I am proposoing to put NPN transistor to invert the waveform?
If cannot then fine.

I'm thinking the problem overall is the fact that you've got one resistor for current limiting for 2 LEDs. If you pull either pin low and you're measuring your signal on the LED side of the resistor, it won't matter which pin gets pulled low, they will probably both read low at back side of the LED (the connection nearest to the resistor).
What do you get if you 'scope the actual pins themselves, right at the PIC with nothing else connected?
Good suggestions, Adam. But, I have done all those things (except make the time longer). Look at post#15, why is that waveform the same as post#1?
Thanks fellas, I started a new thread and got the answer: CMCON=7. I have not figured out why that works, maybe it is just one of those things I was not meant to know.
Hey Russ,
You're doing a great job with N&V!
Keep it up!
