almost nothing...  When I switch from F84 to F628, most of the time, I only
need to change the memory location of my variables (in F84, I starts from
0x0C, and in F628, it needs to start from 0x20)...  It's also nice that the
PORTA, PORTB pin locations and functionality pretty much stay the same.  One
thing though, PORTA comparator is active by default.  So, you will have to
turn it off if you want to use it for digital I/O pins...  but if the code
in F84 has only been using PORTB, I don't think there is anything to change
except for changing the memory location...

Subject: [PIC]: Which PIC?


hi All

I see that most of the list people recommend the 16F628 (as a startup pic
for newbies or as a replacement for other rare pics) my question is (for a
guy that didn't write its own programs yet)
can someone explain in simple language, what are the differences between
them?
can I implement a program, lets say, a program that someone wrote to 16F84?
what changes I need to do ? or just program it and it will fit?
and where I can find tutorials for newbies on the 'net? and I mean for real
NEWBIES! :-)

Happy new year to ALL! and may god bless you with happy programming and
bugless YEAR!

Tal
