Conditional default config's

[cncmachineguy]

Thanks Darrel. I suppose that is what Dave was pointing at, but I didn't get it. That will do what I want, (be able to use defaults conditionally). So we CAN pass things to the .BAS just not the .INC?

Now to refresh the python skills or work on liberty basic and parse the files so I can be lazy and not do it by hand. OK I know it will be far easier to just open the files and change them. But what will I learn that way??

That is not what I was thinking.
I did not know
DEFINE CONFIGOVERRIDE
even existed.

Thanks Darrel!

Hi Dave,
I don't think

DEFINE CONFIGOVERIDE

is a pre existing anything. I think it could have been

DEFINE BERTISLAZY

and have the same effect. In the .CFG file, the

ifndef CONFIGOVERIDE
or
ifndef BERTISLAZY

tells PBP or MPASM (not clear here) to see if the DEFINE exists. If not then do the following code. If it does exist then endif.

I am going to have a play with this and verify this is how it works. I will report back if anyone is intrested.

BTW, the reason I want this is so I can test forum code that uses the default config's, without having to change things all the time for my own code.

I am interested.

DEFINE's are currently only passed on to the assembler unchanged, and do not directly affect PBP code.

Those DEFINES are added to the ASM after the .inc file, but before the .bas file.
This allows them to affect the library code that is included from the .bas file, but the items in the .inc file have already been processed.

The example above was for an 18F.
For a 16F, the .cfg file should be a little different

' -- 16F877a.cfg --
ASM
  ifndef PM_USED
    ifndef CONFIGOVERRIDE
      __config _XT_OSC & _WDT_ON & _LVP_OFF & _CP_OFF
    endif
  endif
ENDASM

The usage in the main program is essentially the same.

DEFINE CONFIGOVERRIDE
@      __config _HS_OSC & _WDT_ON & _LVP_OFF & _CP_OFF

A better method has been developed by Charles and Leonard that allows defaults to be overridden automatically, and the new style CONFIG statements to be used in your programs as well.
It will be available in the coming months, so you may not want to spend to much time editing all the files.

Hi, Darrel

Petty good news !!! re-Commenting defaults @ each PBP patch release became a bit boring ...

Oh too cool!!! Does this count as me getting my wish?
