I'm always curious to know what kind of person it is who won't bother to do simple research, then won't bother to take the time or the effort to at least write a complete sentence (much less have the courtesy and pride to use correct grammar and punctuation), yet they expect others to take the time to try to figure out what it is they're asking, then to take the time to proffer an answer.
For some reason, this forum seems especially afflicted.
I used PIC and didn't use a library. Challenge yourself to do the same. Otherwise, if you are less ambitious, go here and click on the DOCUMENTS tab...
