Hello.
While implementing mcu and tcp/ip client communication with w5500-based Ethernet shield, there was a problem that the chip version could not be read properly.
Look at the w5500 datasheet, it is normal to get 0x04 as the version value, but I get 0x00
But the board is assigned an ip.
If I give the command ping 192.168.0.75 in cmd it will respond.
Also, communication programs such as Hercules or Easytum cannot be used to connect.
The io library is using version 1.0.2, and it has been confirmed that there is no problem with the hardware connection.
Which part is the problem?
And… Unfortunately, I don’t have an oscilloscope…
Below are the hardware specifications. The code is also attached.
Ethernet shield: https://www.devicemart.co.kr/goods/view?no=34412
mcu: NUCLEO-F411RE | Mbed
If there is a Korean developer, please reply in Korean…
Also, since this is my first time using the forum, please understand that I have edited the post several times.
