Dear All,

I need add continuously use program subroutine as header file to my project folder

Example In Assembly

delay subroutine is using continuously, therefore I need use delay subroutine in separate file and add to main program like we add processor register file (#include <p16f877a.inc>)
Hopefully anybody understand what I need is

My MCU is 16f877a

Language is Assembly

Please advice


Thanks in advance

Hi,

Back with assembler ?

Example attached.. for 18Fs but think on the 16F you might have to place the #includes at the beginning of your main code with after the list.

dear wp100,
Thanks for the reply
I did it like this and "delay.inc" file include to the project folder
Code: 
status		equ		0x03
trisc		equ		0x87
portc		equ		0x07

#include	<p16f877a.inc>
__config 3f39
[COLOR="#FF0000"]#include delay.inc[/COLOR]


start		goto	main
main		call	sys_init
			call	led_on
			
led_on			
loop		movlw	0xff
			movwf	portc
			[COLOR="#FFA07A"]call	delay[/COLOR]
			clrf	portc
			goto	loop

sys_init	bsf		status,5
			clrf	trisc
			bcf		status,5
			return

then following error is occurring, please help

I never forget Assembly
 

Hi,

This should work for you - but check the osc in the config bits XT = 4meg and below
Code: 
;status		equ		0x03     no need to specify - the 877a.inc file contains all the system registers
;trisc		equ		0x87
;portc		equ		0x07


			list		p=16f877A	; list directive to define processor
			#include	<p16f877A.inc>	; processor specific variable definitions


		__CONFIG _CP_OFF & _WDT_OFF & _BODEN_OFF & _PWRTE_ON & _XT_OSC & _WRT_OFF & _LVP_OFF & _CPD_OFF

;		__config 3f39   ??  this selects the RC osc, Watchdog Enabled and LVP on - which you do not want
;							use the full version as above so you can always see what bits you have set		


			cblock 0x20			; specify user registers
			d1,d2,d3			; delay work files
			endc



			org 0x0000
			goto	main

			#include delay.inc

main		call	sys_init
			call	led_on
			
led_on			
loop		movlw	0xff
			movwf	portc
			call	delay
			clrf	portc
			call	delay  	  ; also need a delay here otherwise the led will be on all the time
			goto	loop

sys_init	clrf	PORTC	; ensure portC is off.
			banksel	TRISC
			clrf	trisc
			banksel	0
			return


			end

Dear wp100,

Big thanks for the reply and more advice . also I understand that individual bit configuration is better than the use of config hex word. If you do not take anger I would like to more clear out the bit configuration that you pointed out with my suggestion. please see the picture

Please advice
Thanks in advance

Hi,

No, you are right, I read your hex config value incorrectly, sorry.

As you say is always better to list the bits in full, but if its a hex number then after building it, use MPlabs, Configure, Configuartion Bits to check the values.
