實現目的：
1、I2C從機接收數據，也就是接收I2C主機的數據并顯示出來；
2、I2C從機發送數據，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；
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）->自動接收數據->調用VII_SlaveReadBytes()函數返回數據；
現在我們用兩個USB-I2C適配器對接，一個當主機，一個當從機，由于適配器內部I2C總線上沒上拉電阻，所以需要在SDA和SCL兩根信號線上分別接一個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，所以在選擇設備類型為從機之前需要先設置好相關參數，因為在選擇從機模式后會根據界面設置相關參數自動初始化適配器為從機，其設置從機相關參數如下：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.
