About the W5500 TCP send and receive data

TCP/IP Chip W5500

Dear all:
I am running TCP-Client on TMS320F28335.W5500 as the client.I was using the network debugging Assistant to send data to the W5500.Suddenly I wondered,the data sent from the network debugging assistant, or received by the W5500, which variable should I look at in the underlying program?Or can you only use network analysis software such as wireshark to capture data packets and see the detailed data inside?
Looking forward to your reply from relevant engineers as soon as possible.
Thanks

use the recv() function in socket.h to read the data from RX register to your software buffer.

Dear Vien_Huy_Nguyen:
I want to know,When designing the hardware, does the reset pin of the W5500 chip have to be connected to the MCU? Can you not use the reset pin of the W5500? Only four lines of SPI are used. What’s the effect of not using the reset pin of the W5500 chip? Please answer.
Thanks

You have to reset the chip at least once at startup. So yes, you need to connect the RST pin to the MCU.
