Reprint: http://www.eefocus.com/article/08-07/48416s.htmlFigure 11-1 shows a single-master IIC bus system with 3 slave machines from the MCU as a host through the IIC bus. This is the most commonly used, the most typical IIC bus connection mode.On the physical structure, the IIC system consists of a serial data line SDA and a serial clock line SCL. The host addresses and transmits information to the slave according to a certain communication protocol. At the time of data transmission, the host i

Vi. Particle System The special effect described below is more interesting: a particle system. In the irrlicht engine, the particle system is both componentized and scalable, but still easy to use. You just need to put the particle transmitter in a particle system scene node, so that the particle seems to have no source. These transmitters can be flexibly configured as needed and often carry many parameters, such as particle direction, number of par

Modulation carrier frequency generally between 30khz to 60khz, most of the use of 38kHz, duty-free 1/3 of the square wave, 2, which is used by the transmitter side of the 455kHz Crystal determined. On the transmitter side to the Crystal Oscillator integer division, the frequency division coefficient is generally taken 12, so 455khz÷12≈37.9khz≈38khz.Figure 2 Carrier Waveform3.2, the Launch Sys

I have DIY one Android remote - all open source1. TrialRemember Song Baohua in the "device-driven development specific explanation" put forward a theory "software and hardware infiltrate each other's territory", this proves to be true, the use of the upper-level APP software with simple and simpler hardware design can complete a remote control. Have developed the application of Internet users e-mail asked how the DIY Infrared remote control is how to work. Check it out. There are two ways to do

IntroductionEthernet is the most successful LAN (local area Networking) technology in the last 30 years. 1. First widely used LAN technology (a widely used LAN technology) 2. Kept up and speed race:10 mbps–100 Gbps 3. connectionless: No handshaking between sending and receiving NICs (network Interface card, network card) No connection is established. 4. unreliable: receiving NIC doesn ' t send ACKs or nacks to sending NIC Not reliable. Ack:acknowledgement, that is, the confirmation character, in

-signature matching. Figure 1 Delegate successful output Now that we have a certain understanding of the delegate, next we will introduce the place where delegates are most often used-events. We will discuss events from the perspective of the transmitter and the receiver, for example, in UI programming, a mouse click or a keyboard key, and the transmitter is. NET's CLR, note that the event dispatcher does

distortions, in which each pixel in the output register corresponds directly to each pixel of the display. Make the picture quality has the basic safeguard. DVI Interface Technology The DVI interface is based on the Panallink interface technology of silicon Image company, and the Electronic Protocol of TMDS (Transition minimized differential signaling, minimized transmission difference signal) as the basic electrical connection. TMDS is a differential signaling mechanism that encodes pixel da

used to drive the SCL line; • Respond to the main device from the device Both can transmit data, but the transmission is not initiated from the device and the transmission is controlled by the master device. 4. Rate Normal Mode: 100kHz Quick mode: 400kHz High Speed mode: 3.4MHz There is no need to use a high speed SCL to keep the SCL at 100k or below; I. Agreement 1. Idle state The SDA of the I2C bus and the SCL two signal lines are at the same time at high power, which is defined as the idle

DescriptionWith the increasing popularity of smartphones, there is a growing demand for wireless networks. A city decided to cover the public places in the city wireless network. Suppose the layout of the city is a grid of strictly parallel 129 things to the streets and 129 north-south streets, and the distance between adjacent parallel streets is a constant value of 1. Things to the street from north to south, sequentially numbered 0,1,2 ... 128, north-south Street from west to east, sequential

, and then connect this broadband line to the wireless transmitter AP, and then on the computer need to install a USB port or PCMCIA wireless network card. The following is to set up a wireless network node, the role of wireless network node is the cable network signal into the wireless signal, its location determines the entire wireless network signal strength and transmission rate, positioning is very important. First, the wireless AP and LAN comp

Ethernet ports have three types of links: Access, Hybrid, and trunk: The connection terminals of these three types of links are different: Access type ports can only belong to 1 VLANs and are typically used to connect to a computer's port; The trunk type port allows multiple VLANs to be passed and can receive and send packets of multiple VLANs, typically used for connecting ports between switches; The hybrid type port allows multiple VLANs to be passed, can receive and send packets of multip

Of course, the HDFs client and the Datanode node receive blocks differently, but this article will focus on the data b

The I²c bus is designed by NXP (formerly Philips) and has a very concise physical layer definition with the following characteristics: As long as the two bus line: A serial data line SDA, a serial clock line SCL; Each device connected to the bus can have a unique address and a simple host From the system software to set the address, the host can act as a host transmitter or host receiver; it is a true multi-host bus, and if two or more hosts are initi

interval, and the following image shows the PT2262 encoding diagram: As shown above, each signal sent by the transmitter will carry a multi-uncorrupted set code loadline, each encoding loadline value is the same, the binary value is 0b010101010101010100001100, the corresponding hexadecimal code value is: 0x55550c. As can be seen from the graph, the period of the transmission code is equal, but the pulse width is different (the ratio of wide pulse to

spread spectrum signal, such as using brute force injection (jamming) if your signal is sent to the signal to be disturbed (DoS attacks are denied), attackers must know this equation accurately, and the start time of using this equation (because the transmitter can change this equation at any time, so that it can be easily transferred to other frequencies ). therefore, the confidentiality of these equations in an application must be guaranteed.Most s
