Hello I have used iolibrary and example from here
to setup my ATSAMD21 curiosity nano and ETH WIZ clck. SAMD21/W5500 configures and connects to my pc. I can send and receive data.
When I was trying to see what can I achieve max with data rates I saw that while constantly transmitting I can not receive data sent from hercules sometimes.
I constantly transmit loop count in main as data. Which starts from 1 and increment whenever it loops.
I randomly send 1 byte of data which is character ‘0’ and It should toggle on board led. Onboard LED does not toggle sometimes…
