Detailed Description
Macro Definition Documentation
◆ DHCP_DOES_ARP_CHECK
DHCP_DOES_ARP_CHECK==1: Do an ARP check on the offered address.
◆ LWIP_DHCP
| #define LWIP_DHCP 0 |
LWIP_DHCP==1: Enable DHCP module.
◆ LWIP_DHCP_BOOTP_FILE
| #define LWIP_DHCP_BOOTP_FILE 0 |
LWIP_DHCP_BOOTP_FILE==1: Store offered_si_addr and boot_file_name.
◆ LWIP_DHCP_GET_NTP_SRV
| #define LWIP_DHCP_GET_NTP_SRV 0 |
LWIP_DHCP_GETS_NTP==1: Request NTP servers with discover/select. For each response packet, an callback is called, which has to be provided by the port: void dhcp_set_ntp_servers(u8_t num_ntp_servers, ip_addr_t* ntp_server_addrs);
◆ LWIP_DHCP_MAX_DNS_SERVERS
| #define LWIP_DHCP_MAX_DNS_SERVERS DNS_MAX_SERVERS |
LWIP_DHCP_MAX_DNS_SERVERS > 0: Request DNS servers with discover/select. DNS servers received in the response are passed to DNS via dns_setserver() (up to the maximum limit defined here).
◆ LWIP_DHCP_MAX_NTP_SERVERS
| #define LWIP_DHCP_MAX_NTP_SERVERS 1 |
The maximum of NTP servers requested
