ethernet

I need to design an interface that will run at 1Gbps that someone else will be designing and testing. If I specify that this interface as requiring to adhere to the 100Base-T standard, is that sufficient? In other words, do I need to specify line rate vs data rate or what protocol to use or...

This is the magnetics connection in my design. This PCB circuitry has been tested and working individually, but when I connect two or more of the same PCB hardware to an ethernet switch, the subsequent hardware would not be able get physical link over ethernet, only the first one connected would...

I want to send a GET request to a server, so I connected the microcontroller (STM32) with an Ethernet module, as the microcontroller does not have a built-in Ethernet feature. I am using these two libraries: #include "stm32f4xx_hal_uart.h" and #include "stm32f4xx_hal.h". My GET string is: char...

Hi, I am quite new to ESP32 programming. I have a task to establish the TCP communication via ESP and PC (PC wont send anything to the ESP, It will be one way communication from ESP to PC). I am using the ESP Ethernet KIT (ESP32 WROVER E) I took an existing basic ethernet example form the ESP...

Ethernet MAC tablosu nasıl sıfırlanır. Örneğin 300 saniye dolduğunda MAC tablosunu sıfırlamak istiyorum. 1-) Süre MAC tablosuna yazılan ilk adresle başlayıp 300 saniye dolduğunda tüm mac tablosunu sıfırlıyor mu? 2-) MAC tablosuna yazılan her adres için süre ayrı ayrı ölçülür ve sadece 300...

Hi, I'm planning to use Intel Stratix 10s inbuilt 10G Hard IP. My questions as follows, 1. Is it rite that we can't use copper ethernet cable for speed greater than 10G, we have to use optical cable only? 2. Optical transceiver - Female connector & optical fiber connector - male which mates...

Hi, I'm trying to create a little ethernet board and I seemingly can't get it to communicate with an ESP32. I'm posting in this thread first as I suspect it's due to the design rather than the ESP32 ethernet library(could be). The design is based on the W5500 as its the chip LCSC has the most...

Hello all, I have an issue regarding ethernet with esp32, So i have got designed a hardware with esp32 and dp83848 phy for ethernet connection. The problem is i dont get Link Up from phy. I am running esp32 example code PHY reset pin is 32. this is log output from board, it just stops at...

Hi, I am designing a board that utilizes an NXP LS1046a processor and multiple Kintex Ultrascale FPGAs. The plan is to connect the processors up to the three FPGAs via the 1Gbe links. Since they are all on the same board, the plan was to try and connect them up without using any PHY devices...

Hi, Using a ENC28j60 with a cc1352p1 microcontroller and the lwIP stack. I'm trying to ping my device after manually assigning it an IP, and I can ping it and get a response when the number of bytes in the ping is < 244 bytes. So if I do >> ping 192.168.1.10 I get: 64 bytes from...

Hello iam trying to connect 2 MSP432E mcu's to one ethernet port, iam thinking a 3 port ethernet switch would work or a optical isolator would work.I was curious if other ways exists such as just being able to connect both Mcu's ethernet traces to each other.any iput is appreciated thanks

I am using an ENC28J60 Rev 7 (REVID = 0x06) with a TI CC1352P microcontroller. Trying to transmit and receive ethernet packets between the MCU and my computer. I was able to transmit packets from my MCU and see them in Wireshark, I could see the content of the message correctly. I am doing a...
