I'm creating a silly little thing that has stepper motors attached. They need to run pre-configured/timed sequences. For example, a motor goes CW 60 steps in 1 second, then CW 30 steps in 2 seconds, then repeats. There are 3 motors, each with it's own sequence.

Would it be best to have each motor on it's own interrupt, all three on one interrupt, or not use interrupts at all?

I'm using a PIC18F4550, as far as I can tell, there are enough interrupts available.
