<<CODE>>
DigitalOut myled(LED2); 
Serial pc(USBTX,USBRX); 
int main()
 { 
while(1) 
{ 
 unsigned i;  
 myled = 0; 
 pc.printf("hello world ");
  for(i = 0; i < 10; i++) 
 pc.printf("%d\n", i );     <-- use pc before printf to display it through terraterm !
 ....

 wait(1); 
 myled = 1; 
 wait(1); 
 } 
}
<</CODE>>

and please use "<<code>> your code <</code>>" to make sources more readable...

Accepted Answer

one minor detail: Since i is an unsigned int the printf should be %u not %d. For small numbers it won't make any difference but for large numbers (over about 2 billion on a 32 bit system) it will.
