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

First on the computer to download 360 mobile phone Assistant "Click this Download", and then according to 360 mobile phone assistant prompts operation can Note: If USB is not turned on in your phone, we need to turn on the 4 USB debugging (Recommended reading: Millet 4usb Debug Mode open method) and then the mobile phone and computer connection when the computer's 360 assistant will automatically install the mobile phone

[Open-source] Easy 4-step QQ login, no need for any code skills [no language boundaries], 4-step skills It is said that on the 17th, a simple tutorial was issued on the 17th, and this was encapsulated after the qq verification was passed. Now it is released ~~ This is an open source project I encapsulated: https://github.com/dunitian/LoTQQLogin ------------------

?? Figure 9 String Array in Internet Explorer ?? The reader class has a special method for explaining BASE64 and BinHex encoded streams. The following code snippet demonstrates how to parse a document created with the BASE64 and BinHex encoding sets using the ReadBase64 method of the XmlTextReader class. XmlTextReader reader = new XmlTextReader (filename); while (reader. Read ()) { if (reader. LocalName = = ' element ') { byte[] bytes = new byte[1000]; int n = reader. ReadBase64 (byt

Today, we will go to Chapter 6 advanced character driver operations in Linux Device Drivers (version 3rd. I. IOCTL In addition to reading and writing capabilities, most devices can perform operations beyond simple data transmission. Therefore, device drivers must also be able to perform various hardware control operations. these operations are often supported by the ioctl method, which has a prototype different from the user space version: int (*ioc

", 0x50) . Platform_data = AT24C08, } ;Because there may be multiple I2C devices, keep them in an array. Then use the I2c_register_board_info function to register the array of our defined I2C devices into the Linux kernel: I2c_register_board_info (0, Mini2440_i2c_devices, array_size (mini2440_i2_devices)); So where to register this I2C device. Typically in the system initialization of the Development Board, the corresponding mini2440 is registered in the Mini2440_machine_init fu

MEF is easy to get started with, but it strives to be easy to understand (4 ). In the previous article, we can obtain various FileHandler instances and corresponding metadata. In this article, we create a slightly complete file manager. 1. Modify the IFileHandler interface and input the file name. namespace IPart{ public interface IFileHandler { void

Four. DM9000 Network card driver Depth analysis1. Initialization of the DM9000Dm9000_init (){1. Assigning Net_device Structures2. Get the address break number from the Platform_device3. Map the acquired address to the virtual address operation function Io_remp ()4. Read the chip type5. Set the number of operating functions6. Register the network card driver regis

4 bus driver 4.1 Overview The I2C bus driver is a software implementation of the I2C Adapter. It provides the ability to complete data communication between the I2C adapter and the slave device, such as the start, stop, response signal, and master_xfer implementation functions. The I2C bus driver is described by i2c_ad

the form of the wince device. Then, the upper layer of the controller is the Client layer, which is commonly used in three categories: Mass Storage, rndis, and serial. When the wince device needs to behave in what form, it is converted by the Controller Driver (unmount the old client and load the new client ). The device is called function, so the full names are USB function controller driver and USB funct

First of all, the implementation of the LED driver principle, the Linux driver is not directly to the memory of the hardware to write data, but with the native I/O memory interaction, each of the hardware connected to Linux in I/O memory will have a map of the first address.To write the driver, first create the LED-driven device file:1. Initialize the Cdev with t

Windows File System filter driver development tutorial 4. device stack, filtering, file system awareness The front side is introducing the structure of the file system driver, but we haven't talked about how our filter driver can capture all the IRPs sent to the file system dri
