i'm new in microcontroller, and i'm using PIC16F84A. Can somebody please tell me what's wrong with my program, i just wish to set portA and portB as output and illuminate LED which will be connected to the ports.

#INCLUDE P16F84A.INC

__config _XT_OSC & _CP_OFF & _PWRTE_OFF & _WDT_OFF

MOVLW 0x00
BSF STATUS, RP0
MOVWF TRISA
MOVWF TRISB
BCF STATUS, RP0
MOVLW 0xFF
MOVWF PORTA
MOVWF PORTB

end
here's the error:

Hi,
Your code reformatted.

You need to add more information in the header.

Code: 
	list      p=16f84A         ; list directive to define processor
	#include <p16F84A.inc>        ; processor specific variable definitions
	errorlevel  -302 , -207             ; suppress message 302 from list file

	__config _XT_OSC & _CP_OFF & _PWRTE_OFF & _WDT_OFF


	ORG     0x00            ; processor reset vector
	goto    main              ; go to beginning of program
	

	ORG     0x004             ; interrupt vector location
	nop
	retfie                    ; return from interrupt

 
main:
	movlw	0x00
	bsf	STATUS, RP0
	movwf	TRISA
	movwf	TRISB
	bcf	STATUS, RP0
	movlw	0xFF
	movwf	PORTA
	movwf	PORTB

	end

hi,
Did you copy the edited version of the program I posted, showing the Headers.???
 
s0 sorry... thank u s0 much!!:D

it really works!!your d best man!!:) thank you s0 much!!!!by the way, do i really need to type those headers everytime i try to create a program?

Yes, i already copied and pasted it on MPLAB, still, it didn't work... :(

hi,
Modified your program to flash the PORTA and B , on/off once per second.

It does work in Oshonsoft Sim OK.?


Code: 
	list      p=16f84A         ; list directive to define processor
	#include <p16F84A.inc>        ; processor specific variable definitions
	errorlevel  -302 , -207             ; suppress message 302 from list file

	__config _XT_OSC & _CP_OFF & _PWRTE_OFF & _WDT_OFF

	
d1  	equ 0x20
d2 	equ 0x21
d3	equ 0x22


	ORG     0x00            ; processor reset vector
	goto    main              ; go to beginning of program
	

	ORG     0x004             ; interrupt vector location
	nop
	retfie                    ; return from interrupt

 
main:
	movlw	0x00
	bsf	STATUS, RP0
	movwf	TRISA
	movwf	TRISB
	bcf	STATUS, RP0

loop1:
	movlw	0xFF
	movwf	PORTA
	movwf	PORTB
	
	call Delay
	
	movlw	0x00
	movwf	PORTA
	movwf	PORTB

	call Delay

	goto loop1

Delay:
			;999997 cycles
	movlw	0x08
	movwf	d1
	movlw	0x2F
	movwf	d2
	movlw	0x03
	movwf	d3
Delay_0
	decfsz	d1, f
	goto	$+2
	decfsz	d2, f
	goto	$+2
	decfsz	d3, f
	goto	Delay_0
			;3 cycles
	goto	$+1
	return

	end

The header detail is VITAL in order for MPLAB to assemble your programs.

Make the Header part a text file, which you copy and paste.
NOTE: different PIC types require different Headers.

EDIT:
if you connect LED's to the PIC pins, use a low value resistor in series with the LED, say 330 ohms
