| PIC16F84 help!!!! |

 Hi everybody, I need some help with this project, and I think this is the right place to come to. This is the first time I use the CCS, and this is my first program in it. I tested it in Real PIC Simulator, but it seems not to be working.  Here is the code:
| Code: |
#include <16f84.h>
#include <stdio.h>
#define Ld1 ra0
#define Ld2 ra1
#define Start_btn ra2
#define Add_btn ra3
#define Relay ra4
#define Beep rb0
#use delay( clock=4000000 )
#fuses XT,NOWDT,NOPROTECT,NOPUT
byte const Display[10] ={0xDE,0x06,0xB6,0xAE,0x66,0xED,0xFC,0x86,0xFE,0xEE};
void main(void)
{
int Vreme=0,b,i,temp,temp0,c1,c2,t;
set_tris_a (0x06);
set_tris_b (0x00);
port_a = 0x0C;
port_b = 0xDE;
Loop: while(!Add_btn){
for(b=0;b<=416;b++){
Beep = true;
delay_us(300);
Beep = false;
delay_us(300);
}
Vreme++;}
temp0 = Vreme;
c2 = temp%10;
temp/=10;
c1 = temp%10;
port_b = Display[c1];
Ld1 = true;
delay_ms(100);
Ld1 = false;
port_b = Display[c2];
Ld2 = true;
delay_ms(100);
Ld2 = false;
while(!Start_btn){
for(b=0;b<=416;b++)
Beep = true;
delay_us(300);
Beep = false;
delay_us(300);}
Relay = true;
for(i=Vreme;i<=0;i--){
temp = i;
c2 = temp%10;
temp/=10;
c1 = temp%10;
for(t=0;t<=300;t++){
port_b = Display[c1];
Ld1 = true;
delay_ms(100);
Ld1 = false;
port_b = Display[c2];
Ld2 = true;
delay_ms(100);
Ld2 = false;
}
}
if (i==0)
Relay = false;
goto Loop;
}

In CCS, an 'int' is an unsigned 8-bit integer. It can only go from 0 to 255.
If you need a larger value, then use 'int16'. In the code above, 'b' and 't'
should be declared as 'int16'
If you need a signed value, then put 'signed' in front of the declaration.
This is all explained in the CCS manual. |

Thanks, it seems to fix the ccs code, but still not working in Real Pic Simulator...  |

#define Ld1 ra0
#define Ld2 ra1
#define Start_btn ra2
#define Add_btn ra3
#define Relay ra4
#define Beep rb0
What are ra0, ra1, ra2, ra3, ra4, rb0 and where are they defined ?
I assume they are suppose to be port pins. |

Yes, they are defined in pic16f84.h, but i'm not sure does it work like this #byte port_a=0x05
#bit ra4 =0x05.4
?????  |

| whose header R U using ????? |

my 16f84.h file has no def for ra0 etc
and your code won't compile.
where did you get your header with this set of nonsense defs?
i think you mean PIN_A0 PIN_A1 etc
i'd try for a start looking in the CCS header files
and using THOSE defs
just a comment - simulators are just swell if you never plan to make a working device/system - but the real test is BUILDING it and trying with actual hardware.
but before any of that it has to at least compile.
your code does NOT - at least under CCS |

I'm not sure is it header from ccs, when I opened it I found ra0, ra1 etc.
I'll try it with some other header, that have PIN_A0...thx  |
