With the continuous development of single-chip microcomputer applications, there are more and more multi-chip systems composed of multiple single-chip microcomputer, and information exchange between multiple single-chip microcomputer is a whole. The work of a single-chip microcomputer is divided into multiple single-chip microcomputer. On the one hand, the performance of the system can be improved, and on the other hand, the hardware design of the sys

Now some hosts have multiple NICs how to configure each NIC with a different IP address for the same network segment:1. Use Ifconfig to see how many network cards are available: I'm hosts are Nic:eth0 and Eth8.An IP has been configured on the eth0 now I need to configure the IP address on the ETH82. First check that the NIC is well connected: for example, if the light on the interface is shining, the line of the interface is goodTool Ethtool View: Ethtool Eth8, Show Link detected:yes indicates

During multi-host communication, the RS232 interfaces of all devices are on the communication line. Only one device can be a host, and the others can be a slave device. The communication is initiated by the host. Generally, a data frame uses one start bit and nine data bits. Among them, 9th bits (rxb8) are used to indi
