W5300 get IP from DHCP server

Question

Hello, I had very hard time while working with W5300. Originaly i use STM32F4 in SRAM interface. I downloaded example for W5300. Can read id no problem, so my hardware works. Now program itself does not want to work, i have no idea why, it does open socked and send connect, no problem, but i just can’t get any data flow. My question is this. How based on W5300_Drv_V1.2.6 driver get IP address from DHCP server ? I am too new to all LAN stuff, maybe some one can help me out. And if you do, can you do that based on V1.2.6 driver ? Or maybe some on has complete working example for STM32F4 in FMC mode how to make throughput test ? Many thanks !

Hello, Sorry for the late reply. Initialize the DHCP using DHCP_init() call callback function using reg_dhcp_cbfunc() loop the dhcp_run() until the return value of dhcp_run() will be DHCP_IP_LEASED. If the return value is DHCP_IP_FAILED, you can process that is the timeout by counting. github.com/Wiznet/W5500_EVB/tre … hcp_client You can download the dhcp example from the link above. Although it is for the W5500evb board, I think it will help you. Thank you
