Newbie question, cannot compile in MPLAB

Dunccc · Nov 26, 2008

Hi All

I'm just starting out with PIC programming and am working through a book called 'PIC In Practice' by D.W. Smith.

At the moment I am simply trying to get some code compiled to test out the very basics, however it would not compile. So I tried to compile just the header file, with the same results. I have not even got as far as attempting to blow the code into the PIC programmer so I believe this is simply an issue to do with the code or the IDE. The code I am trying to compile is as follows:

; HEADER84.ASM for 16F84. This sets PORTA as an INPUT
; and PORTB as an output
; The OPTION Register is set to /256 to give timing pulses of 1/32s
; 1 second and 0.5 second delays are included in the subroutine section.

hi,

To block the warning messages place
errorlevel -302, -207, 205

just above LIST in your program.

this will block these:
Message[302]
Warning[205]
Warning[207]

The ASM 22 is the line number in your code. eg: line #22

Place the CONFIG near the LIST

Compile and repost.

BTW: when you paste your code to the forum, select it and click the '#' symbol to keep the formatting.

;

Code:

 HEADER84.ASM for 16F84. This sets PORTA as an INPUT  
; and PORTB as an output  
; The OPTION Register is set to /256 to give timing pulses of 1/32s

hi,
Copy and paste this code into your MPLAB window, that is replace yours with this.

You were using ZEROBIT twice.!
Also LOOPB,,, Status there is no bit number.
fix the '4FF0' opcode to '3FF0',

EDIT:
#include <p16f84.inc>
if you add this include you dont need to define the Ports
TMR0 equ 1
STATUS equ 3
PORTA equ 5

hi Dunc,
Redited you code, copy and paste this, it does now compile in MPLAB
I have added 'Z' to the Status tests, change it to suit your code.

Let me know how it goes.

Code:

; and PORTB as an output  
; The OPTION Register is set to /256 to give timing pulses of 1/32s

but error missing argument at MAIN_PROGRAM ORG after changed to

MAIN_PROGRAM    ORG

That is the simplest way to fix it. You will also need to remove any linker script that you have. You only need the first two orgs, the one on main is not required.

That is because you replaced it with CODE or you didn't delete the linker script.

If it still doesn't work post your code again.
