ZZ from http://blog.csdn.net/fudan_abc/archive/2007/06/23/1662739.aspx 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. CC Not much said, with the driving life of the Apple Driver pack to solve the problem of Apple Computer after the Windows7 drive is very simple, as simple as installing a

Windows Driver Development Foundation, reprint marked Source: http://blog.csdn.net/ikerpeng/article/details/38793995Let's talk about how to compile the driver after it's developed. 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

Windows cannot verify the digital signature of the driver required for this device. A software or hardware has recently changed and may have a signed or damaged file installed, or the file may be an unsolicited malicious software. (Code 52)Recently replaced a new motherboard, upgraded WINDOWS10 RS2 (14955)The good news is that Windows 10 is now like an apple, capable of supporting the coreaudio of those sound cards, and is free-drive.The bad news is t

Fault symptom:When the Driver and Application Installation are used on the Y710 Cube to overwrite the Driver for installing the Killer NIC and Wireless NIC, or the Driver is upgraded and installed, the DAI software cannot be installed.Cause analysis:The Silent installation parameters of Killer NICs and wireless Nic drivers are only applicable to all-new installat

During the summer vacation, I made a project using SSH + mysql5.0 + atat5.5.After deployment to the server (Tomcat is 6.0.32), the test runs normally. The next day, I found that I could not log on. I checked the system and found no problems. I restarted Tomcat and recovered to normal again.Very strange, so I checked Tomcat logs and found the following problems: 2011-9-1 0:15:11 org. Apache.

This article is written in November 13, this is only a record of the knowledge that has been covered in this area, may be useful for some knowledge of the futureFor the platform bus model, you can refer to a previous article on the Linux driver platform bus model, which may be helpful for framebuffer driver registrationFirst, the LCD hardware frameworkSecond, LCD software frameworkThird, LCD initialization

From this blog post, we can finally give our driver module First_drv a formal compilation, now he has filled out his account registration information form, from the account of the child only one step!Inside the kernel has its own set of methods to install the driver module, like the Civil Affairs Bureau staff know how to run an account for a person, for an ordinary citizen, the staff did what the operation

keyboard interruption is 1 ). The keyboard interrupt service routine provided by the keyboard driver is executed due to keyboard interruption. In the keyboard interrupt service routine, the driver reads data from i8042. OnceAfter the data is read, bit0 of the Status Register is cleared. To read data, first read the Status Register and Judge bit0. The Status Register bit0 is 1, indicating that there is data
