A few days ago, the system was re-installed with the Windows7 RC system. Yesterday began to try to put on the Wireshark this very powerful network monitoring software, filled with joy to open, but each open will pop up "the NPF driver not running ..." Error Prompt window. Last night was a night of trouble. Baidu and Google have said to open NPF driver, and then I
1. Device Driver. In the Linux device model, the device driver is represented by the device_driver structure.

Abstract:For the PC104 SCM/deth dual-port ethernet card, an intelligent dual-redundancy Network Driver Based on the Vxworks system is designed, the driver provides functions such as network communication fault diagnosis and intelligent switching between NICs. By testing the performance of the smart dual-redundancy

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
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

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
This chapter is a concrete example of the complete process of developing and testing a Linux driver. Especially test Linux drivers. In this example of counting the number of words, the emphasis is on the implementation of the algorithm: the Linux driver, not how to count.

Basic Principles
Through framebuffer, the application uses MMAP to map the video memory to the virtual address space of the application. The data to be displayed can be displayed on the screen after being written to the memory space;
The driver allocates system memory as the memory for display; implements interfaces in the file_operations structure to serve the application; implements interfaces in the fb_ops structure to control and operate the LD
Through the first article, we already know that the whole SPI drive architecture can be divided into three parts: Protocol driver, general interface layer and controller driver. The controller driver is responsible for the data sending and receiving work at the lowest level, in order to complete the data sending and receiving work, the controller
