sprintf输出到哪里看？

AT91RM9200的官方例程里有两个函数<br />AT91F_DBGU_Printk<br />sprintf<br />其中前一个是输出到调试串口PA30,PA31&nbsp;DEBUG,接个超级终端就可以看到<br />sprintf怎么看？<br />如：AT91F_DBGU_Printk(&quot;

-I-&nbsp;================&nbsp;IP&nbsp;HEADER&nbsp;======================
&quot;);<br />&nbsp;&nbsp;&nbsp;&nbsp;sprintf(MsgBuffer,&nbsp;&quot;
&nbsp;IP&nbsp;Version&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=&nbsp;v.%d&quot;,pIpHeader-&gtip_hl_v&nbsp;&&nbsp;0x0F);<br />&nbsp;&nbsp;&nbsp;&nbsp;AT91F_DBGU_Printk(MsgBuffer);<br /><br />&nbsp;&nbsp;&nbsp;&nbsp;sprintf(MsgBuffer,&nbsp;&quot;
&nbsp;Header&nbsp;Length&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=&nbsp;%d&quot;,(pIpHeader-&gtip_hl_v&nbsp;&&nbsp;0xF0)&nbsp;&gt&gt&nbsp;2);<br />&nbsp;&nbsp;&nbsp;&nbsp;AT91F_DBGU_Printk(MsgBuffer);<br />

  

知道了要和AT91F_DBGU_Printk(MsgBuffer);配合使用，SPRINTF只完成格式转换
