实现目的:
1、I2C从机接收数据,也就是接收I2C主机的数据并显示出来;
2、I2C从机发送数据,也就是把数据传输到适配器里面后,主机能将这些数据读出来;
从机接收数据工作流程:
初始化设备为从机模式(需设置从机地址)->自动接收数据->调用VII_SlaveReadBytes()函数返回数据;
现在我们用两个USB-I2C适配器对接,一个当主机,一个当从机,由于适配器内部I2C总线上没上拉电阻,所以需要在SDA和SCL两根信号线上分别接一个4.7K的上拉电阻到3.3V,然后运行USB-I2C Classic软件,由于我们要配置适配器工作在从机模式下,所以在选择设备类型为从机之前需要先设置好相关参数,因为在选择从机模式后会根据界面设置相关参数自动初始化适配器为从机,其设置从机相关参数如下: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.
