Hello everyone,

I am trying to program a 16F84 and I am having some difficulties.

What I want to do is change the state of outputs portA and port B at the same time but I get errors when I assemble.

Can someone take a look and please help me out?

Thank you so much.

Sincerely,
Joey Hernandez.

Here is the program:

movlw b'10111101'
movwf PORTB
call Delay500

goto MainLoop ; do this loop forever
end


; --------------------------------
; SUBROUTINE: waste time for 500mS

;
Delay500 clrf DelayA ; clear DelayA to 0
clrf DelayB ; clear DelayB to 0
movlw 3h ; set DelayC to 3
movwf DelayC
Wait1 decfsz DelayA ; subtract 1 from DelayA
goto Wait1 ; if not 0, goto Wait1
decfsz DelayB ; subtract 1 from DelayB
goto Wait1 ; if not 0, goto Wait1
decfsz DelayC ; subtract 1 from DelayC
goto Wait1 ; if not 0, goto Wait1
return ; finished the delay

end

Correction on the spacing of the program.

Even though the program looks wrong because of the spacings, the spacings where correct the got repositioned when I copied and pasted it to the Electro Tech message body.

Be careful where you place the END statement. All statements are ignored after that.
