Author | Dave Cartwright Translator | Wang Qiang Reviewer | Luo Yanshan IEEE 802.11ax-2021 (commonly known as IEEE 802.11ax, or the more familiar “Wi-Fi 6”) was approved on February 9, 2021, with a maximum speed of 1.2 Gbit/s per stream (where “stream” can be considered as a “channel”). It seems that every time a new … Read more
In SIEMENS industrial communication, the most commonly used methods are Serial; Profibus; MPI; and Ethernet communication. The maximum communication distances for each are described in the table below. Serial Communication Type Rate Maximum Distance RS 232C 300~115200bps 15 m 20 mA TTY 9600 bps 1000 m 19,200 bps 500 m 422/485 115.2 kbps 250 m … Read more
1. Introduction 1. Why use Ethernet for communication? Ethernet refers to a local area network that complies with the IEEE 802.3 standard. It is a type of internet technology, and since it occupies the highest proportion in networking technology, many people directly equate Ethernet with the internet. However, IEEE also has other local area network … Read more
Image course, development board –> Taobao store: Wolf FPGA ConsultationWeChat: MyWork666888 QQ group: 543928922 Recently, Wolf published an article on 100G networking titled “FPGA Project: 100G Network Development Sharing”. It is impressive that it can communicate, but the downside is that it only reaches the MAC layer, and the upper network layers are missing. To … Read more
As a classic communication protocol in industrial automation, Modbus has been widely used globally since its inception in 1979. From the initial serial communication to today’s high-speed Ethernet links, Modbus has undergone technological evolution and expansion, marking a milestone in the field of industrial communication.

In this article, we will introduce how to quickly set up Ethernet on an FPGA (using LWIP). For this purpose, we will use MicroBlaze as the main CPU to run its application. LWIP is a good starting point for designing Ethernet with bare metal, on which we can easily adjust the software application to provide … Read more
2.6 Using Renesas Flash Programmer Software Setting Security Boundaries Notes When the chip is shipped from the factory, its DLM state is set to “CM” by default, and the IDAU security boundary is not set. In this state, users can normally use most peripherals of the chip, except for a few peripherals, such as Ethernet … Read more
