help me in my program

portbbits.rb0

hi
i write this program to read from sensor and display output on lid but when i programed my pic and but it in the circuit it is either always on or it is off so what should i do here is my program
#include <p18f4520.h>
#include <stdio.h>
#include <delays.h>
#pragma config WDT = OFF
void delay_ms(long t);
//unsigned int count;
int count1;
void main (void)
{
TRISD=0;
TRISC=1; is input and output from sensor is connected to it
TRISA=0;
//PORTC=0;
//LATA=0;
while(1)
{
//PORTBbits.RB0= 0; //portb0 is input
PORTDbits.RD0=0; portd is output and intput to sensor
//LATC=1; //porta0 is output
Delay1KTCYx(1); //wait for 1ms
//PORTBbits.RB0 =1;
PORTDbits.RD0=1;
Delay1KTCYx(1); //wait for 1ms
PORTDbits.RD0=0;
//PORTBbits.RB0 =0;
while(LATC==1)
{
//if(LATA==0)
// printf("error\n");

//else
//{
count1++;
// PORTC=count1;
PORTA=0xFF;
//printf("correct\n");
//}

while(LATC==1)
{
if(LATC==1)
{
count1++;
// PORTC=count1;
PORTA=0xFF;
//printf("correct again\n");

}
}
}
if(LATC==0)
{
//PORTC=0;
PORTA=0x00;
//printf("end\n");
}
}
}

p18f4520.h sensor program

i didn't got you? what thing is "always on or off"

 

[qatar.engineer]

p18f4520.h program

the leds is always on or off

p18f4520.h

There are too many Ambiguities in your program
First of mention which compiler are u using

and how are u getting data of interrupts from sensor

 

[qatar.engineer]

trisa vs lata

i am using the c18 comiler for mplab with picstrat and i do not get you when you said

how are u getting data of interrupts from sensor

 

[saeed_pk]

porta and lata in the pic

Can u send me C18 Compiler from microchip

i need that compiler can u

 

[tanzil_dhk]

latc c18

C18 is a free compiler provided by microchip . download from their website.

}

Have you put the pull up resistor?

pic latc

which sensor are you using actually.
