Controlling devices using countdown counter

[TAPII]

Below is the code i have developed to control few elements n devices using countdown counter!!Using MPLAB i can compile it well!!bt when i try to similate in proteus it isnt working!!Below is the code:

#include <pic.h>
#include <htc.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#ifndef _XTAL_FREQ
#define _XTAL_FREQ 20000000 //Frequecy of the crystal used in Sk40C
#endif

#define POWERLED RA0 //Indicator of Power Supply (Yellow LED)
#define ALARM RA1 //LED illuminates as timer reaches zero after countdown (Blue LED)

#define DISPLAY PORTD //Connection to the two 7-segment displays

It does not appear that you have disable the ADC capabilities on PORTA and ensured they are digital I/O.

Download the 16F87XA data sheet:

PIC16F87XA Data Sheet

Quote from PICX16F87XA Datasheet

PORTA is a 6-bit wide, bidirectional port. The corresponding
data direction register is TRISA. Setting a
TRISA bit (= 1) will make the corresponding PORTA pin
an input (i.e., put the corresponding output driver in a
High-Impedance mode). Clearing a TRISA bit (= 0) will
make the corresponding PORTA pin an output (i.e., put
the contents of the output latch on the selected pin).
Reading the PORTA register reads the status of the
pins, whereas writing to it will write to the port latch. All
write operations are read-modify-write operations.
Therefore, a write to a port implies that the port pins are
read, the value is modified and then written to the port
data latch.
Pin RA4 is multiplexed with the Timer0 module clock
input to become the RA4/T0CKI pin. The RA4/T0CKI
pin is a Schmitt Trigger input and an open-drain output.
All other PORTA pins have TTL input levels and full
CMOS output drivers.
Other PORTA pins are multiplexed with analog inputs
and the analog VREF input for both the A/D converters
and the comparators. The operation of each pin is
selected by clearing/setting the appropriate control bits
in the ADCON1 and/or CMCON registers.

On a Power-on Reset, these pins are configured
as analog inputs and read as ‘0’.
The comparators are in the off (digital)
state

The TRISA register controls the direction of the port
pins even when they are being used as analog inputs.
The user must ensure the bits in the TRISA register are
maintained set when using them as analog inputs.

Assembly Routine to Configure PORTA Pins

BCF STATUS, RP0 ;
BCF STATUS, RP1 ; Bank0
CLRF PORTA ; Initialize PORTA by
; clearing output
; data latches
BSF STATUS, RP0 ; Select Bank 1
MOVLW 0x06 ; Configure all pins
MOVWF ADCON1 ; as digital inputs
MOVLW 0xCF ; Value used to
; initialize data
; direction
MOVWF TRISA ; Set RA<3:0> as inputs
; RA<5:4> as outputs
; TRISA<7:6>are always
; read as '0'.

You can configure the PORTA using C, the above code should give you an example of its configuration.

By the way, PORTE has the same issue, it is configured as ADC inputs upon powerup as well.
