I'm trying to code an IR shooting gallery project where the 18f4685 microcontroller controls when the start button is pressed (and difficulty setting is chosen) to start a 30 second countdown, lighting LEDs when a target is hit, and sending each hit to the scoreboard. When the time is up, I want the program to stop registering scores and hits. Can anyone help see what I'm doing wrong?
C:
#pragma config MCLRE=OFF, WDT=OFF, LVP=OFF, OSC=IRCIO67, PBADEN=OFF
#include <xc.h>
#include <stdio.h>
#define _XTAL_FREQ 8000000 /* Set oscillator frequency to 8MHz */
#define switch1 PORTAbits.RA0 // Switch on RA0
#define switch2 PORTAbits.RA1 // Switch on RA1
#define switch3 PORTAbits.RA2 // Switch on RA2
#define led1 LATBbits.LATB0 // led1
#define led2 LATBbits.LATB1 // led2
#define led3 LATBbits.LATB2 // led3
#define score PORTBbits.RB3 // Scoreboard
#define timer PORTBbits.RB4 // 7-segment timer
#define diff1 PORTDbits.RD7 // Difficulty switch
#define start PORTDbits.RD5 // Start button
int x=30; /* Sets variable x=30 at the start of the function. This starts
the count at 30 seconds for the countdown. */
void main(void)
