Is there any way to read PROCESSOR_TEXT in the project file
PostPosted: Wed Mar 05, 2014 1:34 pm     Reply with quote

I am using CCS 5.20 compiler
Is there any way to read PROCESSOR_TEXT from the project file, or get the processor identification that the compiler is set to.

I have a program that can run on different PICS, but it would be nice if I could use preprocessor commands to select the right pieces of code based on the processor. I understand once #device is set I can determine that, but setting #device based on the compiler setup would be great.

The CCS function getenv() will get the PIC if you give it a parameter
of "DEVICE". You can then use #if and #elif statements to setup the
correct source code for a particular PIC. An example of this is given in:

See the examples eg EX_8pin.c

Here are the extract of the top of the file.

Code:

#if defined(__PCB__)
#include <12C508.h>
#fuses INTRC,NOWDT,NOPROTECT, NOMCLR
#use delay(clock=4000000)
#define GP0 PIN_B0
#define GP1 PIN_B1
#define GP2 PIN_B2
#define GP3 PIN_B3
#define GP4 PIN_B4
#define GP5 PIN_B5

#elif defined(__PCM__)
#include <12C671.h>
#fuses INTRC,NOWDT,NOPROTECT, NOMCLR,NOLVP
#use delay(clock=4000000)
#define GP0 PIN_A0
#define GP1 PIN_A1
#define GP2 PIN_A2
#define GP3 PIN_A3
#define GP4 PIN_A4
#define GP5 PIN_A5

#endif


Don't know if this helps but that's my understanding of what you are asking.

I was somehow under the impression that getenv returned the #device setting. Guess I was wrong, it does exactly what I want.

Thanks.
