Need help with PIC Macros

Started by stephendbarnes April 16, 2003
Hello all,
I have been attempting to make use of Karl Lunt's PIC Macros with no
success
during the build phase. I have followed his instructions and emailed
him for
help with no response. I'm using MPLab 6.20 and writing some test
code for
the 16F84A. The
following text describes my code and the errors upon build. Could
anyone
take a look and see if you could provide some insight? Thanks in
advance for
any help.

Regards,
Stephen D. Barnes

My code follows:

**********************************************************************

When I build I get the following error:

**********************************************************************

Soooo... I created a linker script conforming to MPASM spec which
reads as
follows and is part of the MPLab project:

Build now reports the following error:

Hello again!

Put 'select' as an instruction before the first 'case' statement and
put 'endselect' as as instruction after the last 'endcase'
statement. Also, change the file name to Macros.inc and change the
include statement to match. You do NOT want to assemble separately
the macro library as it contains only definitions. No code is
emitted until the macro is envoked (or expanded if you will).

Lacking the documentation make the library hard to use. If you see
these kinds of errors, look at the variable that was undefined and
see where the macro library was emitting that code (the line number
in the error message). Then wander around and find out why.
Documentation would be better.

One thing to look at - the comment on the 'movf PORTA,0' is incorrect
because you are moving the entire 8 bit PORTA byte to W. More
serious, using 0 instead of W for the destination makes the
instruction hard to read. Both W and F are defined in the 16F84a
include file - you don't need to define them.

I haven't played with this particular macro library but when I saw it
a while back I thought it was rather well done. Enjoy!

Another 'readability' issue - you might think about using BANKSEL
TRISA instead of BSF STATUS,5. Then you can change to bank 0 for
PORTA by BANKSEL PORTA instead of BCF STATUS,5.

See the help file but the short answer is that you can move quickly
to the bank of ANY variable and you don't have to remember where you
put it. Maybe not much of a problem with the 16F84a but the 16F877
has a 4 banks to contend with. --- In , "stephendbarnes"

Thanks to "rtstofer" for both replies. I' going to try out your
suggestions. Thanks again for all the excellent help!

I'm back! Tried out your suggestions and it compiled with no errors,
BUT, when I attempt to debug using MPLab SIM I get no colored pointer
next to the line numbers and "step into" does not appear to work. Is
this because of the inclusion of the macros? Also, the compiled hex
file is only six bytes. Any clues or should I just abandon the macros
and bite the bullet and learn to hard code this stuff?

Steve

No, don't give up on the concept of macros although the NEXTF macro
is incorrect. Doesn't matter, you're not using it. But it shows
that you can't trust anybody's code - and particularly not mine. When I assemble the code I get a map at the end of the .lst file that
shows 38 words used and an additional 'x' where the status word is
programmed. You show see this as well. The list file is 900 lines
long! Probably should do a NOLIST before the '#include <macros.inc>
and a LIST after it. This will cut the listing down to about 260
lines - but the map is the same. One thing I did (although it
doesn't matter) is to move the .inc file to the same directory as the
other 'includes' "C:\Program Files\MPLAB IDE\MCHIP_Tools". Are you
using MPLAB IDE 6.10.0.0 or later? If so, I would expect your list
file to be on the order of 900 lines with 38 words emitted. On my machine I can definitely step through the code include walking
through the macros as they are expanded. Step by step perfectly. Of
course after the endselect macro the code 'falls' into reverse,
executes a return to nowhere and starts over again a Main. You
should probably put a label ahead of the 'select' and a 'goto
MyNewLabel just after the 'endselect'

Don't know what else to say, it works over here! --- In , "stephendbarnes"

Also, as a programming issue, the select statement will execute
the 'default' statements (those between the last endcase and the
endselect) if the value in W is not one of the tested cases. This
might be ok - you don't have any default statements. But you might
want to force W to have only those bits under consideration:

..MOVF PORTA,W
..ANDLW B'00000011' ; look at bits 0..1 only

..select
....case 0
......call something
....endcase
....
....case 1
......call something_else
....endcase
....
....case 2
......call something
....endcase
....
....case 3
......; ignore this case
....endcase
..endselect

Here every potential value has been handled - no possibility of input
without matching code.

OOPS! Of course the new label in my prior message goes ahead of the
MOVF PORTA,W. Comes from typing without thinking.

I think I see what is happening but I don't know what to do about it.
The compiler is actually not looking at my code at all! When it gets
to the "#include macros.inc" it compiles the macros and skips the
rest of my source! If you would like to see the .lst I'll post it for
you to look at. Thanks again for your help.

Steve

I finally figured out how to attach a zip file - I have to send it by
email to from my registered mail account. I
can't do it from work so I will post it tonight.

I have a zip file with the .asm, .inc and related project files -
known to work. Just extract to c:\test\ and open the project in
MPASM IDE.

I tried to create the failure you are having and can't seem to
duplicate it. Once we are both working from the same files maybe it
will become clear. --- In , "stephendbarnes"
