Hello group Happy
New Year!
Im still going
down the path of using NO_SYS=1 in my application, but Im beginning to think
because Im in apparently less-traveled territory here that this may turn out
to be a bad idea.
The question is,
are the APIs functional with NO_SYS=1? netconn_accept doesnt block and
so I wonder if this is wrong or if the APIs arent meant for no OS. I
can run in a loop calling functions as needed, based on their timeout
intervals, and DHCP finds an IP address and then I can Ping
successfully. So lwIP is otherwise functional as Ive implemented it
with NO_SYS=1.
If NO_SYS=1 isnt a
good idea, what can be done for a minimal lwIP single threaded application to
emulate an OS? I now can periodically call the lwIP timing functions
(tcp_tmr, arp_timer, ip_reass_tmr, dhcp_fine_tmr, and dhcp_coarse_tmr) as
needed watching an mS free running counter.
Thank
you,
Bill
