Multiple Compilation Units
Traditionally, the CCS C compiler used only one compilation unit and multiple files were
implemented with #include files. 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).
The following is an overview of a multiple compilation unit example. For the example used here,
see the MCU.zip in the examples directory.
