Overall Structure A program is made up of the following four elements in a file Comment Pre Processor Directive Data Definition and Function Definition Every C program must contain a main function which is the starting point of the program execution The program can be split into multiple functions according to their purpose and the functions could be called from main or the sub functions In a large project functions can also be placed in different C files or header files that can be included in the main C file to group the related functions by their category CCS C also requires to include the appropriate device file using include directive to include the device specific functionality There are also some preprocessor directives like fuses to specify the fuses for the chip and use delay to specify the clock speed The functions contain the data declarations definitions statements and expressions The compiler also provides a large number of standard C libraries as well as other device drivers that can be included and used in the programs CCS also provides a large number of built in functions to access the various peripherals included in the PIC microcontroller 4 2 Statements STATEMENT EXAMPLE if expr stmt else if x 25 stmt else 1 while expr stmt while get_rtcc 0 putc n do stmt while expr for exprl expr2 expr3 stmt do putc c getc while c 0 for 1
