Hi, everybody
I am working with MSP430FG461H Board.I have a code that author John Davies used in his book.I want to use this code in my different projects like
#include <LCDutils.h> or in a different way.
what should i do.i don't know creating library.I am beginner please help me explicitly and step by step.
This is the code:

If you have the source code, there's no need to deal with libraries. Just include/copy the source .c files into your project and include the associated .h files in your own code files where you want to use the new functions.
Or directly include the code into your .c file (if it isn't so much that it will blur your sight on your own code)
Libraries are usually precompiled, compiler-specific binaries which you add to the projects linker options.
creating library....
project- > new pjt -> lib pjt templet-> lib pjt->
type u r code without void main (void)
compile it.....
linking library with ur project
Now make ur new project -->right click on project name in work space ->add -> add files -> select .lib or .r51 file (from location where u have created library file -> exe->.......)
& also attach .h file location in option -> c\c++ complier ->preprocessor......
Hope it will work...
