10 years later and I'm still loving my basic Saleae logic probe. It was invaluable to help me figure out what's going on with these encoders.

- noticed jitter on 2nd circuit on chinesium double encoder when I move other shaft,
- spent all day going through my code, turned out the 2nd channel is also dropping pulses.

I can't imagine life without it (top pair at PIC, bottom at encoder pins).

Pulses are inversed because I use a 74HC14 after Bourns debounce to clear up signal.
