#define MEMP_NUM_API_MSG MEMP_NUM_TCPIP_MSG_API |
MEMP_NUM_API_MSG: the number of concurrently active calls to various socket, netconn, and tcpip functions
#define MEMP_NUM_ARP_QUEUE 30 |
MEMP_NUM_ARP_QUEUE: the number of simultaneously queued outgoing packets (pbufs) that are waiting for an ARP request (to resolve their destination address) to finish. (requires the ARP_QUEUEING option)
#define MEMP_NUM_DNS_API_MSG MEMP_NUM_TCPIP_MSG_API |
MEMP_NUM_DNS_API_MSG: the number of concurrently active calls to netconn_gethostbyname
#define MEMP_NUM_FRAG_PBUF 15 |
MEMP_NUM_FRAG_PBUF: the number of IP fragments simultaneously sent (fragments, not whole packets!). This is only used with LWIP_NETIF_TX_SINGLE_PBUF==0 and only has to be > 1 with DMA-enabled MACs where the packet is not yet sent when netif->output returns.
#define MEMP_NUM_IGMP_GROUP 8 |
MEMP_NUM_IGMP_GROUP: The number of multicast groups whose network interfaces can be members at the same time (one per netif - allsystems group -, plus one per netif membership). (requires the LWIP_IGMP option)
#define MEMP_NUM_LOCALHOSTLIST 1 |
MEMP_NUM_LOCALHOSTLIST: the number of host entries in the local host list if DNS_LOCAL_HOSTLIST_IS_DYNAMIC==1.
#define MEMP_NUM_NETBUF 2 |
MEMP_NUM_NETBUF: the number of struct netbufs. (only needed if you use the sequential API, like api_lib.c)
#define MEMP_NUM_NETCONN 4 |
MEMP_NUM_NETCONN: the number of struct netconns. (only needed if you use the sequential API, like api_lib.c)
#define MEMP_NUM_NETDB 1 |
MEMP_NUM_NETDB: the number of concurrently running lwip_addrinfo() calls (before freeing the corresponding memory using lwip_freeaddrinfo()).
#define MEMP_NUM_NETIFAPI_MSG MEMP_NUM_TCPIP_MSG_API |
MEMP_NUM_NETIFAPI_MSG: the number of concurrently active calls to the netifapi functions
#define MEMP_NUM_PBUF 16 |
MEMP_NUM_PBUF: the number of memp struct pbufs (used for PBUF_ROM and PBUF_REF). If the application sends a lot of data out of ROM (or other static memory), this should be set high.
#define MEMP_NUM_RAW_PCB 4 |
MEMP_NUM_RAW_PCB: Number of raw connection PCBs (requires the LWIP_RAW option)
#define MEMP_NUM_REASSDATA 5 |
MEMP_NUM_REASSDATA: the number of IP packets simultaneously queued for reassembly (whole packets, not fragments!)
#define MEMP_NUM_SOCKET_SETGETSOCKOPT_DATA MEMP_NUM_TCPIP_MSG_API |
MEMP_NUM_SOCKET_SETGETSOCKOPT_DATA: the number of concurrently active calls to getsockopt/setsockopt
#define MEMP_NUM_SYS_TIMEOUT (LWIP_TCP + IP_REASSEMBLY + LWIP_ARP + (2*LWIP_DHCP) + LWIP_AUTOIP + LWIP_IGMP + LWIP_DNS + (PPP_SUPPORT*6*MEMP_NUM_PPP_PCB) + (LWIP_IPV6 ? (1 + LWIP_IPV6_REASS + LWIP_IPV6_MLD) : 0)) |
MEMP_NUM_SYS_TIMEOUT: the number of simultaneously active timeouts. The default number of timeouts is calculated here for all enabled modules. The formula expects settings to be either '0' or '1'.
#define MEMP_NUM_TCP_PCB 5 |
MEMP_NUM_TCP_PCB: the number of simultaneously active TCP connections. (requires the LWIP_TCP option)
#define MEMP_NUM_TCP_PCB_LISTEN 8 |
MEMP_NUM_TCP_PCB_LISTEN: the number of listening TCP connections. (requires the LWIP_TCP option)
#define MEMP_NUM_TCP_SEG 16 |
MEMP_NUM_TCP_SEG: the number of simultaneously queued TCP segments. (requires the LWIP_TCP option)
#define MEMP_NUM_TCPIP_MSG_API 8 |
MEMP_NUM_TCPIP_MSG_API: the number of struct tcpip_msg, which are used for callback/timeout API communication. (only needed if you use tcpip.c)
#define MEMP_NUM_TCPIP_MSG_INPKT 8 |
MEMP_NUM_TCPIP_MSG_INPKT: the number of struct tcpip_msg, which are used for incoming packets. (only needed if you use tcpip.c)
#define MEMP_NUM_UDP_PCB 4 |
MEMP_NUM_UDP_PCB: the number of UDP protocol control blocks. One per active UDP "connection". (requires the LWIP_UDP option)
#define PBUF_POOL_SIZE 16 |
PBUF_POOL_SIZE: the number of buffers in the pbuf pool.
