I am using the callback API with the LWIP
stack. Currently I have a function that calls the timers (etharp_tmr,
tcp_slowtmr, tcp_fasttmr, etc.) and the processing of received packets. I
call this function in the main non-IRQ loop. However, I am finding
that in some cases I can not call this function frequently enough to keep up
with the packets and/or timers. I was thinking of setting up a low
priority IRQ to simply call this function about every 100ms or so to process the
timers and received packets. My question is this, if I am also trying to
set up calls to tcp_write at the non-IRQ level will cause problems for the stack
to run my processing function at the low level IRQ interrupt? Can this be
done and/or can it be done with certain precautions in doing so? Please
advise.
