I get error using 12f629 and RB0/INT

[artloya]

I have been trying make a simple application to learn interrupt routine using a 12F629 chip. I get:

=======================
Using TMR interrupt work fine, but I can't get RB0/INT
I checked the asm code and did see INTCON, 1 for the timer.
but I'm stumped with RB0/INT (GP2/INT)
I hope you can help!

Thanks,
Art

Can you please post the contents of your "12c629MacroTMRx.c" here - especially the lines around line 143.

If you load the c file in notepad (or click "chip..view c file" from within Flowcode), you can use the "edit..goto" menu item to go to the line with the error (if this notepad menu item is disabled, you may need to turn "word wrap" off).

I created this using the flowcharts, I didn't use C.

this is line 143: void FCM_INTERRUPT_PORTB()

//Macro implementations

void FCM_INTERRUPT_TMR0()

//Calculation
//Calculation:
// COUNT = COUNT + 1
FCV_COUNT = FCV_COUNT + 1 ;


}

void FCM_INTERRUPT_RB0INT()

FCV_COUNT = FCV_COUNT + 1 ;

void FCM_INTERRUPT_PORTB()

void FCM_OutLED()

//turns on led1

// 2 COUNTin mac
//Calculation:
// COUNT2 = COUNT2 + 1
FCV_COUNT2 = FCV_COUNT2 + 1 ;


//Decision
//Decision: A2 = 1?
if( FCV_A2 == 1 )
{
//Output
//Output: 0 -> A0
trisio = trisio & 0xfe;
if (0)
gpio = (gpio & 0xfe) | 0x01;
else
gpio = gpio & 0xfe;


} else {
//Output
//Output: 1 -> A0
trisio = trisio & 0xfe;
if (1)
gpio = (gpio & 0xfe) | 0x01;
else
gpio = gpio & 0xfe;


}


}

also got this today trying a variation of my original program:

Please send the FCF and C files to us and we'll have a look.

Hello Art

I have found the problem in your code.

The error is occurring on the following line of code.

0x0000000B.4=1;

Now this is because the compiler is trying to write a value of 1 into bit 4 of register 0. The compiler is trying to do this because you entered 0x0000000B into the interrupt register. Obviously this is not correct.

I see that you are trying to get an interrupt to occur when GP2 is pressed.

Now we have taken the work out of this for you so you can use the predefined RB0 interrupt to do the GP2 interrupt.

So if you open up the interrupt enable and change the custom to RB0 then your program should compile and run correctly.

If you wanted to create custom interrupts then you would have to use the register name in lowercase eg intcon and the register bit in upper case eg INTE

Hope that this helps.

I tried this again, still no luck
