RyanN:
Thanks!I see that %S (capital S) is specific to avr C
Is there a resource which highlights some of these avr specific additions?
Wow...I had no idea that the avr library used %S for flash strings. And a respectable amount of googling still doesn't find any simple list of them.
The best I could find was the description of vfprintf() here -> avr-libc: <stdio.h>: Standard IO facilities
