CCS C Compiler Manual PCB / PCM / PCH

Multiple Compilation Units
Multiple compilation units are only supported in the IDE compilers PCW, PCWH,
PCWHD and PCDIDE. When using multiple compilation units, care must be given
that pre-processor commands that control the compilation are compatible across all
units. It is recommended that directives such as #FUSES, #USE and the device
header file all put in an include file included by all units. When a unit is compiled it
will output a relocatable object file (*.o) and symbol file (*.osym).
There are several ways to accomplish this with the CCS C Compiler. All of these
methods and example projects are included in the MCU.zip in the examples
directory of the compiler.
Full Example Program
Here is a sample program with explanation using CCS C to read adc samples over rs232:
///////////////////////////////////////////////////////
/// This program displays the min and max of 30, ///
/// comments that explains what the program does, ///
/// and A/D samples over the RS-232 interface. ///

#fuses NOPROTECT
#use delay(crystal=20mhz)
// preprocessor directive that selects
// the chip PIC16F887
// Code protection turned off
// preprocessor directive that
// specifies the clock type and speed
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7) // preprocessor directive that
includes
// the rs232 libraries
