EXB-3720是基于Intel Skylake/Kaby Lake芯片組的標準3.5嵌入式主板，板載Intel Skylake 6代/ Kaby Lake 7代(3855U/3865U/6200U/7200U)處理器，1條DDR4 SODIMM內存插槽，最大支持16GB。集成Intel HD Graphics圖形控制器，支持VGA，HDMI，LVDS/EDP多種顯示接口。
MVI56-MCM增強通訊模塊,PROSOFT用戶(hù)手冊最多支持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)級別產(chǎn)品方案的打造能力，該條產(chǎn)品線(xiàn)在打造之初，就對其性能與市場(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)的廣泛認可，在多個(gè)客戶(hù)需求場(chǎng)景中落地 產(chǎn)品可應用于人工只能、人臉識別、工業(yè)控制、交通控制、工業(yè)自動(dòng)化、交互式客戶(hù)端、軍工等各種行業(yè)領(lǐng)域。適配器固件從V2.8.17版本開(kāi)始支持I2C從機功能，下面就針對這個(gè)功能的使用做簡(jiǎn)單介紹。
實(shí)現目的：
1、I2C從機接收數據，也就是接收I2C主機的數據并顯示出來(lái)；
2、I2C從機發(fā)送數據，也就是把數據傳輸到適配器里面后，主機能將這些數據讀出來(lái)；
從機接收數據工作流程：
初始化設備為從機模式（需設置從機地址）->自動(dòng)接收數據->調用VII_SlaveReadBytes()函數返回數據；
現在我們用兩個(gè)USB-I2C適配器對接，一個(gè)當主機，一個(gè)當從機，由于適配器內部I2C總線(xiàn)上沒(méi)上拉電阻，所以需要在SDA和SCL兩根信號線(xiàn)上分別接一個(gè)4.7K的上拉電阻到3.3V，然后運行USB-I2C Classic軟件，由于我們要配置適配器工作在從機模式下，所以在選擇設備類(lèi)型為從機之前需要先設置好相關(guān)參數，因為在選擇從機模式后會(huì )根據界面設置相關(guān)參數自動(dòng)初始化適配器為從機，其設置從機相關(guān)參數如下：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.
