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. bob --- In lpc2000@yahoogroups.com, amastella@v... wrote: > Hi, I'm studying LPC2214 for use on a new project.

In the Philips LPC User Manual, they say it's better use channels 2, 4 and 6 for double edge. It's not clear to me how can I make one motor accelerate while another one is in it maximum speed i. e. how can I maintain their independency. > > 2) If I use PWM channels 2, 4 and 6 I can't use UART1(PWM6 and UART1 use the same pin)...
