RTS and CTS in the RS232 standardrts,cts------Request Send/clear send, for half-double hours of transceiver switching, belongs to the auxiliary flow control signal. Half-duplex means to say that when the hair is not received, when the collection is not sent. So how do you differentiate between sending and receiving? By default, the DCE sends data to the DTE, and when DT

Serial Communication Overview There are many kinds of serial communication protocols, such as rs232,rs485,rs422, even the popular USB is serial communication protocol. And the application of serial communication technology is everywhere. Perhaps everybody sees most is the computer serial port and the modem communication. Remember when the PC was first popular in China (about five years before the 90 's), when someone even used a serial line to share

is, just read the data it finds, or write the data it needs to write.The simplest way to number a sector is to 1,2,3,4,5,6 sequential numbers. If the sectors are numbered sequentially around the track, then, during the process of processing a sector's data, the disk rotates too far, exceeding the interval of the sector (the interval is small), and the next sector that the controller reads out or writes to has passed through the head, perhaps a considerable distance. In this case, the disk contr

improve, the positive and negative deviation value will be reduced. The macd is based on the sales signal by using the cross signal of the positive and negative deviation (± DIF) and the N-day average (n-day EMA, that is to say, we analyze the sales signal again with the crossover principle of fast and slow moving lines. In addition, macd indicators in the stock market software also has a secondary indicator-Bar = 2 × (DIF-DEA ), we can still use the

At present, all optical network is not the whole network optical, but refers to the optical information flow in the transmission and exchange process in the form of light, with the circuit method to achieve the control part. From the current situation and development trend of optical electronic componen

Shield registers are mainly used for receiving and sending enable. Therefore, for the UART protocol, the above registers are very important, they mainly complete the baud rate configuration, protocol selection, sending and receiving judgment and processing.

sectors are skipped, that is, the second sector is the second sector, this process continues until a logical number is assigned to each physical sector. For example, if a disk with 17 sectors on each track is numbered by a crossover factor of 2: 1: l, the crossover factor numbers based on 3: 1 are: l. When the cross factor of 1: L is set, if the hard disk controller processes the information fast enough, i
