is it a correct program? and what is utils.h?
You do not need to learn the Cx51 User's Guide in the sense of memorising it by heart; it is a reference document - so you should refer to it when required.
But you do need to spend time gaining familiarity with it - so that you can find your way around easily.
You also need a good understanding of the 'C' Programming language.
One interesting thing with this incomplete program.
Not only are the two header files needed.
But one step later, the linker will also need access to the object code for the actual implementation of whatever functions that the lcd and utils header files happens to mention.
