Hi.

 

Your problem is most likely that the compiler optimizes the line
while(!(UCSRA&(1<<UDRE))); away.

 

Try this instead.

 

while(condition=true)
{
  while(!(UCSRA&(1<<UDRE)))

  { 

  #asm("nop");               // or how ever your compiler accesses assembly
inside C.

  }
UDR=data
}

 

Regards 

 

Lasse Madsen
