In the Linux based video surveillance acquisition system, the camera captured a frame of video image data are generally hardware automatically compressed into the JPEG format, and then saved to the camera device buffer. If you want to display the collected JPEG format on the local LCD screen, Since our Linux system does not transplant any GUI systems, consider the following: 1. Unzip JPEG format to bitmap format, i.e. JPEG decoding. 2. The decoded bit
To solve the problem of LCD Font hollow, the first thing is to check whether the resolution of the LCD is correctly set. The LCD will have an optimal resolution, like a 19-inch widescreen LCD is 1440*900 (partly 1680*1050), and a 22-inch widescreen LCD is 1680*1050, and font
From: http://blog.csdn.net/dongliqiang2006/archive/2009/06/12/4262950.aspx [Excerpt ]:After Linux is started, as long as the keyboard does not move for a period of time (the keyboard extended by I/O on the Development Board), the LCD will be automatically closed (black screen, display slowly disappears and so on), as long as you press the keyboard to restore. This problem took me more than a day. In fact, this is nothing if it is a handheld device. Ho
I recently got the LCD screen of Jinpeng. Now, I don't want to run the LCD screen.ProgramI can't say it. It would be better if I could use 3G modules and WiFi modules. This LCD screen has nothing special than other LCD screens. Some time ago, I used a LCD screen without a

The 12,864-point array liquid crystal display module (LCM) is an array of 128-column *64 rows consisting of a 128*64 LCD display point. Each display point corresponds to a binary number, 1 for light, and 0 for off. The RAM that stores these lattice information is called the Display data memory. To display a graphic or Chinese character is to write the corresponding lattice information to the appropriate storage unit. The lattice information of a graph

Because of the particularity of the notebook LCD screen, LCD panel in the factory or in the use of the process is very easy to have a bad situation, once encountered them, if the manufacturers have a better policy to protect the point, can be replaced by distributors or return to plant repair, but if within the scope of the manufacturer's provisions (generally under 3 points below), Then users can only thin
CRT monitor CRT monitors need to be aware of the following issues in their daily use: 1.CRT monitors should be aware of moisture, long-term use should also be regularly energized to disperse the moisture in the monitor. 2. Adjust the brightness and contrast of the display, so that the screen display is not too bright, to avoid the rapid aging of the picture tube. 3.CRT display should be away from the magnetic field, lest the picture tube magnetization, appear jitter, flicker and so on. 4.
At present, the general color LCD connection mode has so many: MCU mode, RGB mode, SPI mode, VSync mode, Mddi mode and so on. ========================================================================================= First, the hardware interface MCU mode: currently the most commonly used connection mode, usually 80 system (68 system no longer exists). Data bits are transmitted in 8-bit, 9-bit, 16-bit, and 18-bit. The connection is divided into: cs/,rs

I have previously compiled a small tool "LCD debugging Assistant Under wince" for LCD debugging, which is now useful. The hardware Team helped to fly two lines. After the system was started, the system was displayed. Because the resolution of
LCD computer monitors can not adjust the brightness, or after the adjustment will flicker, with a long time will also blink, but sometimes back to normal. Voltage or surrounding electrical appliances may cause the LCD screen flicker, at the same time the internal contact is bad or high pressure plate problems will cause the above phenomenon. When this happens, the display can be moved elsewhere, and
