Hello everyone,
  I tried this yesterday and somehow missed the list, but I'll post with=20
more clues this time anyway. I'm using a 16F913 and having some trouble wit=
h=20
the PWM output on RC5. I had set it up and had it working, but since then=
=20
have added a lot of code and somewhere along the way the PWM broke without=
=20
me noticing it. I've tried several fixes so far that include re ordering th=
e=20
PWM module initialization code and rewriting the serial bit banged routines=
=20
that are on the same port so that they have no read-modify-write=20
instructions.. I guess I should tell you what I know first..=20
  The first thing is that I set the PWM period like this .... PR2 is 254,=
=20
Tosc =3D 2.5e^(-7) (4MHz clk), TMR2prescale =3D 16.. from the formula in th=
e=20
datasheet that gives:
 PWMperiod =3D 255*4*2.5e^(-7)*16 =3D .00408, so the PWM frequency should b=
e=20
1/.00408 =3D 245.1 Hz. When I measure the frequency on that pin though, I g=
et=20
around 9KHz. That is why I thought maybe my serial routines were causing th=
e=20
PWM bit to flip since they had RMW instructions in them.
 I've made sure of things like TRISC, 5 is clear and that I'm writing to th=
e=20
right registers in the right banks.. of course, there must be some mistake=
=20
otherwise this would be working.=20
 I'll be more than happy to post code, but I don't want to bog this message=
=20
down with it until I see that I get on the list and someone is curious.=20
Thanks a lot for any help anyone can provide!
 James
