Linux Kernel version:3.0.35Platform:freescale dsa2lRead the EDID information of the VGA screen via i²c (mainly resolution), parse and feed the CH7036 chip (LVDS to VGA,DVI,HDMI Chip), provide the file node to user Space.Code flowBecause the EDID protocol specifies that the read slave address of I²c is 0x50, the device registration code is added first:I2c.h#define

interface should be and LCD hardware interface must correspond, so we should put the LCD controller output TTL interfaceSignal through the IC chip to convert it into the LCD hardware interface corresponding to the interface signal, so that they successfully complete the communication.(3) TFT-LCD Interface: TTL (RGB), LVDS, EDP, MIPI (these interfaces are also connected through the soft line, for mobile phones, tablets, etc.)(4) TTL (RGB) interfaceThe

Analog Interface The analog signal input to the TFT-LCD display device to show itself is a very ridiculous thing. The computer is running data, including image information, which is converted to analog signals on the display card, then transmitted to the monitor via the connector, and then displayed as a digital signal on the monitor, which is completely superfluous. And the consequences of this is clear, one is to increase the additional hardware overhead, the second is in the signal conversio

-E 2.0 port: In addition to hm70, um77 are four, the other are eight, can be split into x1, x2 or X4. PCI Bus: Only b75 retains native support, and all others are cut off. The corresponding motherboard can only be supported by a third-party bridge chip. USB 3.0/2.0 interfaces: z77, h77, z75, and hm77 are all complete 4/10, b75 and hm76 are reduced to 4/8, um77 is 4/6, and hm70 is only 2/6, hm75 is 0/12 (USB 3.0 is not supported ). SATA 6 Gbps/3 Gbps interfaces: z77, h77, z75, hm77, hm76, and hm7

Introduction Currently, analog interfaces have become the standard for desktop display, but the popular PFD display requires completely digitalized interfaces, because for flat display, analog interfaces are completely unnecessary, the digital interface does not have to adjust the clock and phase, and has the advantage of no loss in signal transmission. With the promotion of digital flat display, the need for digital graphics Connection becomes clearer. The DVI digital video interface standard p

D630, interl gm965 motherboard comes with a video card, once in 7.04, this video card makes us particularly uncomfortable, because there is no driver, and we want to display dual screen.The day before yesterday, my 7.04 system finally collapsed, inode went wrong, and the new file could not be created. I checked it with fsck, and the result was no longer available, so I had to reinstall it.Everything went fine, but I needed a dual-Screen Display (notebook and 22-Screen Display). First, check whet

Control System The Dacheng display control system consists of the acquisition/sending subsystem and the receiving/grayscale processing subsystem. Its front-end is the VGA feature output interface of the computer or a multi-media card with digital component output, transmission is implemented by cat5e twisted pair wires, and the backend is an electronic display unit. The acquisition/sending sub-system collects 24 bits real-color signals at a frame rat

Problem after Nvidia graphics card driver uninstallation and uninstallation in Linux Since the Nvidia graphics card driver is installed in Ubuntu and is always on the cyclic logon interface after it is started, the correct password cannot be entered, and then the Nvidia graphics card driver is uninstalled. The first step is to use tty1 to log on. $ Sudo apt-get autoremove -- purge nvidia -* $ Sudo reboot Then I found that I was able to enter the desktop when I started the desktop. The result was

disturbance of the critical value, and the signal will go wrong once the higher level or low level signal exceeds the critical value. In the differential transmission circuit, the output level is positive voltage is expressed in logic 1, the output negative voltage is the logic 0, and the output 0 voltage is meaningless, it does not represent 1, does not mean 0. In the differential communication, the interfering signal enters the adjacent two signal lines simultaneously, and at the signal recei
