The installation of the front toaster driver is installed by manual installation, the Sys/inf and other files to the system. To be honest, this is a complicated process, except the developer, the other people can smooth installation of the driver is really impossible. If the reader has bought computer accessories in Computer city, such as wireless card, Bluetooth adapter, should have the impression: hand in
In the previous blog post, we have learned how to coordinate how each level in the whole system works, and the command issued by the application layer reaches the drive layer under the kernel, thus achieving the purpose of operating the hardware layer.Let's look at the code in the final molded "shell driver" first_drv.c in the last blog post:#include As I said in my previous blog post, there is a disadvantage to this
The relationship between device and driver in linux driver development-Linux general technology-Linux programming and kernel information. The following is a detailed description. Yesterday I saw a piece of news titled "Housewives use LINUX". If we saw this news 10 years ago, we would be surprised to say, "I rely on it, housewives also use LINUX ", but now housewives use LINUX is not new to us because LINUX
Hyper-V Virtual Machine installation and nic cannot be found, driver cannot be installed Solution
I recently used a virtual machine in win2008 and encountered some problems during use. Now I have recorded the installation process and handling methods.
1. Install hyper-V. Right-click my computer and choose manage → Server Manager → role → add role on the right → select hyper-V for Installation
2. Choose "start"> "Management Tools"> "hyper-V ".

Before analyzing the driver, we will analyze the model of the IIC subsystem. There are 2 ways to IIC device drivers, one of which is to write user-driven through a universal driver. The other is to add a IIC device driver directly to the IIC subsystem, such as a driver for AT24C02.
Next we'll learn how to write a I

When we get a BSP, if we want to do or transplant the driver of the buzzer, first determine the next coreThere is no buzzer driver, we can use Sourceinsight to put the kernel in, search buzzer this file, see if

Adding a driver to the android kernel is actually adding a driver to the Linux kernel. It mainly adds vertex information to two files, one is the kconfig file and the other is the MAKEFILE file. For example, if the driver you added is placed in the xxx directory under the DRIVERS directory, the kconfig and makefile files under the directory will be repaired.

between the device and the drive, through the platform bus, the device and the driver is separate registration, through the platform bus probe to detect and match the device at any time, such as matching on the device driver registration;C: Due to the above advantages, a driver can be used for several similar devices;3:platform Bus and platform bus device

Framebuffer is a display device inside Linux. How to operate the LCD at the bottom of the drive to achieve graphical display.1. What is Framebuffer?(1) First consider how we operate the LCD in bare metal.The SOC has an LCD controller, an LCD driver outside the SOC, an LCD driver connected to the LCD screen, a CPU inside the SOC, and an external DDR memory. These devices are all part of the LCD display.What
first, the Linux system divides the device into 3 categories: Character device, block device, network device. 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 and led device.2, block device : Refers to the device can be read from any l
