I have been learning device-driven programming for some time and have written several drivers. So I have a new understanding and understanding of the device driver. I have been learning device-driven programming for some time and have written several drivers. So I have a new

Brief introduction The name of the TTY device is abbreviated from the previous telex, originally referred to as a physical or virtual terminal connected to a UNIX system The core of the Linux TTY driver is immediately below the standard character device driver layer and provides a range of functions that are used as interfaces by terminal type devices There are three types of TTY

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 drivers. WIN98 and Win95 device

1. Get the kernel version When the device driver needs to support different kernel versions at the same time, in the compilation phase, the kernel module needs to know the version of the currently used kernel source code to use the corresponding kernel API. In the 2.4 and 2.6 kernels, the source code header file Linux/version. H is defined as follows: Linux_version_code: the binary representation of the kernel version. Each of the primary, slave, and

[E liangshi Yiyou network] in the UNIX operating system, access to I/O devices is performed through a set of fixed entry points, this set of entry points are provided by the device drivers for each device. Generally, the drivers of devices provide the following entry points: 1. Open entry point. Open the

Excerpt from: http://blog.chinaunix.net/uid-20799298-id-99675.htmlThe original text is writing device driver in linux:a Brief tutorial.This article focuses on three examples to explain the Linux driver, so that novice quickly, from the code layer to understand what is the Linux device driver.This article is a note, in general translation of the first two parts of the article, namely the first two examples,

, USB audio class device, USB video class device, and mass storage devices can be used to develop general device drivers. You only need to modify the vid and PID.(2) In addition to implementing the stream Driver Interface for a USB device, you also need to implement the thre
