I. MX6Q (TQIMX6Q/TQE9) Study Notes-New bsp LCD porting, tqimx6qtqe9 After the above transplantation, eMMC can run properly on tqimx6q. This article will transplant the LCD driver in the future. Write data through DTS The LCD controller of imx6 is slightly different from the previous one. For more information, see the chip manual. Refer to the data transmission on

To the photographic enthusiasts to believe that the resolution to share the Canon 600D camera LCD screen focusing on the problem of dimming solution. Ways to share: Canon 600D LCD screen After focusing dimming may be a power-saving function, and then try half press the shutter, whether again back to normal. Okay, the above information is small make up to all the photography enthusiasts brought to t

In front of the use of USB camera to collect BMP pictures and YUV video, the display process is directly to the BMP picture in the LCD display on it. The general USB camera operation as in front of the same, not clear camera operation can gohttp://blog.csdn.net/zhangdaxia2/article/details/72763847. Framebuffer operation is not difficult, as follows:The Framebuffer device node is/DEV/FBX. Generally for/dev/fb0, a liquid crystal control node. Operation

LED display compared with LCD display, led in brightness, power consumption, visual angle and screen update rate, etc., have more advantages. LED and LCD power consumption is about 10:1, and the higher update rate makes the LED in the image has better performance, can provide 160° perspective, can display a variety of text, digital, color images and animation information, can also play TV, video, VCD, DVD a

LCD Common Interface "LVDS,TTL,RSDS,TMDS" Technology Principle Introduction1;lvdsLow-voltage differential signaling low voltage differential signalA signal transmission model, proposed by the National Semiconductor Company in 1994, is a standardIt has a low power consumption while providing high data rates, and it has many other advantages:1. Compatibility of low voltage power supply2. Low noise3. High noise suppression capability4. Reliable signal tr

Show size (display size)Refers to the diagonal length of the actual viewable area, in inches, or inch (1 inches = 2.54 centimeters).Aspect ratio (aspect ratio)Refers to the ratio of the length and width of the visible area of the TFT-LCD, also called the screen scale. The main aspect ratio has 4:3,5:4,16:10,16:9 four kinds. A 16:9 ratio is closer to the golden section than the human eye is more comfortable to watch. The length is generally expressed i

The main reference is the 8th chapter of Am335x's TRM PRCM module and the 13-chapter LCD Controller. Here in the LCD controller inside the configuration described in more detail, the frequency division and pixel, the setting of the extinction value and so on. Not to repeat, many people will complain that the LCD_PCLK configuration can only be LCD_CLK through a crossover, so for frequency 70~90mhz configurat

This article is written in November 13, this is only a record of the knowledge that has been covered in this area, may be useful for some knowledge of the futureFor the platform bus model, you can refer to a previous article on the Linux driver platform bus model, which may be helpful for framebuffer driver registrationFirst, the LCD hardware frameworkSecond, LCD software frameworkThird,

1. Video off-the-shelf example only contains the tq2440 pair of 4.3-inch LCD driver code.However, I have a tq2440 7.0-inch LCD screen in my hand, so I checked the 7.0 screen manual and changed the parameters to be usable.If tq2440 is used, you can set the LCD parameters in the 7.0-inch screen driver example.The following two settings can be used. # Include

Not long ago, because the work needs to replace the LCD screen, the resolution from the original 800*480 replaced by the 800*600. Of course, change the LCD driver first, modify the corresponding parameters. The boot logo has also been replaced, the resolution modified to 800*600. But when the boot, the logo can not be displayed, prompted the following error. Fbcon_init:disable Boot-logo (Boot-logo bigger
