Tutorial Request: PBP programming + PIC16F877A + VB6 and Proteus simulation.

[aljabar]

I need some basic tutorial both of VB6 and PIC16F877A to control vice verse LED and Switch using PBP or ASM (PIC16F877A) in Proteus simulation.


I believe, many member will interest and appreciated for the contribution

Hi,

For beginners Assembly look at these tutorials.

A simple led flasher program is below, just run it though MPLAB to produce the hex file for Proteus.

;       progam to flash all of PortB pins on and off every 4 seconds, using a 4mhz crystal
;		(2 second flash with  8mhz crystal)


		list p=16f877a
		include p16f877a.inc
		__CONFIG _CP_OFF & _WDT_OFF & _XT_OSC & _PWRTE_ON & _LVP_OFF
	
		cblock 0X20			; specify user regiaters
		d1
		d2
		d3
		COUNT
		endc



		org 	0x000
		GOTO	Main



Main	CLRF	PORTB		; Set portb,c,d to digital outputs
		CLRF   	PORTC
		CLRF 	PORTD
		BANKSEL TRISA
		CLRF	TRISB
		CLRF 	TRISC
		CLRF 	TRISD
		BANKSEL 0

		

LOOP						; main program looP
		CALL	DELAY4s		; call this subrutine
		MOVLW   0xFF
		MOVWF	PORTB		; Set  port HIGH

		CALL	DELAY4s

		MOVLW   0x00
		MOVWF	PORTB		; Set  port LOW
		GOTO	LOOP		


;  SUBROUTINES
	
DELAY4s						; 4 SECOND DELAY
		movlw	0x23
		movwf	d1
		movlw	0xB9
		movwf	d2
		movlw	0x09
		movwf	d3
Delay_0
		decfsz	d1, f
		goto	dly1
		decfsz	d2, f
dly1	goto	dly2
		decfsz	d3, f
dly2	goto	Delay_0
	

		return
