主机的英语翻译 主机用英语怎么说

主机输入从机输出

[词典]

master

input,

slave

output

缩写为

miso

master mode 主机模式 （下面例子中老大的模式）

slave mode 从机模式 （下面例子中小混混的模式）

master or slave transmit mode 主机或者从机 发送模式

master or slave receive mode 主机或者从机 接受模式

i2c是一个传输的协议，可以通过协议来传递数据，需要有SCL时钟线和SDA数据线

主机就像老大，控制时钟线，从机就像小混混，小混混可以有1个或者多个 每个有固定的编号

也就是地址，老大如果要叫小混混打一个人，先发送小混混的编号（地址），小混混确认后，老

大再发打人的资料（数据），然后小混混得到数据 ，去执行，这就是主机模式！

小混混如果要叫老大救命（数据），就要先申请，掌控时钟线，然后按上述类似步骤，这就是从

(1) single-chip 3 to the way communications, a data section 9 for the "1" on behalf of the address frame, in order to "0" on behalf of the data frame.

(2) to set the communication baud rate is 1200bps.

(3) 00H is the address of a frame sent from the machine work on all of the control order, order the resumption of the slave SM2 = 1, waiting to receive state.

(4) and from the host machine for the contact process

Host Address frame issued by the call from the machine frame to host the return address in order to determine the host machine from a contact. Host control commands issued from the machine in accordance with an order or to receive the host data blocks or data blocks sent to the host.

(5) control the host sending the command code as follows:

AAH: set table baseBBH: the number of read tableCCH: open table settingsDDH: clearance table settings

EEH: Checksum errorEDH: at the end of transmission.

(6) the composition of the format of data blocks: one block for the final at the end of EDH, until at the end of the contents of the data blocks can be frame opcode, address, code frames and data frames.

In order to achieve multi-machine communications, all firing circuits and all the oscillation frequency of the oscillation frequency receiver circuit must be adjusted in line, in order to ensure the normal communications, to prevent their own fat, then the direction of data transmission must be half-duplex transmission, transceiver in the launch must be shielded to receive its own interrupt, interrupted open after the end of the launch. Multi-machine communication process as follows:

(1) all from the machine SM2 = 1, at the address to receive the status of frame.

(2) a host address information, which includes 8-bit address, the first 9 to "1", with the required contact from the machine.

(3) from the machine after the address information received, each with its own compared to the addressin line for the address from the machine so that RI = 0, TB8 = 1, to send its own address, and SM2 = 0, TI = 1, to wait for the receiving host then sent all the informationthe address does not match the slave remained SM2 = 1 state, then sent to the host of the data sent up to take no notice of a new address information.

(4) to address the host will receive SCON 9th TB8-ching "0", and then proceed to address proof, address proof, if passed, from the machine has been contacted, send control commands to the communications signaladdress error proofing on there is no contact from the machine, send the end of the communication command, modify SCON 9th, TB8 home will be "1." Addressing the host to be sent from the machine control commands and data, a data section 9 for the "0", that send data or control commands.

5) called from the plane after receiving a command to the command analysis information collected at the scene to carry out certain data processing, in accordance with the requirements of the host to return data and the implementation of the host orders. If an order to end the communication, then immediately buy SM2 = 1, the end of this communication, to wait for the next communication, otherwise the implementation of appropriate action, for an order to return information, home TB8 = 0, return the correct information in response to post-SM2 = 1, to resume its only state to receive the address data frame.

(6) host receiving orders to return to the end of communication message SCON modify the first nine, will be home TB8 "1", ready for the next round of communications.

2. Hardware

Mainly include the infrared transmitter and infrared receiver circuit of two parts:

Infrared transmitter

Data transmission in the infrared signal modulation methods, the use of pulse modulation of the binary code is not zero. This modulation is simpler, more convenient all codec will help simplify the circuit. Infrared emission circuit as shown in Figure 2.

455KHZ the crystal by CRY, inverter 74HC04 and resistors, capacitors consisting of the square wave oscillator signal generated 455KHZ. By the pulse divider 74LS92, six of the pulse frequency as a signal 75.83KHZ. Another D flip-flop consisting of 2-/ 38KHZ shaping circuit into a square wave signal. By the single-chip asynchronous serial port TX of the serial data output signal to the NAND gate input of the 74HC00. Doors with non-38KHZ another input termination of the carrier signal. And non-gate transistor used to control the output signal of the open or off to control the launch tube infrared send a message. This achieved by the serial port TX of the serial data output directly modulated carrier signal to carry out the purpose of infrared data transmission. Transmitter modulation system using time division modulation keying rate. After the reduction due to single-chip, TXD pin is high, in order to meet the requirements of synchronous, use of low-level synchronization pulse, with the non-gate (U3) become high after the synchronization pulse. Therefore, single-chip encoder TXD should be sent by the anti-code.
