That was my plan - use position-interpolated.. 100 counts is barely enough
for smooth motion.

Actually, the missing-tooth scheme takes a different opinion. Each hole
corresponds to 1/

This may be a bit wild but use pll and trigger when the expected pulse
doesn't appear. Maybe a bit far out of the box.
Basically the reverse of synchronous detection.

I have a optical encoder from a mouse running on an emco encoder wheel (100
holes). I cut out the metal between 2 holes. I think that would be
considered one missing tooth... I have the encoder scale set to 100 and
the missing tooth set to 1
I have a little comp that sets the index enable to tr
17 matches
