Re: [lpc2000] printf

2005-04-01 by Leonardo Santos

Could you elaborate on that? I'm using GCC 3.4.3 + newlib 1.13 I downloaded 
from http://rod.info/arm.html. I've been able to compile FreeRTOS for a 
LPC2106 target and played a little with it. But I really miss the printf 
function. I think this question might be off topic, but if I could get some 
pointers, I'd be very grateful.

Lesson:
Never take stdio.h for granted!

Thanks!
