"volatile"?
Go look at a good C book, or ask on the comp.lang.c newsgroup.
Folks,
I'm feeling a little sad that the members of this list are not
being more kind to a new user who doesn't understand all the
intricacies of using an embedded processor in C.
If I had known the exact syntax of "extern volatile unsigned..."
I would have replied, but I knew that someone else knew more
about it than I did, so I kept silent.
Now, I'm seeing what I think are kind of snotty replies to this
person asking a question that is completely reasonable.
Could I encourage people to either not post, or post something
helpful.
This business is hard enough to figure out without getting
slapped when you ask a question that is obvious to everyone but
you.
