Re-written the machine code for initialisation in C. I suspect, but have not
checked, that it is something to do with the value I set in CCP1CON. Will
have to re-run my ealier code for 16f628 and try tweeking that parameter.

Yes, I've had circuits that worked in the simulator but did nothing on the
board. Usually config bit problems.
Just running it against gpsim at the moment. Not built the board yet. Would
be a good plan to do so just to check the PWM bit. Next thing to do is to
get a to d working, however, I have had that working already on a 16f877, so
I hopefully am ahead of the game a little there.
Thanks for your help.
