Pls How can I make 16F877A use 15MHz Xtal

XT vs. HS. Check the datasheets
You have to reconfigure your PIC to run the 15mhz oscillator.

And check your PBP manual for the correct use of:
DEFINE OSC 15

geeeee !!! What a wonderful forum is has become these days ...

after all these years, I didn't know there was a DEFINE OSC 15 ...

12 or 16 only available ... too bad !!! ( Manual p. 170 ... )

but ... PBPIC libs can be modified, of course !!! ... or time related functions re-calculated ... isn't it ???

PS: Sorry Ozzie, but it will be VERY difficult to run off-the-list frequencies with straight PBP ... try 16 Mhz !!! it will be so much simpler ...

May be some ones here could explain you how to modify the PbPlib files ... to run a True 15 Mhz Xtal !!!

I'd really love to read them too ... humour.
