When you post code, you need to enclose it within <pre> and </pre> HTML tags - so that your formatting is preserved.

For example:

<pre>
void SPI_out(int send,int l_add,int u_add) 
{ 
   DPH = u_add; 
   DPL = l_add; 
   SPDR = send; 
   while(SPSR != 0x80); 
}
</pre>

(Of course, when you do it, you won't actually see the <pre> and </pre> tags!)

Use the 'Preview' button to check before you press the 'Post' button.
