Hey guys and gals,

Having an issue with the following code,

Error   : A12202: Not a hc12 instruction or directive

main.asm line 18   

Error   : A12202: Not a hc12 instruction or directive

main.asm line 20   

Error   : Compile failed

That is the error Im receiving, it is saying that 'DB 0' is not an HC12 instruction.
Although when I compile this exact code in the lab at my college it compiles just fine.

Has anyone used CodeWarrior before and know what might be causing this issue?
I have mc9s12dp512.inc included in the project. Its an absolute assembly program, so no C,
and is not relocatable, so there is no prm file to edit.

Any idea? this is driving me nuts as I'm working on a micro mouse and would much rather work
home than sit in the college's labs.

Why are you trying to stick nulls in a code segment? It's treating the db directive as if it were an instruction, which it isn't. That'll only work in a data section.

[spcm0012]

Was attempting to Null terminate the msg's? If I remove both the db lines, I end up with a bunch of garbage on the lcd after the messages.

Also the lines:

 LDAB #$C0              

        JSR  [lcd_cmd-*-4,PC]

are supposed to works as a line jump, so msg1 prints on one line and msg2 prints on the second, but with out the 'db 0' it prints msg1 and msg2 on the first line, garbage, then msg2 on the second line followed by garbage.
Obviously, Im going about clearing the lcd in the wrong fashion, how should I go about removing the garbage?

What exactly does FCC do?

[spcm0012]

fcc (form constant character)
This directive allows us to define a string of characters (a message). The first character in
the string is used as the delimiter. The last character must be the same as the first character
because it will be used as the delimiter. The delimiter must not appear in the string. The
space character cannot be used as the delimiter. Each character is encoded by its corresponding ASCII code.
For example, the statement:
alpha fcc “def”
will generate the following values in memory:
$64
$65
$66
and the assembler will use the label alpha to refer to the address of the first letter, which is
stored as the byte $64. A character string to be output to the LCD display is often defined using
this directive.

Wait...is FCC a directive or an assembly instruction?

[spcm0012]

its a directive. Sorry if I'm a little confusing, Im a tad confused as its my first time working with the HCS12 and havent done any assembly work in about a year.

[dargueta]

No worries. :)

This is strange, though...you should be able to do something like this. Try doing something like FCC "",$0,""

[spcm0012]

As in:

FCC "Line 1", $0, ""
FCC "LIne2", $0, ""

where the second set of quotations on each line is the delimiter?

OR:

FCC "Line 1", $0, "Line 2"

where the $0 is the delimiter?
If the second way, would that not impede the ability to print out each msg block on separate lines of the LCD?


EDIT:
FCC "Line 1", $0, ""
FCC "LIne2", $0, ""

Will not work, expects an end of line statement.

So, I replaced DB with FCB and that seems to work fine, in my mind DB and FCB have the same function, as well as DC.B, Oh well.

Well there you go. Might want to read the documentation a bit more next time. :D
