we use the popular saying to explain to everybody: Half Duplex (Half Duplex), so-called half-duplex means that only one action occurs in a time period, as a simple example, a narrow road, and only one car to pass, when there are currently two vehicles off, in this case can only be one before the first, wait until the boss after the other one to open, This example illustrates the principle of half-duplex in the image. Early walkie-talkie, as well as early hubs and other devices are based on Hal

think that dbm is the maximum value of 0, meaning that the receiver of the transmitter launched all the wireless signal received, that is, the wireless router fired how much power, the reception of the wireless network card to obtain how much power. Of course, this is measured in an ideal state, in practice, even if the wireless network card next to the wireless router transmitter antenna will not achieve

of the data, and 1 reads. See below for details:The data transfer is terminated by the host-generated termination condition (P). However, the host can also generate a duplicate start condition (Sr) and address another slave without first terminating the condition,The possible data transfer formats are as follows:The master-transmitter is transmitted to the slave-receiver. The transmission direction is constant. From-the receiver answers each byte. as

During the differential transmission of twisted pair wires, for external interference signals, the two twisted pair wires are equivalent to the Same conductor, and the interference signals have the same amplitude and polarity on the two wires. At the input end of the differential amplifier, if the CMR value of the two-wire common mode input is large enough to receive the difference amplifier, it can be well restrained. Generally, the characteristic impedance of the Communication twisted pair is

to break the conventions is that when an inventor invented a car, he still wanted to operate the car with the manipulation of the carriage. As a result, instead of using the steering wheel, he planned to adjust the direction of the car with the reins! In the history of science and technology development, there are countless examples of valuable innovation by breaking the conventions. When wireless communication was just invented, almost everyone agreed that the ultimate goal of the evolution of

Conversion of wireless power mW and DBM and interpretation of common symbols 1. Conversion of power unit mW and DBM The RF signal output by the radio transmitter is transmitted to the antenna through a feeder (Cable), which emits electromagnetic waves. After the electromagnetic wave arrives at the receiving location, it is received by the antenna (only a small portion of the power is received) and sent to the radio receiver throu

MIIMedia independent interface (media-independent interface); or media-independent interface, which is the Ethernet industry standard defined by the IEEE-802.3. It includes a data interface and a management interface between MAC and PHY. Data interfaces include two independent channels used for the transmitter and receiver respectively. Each channel has its own data, clock, and control signal. The MII data interface requires a total of 16 signals. Man

ancients once hadAccording to the imagination, Xiang Yu once hacked Qin Ling with 0.3 million people. Suddenly a kind of geese flew out of the tomb and kept facing south. In the first year of the Three Kingdoms Bao Ding, some people sent Jin Yan to Zhang Shan's officials.The word can tell at a glance that this thing is from the beginning of the Emperor's mausoleum. 7. "The Mystery of mercury," Sima Qian said. At the beginning, HuangLing began to use mercury as rivers and seas, and machines we

The first difference is of course the name:SPI (serial peripheral interface: serial peripheral interface );I2C (Inter IC Bus)UART (Universal Asynchronous Receiver Transmitter: Universal asynchronous transceiver)Second, the difference lies in the electrical signal line:The SPI bus consists of three signal lines: sclk, SDO, and SDI ). The SPI bus allows multiple SPI devices to connect to each other. The SPI device that provides the SPI serial clock is t

Nowadays, wireless LAN has become the mainstream in the market, and its security cannot be ignored. In a wireless LAN, data is transmitted through radio waves in the air. Therefore, data within the range of the transmitter can be received by any wireless LAN terminal. Installing a wireless LAN is like placing Ethernet interfaces anywhere. Therefore, the use of wireless LAN Nowadays, wireless LAN has become the mainstream in the market, and its securi

However, a microcontroller without such an interface needs to sample the SDA line at least twice in each clock cycle to determine whether a level switch has occurred.
