counted with the fingers of one hand. even worse, most of the books are either too old (published before or around Windows 2000) and/or not easilyReadable. Another problem is that the
time. Windows allows windows-based applications to multitask by using a VxD. A VxD handles interrupts in connection with Windows and performs I/O operations for applications that require I/O operations and does not affect the execution of other applications. Most VXD management hardware devices, there are also some VxD to manage or replace related software, such

The stream device driver is actually the driver for exporting standard stream interface functions. This is the definition above. In wince, all stream devices export stream device interfaces, so that Device Manager in wince can load and manage these stream device drivers.

Once upon a while, we found a job as a driver engineer, with a low monthly salary. The Code of people we have never touched cannot be understood at all.
Today is good. If we do not want to pursue differentiation, we can allow the system to communicate with USB devices without drivers. Linux will not talk about it. libusb is very useful. Now we will talk about windows.
Winusb is a ki

Copy all files in the "Development Kit" to the "bin" directory of the project, or a dedicated generated directory under the project. The Development Kit files include:
/proc/devices | awk "}"
To get the main device number, you can add the command line above to your shell script.
Minor is from the device number, set to 0 on it.
We can now access our drivers through the device files. Write a small test program.

I do not know the USB audio device class before developing the driver for the USB audio device. I thought it was a hid driver and it should be easy to develop, later, I found myself in an unknown field. Thanks to the previous development of the mass storage firmware program and the knowledge of the ov511 USB camera driver, the development was completed even though it took more time and twists and turns in t
environment passed to the hot-plug handler includes a firmware variable, which is set to the name provided to Request_firmware
The handler locates the firmware file, copies the firmware file to the kernel using the provided properties, and if the firmware file cannot be found, the handler sets the loading property to-1
If a firmware request cannot be serviced within 10 seconds, the kernel discards the effort and returns an error state
The sample device drivers encoded with the Windows CE platform builder come in two forms: Monolithic And Layered . Source code for a monolithic driver consists of both interrupt service thread code and platform specific code. in contrast, layered device drivers split the cod
Because Windows shields the underlying system operations, the system becomes safer for users, but it brings great difficulties to many hardware or system software developers, as long as the application involves underlying operations, developers have to go deep into the Windows kernel to write system-level virtual device drive
, command buffers, custom parameters, and real-time data elements.(4) The framework platform supports scheduling according to the priority level of the device command, ensuring that high-level commands are sent in a timely manner.(5) A device driver supports both serial and network communication methods, can monitor IO channel data.(6) A device driver that can su
licenses accepted by the kernel include "GPL", "GPL v2", "GPL and additional rights", "Dual BSD/GPL ", "Dual MPL/GPL", "Proprietary ".In a device driver that supports both the 2.4 and 2.6 kernels, the module can declare its own license as follows.

The result of this RTC universal layer implementation is that the underlying RTC driver no longer needs to care about the specific implementation of RTC as the character device driver, and does not need to care about some general RTC control logic, figure 3 shows the relationship.
