Code:
unsigned char x;
// Interrupt Handler
void interrupt()
{
// RB Port Change Interrupt
if(PIR1.RBIF == 1) // if the RB Port Change Interrupt flag is set...
{
PORTA.F1 = ~PORTA.F1;//LED on/off on press of switch
x = PORTB; // Need to read or write to the port to clear mismatch condition
PIR1.RBIF =0;
}
}
// code starts here...
void main()
{
TRISA = 0b00000000;
TRISB = 0b00100000; //RB5 defined as input and push switch connected to it
// Set Interrupt Enable bits
INTCON.RBIE = 1; // bit 3 RB Port Change Interrupt Enable
//Set global Interrupt Enable bits
INTCON.GIE = 1; // global interrput enable
while(1) //endless loop
{
}
