I've just switched over from using the old PIC16F84 to the PIC16F628. I = use PicBasic Pro for all my programs. =20 I just want to know if my thinking is correct... Since the 16F628 has = hardware PWM, is it possible for me to write a program in Basic where I = can output PWM pulses on several pins simultaneously while at the same = time listening for serial data on another pin? =20 i.e. Can I set the output pins and let the hardware maintain the PWM = pulses indefinitely without having to do any looping? Thanks for any advice. -Dan -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
