Re: PWM's and UART

2005-04-25 by bobtransformer

I have a similar interest.  I'd like to use both uarts and
at least 2 PWM outputs that are 2 channels away from
each other (for 2 phase 180 degree out of phase pwm
drive).  I believe that I am  able to
use pwm 3 and 5 (or was it 1 and 5?) or something like that.
I hear the words "I/O map" being used around the LPC
circles but that may be just for setting pins for I or O or the 
special dedicated functions assigned to those pins.  I haven't gotten 
that far yet.
