MVI56-MCM增強(qiáng)通訊模塊,PROSOFT用戶手冊(cè)最多支持6個(gè)串口，4個(gè)USB3.0，2個(gè)USB2.0（插針），2個(gè)Intel 10/100/1000Mbps以太網(wǎng)口，支持高清音頻輸出，帶功放。 研控科技EXB-3720工業(yè)級(jí)別產(chǎn)品方案的打造能力，該條產(chǎn)品線在打造之初，就對(duì)其性能與市場(chǎng)定位進(jìn)行了清晰的分析，精心打造出的產(chǎn)品方案，上市后得到市場(chǎng)的廣泛認(rèn)可，在多個(gè)客戶需求場(chǎng)景中落地 產(chǎn)品可應(yīng)用于人工只能、人臉識(shí)別、工業(yè)控制、交通控制、工業(yè)自動(dòng)化、交互式客戶端、軍工等各種行業(yè)領(lǐng)域。適配器固件從V2.8.17版本開始支持I2C從機(jī)功能，下面就針對(duì)這個(gè)功能的使用做簡(jiǎn)單介紹。
實(shí)現(xiàn)目的：
1、I2C從機(jī)接收數(shù)據(jù)，也就是接收I2C主機(jī)的數(shù)據(jù)并顯示出來；
2、I2C從機(jī)發(fā)送數(shù)據(jù)，也就是把數(shù)據(jù)傳輸?shù)竭m配器里面后，主機(jī)能將這些數(shù)據(jù)讀出來；
從機(jī)接收數(shù)據(jù)工作流程：
初始化設(shè)備為從機(jī)模式（需設(shè)置從機(jī)地址）->自動(dòng)接收數(shù)據(jù)->調(diào)用VII_SlaveReadBytes()函數(shù)返回?cái)?shù)據(jù)；
現(xiàn)在我們用兩個(gè)USB-I2C適配器對(duì)接，一個(gè)當(dāng)主機(jī)，一個(gè)當(dāng)從機(jī)，由于適配器內(nèi)部I2C總線上沒上拉電阻，所以需要在SDA和SCL兩根信號(hào)線上分別接一個(gè)4.7K的上拉電阻到3.3V，然后運(yùn)行USB-I2C Classic軟件，由于我們要配置適配器工作在從機(jī)模式下，所以在選擇設(shè)備類型為從機(jī)之前需要先設(shè)置好相關(guān)參數(shù)，因?yàn)樵谶x擇從機(jī)模式后會(huì)根據(jù)界面設(shè)置相關(guān)參數(shù)自動(dòng)初始化適配器為從機(jī)，其設(shè)置從機(jī)相關(guān)參數(shù)如下：注意
load balancing can be set. The most important point is that the backplane bandwidth of the core switch is much higher than that of the ordinary switch, and there is usually a separate engine module, which is the main and standby.
Access layer switch has the characteristics of low cost and high port density. Access switches are generally used to directly connect computers, and convergence switches are generally used between buildings. Convergence relative to a local or important transfer station, the core is equivalent to an exit or general summary.service life
The service life of industrial switch is > 10 years. However, the service life of ordinary commercial switches is 3-5 years.
Why look at the service life? Because it is related to the later maintenance of the project. Therefore, in the video transmission in the network monitoring environment such as parks, office buildings and parking lots, as well as the data transmission in the scenes such as visual intercom and access control in buildings, which need high-definition video streaming transmission, switches with comparable performance with industrial switches should be selected.
