CHAPTER 12

Arduino Libraries

In Chapter 11, Table 11-1 presented a number of standard C header files that are available for use in your programs. Most of these header files are used in conjunction with their associated Standard C library and the functions they hold. A C library is nothing more than a group of (often related) functions that have been pre-compiled into what is called a library file. Conceptually, you can think of a library file as being organized like a book. At the front of the file is an index of each function in the library, followed by an offset that tells where the code for that function can be found. One of the beautiful ...
