> If you need faster pulses than that, try a PWM channel - I think you can > get a pulse per cycle that way, with no software overhead once started.

You can get two pulses per instruction cycle, or frequency of Fosc/2. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
