Trying to enable debugging for IGMP within lwip and having some issues. I have os_printf working and the following defines in lwipopts.h, but not getting anything. Any idea what I'm missing?
#define LWIP_DEBUG

ugh... well, os_printf is working from sketch, but not from within igmp.c

silly me, thought Arduino compiled lwip each time. Ok, compiling it myself now. having issues tracking down where ETS_ASSERT comes from however

does anyone know what this circuit is for? is it level-shifting?
err, that seems like the wrong photo
ah, maybe it inverts the signal so the serial gets a 1 when tx is 0
