we useths8136VGAThe encoder is connected to the Imx6qDisp0_dat0~dat23. When resolution Less than or equal to 720p , image good quality however , If the solution is greater than 720p , pixels will run on 100MHz of The clock. We only need to modify NBSP;IPU_DISP.C as follows: uint32_t rounded_pixel_clk_upper, rounded_pixel_clk_lower; ... if (Rounded_pixel_clk Rounded_pixel_clk_upper = pixel_clk + pixel_clk/200; Rounded_pixel_clk_lower = pixel_clk-pixel_clk/200; }

We found that the Console mode of ubuntu 10.04 always switches to a default VGA mode (as if it was 640*480), and the following method does not work:1. edit/etc/default/grub and add text to the quiet splash of the row grub_cmdline_linux_default.2. Replace quiet splash with nomodeset noplymouth in the same line.3. Remove the comment before grub_terminal = console Failed to use all kinds of methods, suspected to be a service, searched for rcX. d/RCS.

By gooogleman@foxmail.com Some old man asked me about the debugging of my 2440 + sm502 solution. In view of my understanding of the cost and performance of sm502, I think it is really unnecessary to use it again. The reply is as follows: I have used this 2440 + sm502, but I do not recommend that you use this solution, because 2440 and sm502 are all at the edge of production. When you make it, you don't have to sell it. The cost is also very expensive. sm502 is about one hundre

In simple terms, the key technology is: the Registrar mode.Scenario Requirements We know that when writing a class, the class itself has a purpose, there are many methods in the class, and each method does something, and we call this class the main class. In addition, this main class will rely on some other classes of help, we call these classes as sub-class, in order to achieve the main class target, to rely on a number of classes to match, and the second class is likely to be wide

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

If you need to play video in large venues, need to use two projectors, now the projector, a lot of two video interface, an input, an output, then we use a notebook with two projectors in tandem. This principle is the same as the computer with dual display video, it is necessary to have a separate video card and have two out of the interface. 　Method/Step 1 before doing these things, we first need to determine the specifications of their own instruments performance. We can first lo

 Since the installation of NVIDIA graphics card driver has been in the loop login interface, password input is correct is not to go, and then decided to uninstall the Nvidia graphics card driver.First, when you can log in using tty1, use the$ sudo apt-get autoremove--purge nvidia-*$ sudo rebootThen found that the boot can go into the desktop, very happy, the result is to switch to TTY mode is a black screen, in fact, is not a black screen, is due to uninstall the Nvidia driver, screen resoluti
