I wound prefer to change your code in the interrupt routine
#byte PORT_B = 0x06
#INT_Timer1
void T1()
{
Output_toggle(PORT_B,0) ;
}

I found out what the problem was, it had nothing to do with the interupt(routine)
I tested 2 variables with an if statement, if (var1 < var2)
If checked the assembly code and i saw ... |

Hello,
You guy's are right.
The bit_test on the PIR1,0 !=1 ensures that the condition is checked and will stop the while loop if the conditiond are met.
This is what i did:
while(( ... |

Hello,
I'm a beginner in programming PIC controllers in C, it's a little different the assembly language.
I made a loop with while statement
[code]
int8 count ;
while (count < 3 &&am ... |

I've installed the MPLAB simulator to see what's happening.
The timer1 interrupt occurs and i made it visible by toggling the LCD backlight.
But when the interrupt service routine is finished, t ... |

I did a test and it don't make a difference
What i did
#byte PIE1 = 0x8C
bit_set(PIE1,0) ;
But i've seen that i don't have a proper interrupt service routine.
The first few lines ,als ... |

Hello,
I'm using an external crystal oscillator to create a real time counter, i've used a 2,457600 MHz crystal.
I've allready checked the oscillation frequency, test was ok
But i ve noticed ... |

Thanks,
I tried the #ROM 2100 command and it really don't affect the ROM counter during compiling. |

Hello,
I'm using a 16f628
I'd like to put a few constants in the eeprom memory, a common solution for this is
#rom 0x2100={1,2,3,4,5,6,7,8}
because my ROM memory is almost full i'd like to ... |
