external interrupt at pic16f18176

[sezgin ozan]

Hi everybody , I need external interrupt on PIN_A3 at "pc16f18176", does any know how to set, I tried as below at main() but does not work


#INT_EXT
void IR_INT(void) {
UPD6121_InterruptService();

}



enable_interrupts( INT_RA3_H2L );
enable_interrupts(INT_TIMER0);
enable_interrupts(GLOBAL);

Very simple reason. Wrong interrupt.....

INT_EXT, handles the EXT interrupt pin.

The interrupt on change for port A, is INT_RA

Also beware that you have to clear the latch for the change interrupt for the
pin you are using (clear_interrupt), in the handler.
There is a single interrupt (which the compiler handles for you), and then
separate latches for each pin.
