LASCAR MDM-1 display demo software doesn't compile.

[rngolding]

Hi, has anyone tried compiling the CCS 'analog1' demo software provided for the LASCAR MDM-1 LCD display:-

(available here - http://www.geocities.com/g13685/C_Software.html)

I've tried compiling it, but get the following error:

------------------------------------------
>>> Warning 203 "analog1.c" Line 54(1,1): Condition always TRUE
*** Error 160 "analog1.c" Line 105(0,1): EXTERNal symbol not found mdm_cursor_position
1 Errors, 2 Warnings.
Halting build on first failure as requested.
--------------------------------------------

The author claims it works with the old 3 series PCM compiler but, for the life of me, I can't fathom out out to get it to work with the later 4 series (4.082).

Any help/comments greatfully appreciated

That's a link to the main page. Can you post a direct link to the code
that you downloaded ? Because if I click on the Lascar link, it goes
to a page with a million more links on it.

Hi PCM Programmer - thanks for your reply.

The full link for the MDM-1 demo analog1.c software is:

ps sorry if this is repeat - not sure the original reply worked!

To get rid of the errors, do these changes:

1. In the Analog1.c file, add the 'void' keyword to main():

Thanks - I had sussed the need to add the void to the main rfunction.

I deleted the 8 'external' references in the mdm.h file but now get the following error:

---------------------------------------------------------------------------------
Executing: "C:\CCS\Ccsc.exe" +FM "mdm.c" +EXPORT +DF +LN +T +A +M +Z +Y=9 +EA
*** Error 128 "mdm.c" Line 31(1,1): A #DEVICE required before this line
1 Errors, 0 Warnings.
Halting build on first failure as requested.
----------------------------------------------------------------------------------

I'm now using latest version (4.085) - did you get the above error?

I then tried inserting the default #device CONST=ROM statement into the analog1.c, which produces the same error.

Inserting #device CONST=READ_ONLY, produces the following error:

--------------------------------------------------------------------------------
>>> Warning 203 "analog1.c" Line 56(1,1): Condition always TRUE
*** Error 74 "analog1.c" Line 107(0,1): Not enough RAM for all variables
1 Errors, 2 Warnings.
Halting build on first failure as requested.
----------------------------------------------------------------------------------

Is there another #device statement that the compiler is expecting?

The MPLAB project should have only one file in "Source Files" list on the
left side of the screen. This one:

Thanks a million PCM Programmer - that's fixed it.

That's something else I've learned today!
