Click the card above to follow for more information RS-485 is a physical layer bus design standard in industrial and instrumentation applications, and has become one of the most widely used standard communication interfaces in the industry.This communication interface allows for multipoint bidirectional communication over a simple pair of twisted wires, and its noise suppression … Read more
Summary Have you encountered occasional communication errors while debugging with the CAN or RS-485 bus? Or have you been unable to receive data? Did a bus that had been functioning normally suddenly experience widespread errors or node failures? If you are at a loss for these issues, using bus isolation might easily help you resolve … Read more
The RS-485 bus is a commonly used field bus in industrial communications, but industrial control environments are often harsh, and the bus can be subjected to various external disturbances that affect its reliability. Among these, Electrical Fast Transient (EFT) disturbances are common. Today, we will discuss how to test and eliminate the impact of pulse … Read more

Introduction The RS-485 bus is widely used in industrial communication, but harsh industrial environments can lead to external interference, such as Electrical Fast Transients (EFT), which affect its stability. This article explores how to test and mitigate the interference of EFT on the RS-485 bus. Sources of Pulse Group Interference In industrial control environments, disturbances … Read more
▲ Click Above to Follow STM32 In the past, developers often overlooked the security issues of embedded devices when discussing them, assuming that embedded devices are not easily susceptible to network attacks and are not targets for hackers, or that simply implementing encryption and authentication suffices for adequate security. However, in today’s world of the … Read more
Software architecture is a topic of much debate, with various viewpoints. What is software architecture? We can find countless definitions online. For instance, we can define it as follows: software architecture is the fundamental structure of a software system, reflected in its components, the relationships between components, the rules for component design and evolution, and … Read more
