stm32 ethernet

Unlike office and home Ethernet, which has long been well known, industrial Ethernet requires more professional knowledge and practical experience. If you are installing or using an industrial Ethernet, you must understand the Five Points of cabling, signal quality, grounding circuit, switch, and communication. Wiring problems Like all networks, the advantages an

Ethernet switches are still commonly used. So I studied whether SPOH technology has triggered the Ethernet switch revolution. I would like to share it with you here, hoping it will be useful to you. The rapidly expanding "Network Society" poses severe challenges to Ethernet switches serving as data processing centers. First, in the face of overload data transmiss

"Little Horn" is a radio program for children from the 50 's to the 80 's. At the beginning of the program, there will be a kind of broadcast: "Children, small speakers began to broadcast!" "Hearing here, the children in front of the radio get excited and ready to listen to the program: This issue is the

Three-dimensional out of the new At present, more and more manufacturers to enter the Ethernet market, new brands and new products continue to emerge, it seems that there has been a trend of homogenization of competition. However, it is worth mentioning that the Ethernet switch in the market number of expansion, while the quality requirements are also constantly improving. Just to meet the simple connectio

These things will not be confused, because they are not a level of East, now think about the early I feel some do not understand because the agreement is in the abstraction layer is not clear, the knowledge should be from the bottom solid walk.First, the agreement is not big, the agreement is the two sides agreed to abide by the norms, only that. The data transmission between the Internet is on the Ethernet, and it needs to do some processing before i

Generally, the Integrated Wiring System is updated every seven years. It takes five years to replace the three-category system with the Five-category system. It takes only three years, cat6 systems are mature and increasingly widely used. It is a trend to implement Gigabit Ethernet in cat6 systems, and standards for cat6 systems are being formulated and initially implemented, bringing copper cabling systems to the fullest is the latest goal of 10 Giga

1. Introduction The IEEE 802.3z Gigabit Ethernet Standard, adopted in June 1998, describes 3 physical layer interfaces (1000BASE-SX, 1000BASE-LX, and 1000BASE-CX) that are used for a universal link encoding and can be 1000mb/s transmitted. 1000BASE-SX, 1000BASE-LX interface using optical fiber as a medium, the farthest transmission distance of up to 5000 meters, so can be used in buildings or campus backbone network. The 1000BASE-CX interface is plan

STM32 practical application (I) -- 1602 Bluetooth Clock 1 LCD Display Test, 20171602Preface After studying for so long from 51 to ikef4, I finally got a clue. Now I have learned the basic usage of GPIO, interrupt, timer, and watchdog, so I want to see if I can do something, I just want to review my recent knowledge. Last semester, I designed a single-chip microcomputer course with a clock that can be used for Bluetooth, button calibration, and tempera

Introduction to DMA and Direct Memory Access for STM32, dmastm32 The first time I came into contact with DMA, I learned the arm9-bare-board program at school. I thought it was almost two years later. Now let's take a look at the dma of the STM32 platform. With the support of the standard peripheral library, the DMA programming of the STM32 is very simple, but it

First , the background as described earlier, the advantage of using standard library functions is that it can be developed quickly, without going to the data sheet, with a cautious configuration of oneComplicated registers, because these work stmicroelectronics has found some top engineers to help you, and masterpieces are both library functions. Of course, some codeThe library function cannot be used, given the low power consumption or the need for a very small ROM, which is usually said,"highl

I believe many people want to upgrade the firmware, just like the ones on the mobile phone, if the firmware is not enabled. The following describes how to implement the bootload function. Some time ago, I had a project on the bootload design. So I carefully studied it. I used to use the official stm32 and did not go into details. After completing this operation, I found some problems with the official version. For example, during the ymodem transmis

Embedded Linux and 51/430/stm32 Embedded development of the Difference and Association summary: Microcontroller series: 8051, MSP 430, STM32 f0-3 (ARM cortext m0-m3 series), etc.The main feature is that there is no memory management unit, no Linux operating system with virtual memory, only bare-metal programs or a Ucos class of real-time operating systems can be run. The main work is peripheral driver devel

Ethernet technology has entered the 10G era. Ethernet is no longer just a LAN technology, but a Layer 2 bearer technology from desktop to core, from enterprises to telecom operators, from LAN to Internet backbone. As a result, the 10-ge Ethernet switch, as the core of the network, is facing unprecedented challenges. In the past, all the Internet routes, ACLs, sFl

Data Link layer for EthernetAt the data-link layer, Ethernet is responsible for Ethernet addressing, which is often referred to as hardware addressing or MAC addressing. Ethernet is also responsible for encapsulating packets from the network layer into frames.Ethernet AddressingEthernet addressing uses the MAC (media access control) address that is cured in each

The Ethernet channel (ethernetchannel) increases the link bandwidth by bundling multiple Ethernet links, and runs a mechanism to bundle multiple Ethernet ports into a single logical link. The Ethernet channel can be bundled with up to 8 physical links, where the physical link can be twisted or fiber connected.

What is a vswitch port? What is the role of the vswitch port? Vswitches cannot play their role in optimizing network performance. After reading this article, you will surely have a lot of GAINS. I hope this article will teach you more. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traffic analysis, and intru

The most important function of a vswitch is to speed up the fast data forwarding in a large local area network. The routing function is also used for this purpose, so the switch port issue is also very important, it is really not easy to set a vswitch port. In an Ethernet Switching environment, communication between two workstations is usually not intercepted by a third party. In some cases, we may need such listeners, such as protocol analysis, traff

Ethernet access technology is still quite common, and it is also a type of access technology that deserves our research. So I have studied the characteristics and advantages of the Ethernet access technology, and I will share it with you here, I hope it will be useful to you. With the rapid development of the Internet, IP has dominated various terminal applications, and no one will doubt the mainstream netw
