Even if there is a date, I hope 1.3.0 will be
released before the end of the year. Else, you can get the last CVS
HEAD.
First, which features do you need ? Do you have
disable most of options you don't use?

There is some indications in init.c , in the
last CVS HEAD. Take a look on lwip_sanity_check and on
previous preprocessor checkings.

Hi
all.
Can someone help me to understand options in opt.h
(LWIPopt.h) which change memory usage?
what are limits for each
option? (for example NOT LESS THAN...)
How each option is connected
to others? (for example: options for sequential API and options for tcp
and udp connections... )
can i change pbuf options?
(PBUF_POOL_BUFSIZE..... )
in particular, i want to understand how
reduce the following variables:
- ram
-
memp_memory
- pbuf_pool_memory
depending on number of
simultanely connections (TCP, TCP LISTENER, UDP) (i have to use socket
for apllication porting reasons)
Correct me if i'm
wrong:
the total memory depends on 3 things:
- memory for
low level driver, where MAC layer puts ethernet frames
- memory for
LWIP (the above discussion)
- memory for application task, which use
sequential API and needs a owner buffers
is it
true?
PLEASE HELP ME!
i'm working on an example which
use:
- LWIP (1.1.1.. but i will update to 1.2.0) (ported from GNU to
IAR)
- FRERTOS FOR ARM7 (lpc2368 microcontroller)
- lpc2368 EMAC
driver
i'm having a lot of problem, and i have to reduce memory
usage...
and at the last (....) i have to understand how to use
lwip!!!
Bye,
Piero
