★ 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 command.★ Detailed INTRODUCTION 1,

At present, a small number of users reflect the updated graphics driver, restart the computer, the screen resolution is very low, color quality is poor, and resolution can not be adjusted and so on (XP system). (veterans, please ignore them directly, novice small white seriously look at the reason: update the graphics driver, the updated driver file is not proper

Preface Device tree is a data structure used to describe hardware, similar to a plate-level description language, originating from OpenFirmware (of). In the current widely used Linux kernel 2.6.x version, for different platforms, different hardware, there is often a large number of different, poor portability of the board level Description code to achieve these different platforms and different hardware special adaptation needs. But the plethora of platforms, the different hardware that led to

We open "Drive Wizard" software in the computer, the effect is as follows In the Open interface we just click on the second "driver" below Then you will automatically get all the drivers you want to upgrade. We click on "Upgrade" to start downloading the driver files. The driver will be installed automatically when the download is complete.

2.1 Main Program Interface The Driver Wizard version 2009 includes full drive installation, hardware information detection, and common tools download features that you can use to find shortcuts to these features in the main interface of the Driver wizard. The function of the driver area is "Update Driver"

It took almost a week to learn drivers. During this period, I was busy learning Linux application programming, search driver, and kernel-related books for further study. In the previously friendly driver routines, the knowledge involved is very limited. It is imperative to study more driver source code and learn more about dr
