Windows driver development and windows driver development The previous article "Windows driver development-basics 2" has introduced the windows framework. What are the differences between WDF? We know that in WDF, KMDF is required. KMDF is based on WDM. WDM Driver Model In the WDM

Install Nvidia graphics card driver in Linux: Disable The Nouveau kernel driver. Method System: Red Hat Enterprise 6 (32-bit) video card: after downloading the driver from the Nvidia official website, Nvidia Gforce 7300GT directly runs the installation in text mode. The following error message is displayed: nvidia-installer log file '/var/log/nvidia-installer.log

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

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

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

In the previous blog post, we have compiled the First_drv.ko file by makefile, which is a driver module that can be installed in Ubuntu.Execution in/work/my_drivers/first_drv/1th/directory: Insmod First_drv.koIf you are executing this command in a normal user state, you can see that the system reminds us: insmod:error inserting ' First_drv.ko ':-1 operation not permittedThis is because installing the driver
