HI again.
I have now downloaded the AN696, and it's now
clear that Al was talking about high resolution
encoders (500 counts per revolution in the AN696).
I was thinking about those small encoders you
use as input devices on front panels. I can see that
these high res encoders easily can produce more
steps/sec then the PIC could handle with ease, and
the solution as described in the AN seems reasonable...

Sorry for the confusion...

Jan-Erik.
