What are the driver development techniques? 10

Step 2: According to the landlord, it is dark, then this disc should be self-running, it may be that the file called is unavailable or some other reason. If the first step is normal, run the auto-run program on your hard drive, usually with the file name or If your computer is set to hide known file extensions, the "." after the file name will not be displayed

exe", after normal operation, follow the prompts step by step.

Step 3: If the first two steps cannot be performed correctly, you need to install the driver manually, this process can refer to the manual when you purchased the computer, if there is no relevant manual for this process, please refer to step 4.

Note: If you want to install the driver manually, you can find the folder corresponding to the hardware under the disc file and run the installer inside. If you don't have the program installed, please find the device with the question mark in "My Computer --> Properties--> Hardware (Win2000 and above system '-Device Manager')", then right-click on the question mark --> update the driver, and then follow the prompts step by step.

I'll go there, and I'll answer the question upstairs.

The full name of the driver is the device driver, so how to uninstall the driver, let's introduce it to you.

1. First, double-click to open "This Computer", click "Computer", and click "Manage".

2. Then click "Device Manager".

3. Then click the drop-down symbol on the left side of "Display Adapter".

4. Finally, right-click on the uninstalled driver and select "Uninstall the device".

Driver, a computer software term, refers to a program that drives software in a computer. A driver, which stands for Device Driver, is a special program added to the operating system that contains information about the hardware device. This information enables the computer to communicate with the appropriate device.

A driver is a configuration file written by a hardware manufacturer based on the operating system, and it can be said that without the driver, the hardware in the computer cannot work.

Steps? There are no ready-made steps that can be used as a rule.

There are two basic requirements for development drivers:

a. Understand how the hardware at hand works, including knowledge of the processor architecture, and the datasheet of the peripheral controller is a must-read;

b, if the whole system you want to develop is a bare-metal program, then the driver you want to develop is a set of libraries that deal with hardware; But if you plan to use an operating system in your product, you need to be familiar with the internal workings of the operating system before developing the driver, because you are writing that the driver needs to be well "embedded" into the environment of the operating system.

Install DDK, write drivers, debug, test, package, and finish.

A driver, also known as a device driver, is a special program that enables computers and devices to communicate with each other.

Function: The main role of the driver is to complete the function of data transmission between the computer system and the hardware device, and only with the help of the driver, the two can communicate and complete specific functions. The driver is a medium between the operating system and the hardware, which realizes two-way communication, conveys the functions of the hardware device itself to the operating system, and also communicates the standard instructions of the operating system to the hardware device.

1. What is a driver?

Driver, English name "device driver", full name "device driver", is a special program that can make the computer and the device communicate, it can be said to be equivalent to the hardware interface, the operating system can only control the work of the hardware device through this interface, if the driver of a device is not installed correctly, it can not work normally. As a result, drivers are known as the "soul of hardware", "the master of hardware", and "the bridge between hardware and system".

For this reason, drivers play an important role in the system, and generally when the operating system is installed, the first thing is to install the drivers for the hardware device. However, in most cases, we don't need to install drivers for all hardware devices, such as hard disks, monitors, optical drives, keyboards, mice, etc., and graphics cards, sound cards, scanners, cameras, modems, etc. In addition, different versions of the operating system support hardware devices are also different, and in general, the higher the version, the more hardware devices are supported.

Second, the role of the driver.

With the rapid development of electronic technology, the performance of computer hardware is becoming more and more powerful. A driver is a piece of software that works directly on a variety of hardware devices, and its name "driver" also vividly indicates its function. It is through the driver that all kinds of hardware devices can operate normally and achieve the intended working effect.

If the hardware lacks the "driver" of the driver, then the very powerful hardware will not be able to work according to the instructions issued by the software, and the hardware will be useless and useless. At this time, the computer is just like the ancients said, "everything is ready, only the east wind is owed", and the role of this "east wind" falls on the driver. In this way, drivers really play a pivotal role in the use of computers.

Theoretically, all hardware devices need to have the corresponding drivers installed in order to work properly. However, devices such as CPU, memory, motherboard, floppy drive, keyboard, monitor, etc., do not need to install drivers to work normally, while graphics cards, sound cards, network cards, etc. must install drivers, otherwise they will not work normally. Why is that?

This was mainly due to the fact that these hardware were necessary for a personal computer, so early designers listed these hardware as hardware that could be directly supported by the BIOS. In other words, the above hardware can be directly supported by the BIOS and operating system after installation, and there is no longer a need to install drivers. In this sense, the BIOS is also a driver.

However, for other hardware, such as network cards, sound cards, graphics cards, etc., drivers must be installed, otherwise these hardware will not work properly.

Don't forget to install the driver after installing the system for novices, do you have to install the driver? What are you for?

What is a hardware device driver in the computer field? What is a hardware device driver file?

Do you know what a computer driver is? Without it, your computer software won't work!
