Subject: debug printing inside an interrupt
From: sophana (jobarjo78_at_yahoo.fr)
Date: 2004-04-30


Hi all
 
I'm trying to implement a serial interrupt handler, but it does not seem
to work.
how can I print something to the screen from the interrupt handler to
see if it has been called?
I have a jukebox player.
I tried printf and fprintf but they are said to be undeclared.
fprintf is declared in sprintf.h but stderr is not declared... might not
work for the screen?
 
Thanks for your help
