★ General IntroductionLED driver mainly realizes the hardware drive of 4 LED lights on the TQ2440 Development Board, realizes the Pin GPIOB5, GPIOB6, GPIOB7, The high and low level setting of the GPIOB8 (the configuration of the PIN is already implemented in the COMMON-SMDK.C), the driver is called with the test program, and the LED light is illuminated by comman

During this time, I have been working on Android drivers. The underlying Android driver is exactly the same as that of Linux. So I am going to make a special topic here. I will summarize the Linux driver and lay a solid foundation for the next driver

Android system transplantation and driver development-Chapter 5-Build a test environment for the Development Board and android-based development The embedded system installed on the Development Board is much simpler than that on the mobile phone, and there are many extended

Last year, the development of an OA system, need to implement a key document upload and realize online preview, similar to the function of Baidu Library. System Environment: CentOs5.5Tools used: Openoffice 3, pdf2swf tool, Jodconverter, Flexpaper On the Internet to find some information, someone has already realized such a function, but it is written in Java, PHP did not find.Combined with the data on the Internet to achieve operational experience.Rec

When compiling the scull program of ldd3, the compilation fails, and the problems encountered are the same as those encountered by the following buddies, Follow the steps below to solve the problem and record it here. /*************************************** **************************************** **************************************** ********************/ Recently, I was reading the character device driver scull in

Linux Driver Tutorials : Http://pan.baidu.com/s/1c0hljUSWrite a simple application call driver--header file? Print header File–include ? The header file needed to invoke the file in the app– #include The environment is maintained as a 32-bit value and grows to a 64-bit value in the 64 compilation environment.– #include Tao, socket, character, block properties– #i

In the first stage, I learned to familiarize myself with Linux on a PC. common Operations under RedHatLinux9 II. use of Minicom 3. NFS usage 4. application Programming Experiment 5. module programming Experiment 6. the second stage of the simple character device driver experiment is to study Linux 1 on the Development

use of the Linux kernel header files. In order to test the driver on Ubuntu Linux, you need to specify the directory (/usr/src/linux-headers-3.0.0-15-generic) of the Linux kernel header file using the-C command-line parameter. Where the

The biggest feature of Linux devices is that device operations are like file operations. In the application layer, a hardware device is just a device file. Applications can operate hardware devices like operating files, such as open (), close (), read (), and write. Below is a simple implementation of the character device driver test. c # Include Module Analysis 1. initialize the device

This article uses the source code in the book "android Deep Exploration (Volume 1): Hal and driver development" as an example to describe how to configure the android driver development and test environment, and how to use build in the source code. the sh script file is used to compile, install, and test the

the unfamiliar driver development of the programmer to use.But it is a pity that the old WINUSB does not support synchronous transmission, and the system above win8.1 starts to support synchronous transmission.If you really use winsub, you can now use a large number of WIN7,WINXP users.There is also open source Libusb, this project is good, he is mainly active in the L
