Have a look at the uart.c file in the example folder (C:\WinAVR-20081205\doc\avr-libc\examples\stdiodemo) The only thing I can think of of is that the clock is not correct (which you have verified) OR the compiler THINKS is something else. Maybe the lack of UL in your #define F_CPU 4000000UL?? Regards John Samperi ******************************************************** Ampertronics Pty.
