Re: [lwip-users] How to calculate the memory size used by lwIP?

[PHAM ANH THIEN]

the total memory size of lwIP is MEM_SIZE plus memp_memory. memp_memory include many types memory which define in lwip/memp_std.h, they could be MEMP_RAW_PCP, MEMP_UDP_PCB, MEMP_TCP_PCB... it depends LWIP_XXX you define in your lwipopt.h. So how to calculate each type memory, for example with MEMP_PBUF_POOL

LWIP_PBUF_MEMPOOL(PBUF_POOL, PBUF_POOL_SIZE,           PBUF_POOL_BUFSIZE,             "PBUF_POOL")

memory size of it is:  PBUF_POOL_SIZE *  PBUF_POOL_BUFSIZE.

Hi All,

We set MEM_SIZE in lwipopts.h, but how much memory is enough for lwIP?

Thanks for your help!
