W5500 and matter protocol are not compatible?
Hi,I'm using W5500 with esp32 (IDE Arduino, ethernet library) and matter library on my iot device.The commissioning with Home Assistant is ok, i can manage my device normally.Also after poweroff-poweron for a few seconds the device is available on Home Assistant.But if i poweroff the device for over 2 minutes and Home Assistant detect the device as unavailable, after poweron the device don't recon…

Arduino RP2040 Nano + W5500: max 10 kbits/sec outbound?
We have been successfully sending UDP messages at a sustained rate of 100 Hz (100 messages/second) from an arduino RP2040 Nano over a wifi connection. The UDP message payload is 33 bytes, so including 8 bytes of UDP header and 20 bytes of IP header our outbound data rate is: (20 bytes IP hdr + 8 bytes UDP hdr + 33 bytes UDP payload) * 100 msg/sec = 6100 bytes/sec, or roughly 60,000 bits/sec (60 kb…

Faults in W5500-based prototype board
I’m doing a development based on the W5500 for industrial environment, which is an update of the same design based on the W5100. The previous board based on the W5100 has been running 24/7 for more than two years without any incident, while the prototype of the new version did not get it to work properly for more than a week or week and a half, and we are nearing the deadline of the design phase.…

W5500 Ethernet shield spi dma rx 데이터 수신이 안됩니다.
안녕하세요. 현재 stm32h7 mcu 보드에 W5500 이더넷쉴드를 연결하여 통신기능 테스트중입니다. 기존에 5100S 이더넷 쉴드 모듈을 이용하여 개발하다 여러가지 문제로 W5500 이더넷쉴드 모듈로 변경하였습니다. 기존 W5100S 모듈에서 SPI 통신기능을 DMA를 활성화해서 데이터 송수신이 정상적으로 동작하는것을 확인하였고… 동일 MCU 보드에 W5500 이더넷쉴드만 변경하였습니다. 위즈넷 IO Library는 gitHub에서 최근 버전으로 다운받아서 적용했습니다. 증상은 위에 말씀드린대로 SPI를 DMA모드로 설정 시 TX 데이터는 전송되지만 RX 데이터가 항상 0으로 읽힙니다. SPI 설정 시 TX만 DMA를 설정하고 RX는 DMA 설정을 하지 않으면 정상 동작합니다. SPI 클럭은 25Mhz를…

Hi all, I developed two different cards AtMega2560 based, using ethernet2 TCP/IP library. Both cards use W5500 ethernet shields. We are experiencing some random W5500 reset. After 3-4 days or some, the chip stops responding. We have a serial interface with a CLI and we discovered that all the W5500 parameters come to the default value (IP=0.0.0.0/subnet=255.255.255.255 and so on). The W5500 rst li…

[W5500, W7500] W5500 Ethernet shield 사용 관련
W5500을 TI DSP를 사용하는 보드에 적용하려고 WIZnet 테스트 보드로 공부하는 중입니다.

W5500 board fails on Mega 2560
I’ve spent the last 3 days trying to get a W5500 Ethernet Shield to work on a Mega 2560 and got nowhere. I started a thread on the Arduino forum asking for help and got a good number of replies but am still unable to get the board to work. Rather than copy paste everything from the Arduino forum into this post i ask that you have a read of my thread. Two different W5500 Ethernet Shields fail 100%…

SPI connecting problem W5500 Ethernet Shield
Greetings! I am getting wrong info from Ethernet Shield W5500. In datasheet it is said that the content of VersionR is always 0x04, but I’m getting 0x03. Also I have found in datasheet that the SPI speed varies in the range of 33.3 - 80 MHz. I’m using a board based on ATmega2560 with external crystall oscillator of 14.7456 MHz. Maybe the problem is in the wrong speed? But I have seen an example of…
