| PICkit2+18F4580 |

Hello!
I'm sorry, I can't speak English, only little bit! :(
I have a problem with a CCS+MPLAB+Pickit2.
I write a program, in CCS, but not good :(
bit of the program:
| Code: |
for(i=4;i>0;i--)
{
fok=read_eeprom(i); //EEPROM KIOLVASÁSA, első induláskor 20fokra állítása
if((fok>10) || (fok<35) )
{
write_eeprom(i,20);
}
}
|
If i go debugger mode in MPLAB, the program all steps i=6. But, I replace i variable other (ex: k), then the decrement is fine, but the IF command always true. (Even if fok=20, and even if fok=255 )
And in running the program include a few similar bug.
I use, MPLAB 8.43
PICkit2 last firmware
and I tried two 18F4580.
Pleas help me!
Thx!  |

Hi,
Your if statement reads (in English), if fok is greater than 10 OR fok is less than 35 then....
So, if fok = 20 then fok is less than 35 and if fok = 255 then fok is greater than 10 !
I think what you want to write is : if ( ( fok > 10 ) && ( fok < 35 ) )....
