| BIT_SET and V 3.249 problems |

Hi,
the BIT_SET function is not working in the compiler version 3.249. it was working fine
with the 3.236 version and when I update it, it stop to work.
do you have any solutions for it?
thanks |

Works for me with int8. Can you be more specific?
| Code: | #include <18F4525.h>
#use delay(clock=12000000)
#fuses HS,NOWDT,NOLVP,PROTECT,PUT,BROWNOUT
#use rs232(baud=19200,xmit=PIN_E0,INVERT,stream=DEBUG,DISABLE_INTS) // STDERR(same as DEBUG)
#case
#zero_ram
//======== MAIN =======//
void main(void)
{
int8 x;
setup_adc_ports(NO_ANALOGS);
set_tris_a(0);set_tris_b(0);set_tris_c(0);set_tris_d(0);set_tris_e(0);
fprintf(DEBUG,"\n\r");
fprintf(DEBUG,"STARTING \n\r");
x=0;
fprintf(DEBUG,"%u\n\r",x);
bit_set(x,0);
fprintf(DEBUG,"%u\n\r",x);
while (TRUE){
}
}

this is the routine.
| Code: |
if (P_PB[c].total_cont >= CNT_db) /* se o contador for maior que a definição de filtro, faça: */
{
P_PB[c].total_cont = CNT_db; /* mantém o valor */
if (P_PB[c].bit_a == FALSE) /* se "P_PB[c].bit_a" for zero, faça: */
BIT_CLEAR(Byte_validoB,c); /* seta bit "c" de "Byte_validoB" */
else /* se não, faça: */
BIT_SET(Byte_validoB,c); /* zera bit "c" de "Byte_validoB" */
}
|
The variable Byte_ValidoB is int.
thanks |

It is still working. Post a complete program. With only a few lines. Like I did.
One of the line should be a bit_set that shows it Not working. |

It´s a part of a huge program (more than 20000 lines)!!
when the condition is TRUE, the correspondent BIT is never set. if I use the 3.236 version everything works fine.
I will try to create a little program with the same routine and see what happens.
thanks |

At least tell us how did you define the bit 'c'

20000 lines. I'm glad I'm not you ; )
This program shows your code chunk. It works as I expect.
Byte_validoB is 1 then 3 then 7, that is bit0 is set then bit 1 then bit2.
I forced your code chunk into the else(bit_set) part.
| Code: | #include <18F4525.h>
#use delay(clock=12000000)
#fuses HS,NOWDT,NOLVP,PROTECT,PUT,BROWNOUT
#use rs232(baud=19200,xmit=PIN_E0,INVERT,stream=DEBUG,DISABLE_INTS) // STDERR(same as DEBUG)
#case
#zero_ram
//======================= MAIN ============================//
void main(void){
struct jnk_def{
int8 total_cont;
int8 bit_a:1; //one bit TRUE or FALSE
int8 bit_b:7; //the rest of the byte waisted
}P_PB[3];
int8 Byte_validoB,c,CNT_db;
setup_adc_ports(NO_ANALOGS);
set_tris_a(0);set_tris_b(0);set_tris_c(0);set_tris_d(0);set_tris_e(0);
fprintf(DEBUG,"\n\r");
fprintf(DEBUG,"STARTING\n\r");
P_PB[0].total_cont=0; //set all to zero
P_PB[1].total_cont=0;
P_PB[2].total_cont=0;
P_PB[0].bit_a=0;
P_PB[1].bit_a=0;
P_PB[2].bit_a=0;
Byte_validoB=0;
c=0;
for(c=0;c<3;c++){
fprintf(DEBUG,"Byte_validoB=%u c=%u->",Byte_validoB,c);
P_PB[c].total_cont=4;CNT_db=3; //4>3 to get into if statement
if (P_PB[c].total_cont >= CNT_db){
//P_PB[c].total_cont = CNT_db;
P_PB[c].bit_a = TRUE; //set to true to get else statment
if (P_PB[c].bit_a == FALSE){
//bit_clear(Byte_validoB,c);
}
else{
bit_set(Byte_validoB,c); //set bit 4 of Byte_validoB
fprintf(DEBUG,".");//to let me know that i did bit_set
}
}
fprintf(DEBUG,"Byte_validoB=%u\n\r",Byte_validoB);
}
while (TRUE){
}
}

I'm giving up. Your not giving me any info to solve your problem. |

Sorry,
I will try to give you as much information as I can. but I don't know why it is not working here.
the 'c' value is an int and it is incremented like c++.
even though, thanks a lot for your help. |

You defined
int8 Byte_validoB
so bit 'c' can´t be bigger than 7
while if you define:
int32 Byte_validoB
bit 'c' can be as big as 31
In CCS an int is 8 bit wide.
