Using drivers:1, character device : Refers to a byte can only one byte read and write devices, can not randomly read the device memory of a certain data, read data need to follow the data. The character device is a stream-oriented device, and the common character devices are mouse, keyboard, serial port, console a
Article title: describes the driver framework and driver loading in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
This section describes the Linux device driver framework, driver

B)You can either directly send a keyboard, mouse, or other message to the game process by determining that obstacles, monsters, and other things on the map have crossed the map. Of course, killing monsters is done by simulating buttons.
However, with the destructive impact of plug-ins on the game, anti-plug-ins and plug-ins have been entangled in the kernel layer, such:

The wince application was started two years ago. However, due to division of labor, there has never been a chance to gain a deep understanding of the development of the wince Driver (including Pb-related system customization ). If it weren't for the fakegps development work that was scheduled by Ma Ning some time ago, I really don't know when to understand the wince driver development.
Fakegps is a disguise
In the previous article, we introduced the framework of the character device driver. In this article, we will operate on the real hardware-led.

Access to the character device is performed through the device name in the file system. Those device names are simply nodes that are called file system trees, and they are typically located in the/dev directory. Device files for character device drivers can be identified by ' C ' in the first column of the ls-l command output. Block devices are also located in/dev, identified by the character ' B 'CRW-RW----1 root root 253, 0 2013-09-11 20:33 Usbmon0CRW-RW----1 root root 253, 1 2013-09-11 20:33

Linux under the I2C-driven loading process, divided into I2C equipment layer, I2C adapter layer and I2C core layer
The I2C device driver layer is the drive we write for a particular I2C device, and the following is the I2C-driven registration process I understand.
In the I2C device driver we write, we call I2c_add_driver () to start I2C device-driven registration, which calls
I2c_register_driver Complete a
This section describes the Linux Device Driver framework, driver configuration files, and common methods for loading drivers. It also describes how Red Hat Linux installer loads drivers, we can put the driver into the boot disk by ourselves; after installing the system, we can use kudzu to automatically configure the hardware program.
Linux Device
1. Device Driver. In the Linux device model, the device driver is represented by the device_driver structure.
Struct device_driver {const char * Name;/* name */struct bus_type * bus;/* attached bus */struct module * owner; const struct of_device_id * of_match_table; INT (* probe) (struct device * Dev);/* call */INT (* remove) (struct device * Dev) when the device matches the
You know, drive life. Network card version of the new Realtek network card driver win10 version? Often heard that a small partner said that after the installation of the WIN10 system, the computer can not network. Even in the use of Driver Life Card version to install the network card driver is still unable to solve the problem.
Because the WIN10 system can use
2.1Network Driver StructureThe architecture 1 of the Linux Network Driver is shown in.It can be divided into four layers:(1) Protocol Interface Layer
(2) network device interface layer
(3) Device Driver Function Layer
(4) network device and media layer.

By the way, record this blog: the Linux USB driver development of Mingyue may be available in the future.
The three important concepts of the Linux device model are bus, device, and driver. that is, bus, device, driver. In fact, the kernel also defines such data structures. They are str
How to use the platform device driver to write the driver:-------------------------------------------------------------------------1. Implement device orientation first:1) read the chip manual and obtain resources from the schematic diagram.2) construct a platform device structure and add platform Resources3) link our device resources to the device connection table of the virtual bus.
2. then implement the
Whether you're a MacBook Air or a MacBook Pro, or an imac-all-in-one series, with an Apple computer for a Windows-series system such as Windows7, the download-driven Apple driver Pack can solve all the drive problems with a single click.

Generally there are several ways to do this:1. Create makefile file, compile and link with NMAKE tool;2. Build makefile,sources, dirs file, compile with build tool.3. Compile the link with the integrated development environment.I
