Hi all. 

Could anyone explane me what different between UART1 and UART0 (except 
modem control register in UART1).

I can't understant NOTHING!
Two equal initialization. Equal ISR but when I try to work with UART1, 
system hand-up. UART0 working absolutely normal. Exactly like in PDF, 
without ANY problem.

Hi,
 
Could you please send me the code for UART0.
 
Here i am facing some problem with UART0.
 
I am unable to send any charector to Hyper Terminal..
 
Thanks in advance.

There are examples in the files download area.  The newlib-lpc library ( 
http://www.aeolusdevelopment.com ) has drivers for both UARTS both polled 
and interrupt driven.

I've been having a terrible time with getting the interrupts working
on the LPC2294 using the Keils tools.  The code being created seems
fine, but if I try and enable the interrupts, sometimes it will work,
sometimes they are ignored and sometimes the processor just locks up.
 I generally have to spend an hour or so trying to figure out what
order to initilize things in before they work.

I can't use this interrupt by many reason. The main is Ineed a nested 
interrupts. 

And I think that I have a problem with them.

They would still be a way to verify your own approach didn't leave anything 
out though.


>And I think that I have a problem with them.

Which raises two questions
   Have you verified that you have working non-nested interrupts?  Always 
get the simpler case to work first.
   Are you absolutely certain you need nested interrupts?

I strongly suspect that nested interrupts will require an assembly language 
shim.  I would advise using such a shim even for standard interrupts but 
not everyone shares my paranoia on that :)
