Exception must point to constant

[crni2004]

HI !

Im totaly new to pic programming. I wrote small program im CCS C and when i went on compile i get error : Expression must evulate to constant.
OK. I went into help and there was some example but not the solution.

The compiler is pointing to pic.h file and i can't find pic12xxx.h files in my
ccs dir. I dont now how to solve this......

If someone has some solution please write down.

Thanx in advance

You are posting in the wrong forum!
It might be helpful to actually post the code that is giving you a problem.

Ok. Sorry for the forum... Where can i send such questions ?

2.) This is the test code from the microchip debounce.c that i want to test on pic12f675. The orginal hex file packed in example is working fine and i can burn him on chip but now i want to compile this example thru CCS C.

//****************************************************

#include "Debounce.h"
void main(void)
{
Init();
while(1)
{

if (!BUTTON) // sense BUTTON closure
{
ToggleLED();
Debounce();
}
}
}

//***********************************************************
void Init(void)
{
ANSEL = 0b00000000; // configure A/D inputs as digital I/O
TRISIO = D0_1Tris; // GPIO 3,4 outputs, GPIO 0,1,2,5,6,7 inputs
OPTION = 0b11010000; // Timer0 internal clock, 1:2 prescale
GPIO = D0On;
CMCON = 0b00000000; // configure comparator inputs as digital I/O
}

void ToggleLED(void)
{
if(LEDOn)
{
GPIO = D0Off;
}
else
{
GPIO = D0On;
}
}

//----------------------------------------------------
void Debonce(void)
{
unsigned char COUNT = TenMS;

TMR0 = 0;
for(;;)
{
if(!BUTTON)
{
// reset 10 millisecond COUNT if BUTTON pushed
COUNT = TenMS;
}
else
{
// decrement timer COUNT for every Timer0 overflow
if(T0IF)
{
// reset flag
T0IF = 0;

if(--COUNT == 0) break;
}
}
}
}

"and i can burn him" ??!! Programs and chips are women :-)
However, forget the "pic" preamble in file names. Just find "12F675.H" in the "Devices" directory.

My guess is that none of those registers are declared. The device is not specified. No #fuse statement. Debounce is mispelled ;) Take a look at some of the example programs to see how to set up the C file.

Ali,
programs and chips are women because of the phrase you often say when the program/chip not works as well as you intended ;-)

[Guest]

So you burn women
** ;-)) / what a conclusion :-)


OK. I can't start the debounce.c file so i went to another file called EX-8pin.c ( from the CCS example dir ). This file is using 12C508 header file. I'v started compile and all is working fine.
So, ok if i can't use microchip's examples i can use CCS eg.

Now, i'v changed the #include 12C508 to #include 12F675 and a get error "Unknown device type". The 12F675.h file was automaticly opened at line #device PIC12F675....
----------------------------------------------
1.)
I don't get it where is the problem. Basicly now i got the same stuff like in debounce.c file accept this one is i ccs c. I have selected the device from the tools / device selector

2.)
Im using the pickit flash starter kit for 8pins Microchip MCU's and JDM programmer for the rest.
What should i add accept :
"C:\Program Files\Microchip\PICkit\PICkit.exe"%H %D into
"device programmer" part so i can burn this compiled (i hope in future, working program ) to PIC12F675 ?

Stay cool
