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

1. Driver test of onboard buzzerI have a BSP, jiuding BSP, which has a buzzer driver, we first test it well. 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

In the Linux device driver first: Introduction to the device driver briefly describes the character driver, this article briefly describes how to write a simple character device driver. This article draws on the source code in the LDD, realizes a hardware device-independent character 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

The technology used is basically the same as that used in the application layer, but the problem of mutual exclusion has interfered with me for a long time. Fastmutex is used, but it will upgrade IRQL to apc_level. Obviously, all the file-writing service functions can only run under passive_level, so the event is used. Sample Code Description: For details about getcurrenttimestring (), refer to the previous section:Get the current system time in the W

This time I will study the Code with the I2C driver in the kernel. Before going into the code, I will first briefly understand the relationship between the I2C core data structure. From this, we may be able to have a better understanding of the driver code. The design of the software data structure and the relationship between the data structures should at least describe the Organizational Relationship of t

USB urb (USB request block) Kernel 2.6.29.4The USB device driver code communicates with all USB devices through urb. Urb uses the struct urb structure description (include/Linux/USB. h ). Urb sends or receives data asynchronously from a specific endpoint of the same USB device. A USB device driver can allocate multiple URBS to one endpoint or reuse a single urb to multiple different endpoints Based on the d
