Author: wogoyixikexie @ gliet Previously, I heard from my friends about porting drivers under PB to BSP, and even the file system to BSP. -- Haha, It's very advanced. Now I will take the SD card of 2410 as an example. Previously I did not know that the SD card driver would be in the Pb installation file. Let's take a look at the following three posts-2410 large-capacity SD card research. Http://topic.csdn.net/u/20080911/16/111a849c-fd1f-4955-840d-6ddf

OCI: to install the Oracle client, the portability is slightly poor, and theoretically the performance is better Thin: belongs to type4, which is implemented in pure Java and has good portability. Theoretically, the performance is slightly lower. Recommendation: it is best to use thin driver, which is more portable and more standard, with fewer problems. As for the performance, to be honest, thin driver

Android, X Windows, QT, and many other applications support input devices, such as the keyboard, mouse, and touch screen, in Linux systems, or increasingly prefer the standard input subsystem. Because the input subsystem has completed the character-driven file operation interface, the core task of writing the driver is to complete the interface set aside by the input system, with little workload. But if you want to apply it more flexibly, You need to

Character Device Driver: 1. Generally, we use APIs that dynamically allocate device numbers: Int alloc_chrdev_region (dev_t * Dev, unsigned int firstminor, unsigned int count, char * Name ); Dev is a function used for output. After successful call, the first number of the allocated range will be saved. Void unregister_chrdev_region (dev_t first, unsigned int count ); The above function allocates device numbers for

Laptop installed sound card driver error no appropriate Driver to be installed Cause Analysis: There are Realtek and conexant two kinds of sound cards, when the system can not automatically identify the device when there will be an error. Solution: Enter the corresponding folder double-click Setup to install the driver If Realtek's sound card enters the

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

Part of this article refers to the blog from Droidphone (http://blog.csdn.net/droidphone/article/details/6271122), about Alsa writing a very good article, just a few examples. This article is a combination of examples to analyze the ALSA audio driver.Development environment: ubuntu10.04Target board: linux-2.6.37 (view Linux kernel information via command uname-r)Compiler: arm-none-linux-gnueabi-(None on behalf of compiler creator, such as: FSL for Freescale, the kernel to talk about Eabi,oabi, i

Access to the character device is performed through the device name in the file system. Those device names are simply nodes that are called file system trees, and they are typically located in the/dev directory. Device files for character device drivers can be identified by ' C ' in the first column of the ls-l command output. Block devices are also located in/dev, identified by the character ' B 'CRW-RW----1 root root 253, 0 2013-09-11 20:33 Usbmon0CRW-RW----1 root root 253, 1 2013-09-11 20:33

Linux under the I2C-driven loading process, divided into I2C equipment layer, I2C adapter layer and I2C core layer The I2C device driver layer is the drive we write for a particular I2C device, and the following is the I2C-driven registration process I understand. In the I2C device driver we write, we call I2c_add_driver () to start I2C device-driven registration, which calls I2c_register_driver Complete a

Install the NVIDIA GTX750 graphics card driver in Ubuntu 12.04 I recently installed Ubuntu 12.04 on my computer. After I started it, I found that the system only has 1024*768 resolution. My computer's independent graphics card is Nvidia GTX 750, and the display supports 1920*1080. The method of adding resolution to the system for online searching is useless. Later, I downloaded the Linux driver from the NVI

Problem: After installing the new 5.1 mysql odbc Driver, the program prompts "(MySQL ODBC 5.1 Driver). The specified Driver cannot be loaded ." Solution: The security settings of windows2003 are very important. Therefore, many people set the directory permissions only for the Administrator and SYSTEM, but such settings may cause problems in running My SQL. Th

Recently, I 've been reading "programming for Windows Kernel fishing in Hanjiang". I 've seen the keyboard filter section and noted down the notes for your reference only. I hope you can correct me if you understand something wrong. Now, for traditional keyboard filtering, You can bind your device object to a kbdclass device object. The IRP sent to the kbdclass will first pass through the device object. We can set the completion routine in the dispatch letter number. After the IRP is completed,
