I just want to know if there is anyone who had debugged the printf function using a modified putchar.c file. 
This is becasue my project which uses my own putchar.c file added to my project was compiled without any error nor warning.

&lt;br /&gt;
That description is useless.  One of the oldest well-known facts about computer is that they dont&amp;#39; &amp;quot;understanding&amp;quot; anything.  Never have, and there&amp;#39;s doubt they ever will.  Code files understand even less.&lt;br /&gt;
&lt;br /&gt;
So: what did you actually do, and how did it fail to work out?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Bebugging the printf using uVision</title><link>https://community.arm.com/thread/73948?ContentTypeID=1</link><pubDate>Fri, 07 Apr 2006 07:25:27 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:a9dc62ce-1cf9-4d3d-809f-ee09286a269f</guid><dc:creator>Omar Espinosa</dc:creator><description>&lt;p&gt;Hi Hans,&lt;br /&gt;
Thank you so much.  It really works.&lt;br /&gt;
&lt;br /&gt;
Thanks to that, I realized I have a problem in my putchar() function.  I want to switch the printf between LCD and UART by a varible I call it: putchar_target.&lt;br /&gt;
I defined the varible in putchar file but my code file does not understand it.  I did in my main file, but the putchar() does not understand.  Where should I declare the putchar_target in order to the main code file and putchar file understand it?&lt;br /&gt;
&lt;br /&gt;
