def Files for CCS compiler?
PostPosted: Tue May 15, 2012 2:22 pm     Reply with quote
Hi

I know that most of the functionalities in PIC's are accessible via use of CCS built in library functions.

However, sometimes it is necessary to manipulate a specific Special Function Register myself manually.

As a solution, I include a "Special Function Register definition header file" that contains definitions such as below
Code:

#DEFINE POSTINC0 0XFEE
#DEFINE POSTDEC0 0XFED
#DEFINE PREINC0 0XFEC
#DEFINE PLUSW0 0XFEB
#DEFINE FSR0H 0XFEA
#DEFINE FSR0L 0XFE9
#DEFINE WREG 0XFE8
#DEFINE INDF1 0XFE7
#DEFINE POSTINC1 0XFE6
#DEFINE POSTDEC1 0XFE5


So that I can write directly to register such as ADCON1.

However, creating such file is too tedious and time consuming so I am wondering if the compiler provides some method as to I can access special functions by name without definining it's mapping.

Thank you
PCM programmer

The CCS IDE (PCWH, PCWHD) has the ability to make it for you.
See the screenshots in this section:

You need the IDE version of the compiler to do this.

Apart from mentioning the option to generate a SFR definition file automatically, it should be said,
that the syntax understood by the CCS C compiler uses #byte and #word statements. Just review the compiler help.
