Re: [lpc2000] Problems with UART1 on LPC2132

2005-06-20 by Peter Jakacki

Oh, you can transmit a 0 ok, it's just that the PC may strip NULs (0's) 
from the input stream. It just comes back down to what software you are 
using to receive. But since I don't know what you are using I can't help. :)

BTW, try transmiting 0's from the PC back to the PC to test that end. 
Elimination is the 1st part of debugging.
