is used as the pull-up resistor for the EEPROM i²c interface. Let's talk about how Cape works. Angstrom Linux uses device tree to bind hardware and drivers, and to set the multiplexing capabilities of the chip pins, a default device tree (suffix dtb) is stored in the system kernel, which is loaded first at startup. Then use device tree overlay, on the basis of this default device tree "overwrite" (overlay) on the new hardware and driver or remap pin function, to be used to overwrite the file su

The video card is a bridge between the host and the display. After the display signal is processed, the video card must send the signal to the display card through the corresponding interface. The video card interface is used to output the video card. Video Card interfaces have developed very rapidly in recent years. The development from D-sub and S-video to DVI, hdmi and displayport is just a few years. Now, the video card interfaces on the market ar

to the Monitor section of the XFree86 configuration file. This section contains information such as the monitor's horizontal scan frequency range, vertical scan frequency range, and display mode supported by the monitor. Similarly, the automatic detection of the monitor means that the above information of the monitor is automatically read through the program. The correct settings play an important role in the normal display of XFree86. 　　 For display information detection, it must support vbe (

). When the monitor supports this extension, you can obtain the display details by calling the INT 10 h bios in the system real-time mode. You may need to call the following BIOS sub-functions: AH = 0x4F00 Obtain BIOS-level extensions for the VESA of the monitor AH = 0x4F01 Obtain a specific Display Mode Supported by the monitor AH = 0x4F02 Set the current video mode AH = 0x4F03 Obtain the current video mode AH = 0x4F04 Save/restore svga Display Mode AH = 0x4F15 Obtain the monitor's

Now most of the LCD TV with HDMI, CRT, chromatic aberration and other video input interface, if you can use a laptop to connect to the TV program, you can add an experience. Using HDMI is the simplest and most convenient way to connect a computer to an LCD TV, and for the moment, there are three types of interfaces commonly used for laptop-connected LCD TVs: Vga,dvi and

Now the size of the LCD TV is bigger, many families have bought a large 60-inch color TV. So, there are netizens think: if the laptop can connect the TV, on the 60-inch big TV to play racing games that much fun ah!

Compared to computer monitors, LCD TVs have the advantage of low screen prices. Is it possible for all LCD TVs to be used as monitors? The answer is, of course, not. To play the role of a good monitor, LCD TV must have certain conditions. If you're thinking about putting a high-definition TV on your desk, you need to know the following.

So overall, the first is the HDMI interface, followed by the DVI interface, and finally the VGA interface. First of all to determine what the LCD TV video input interface, if only VGA interface, then any one notebook can be competent; if there is a DVI or HDMI interface, then in the purchase of notebooks, we should pay attention to pick! Finally, if you want to use the fiber output audio signal, Then we sho

I have tried the VGA connection between Hp ipv2tx and Dell d610,Neither XP nor Vista can completely eliminate noises. (Note: Samsung la32a550p1r needs to be in audio control.Turn off the "Automatic sound companion" option to reduce the noise .) However, in either case, the battery is used only if the external power supply is not used,In addition, the audio is converted through Bluetooth, that is, th
