| debug/release versions |

Hi all.
Can anybody point me to way of doing printf in debug version with a macro?
The same macro in "release" version would do nothing?
It's possible do do this with CCS C?
Thank you. |

Did you try with #ifdef preprocessor directives?
I can´t fully understand what do you need, please could you write an example of
what do you want to show/hide while in "debugg mode or in "release mode"?

A macro.
| Code: | | trace("Something %d, else %Ld", x, y); |
that in release just won't do anything... |

Try this. It uses a debug macro from the CCS file Ex_Macro.c.
| Code: | #include <16F877.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)
//#define DEBUG 1
#ifdef DEBUG
#define debug_printf(x) printf("%s variable value is %d\r\n",#x,x);
#else
#define debug_printf(x)
#endif
//==================================
void main()
{
char c;
c = 0x55;
debug_printf(c);
while(1);

I wish to be more generic like: | Code: |
trace("This is debug value no. %u with address %u", value, address);
trace("Just a line");
trace("Three numbers: %u, %u, %u", number1, number2, number3); |
I believe this can be done with va_arg, etc.
I've never worked with this, and I don't know the usage.... |
