Question

STM32F4 + LAN8720

Hi all!

I'm trying to send a page to the browser using a microcontroller. I use instructions and code from YouTube. I generate fsdata.c. I connect LAN8720 with a cable directly to the computer. As a result, the ping passes, but the site is not displayed at the same address (http://192.168.77.6).

Why might the page not be displayed?

I watched a lot of videos with examples of setting up STM32 for a web server and noticed that the network settings on the computer were not discussed anywhere. That is, for example, with DHCP, my network scanners do not see the device at all and it does not ping. If you specify the address programmed into the controller in the IPv4 settings, then a ping will respond to this address, but the site page will still not be displayed. What should be the network settings on the computer?
