WebWith respect to lwIP, your main loop has two main jobs: poll your device driver to process received frames (the driver will pass them up to the lwIP stack using the input function you specified in netif_add) and periodically invoke the lwIP timer processing functions (etharp_tmr(), ip_reass_tmr(), tcp_tmr(), etc. -- the exact list depends on ...
