Summary previous we analyzed a virtual hardware network driver sample. From here we see some of the interfaces of the network devices. In fact, the function of network device driver and block device driver is similar, both sending and receiving packets (data request).Of course they are actually very different.1. IntroductionFirst, the block device has a device no

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. What is the 6.1Linux drive?Linuxthe way the driver works and how it is accessed isLinuxone o

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

Driving life may be driven by the installation of an Apple phone, we just drive the life on the computer, and then turn on our click "Update Now" button to update, this drive life can help us install the latest driver. Click to open the peripheral driver interface, you can see that the computer all external access to the USB input device, will appear in this interface. Click on a device, you can view t

Obtain the database connection through Driver and the driver database connection Take a look at the file. There is a properties configuration file under the current package, and there is a lib folder under the root directory, which contains the mySql driver jar package Driver: an interface. The database vendor must pr

Linux Device Driver Article 4: Driver debugging methods, linux Article 4 In the previous article, we probably talked about how to write a simple character device driver. We are not a god, but there will certainly be a problem when writing code. We need to continuously debug it during the code writing process. In common c applications, we often use printf to outpu

Continue to drive learning based on the progress of the previous article ....... Main references: http://blog.csdn.net/dg1683wen/article/details/6861044 First, build the kernel source code tree.

If the system needs to be re-installed in case of a computer failure, if the random drive disk is lost, such as the motherboard driver, NIC driver, and graphics card driver. In particular, some old machines, motherboard integrated Nic, graphics card. Even if Win2000/WINXP is installed, some devices cannot be automatically driven. In this case, we can consider u
