I. Summary This blog post combines video collection, compression, bus switching, and UDP data transmission to develop a UDP-Based Network Camera. The following describes the specific development process. For the debugging process of some key issues, see the next blog. Ii. Experimental Platform Hardware Platform: diy_de2 Software Platform: Quartus II 9.0 + NiO II 9.0 + Visual Studio 2008 Iii. Experiment Principles 1.

The experience sharing activity of the tianembedded Development Board ushered in the first article. After review, it was approved to meet the requirements. Next, let's share it. I am a newbie. I can only implement the functions simply. The following is a simple function of the development manual. I operate it according to it, and I will do it right away. In fact, development manuals are comprehensive. After researching the development manuals, you will not be asked questions about idiots, whi

This section describes several common features: Hvga (half-size VGA)That is, half of VGA (640*480), resolution (480*320), (Aspect Ratio ). QvgaThat is, "quartervga ". The size of VGA is 1/4, that is, the resolution output on the LCD is 240x320 pixels. WqvgaFull name: wide quarter video graphics ArrayA digital product screen resolution, representing a screen re

Author: gooogleman@foxmail.com I slept a lot today, so I started debugging with sate210 with VGA work control board tonight, because I saw that the P clock and parameter standards were not very high, so I thought, the maximum LCD pixel clock of s5pv210 is 166 m, so it fully meets the 1080 p 1920*1080 resolution requirements. So I filled in the parameters according to the standard and modified the related clock PARAMETERS OF THE sate210 wince system, O

/inittabFile, and the running level in Ubuntu is also different from the traditional RedHat Linux. In Ubuntu, the running level 2 \ 3 \ 4 \ 5 enters the graphic interface. Don't ask me how I know it. I will talk about it later. Let's talk about how to enable FrameBuffer and set the FrameBuffer resolution. The network method has long expired. To enable FrameBuffer on the network, you need to modify it first./etc/modprobe.dTo load the vesafb kernel module, you also need to modify Grub to pass

It is equipped with a 13.3 Inch "wxga" mirror highlighted magnificent screen with a resolution of 1280x800. 　 Front and back of the machine 　 Left and right of the machine Shenzhou q310y provides the following body interfaces: 3 USB2.0 interface, s terminal, ieee1394 interface, 1 PCMCIA expansion card slot, VGA port, headphone interface, microphone interface, DC power connector, travel battery connector, RJ-45 interfa

indicator of all display devices, LED display as a display device is no exception, below we have a brief explanation of the common interface:VGA input interface: The VGA interface uses the asymmetric distribution 15pin connection method, its working principle: is the video memory inside the digital format storage image (frame) signal in the RAMDAC to simulate the high frequency signal, then the output to the plasma imaging, so the

line to transmit signals. The interface is a four-pin interface. In the interface, the two pins are grounded, and the other two pins transmit the brightness and color signals respectively. Because the brightness and color signals are sent separately, the effect of the S terminal is better than that of the composite video. However, the anti-interference capability of the S terminal is weak, so the length of the S terminal line should not exceed 7 meters. 4 chromatic aberrationThe color differen

Differences between drawable-hdpi, drawable-mdpi, and drawable-ldpi: In Versions later than Android2.1, there will be three directories: drawable-mdpi, drawable-ldpi, and drawable-hdpi, these three directories are mainly used to support multi-resolution. Dpi is the abbreviation of "dot per inch". The number of dots per inch. Four types of density classification: ldpi (low), mdpi (medium), hdpi (high), and xhdpi (extra high) General screen: ldpi is 120, mdpi is 160, hdpi is 240, and xhdpi is 320.
