Wiat let me correct that... I just looked at the schematic, there is not a pull up on PortA.5. Sorry about that, I did not do the hardware, I am just doing the programming.


I have a 3uS pause after the falling edge (was 1uS, but Alain correct me on that already)

Thanks for all your help so far guys...

I am still learning this digital stuff, and have been slowly making my way up the hill.
