I am writing TCP connection using W5500 with STM32 with bare hands (no libraries)
So far I have configured W5500 to be both, client and server. I have connection but I cannot figure out how to read or send data.
Yes I have read datasheet but it fails hard for me to make sense out of it.
My current problem is that, I connect to a server (wireshark confirms connection), then server sends me some string (I can see its size from W5500 and its correct) but I have no goddamn idea how to actually read the string.
Yes I have read about RX write pointer and RX read pointers but have no idea how to use.
datasheet mentions RX Buffer but I cannot find it anywhere.
Please help me
