Has any one had problems with quirky programming with the P16F627/8. I'm trying to migrate from the good old p16f84. These two device share some simular operations and some pin to pin compatible. But when I tried the same function in the 84 onto the 627( the 627 has this function), the 627 had irratic and wired operation, and sometimes no function at all. I have disable the LVP and comparator in the 627. May be I missed something? Any body help please ?
May be I should have said I was using C compiler. So the memory location or register bank etc has been taken care of by the compiler. I think may be it's the configuration word. How do I know what is the correct word to set?
I'm bit surprised that there's not much been said about the Configuration word, and yet it's so important. I remember I had some troubles when I first started programming the PIC. Sometimes I wasted hours looking for programming error and it turned out just a mistake on the configuration word. I wonder if many people had this problem.
