I already posted that, but it was while trying (unfortunately) to
re-suscribe to the PICLIST ; so I don't know if this message had been
correctly sent. A thousand of excuses if you already read it (but I got
no answer :-((

I have uploaded some timing based 12c508 code (actually auto-sync RS-232) code
with some discussion about the timer load/reload stuff.

http://www.iversoft.com/piclist/code.html

Look for file serial10.zip.  This allows 'accurate' measuring of a start bit
pulse +/- a few cycles at about 50 uS. (Simulated only :-)  A little extra code
should give you milli-second resolution...

Good luck...

Ralph

               Thanks Ralph,

       I will have a look to your program (did you try it in "real world" now
?)

But I recall you this is only 1 part of my 2 problems that are :

1) Measure input pulse
2) While doing output PWM ...

I thought of a main program polling alternatively between 2 "main
subroutines" : 1 for In and 1 for Out.
But, for sure, I will loose accuracy (that should not too important for
me since 1/64 ms should be enough)

Thanks and Bye

Jean-Yves
