1. Materials used: STM32F103C6T6 Minimum System Board STM32CUBEMX (HAL library software) MDK5 Serial debugging assistant 2. What you learned: Preliminarily learn how to use the CAN communication function of STM32. In this chapter, we mainly achieve the effect of on-board CAN communication, that is, 32 sends CAN information and then prints it out through the […]

The wonderful world of virtual interfaces: the incredible uses of LoopBack, NULL, and InLoopBack
Hello, this is the Network Technology Alliance site. In the world of computer networks, various interfaces and protocols form the basis of network communication. In network device management and configuration, LoopBack interface, NULL interface and InLoopBack interface are special and important virtual interfaces. Although they are not eye-catching, they play a key role in the […]
Comparison of data writing speed between AF_UNIX and 127.0.0.1 (AF_INET) loopback address (2)
I wrote a blog before: Comparison of data writing speeds between AF_UNIX and 127.0.0.1 (AF_INET) loopback addresses Then we used the sending end to read a large file, and the receiver received and saved it as a file for testing. It was found that AF_UNIX is not better than the 127.0.0.1 (AF_INET) loopback address. If […]
Comparison of data writing speeds between AF_UNIX and 127.0.0.1 (AF_INET) loopback addresses
Under Linux, there is a situation where local inter-process communication occurs, and one of them is the server and the others are clients. This can be done by binding the port on the server and sending the client to the corresponding port of 127.0.0.1. However, this will waste a port and easily cause security risks. […]
