(Reviving an old thread)

I now need to simplify this a bit and put this on a 8-pin PIC. I need 5 blinkies so I'd like to use a 12F629 (knowing GP3/MCLR is input only, I'll use GP0-GP5 and if nothing happens on GP3 then that's fine).

The code won't compile because of this part:

Code:
;-- setup CCP1 and Start Timer1 --
CCPR1   = CCPR1val          ; set compare value
CCP1CON = %00001011         ; compare mode, special event 
Timer1  = 0                 ; clear Timer1
T1CON.0 = 1                 ; start Timer1
These registers exist on a 16F690 (and others) but not 12F629. I had earlier tried a 12F683 (my go-to PIC) but the .inc file for it already has a define for CCPR1 so I'd have to comment out that line in the .inc file but that makes me a wee bit uncomfortable.

Is there a way to make this work on a 12F690 or 12F683? If not, is there another 8-pin PIC I could use? I need to be able to find SMT packages as the space where the PCB is going is extremely tight (I've never soldered SMTs before so that should be fun).

Here's the whole code:
