On my own print with a lpc2132 mcu I can't seem to get the hello world example to work. I'm using the standard copy and my terminal settings are correct.
I've tryed using only sendchar but that doens't make a difference.
The PCB is working cause with other code it works without any problems.
That's a seriously premature conclusion. You ran two tests on your board. One (with that "other code") worked, the other (Hello world) didn't. How do conclude from these two results that the board works?
In particular, what makes you think your board's serial interface is working, given that you apparently never managed to get to send data over that interface?
in the other code I can't use the printf() statement but I can use sendchar()
Sigh. And why "can't" you use printf() in there?
