I. Purpose Familiar with barebox frame buffer framework, LCD Driver porting and test command writing. Ii. Main Content Port the tiny6410-based LCD driver to the barebox in 1.1. 1.2 compile an LCD command to test the LCD driver. 1.3 write the RZ command so that you can download files to the memory through the serial po

1. Avoid unnecessary vibrations LCD can be regarded as the most sensitive electrical equipment, LCD contains a lot of glass and sensitive electrical components, so that the screen is very fragile, to avoid strong shock and vibration, strong impact on the LCD screen and CFL unit is very easy to damage. Be careful not to exert pressure on the

The first taboo: moisture invasion Water can be said to be the first natural enemy of liquid crystal. The destructive power of water to the LCD screen is astonishing. So you should put the LCD in a more dry environment to use, do not let moisture into the LCD inside. For some users with a more humid working environment, you can buy some desiccant to keep the air

Author:Liu Peng Date:2008-12-27 This paper analyzes the main data structure of the frame buffer device driver, and introduces the LCD driver.ProgramDevelopment. Basic Principles Through framebuffer, the application uses MMAP to map the video memory to the virtual address space of the application. The data to be displayed can be displayed on the screen after being written to the memory space; The driver allocates system memory as the memo

Here, we use the icool2416 Development Board u-boot version 1.3.4 of Guangzhou SDO. LCD driver and serial synchronous output are added at the same time. Modify as follows: Add the following file gzsd2416-lcd.c under the drivers/video directory (with u-boot source code as the Directory), gzsd2416-lcd.h and s3cfb-reg.h content as follows: Gzsd2416-lcd.c, LCD initialization and backlight control /* * Gzsd2416

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

Like 6 s models, iPhone 7 and iPhone 7 Plus have different screen sizes and cameras. Let's first take a look at the parameter comparison between the two mobile phones. Differences between iPhone 7 and iPhone 7 Plus Comparison model

ThinkPad-how to maintain and clean the LCD screen and precautions Applicable models: All laptops Document Content: Symptom: There are scratches or scratches on the LCD screen. This trace is caused by a backlog of external force on the screen shell, which makes the trackpoint mouse or keyboard buttons touch the LCD screen. Configuration: ThinkPad laptop Solution:

Fundamentals of 1 system 12,864 point formation liquid crystal display12,864-point array graphic liquid crystal display application, one through C51 programming realizes to the LCD12864 LCD screen control, the liquid crystal display (LCD) has the low operating voltage, the micro power consumption, the display is flexible, the low cost characteristic. The data in the digital circuit is saved in 0 and 1, and

set, and red, green, blue, and transparency are 8 bits respectively. Or ARGB8888 is similar, just note the order and offset when you set the data structure. In the frame buffer device, the operation of the screen display point is done by reading and writing display buffer, in different color mode, the display buffer and the display point on the screen have different correspondence, showing a pixel point 8-bit and 16-bit case of the display buffer and display point of the corresponding relations

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

Xu: http://blog.csdn.net/hduxyc/article/details/6426463 FSMC stands for static memory controller ". After the FSMC controller is used, the fsmc_a [25:0] provided by FSMC can be used as the address line, and the fsmc_d [] provided by FSMC can be used as the data bus. (1) When the storage data is set to 8 bits, (fsmc_nandinitstructure.fsmc_memorydatawidth = fsmc_memorydatawidth_8b) The address corresponds to fsmc_a [], and the data bit corresponds to fsmc_d [] (2) When the storage dat
