Hello guys,
Problem with the very basics. I am stuck with the external interrupt INT0 at RB0. Controller - PIC 18F47J53 MPLAB IDE, Microchip C Compiler
I could not figure out what is wrong with the following code. Kindly help me out to make this work!!
#include #include #include
#pragma config OSC = HS #pragma config WDTEN = OFF #pragma config XINST = OFF void InterruptServiceHigh(void); void InterruptServiceLow(void);
int x;
void main(void) {
INTCONbits.INT0IF = 0; INTCONbits.INT0IE = 1; INTCON2bits.INTEDG0 = 1;
INTCON2bits.RBPU = 0; //EnablePullups(); TRISE = 0; TRISBbits.TRISB0 = 1; RCONbits.IPEN = 1; INTCONbits.GIE = 1; INTCONbits.PEIE = 1;
while(1) { PORTE = 0x01; }
}
// High priority interrupt vector #pragma code InterruptVectorHigh = 0x08 void InterruptVectorHigh(void) { _asm goto InterruptServiceHigh _endasm }
// Low priority interrupt vector #pragma code InterruptVectorLow = 0x18 void InterruptVectorLow(void) { _asm goto InterruptServiceLow _endasm }
// Interrupt Service Routine // Interrupt pragma for high priority #pragma code #pragma interrupt InterruptServiceHigh void InterruptServiceHigh() { // function statements
if(INTCONbits.INT0IF) { x = 0; while(x
