Hi,
I think that CCP1 defaults to RB3 and that you, as you say, has to reconfig it to have it on RB0 instead.

Open 16F88.inc file located in the PBP folder and change the CONFIG line to:

__config _CONFIG1, _HS_OSC & _WDT_ON & _LVP_OFF & _CP_OFF & _CCP1_RB0

Note that there are two lines, one (the one I showed above) if you use MPASM and another if you use PM and they differ slightly in the format used but you'll get the idea.

Just remember that once you've edited the file it stays that way and if you forget about it you'll scratch your head the next time you're using the F88 and the CCP module doesn't work on RB3.... ;-)
