Often see someone on the Internet to ask the difference between LCD and LED display, small knitting is here a more comprehensive explanation of LCD and led differences in the end what is it? Manufacturers to promote the LED backlight energy-saving, environmental protection is a gimmick Mody? LED LCD difference is it re
1, start HD Tune program to detect hard disk
2, detect hard disk error;
Click: Error Scan-start;
Green small squares to indicate the hard part of the HDD, no bad, red squares indicate the hard drive damage has bad part of the road
3, is scanning the hard drive, the time is longer, waits patiently

Today according to the latest demand to the LED light flashing frequency changes, the default 2000ms to 10000ms, but after the change did not produce the expected effect, but into a constant, baffled its solution, and finally read the fucking code, from the top layer , all the way to chase down, finally found the problem, the following directly on the MTK led driver code:#define PMIC_PERIOD_NUM 9//* PERIOD,
The experiment in this chapter will realize the real Linux driver, which will realize the direct interaction with the hardware. 4 LED lights need to be controlled . the implementation principle of 7.1LED driveIn fact, it is not the Linux driver that writes data directly to the memory in the hardware, but interacts with the native I/O memory. I/o Memory is a mapping of hardware in host memory that is connected to the host through various interfaces.
LED Ceiling lampand theLED Tube LightThey are the indispensable lighting and decorations for the family decoration. They are both energy-saving and environmentally friendly while the light source color is more gentle, is to create household necessities. But becauseLED Ceiling lampwith theLED Tube LightThere are a lot of similarities on the outside, so many people may not be very clear about the two, do not know what the difference between the differen
Notebook HDD HDD user password Password How to clear? Notebook set the HDD user hard drive password, each power-on to enter a password, and can not be used as a mobile hard disk, "computer-management (G)--Disk Management" recognized, is also unable to initialize (data error, Cyclic redundancy check), even in the PE system, the hard disk can not be partitioned and
Today, we need to modify the flashing frequency of the LED light according to the latest requirements, and change the default 10000 ms to ms. However, after the modification, the result is not expected, but is changed to a constant, finally, I read the fucking code from the upper layer to the bottom layer, and finally found the problem. Next I directly wrote the MTK LED driver code:
#define PMIC_PERIOD_NUM

HDD, short for harddiskdrive, is the English name of the hard drive. The most basic computer memory, we often say that disk C, disk D and other disks are hard drive, but we generally referred to as hard drive. Modern hard disk capacity is generally 40g, 80g, 120g, 160g and so on, currently the highest desktop level hard disk is 500g. Hard disks can be divided into 3.

One, what is LCD?
LCD is the LCD screen liquid Crystal
Display of the full name, mainly TFT, UFB, TFD, STN, such as several types of LCD display can not locate the program input point on the dynamic link library.
Notebook LCD screen is commonly used in TFT. TFT (Thin Film transistor) refers to the thin film transistor, each liquid crystal pixel is integrated in the pixel behind the thin film transistor to drive, so you can achieve high speed, high brightness, high contrast display screen info

The device model generates a virtual file system--SYSFS, which gives the user a way to access the kernel device from the user's space,
