The previous article introduced the concept of Linux drive, and the basic classification of device drivers under Linux and the basis and difference of each classification, this article describes how to write a simple test driver like Hello World. and the only function of this driver is to output Hello world.Before writing a specific instance, let's take a look at an important function of the debug program u

We often delete the computer does not use software, the network card driver accidentally deleted. Delete the network card driver can not be downloaded on the Internet drive but your computer does not have a backup drive, there is no system disk, can not restore the system, now how to restore the network card driver? 1 If you are manually uninstalling the NIC

After installing the system does not have the network card to drive cannot connect the net, then how installs the network card to drive? The following small series for everyone to bring Win7 network card driver installation method Introduction, have the need of friends to go to see it. Win7 Network card driver installation method: 　　Method One: Directly with the motherboard drive CD installation. Put the

Various printer installation Tutorials: To install a local printer 1, recognize the printer model, find the printer's drive CD-ROM or download the printer driver from the official website. HP2288, for example, downloads printer drivers from HP's official website, or drives life with a universal drive downloader to download printer drivers 2, double-click the driver to install, after installation after th

Linux driver development-I/O memory access process, driver development-I A device usually provides a set of registers to control the device, read/write devices, and obtain the device status, including the control registers, data registers, and status registers, which may be in the I/O space, it may also be in the memory space. When it is in the I/O space, it is usually called the I/O port. When it is in the

★ General IntroductionLED driver mainly realizes the hardware drive of 4 LED lights on the TQ2440 Development Board, realizes the Pin GPIOB5, GPIOB6, GPIOB7, The high and low level setting of the GPIOB8 (the configuration of the PIN is already implemented in the COMMON-SMDK.C), the driver is called with the test program, and the LED light is illuminated by command.★ Detailed INTRODUCTION 1,

At present, a small number of users reflect the updated graphics driver, restart the computer, the screen resolution is very low, color quality is poor, and resolution can not be adjusted and so on (XP system). (veterans, please ignore them directly, novice small white seriously look at the reason: update the graphics driver, the updated driver file is not proper

Preface Device tree is a data structure used to describe hardware, similar to a plate-level description language, originating from OpenFirmware (of). In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation needs. But the plethora of platforms, the different hardware that led to

The following are my notes from jollen (non-teaching documents), which cannot be clearly explained in many places. Please complete this part on your own. This article is a reference for anyone who wants to study the implementation of the Linux MMC driver (MMC core. Based on Linux 2.6.17.7, the kernel of the updated version is added with many patches (for example, sdhc patches of Linux 2.6.19). These updates

The BS System Using C # + ODBC has no problem in vs2005, but it will appear after it is released"Error [im002] [Microsoft] [ODBC driverProgramManager] No data source name found and default driver not specified"Error, the problem is that the type created by DSN is incorrect. In "ODBC data source Manager", you can set three DSN types for connecting to the database: User DSN, system DSN, and file DSN. IIS is a system-level NT Service. Therefore, you ca

I. Some preliminary knowledge 1. You have been able to write led bare-board drivers.Program 2. convert a physical address to a virtual address In the program, we can only use the converted virtual base address and register offset to access the corresponding register, instead of directly accessing the physical register as the bare board program, so the physical address must be converted, the following is an example. # Include Void _ iomem * vir_base; vir_base = ioremap (gpio_base, gp

To reinstall ODBC, follow these steps: Use odbcconf.exe to re-register the ODBC driver. There are several script files in the Windows/system32 directory to complete the driverProgramRegistration: Odbcconf.exe/S/LV odbcconf. log/F % SystemRoot % \ system32 \ mdaccore. RSPOdbcconf.exe/S/LV odbcconf. log/F % SystemRoot % \ system32 \ sqlclnt. RSPOdbcconf.exe/S/LV odbcconf. log/F % SystemRoot % \ system32 \ odbcconf. RSPOdbcconf.exe/S/LV odbcconf. log/

At the end of the norflash driver load, there are several statements: If (ezkit561_mtd) {ezkit561_mtd-> owner = this_module; return handler (ezkit561_mtd, ezkit561_parts, ezkit561_part_count );} use add_mtd_partitions (Drivers/MTD/mtdpart. c) The function can add corresponding partitions to the partition table of the system. In this way, when you need to read and write the partitions, you can find the corresponding MTD and call its function to complet

It took almost a week to learn drivers. During this period, I was busy learning Linux application programming, search driver, and kernel-related books for further study. In the previously friendly driver routines, the knowledge involved is very limited. It is imperative to study more driver source code and learn more about dr
