Hi, I tried it with another PIC with the define statement on top of the code. It worked fine. I can't use external resonator, as I am using those pins.
How do I know which PICs need this DEFINE statement and which don't?
I am trying to serout with 12F635 & serin at 16F676. It is still giving problems, does 635 also needs some kind of calibration? Thanks

The same way you know about all the other things the chip does ... the Datasheet. (Oscillator section)Originally Posted by financecatalyst
Only the really OLD chips need OSCCAL calibration.
No, the 635 doesn't need an OSCCAL.I am trying to serout with 12F635 & serin at 16F676. It is still giving problems, does 635 also needs some kind of calibration? Thanks
It has a precision multi-speed internal oscillator, and you can select the speed with OSCCON. But it defaults to 4Mhz.
It's factory calibrated, and the calibration can not be erased.
The 635 has a comparator that needs to be turned off though.
CMCON0 = 7
